____________________________________________________


As a volunteer medical layman information activist for aspartame toxicity and
related issues for nine years, during the last 5 years I have reviewed over two
dozen quality positive abstracts on stevia safety, and daily use about 1 tsp
green stevia powder myself, with no problems.

Reports of symptoms by users are extremely rare on the Net, while some reject
the taste.

Years ago, I encouraged the use of sucralose, only to find that its safety has
never been confirmed by adequate studies on humans, a substantial fraction of
its complex metabolites remains in the body, and there are increasing reports on
the Net of alarming symptoms.

Are these dozen studies science or yet another consummate industry propaganda
blitz, as has been the case for aspartame, neotame, sucralose, and Acesulfame-K?

If science, then financing has to be explicit, the authors, their resumes, and
full contact details listed, and, all texts put for free in the public domain.

All evidence and research re aspartame, stevia, and other sweetener toxicity
should be made fully and conveniently available for free.

The huge corporations and government agencies responsible for the major public
health debacle and cover up re aspartame rightfully should set up a hundred
billion dollar fund for compensation of injured citizens.

The evidence shows that stevia affects blood pressure and glucose. Therefore,
this is a drug. Few drugs indeed have no bad effects for some or many users.

All toxicity research has to be subject to fierce, reason and evidence based
public scrutiny and debate, open to all citizens, fully archived and searchable,
along with a perpetual record of all citizen and expert negative reports.

The authors of the dozen studies have strong conflicts of interest:

AG Renwick, AR Boobis, and GW Williams are defenders of aspartame, while many of
these authors work for Coca-Cola, Cargill, and Cantox, a dedicated industry
consultancy.

DJ Brusic ( an "independent toxicologist" ) and GW Williams are authors, both
members of Cantox and on the International Editorial Board of Food and Chemical
Toxicology.

AR Boobis is editor of Food Chemical Toxicology.

BA Magnuson and GW Williams of Cantox were authors of a massive, spurious review
in 2007, financed by Ajinomoto, that exonerated aspartame:

and/or crucial pieces of information are left out.

In addition to the misrepresentation of the research,
readers (including medical professionals) are often not told that
this review was funded by the aspartame manufacturer, Ajinomoto,
and the reviewers had enormous conflicts of interest."

Aspartame is a widely used artificial sweetener that has been linked
to pediatric and adolescent migraines.

Upon ingestion, aspartame is broken, converted, and oxidized into
formaldehyde in various tissues.

We present the first case series of aspartame-associated migraines
related to clinically relevant positive reactions to formaldehyde on
patch testing. PMID: 18627677

Patients with a contact dermatitis to formaldehyde have been seen to

Systemic exposure to allergens resulting in a cutaneous eruption is
known as systemic contact dermatitis (SCD).

Once sensitization occurs, varying exposures to antigens via multiple
routes (including transepidermal routes, intravenous or intramuscular
routes, inhalation, and ingestion) can result in systemic flare.

This article highlights the different categories of common
contactants, metals, medications, and plants, exposure to which leads
to SCD.

A comprehensive approach that takes into account all possible routes
of exposure is essential in diagnosing SCD and in helping patients
successfully avoid their allergens. PMID: 18346390

"Our patient underscores the importance of appropriate patch testing
and education.

Once we identified the allergy to formaldehyde and quaternium-15, we
provided patient education materials regarding the common and not-so-
common locations of these chemicals and cross-reactors.

We also gave the patient information on avoidance and safe
alternatives (see Table 5).

Fortunately, with technical advances, this student completed the
anatomy section via electronic learning tools.

By avoiding formaldehyde, including anatomy lab, FRP in her shampoo
and cosmetics, and aspartame in her diet, this patient dramatically
improved.

As with all contact dermatitides, the mainstay of treatment for
allergic contact dermatitis is avoidance."

http://www.eczemacenter.org/eczema_center/index.htm

Atopic dermatitis (AD) -- better known as eczema -- is the most common
chronic skin disorder seen in infants and children.
In fact, the prevalence of this condition has risen dramatically
during the last three decades.
Currently, 15% to 20% of children in the United States are expected to
experience this condition sometime during their lifetime, compared to
7% around 1960.

The negative impact of eczema is profound and insidious.
It affects both the patient who suffers from it and that patient's
family members, and it does so on two important levels -- physical and
emotional.

Physical:

Inflamed, itchy rashes can involve any and all of the skin surfaces
and are frequently complicated by skin breakdown and bacterial, viral,
and fungal infections.

It is linked to the development of life-long allergic conditions,
including asthma, food allergies, and rhinitis.

Any level of AD is extremely uncomfortable and, at times, painful.
Individuals with moderate to severe disease report that eczema hugely
disturbs their sleep and impacts performance of daily activities,
including adverse effects on school, sports activities, work, and peer
relationships.

In studies, individuals with eczema reported more negative impact on
quality of life than those with insulin-dependent diabetes!

Emotional:

Patients and their families experience considerable emotional
distress, anxiety, and embarrassment because of people's response to
this illness.

In fact, the emotional scarring on both patient and family members may
outlast eczema's physical effects.

Parents especially suffer because it is difficult for children
experiencing this condition to understand that their parents cannot
make the torment go away.
The stress of caring for these children is even greater than parents
caring for a child with insulin-dependent diabetes.

Patients experience considerable discrimination and social isolation
because of this illness.
People often stare, shiver with disgust or step back in fear from
those who have this condition.
The end result for patients: A life-time of struggle with their sense
of worth and self esteem.

similar levels of daily formaldehyde and formic acid, causes of birth
defects, come from cigarettes, aspartame, and dark wines and liquors
-- folic acid protects most people: Rich Murray 2008.07.15

http://www.divine.ca/en/health-and-wellness/articles/c_16_i_3295/5-reasons-to-qu
it-smoking-1.html

"A smoker who goes through one pack a day will smoke 7,300 cigarettes
a year, inhaling the equivalent of nearly 1 gram of formaldehyde
(yikes!)."

That's about 2.5 mg daily formaldehyde intake for 20 cigarettes, over
the 2 mg USA FDA alarm level for formaldehyde in average 2 liters
daily drinking water, while a single 12 oz can of diet soda also
results in about 2 mg formaldehyde toxic products in the body,
including formic acid, a notorious cause of birth defects.

Dark wines and liquors usually supply even more methanol, which the
body always turns into formaldehyde and formic acid -- the major cause
of "morning after" hangovers.

High levels of folic acid, a safe, affordable vitamin in fruits and
vegetables, largely prevents formaldehyde and formic acid toxicity in
most people.

It is certain that high levels of aspartame use, above 2 liters daily
for months and years, must lead to chronic formaldehyde-formic acid
toxicity.

Fully 11 % of aspartame is methanol -- 1,120 mg aspartame in 2 liters
diet soda, almost six 12-oz cans, gives 123 mg methanol (wood
alcohol). The methanol is immediately released into the body after
drinking .
Within hours, the liver turns much of the methanol into formaldehyde,
and then much of that into formic acid, both of which in time are
partially eliminated as carbon dioxide and water.

However, about 30 % of the methanol remains in the body as cumulative
durable toxic metabolites of formaldehyde and formic acid -- 37 mg
daily, a gram every month, accumulating in and affecting every tissue.

If only 10 % of the methanol is retained daily as formaldehyde, that
would give 12 mg daily formaldehyde accumulation -- about 60 times
more than the 0.2 mg from 10 % retention of the 2 mg EPA daily limit
for formaldehyde in drinking water.

Bear in mind that the EPA limit for formaldehyde in drinking water is
1 ppm, or 2 mg daily for a typical daily consumption of 2 liters of
water.

The FEMA trailers give about the same amount of formaldehyde and
formic acid daily as from a quart of dark wine or liquor, or two
quarts (6 12-oz cans) of aspartame diet soda, from their over 1 tenth
gram methanol impurity (one part in 10,000), which the body quickly
makes into formaldehyde and then formic acid -- enough to be the major
cause of "morning after" alcohol hangovers.

Methanol and formaldehyde and formic acid also result from many fruits
and vegetables, tobacco and wood smoke, heater and vehicle exhaust,
household chemicals and cleaners, cosmetics, and new cars, drapes,
carpets, furniture, particleboard, mobile homes, buildings, leather...
so all these sources add up and interact with many other toxic
chemicals.

Maternal exposure to folic acid antagonists increases risks

Exposure to folic acid antagonists during pregnancy is associated with a higher
risk of placenta-mediated adverse outcomes such as preeclampsia, placental
abruption, fetal growth restriction or fetal death reports a retrospective
cohort study published in CMAJ
http://www.cmaj.ca/press/pg1263.pdf .

Folic acid antagonists include a broad range of drugs used to treat epilepsy,
mood disorders, hypertension and infections. As approximately 50% of pregnancies
in industrialized countries like Canada are unplanned, there is a risk of
unintended exposure to these medications.

The study, conducted by researchers from Ottawa, Montreal, Saskatoon and Hunan,
China looked at 14,982 women who had taken folic acid antagonists one year prior
to delivery and 59,825 women who did not. Dr. Shi Wu Wen and co- researchers
found that maternal exposure to folic acid antagonists was associated with a
slightly higher risk of adverse pregnancy outcomes. They suggest re-classifying
some folic acid antagonists and recommend increased folic acid supplements for
women requiring folic acid antagonists during pregnancy.

In a related commentary http://www.cmaj.ca/press/pg1243.pdf , Dr. Joel Ray
suggests the research study presents some "thought-provoking findings, but the
results may not be ready for adoption by clinical practitioners or drug policy
makers." He cites some real concerns with the study design and the need for
clinically relevant finding as cautions about translating findings into
practice.

Folic Acid Antagonists during Pregnancy and the Risk of Birth Defects
Sonia Hernández-Díaz, M.D., Dr.P.H., Martha M. Werler, Sc.D., Alexander M.
Walker, M.D., Dr.P.H., and Allen A. Mitchell, M.D.

ABSTRACT

Background
Multivitamin supplementation in pregnant women may reduce the risks of
cardiovascular defects, oral clefts, and urinary tract defects in their infants.
We evaluated whether the folic acid component of multivitamins is responsible
for the reduction in risk by examining the associations between maternal use of
folic acid antagonists and these congenital malformations.

Methods
We assessed exposure to folic acid antagonists that act as dihydrofolate
reductase inhibitors and to certain antiepileptic drugs in 3870 infants with
cardiovascular defects, 1962 infants with oral clefts, and 1100 infants with
urinary tract defects and also in 8387 control infants with malformations the
risk of which is not reduced after vitamin supplementation. Mothers were
interviewed within six months after delivery about their medication use during
pregnancy.

Results
The relative risks of cardiovascular defects and oral clefts in infants whose
mothers were exposed to dihydrofolate reductase inhibitors during the second or
third month after the last menstrual period, as compared with infants whose
mothers had no such exposure, were 3.4 (95 percent confidence interval, 1.8 to
6.4) and 2.6 (95 percent confidence interval, 1.1 to 6.1), respectively. The
relative risks of cardiovascular defects, oral clefts, and urinary tract defects
after maternal exposure to antiepileptic drugs were 2.2 (95 percent confidence
interval, 1.4 to 3.5), 2.5 (95 percent confidence interval, 1.5 to 4.2), and 2.5
(95 percent confidence interval, 1.2 to 5.0), respectively. Use of multivitamin
supplements containing folic acid diminished the adverse effects of
dihydrofolate reductase inhibitors, but not that of antiepileptic drugs.

Conclusions
Folic acid antagonists, which include such common drugs as trimethoprim,
triamterene, carbamazepine, phenytoin, phenobarbital, and primidone, may
increase the risk not only of neural-tube defects, but also of cardiovascular
defects, oral clefts, and urinary tract defects. The folic acid component of
multivitamins may reduce the risks of these defects.

Abstract

Background:
Methanol is endogenously formed in the brain and is present as a congener in
most alcoholic beverages.

Because ethanol is preferentially metabolized over methanol (MeOH) by
alcohol dehydrogenase, it is not surprising that MeOH accumulates in the
alcohol-abusing population.

This suggests that the alcohol-drinking population will have higher levels
of MeOH's neurotoxic metabolite, formic acid (FA).

FA elimination is mediated by folic acid.

Neurotoxicity is a common result of chronic alcoholism.

This study shows for the first time that FA, found in chronic alcoholics, is
neurotoxic and this toxicity can be mitigated by folic acid administration.

Objective:
To determine if FA levels are higher in the alcohol-drinking population and
to assess its neurotoxicity in organotypic hippocampal rat brain slice
cultures.

Methods:
Serum and CSF FA was measured in samples from both ethanol abusing and
control patients, who presented to a hospital emergency department. [ CSF =
Cerebral Spinal Fluid ]

FA's neurotoxicity and its reversibility by folic acid were assessed using
organotypic rat brain hippocampal slice cultures using clinically relevant
concentrations.

Results:
Serum FA levels in the alcoholics (mean ± SE: 0.416 +- 0.093 mmol/l, n = 23)
were significantly higher than in controls (mean ± SE: 0.154 +- 0.009
mmol/l, n = 82) (p < 0.0002).

FA was not detected in the controls' CSF (n = 20), whereas it was >0.15
mmol/l in CSF of 3 of the 4 alcoholic cases.

Low doses of FA from 1 to 5 mmol/l added for 24, 48 or 72 hours to the rat
brain slice cultures caused neuronal death as measured by propidium iodide
staining.

When folic acid (1 umol/l) was added with the FA, neuronal death was
prevented. [ umol = micromole ]

Conclusions:
Formic acid may be a significant factor in the neurotoxicity of ethanol
abuse.

This neurotoxicity can be mitigated by folic acid administration at a
clinically relevant dose.

NEUROTOXICITY AND BRAIN damage are common concomitants findings of chronic
alcoholism (Carlen and Wilkinson, 1987; Carlen et al., 1981; Harper, 2007).

The cause of ethanol-induced neurotoxicity is still unclear.

We present here a novel hypothesis for neurotoxicity: increased formic acid
(FA) levels produced from methanol (MeOH), whose catabolism is blocked by
ethanol.

Axelrod and Daly (1965) demonstrated the endogenous formation of MeOH from
S-adenosylmethionine (SAM) in the pituitary glands of humans and various
other mammalian species.

Presence of MeOH in the breath of human subjects was reported by Ericksen
and Kulkarni (1963).

Most alcoholic beverages also have a small amount of MeOH as a congener
(Sprung et al., 1988).

As ethanol (EtOH) has a higher affinity for alcohol dehydrogenase (ADH) than
MeOH, EtOH is preferentially metabolized (Mani et al., 1970).

As a result, MeOH accumulation from endogenously produced MeOH, and/or, that
consumed as part of an alcoholic beverage, has been reported in
concentrations up to 2 mmol/l in heavy drinkers (Majchrowicz and Mendelson,
1971).

Toxicity resulting from MeOH consumption is extensively documented in both
humans and animals and has been attributed to its metabolite, FA (Benton and
Calhoun, 1952; Roe, 1946, 1955; Wood, 1912; Wood and Buller, 1904).

The rate of formate oxidation and elimination is dependent on adequate
levels of hepatic folic acid, particularly hepatic tetrahydrofolate (THF)
(Johlin et al., 1987; Tephly and McMartin, 1974).

Significantly higher formate levels were obtained when folate-deficient
animals were exposed to MeOH as compared with folate-sufficient animals (Lee
et al., 1994; McMartin et al., 1975; Noker et al., 1980).

To understand ethanol's toxicity, one must consider FA produced from MeOH,
and its elimination mediated by folic acid.

We postulate that in the chronically drinking patient, we will find higher
levels of FA than in the nondrinking population, and that formate is
neurotoxic.

We also hypothesize that treatment with folic acid, which is a critical
factor in the catabolism of FA, can prevent or diminish FA neurotoxicity.

Clinical evaluation of patients with complaints related to formaldehyde
exposure.
H R Imbus

Formaldehyde is a very widely used chemical in our present society and one with
which every physician has had a first-hand experience in his early days of
training in the anatomy laboratory. The National Institute of Occupational
Safety and Health lists 52 occupations that expose people to formaldehyde. In
recent years, however, the increasing use of formaldehyde resins in the
production of building materials such as particleboard and urea-formaldehyde
foam insulation has resulted in exposures of large numbers of people in
nonoccupational settings. Consumer products such as cosmetics, cigarettes,
textiles, furniture, draperies, and preservatives release formaldehyde. It is
present in the outdoor atmosphere from products of combustion and automobile
exhaust and likewise in the home from such things as gas cooking. These more
widespread and increased exposures have resulted in concern regarding potential
health effects. Therefore, it is likely that physicians have or will encounter
patients who wish evaluations of a present or potential health effect from
formaldehyde. This article is for the purpose of providing assistance in such
evaluation.

[ This layman review gives detailed access to the gist of six
epidemiological studies since 2004, two in 2007, that show correlations of diet soda (largely aspartame) with health issues.

Probably studies of the correlations at the top 0.1 to 1.0 % level of use over periods of years by people in vulnerable groups are needed.

The Nurses Health Study is a bonanza of information about the health of probably hundreds of nurses who use 6 or more cans daily of diet soft drinks -- they have also stored blood and tissue samples from their immense pool of subjects, over 100,000 for decades.

In total, there are 19 mainstream studies about negative effects with aspartame since summer, 2005, listed in this review, included many about the detailed biochemistry involved. ]

19,000 people, the 4% of users of aspartame who drink average 5 cans daily, have more problems in NIH AARP study of 474,000 people: Murray 2007.09.21

This is the first good data about the percentage of aspartame users who
use over 3 cans daily, averaging 5 cans daily at 200 mg per 12 oz can
diet soda.

About 4% of 473,984 is 19,000 people, with a peak intake of 17 cans
daily, and average 5 cans daily.

It would be worthwhile to investigate a wide variety of symptoms for the
0.1% of highest level users, about 500 people.

For about 200 million USA aspartame users, this would be 200,000 people.

Table 1 reveals consistent increase in problems from

--------------------- zero to (400 - 600) to (over 600) mg/d
aspartame intake:

% of cohert ---------- 46 -------- 5 -------- 4 %

mean aspartame mg/d --- 0 -------441 ------ 986

16+ education -------- 37 ------- 40 ------- 34 %

diabetes history ------ 3 ------- 22 ------- 26 %

alcohol g/d ---------- 14 ------- 11 ------- 13

never smoke ---------- 36 ------- 31 ------- 29 %

Body Mass Index ------ 26 ------- 29 ------- 29

18.5 - 25 ------------ 42 ------- 21 ------- 19 %

30 - 35 -------------- 13 ------- 23 ------- 26 %

over 35 --------------- 4 ------- 10 ------- 13 %

Physical activity %:

under 3-4/mo --------- 32 ------- 32 ------- 37 %

under 1-2/wk --------- 22 ------- 21 ------- 19 %

over 3-4/wk ---------- 45 ------- 45 ------- 43 %

Calories kcal ----- 1,919 ---- 1,855 ---- 2,044 %

Caffeine mg/d ------- 393 ------ 364 ------ 424

There do seem to be many increases of problems
from the second to third row, as mean aspartame use doubles.

Granted, this is cherry picking the data, selecting interesting patterns.

Correlations alone do not prove any direction of causation.

Nevertheless, it may be of value to study the correlations for
increasing aspartame intake among the 4 % using over 600 mg, the
equivalent of 3 cans 12-oz cans diet soda daily.
The average use for this group is 5 cans daily.

For instance, are a minority of these heavy users displaying the great
majority of the problems that are reflected in the mean for each level
of use, with most users only having little or no increase in problems?

This is a group of about 20,000 people.

"We cannot exclude the possibility that higher aspartame consumption
than that observed in this study may be associated with an elevated risk
of hematopoietic or brain cancers."

BACKGROUND:
In a few animal experiments, aspartame has been linked to hematopoietic
and brain cancers.

Most animal studies have found no increase in the risk of these or other
cancers.

Data on humans are sparse for either cancer.

Concern lingers regarding this widely used artificial sweetener.

OBJECTIVE:
We investigated prospectively whether aspartame consumption is
associated with the risk of hematopoietic cancers or gliomas (malignant
brain cancer).

METHODS:
We examined 285,079 men and 188,905 women ages 50 to 71 years in the
NIH-AARP Diet and Health Study cohort

Daily aspartame intake was derived from responses to a baseline
self-administered food frequency questionnaire that queried consumption
of four aspartame-containing beverages (soda, fruit drinks, sweetened
iced tea, and aspartame added to hot coffee and tea) during the past year.

Histologically confirmed incident cancers were identified from eight
state cancer registries.

Multivariable-adjusted relative risks (RR) and 95% confidence intervals
(CI) were estimated using Cox proportional hazards regression that
adjusted for age, sex, ethnicity, body mass index, and history of diabetes.

RESULTS:
During over 5 years of follow-up (1995-2000), 1,888 hematopoietic
cancers and 315 malignant gliomas were ascertained.

Higher levels of aspartame intake were not associated with the risk of
overall hematopoietic cancer
(RR for >/=600 mg/d, 0.98; 95% CI, 0.76-1.27),
glioma (RR for >/=400 mg/d, 0.73; 95% CI, 0.46-1.15;
P for inverse linear trend = 0.05),
or their subtypes in men and women.

CONCLUSIONS:
Our findings do not support the hypothesis that aspartame increases
hematopoietic or brain cancer risk. PMID: 16985027

"We cannot exclude the possibility that higher aspartame consumption
than that observed in this study may be associated with an elevated risk
of hematopoietic or brain cancers.

In the laboratory study with positive findings, animals were fed doses
starting from 4 mg up to 5,000 mg per kg body weight.

Significantly elevated lymphomas and leukemias were observed in female
rats fed 20 mg of aspartame and higher (e.g., 1,200 mg for humans
weighing 60 kg or 132 lb; refs. 13, 14).

The reported aspartame intake in our data ranged from 0 to 3,400 mg/d
with sparse numbers in the upper intake categories
(1,200 or 2,000 mg/d, which is equivalent to ~7 to 11 cans of soft
drinks daily) compared with the lowest categories,
and the associations were similarly null in both men and women."

"Individuals who drank more than 1 can/week of artificially sweetened
(but not sugar-sweetened) soft drink (cola and other) had an 8 %
increased risk (95 % CI: 1.01-1.16)."

"The increased death risk with consumption of artificially sweetened,
but not sugar-sweetened, soft drinks suggests an effect of the sweetener
rather than other components of the soft drinks, although residual
confounding remains a possibility."

Non-alcoholic beverage and caffeine consumption and mortality: the
Leisure World Cohort Study.

University of Southern California, CA, USA.

OBJECTIVE:
To examine the effects of non-alcoholic beverage and caffeine
consumption on all-cause mortality in older adults.

METHODS:
The Leisure World Cohort Study is a prospective study of residents of a
California retirement community.

A baseline postal health survey included details on coffee, tea, milk,
soft drink, and chocolate consumption.

Participants were followed for 23 years (1981-2004).

Risk ratios (RRs) of death were calculated using Cox regression for 8644
women and 4980 men (median age at entry, 74 years) and adjusted for age,
gender, and multiple potential confounders.

RESULTS:
Caffeine consumption exhibited a U-shaped mortality curve.

Moderate caffeine consumers had a significantly reduced risk of death
(multivariable-adjusted RR = 0.94, 95 % CI: 0.89, 0.99 for 100-199 mg/day
and RR = 0.90, 95 % CI: 0.85, 0.94 for 200-399 mg/day
compared with those consuming <50 mg/day).

Individuals who drank more than 1 can/week of artificially sweetened
(but not sugar-sweetened) soft drink (cola and other) had an 8 %
increased risk (95 % CI: 1.01-1.16).

Neither milk nor tea had a significant effect on mortality after
multivariable adjustment.

CONCLUSIONS:
Moderate caffeine consumption appeared beneficial in reducing risk of death.

Attenuation in the observed associations between mortality and intake of
tea and milk with adjustment for potential confounders suggests that
such consumption identifies those with other mortality-associated
lifestyle and health risks.

The increased death risk with consumption of artificially sweetened, but
not sugar-sweetened, soft drinks suggests an effect of the sweetener
rather than other components of the soft drinks, although residual
confounding remains a possibility. PMID: 17275898

BACKGROUND:
modifiable behavioural risk factors including smoking and alcohol
consumption are major contributing or actual causes of mortality.

OBJECTIVE:
to examine the effect of alcohol intake on all-cause mortality in older
adults.

Design and SETTING:
prospective population-based cohort study of residents of a California,
United States retirement community.

SUBJECTS:
8,877 women and 5,101 men (median age, 74 years) who in the early 1980s
completed a postal health survey incluing details on alcohol consumption.

METHODS:
participants were followed for 23 years (1981-2004) including two
follow-up questionnaires (in 1992 and 1998) asking about current alcohol
intake.

Age-adjusted and multivariate-adjusted risk ratios of death and 95 %
confidence intervals were calculated separately for men and women, using
proportional hazard regression.

RESULTS:
of the 8,644 women and 4,980 men with complete information on the
variables of interest and potential confounders,
6,930 women and 4,456 men had died (median age, 87 years).

Both men and women who drank alcohol had decreased mortality compared
with non-drinkers.

Those who drank two or more drinks per day had a 15 % reduced risk of death.

The reduced risk was not limited to one type of alcohol.

Stable drinkers (those who reported drinking both at baseline and
follow-up) had a significantly decreased risk of death compared with
stable non-drinkers.

Those who started drinking at follow-up also had a significantly lower risk.

Women who quit drinking were at increased risk of death.

CONCLUSION:
in elderly men and women, moderate alcohol intake exhibits a beneficial
effect on mortality.

Those who quit may do so for health reasons that affect mortality.

" Analyses that used food frequency questionnaire data suggested that
intake of over 1 drink per day of either regular or diet soft drinks was
associated with a over 50% higher incidence of metabolic syndrome
compared with intake of under 1 soft drink per week.

" Although the association of high fructose corn syrup intake and
insulin resistance may be a contributory mechanism, 31 in the present
study, both regular and diet soft drinks appeared to pose similar
metabolic hazards,
which suggests that other factors may be operational. "

" The caramel content of both regular and diet drinks may be a potential
source of advanced glycation end products, 5 which may promote insulin
resistance 36 and can be proinflammatory. 37 "

" It is conceivable, though,
that there may be residual confounding caused by lifestyle factors not
adjusted for in the present analyses. "

" As noted above, it is conceivable that residual confounding by
lifestyle/dietary factors not adjusted for may have contributed to the
metabolic risks associated with soft drink intake. "

" The similar metabolic hazard posed by both regular and diet soft
drinks is noteworthy given the lack of calories in the latter; however,
other studies have also reported associations of diet soft drinks with
weight gain in boys 29 and with hypertension in adult women. 7 "

BACKGROUND:
Consumption of soft drinks has been linked to obesity in children and
adolescents, but it is unclear whether it increases metabolic risk in
middle-aged individuals.

METHODS AND RESULTS:
We related the incidence of metabolic syndrome and its components to
soft drink consumption in participants in the Framingham Heart Study
(6,039 person-observations, 3,470 in women; mean age 52.9 years) who
were free of baseline metabolic syndrome.

Metabolic syndrome was defined as the presence of over of the following:

waist circumference over 35 inches (women) or over 40 inches (men);
fasting blood glucose over 100 mg/dL;
serum triglycerides over 150 mg/dL;
blood pressure over 135/85 mm Hg;
and high-density lipoprotein cholesterol under 40 mg/dL (men)
or under 50 mg/dL (women).

Multivariable models included adjustments for age, sex, physical
activity, smoking, dietary intake of saturated fat, trans fat, fiber,
magnesium, total calories, and glycemic index.

Cross-sectionally, individuals consuming over 1 soft drink per day had a
higher prevalence of metabolic syndrome
(odds ratio [OR], 1.48; 95 % CI, 1.30 to 1.69)
than those consuming under 1 drink per day.

On follow-up (mean of 4 years), new-onset metabolic syndrome developed
in 765 (18.7 %) of 4095 participants consuming under 1 drink per day and
in 474 (22.6 %) of 2059 persons consuming over 1 soft drink per day.

Consumption of over 1 soft drink per day
was associated with increased odds of developing
metabolic syndrome (OR, 1.44; 95% CI, 1.20 to 1.74),
obesity (OR, 1.31; 95 % CI, 1.02 to 1.68),
increased waist circumference (OR, 1.30; 95 % CI, 1.09 to 1.56),
impaired fasting glucose (OR, 1.25; 95% CI, 1.05 to 1.48),
higher blood pressure (OR, 1.18; 95 % CI, 0.96 to 1.44),
hypertriglyceridemia (OR, 1.25; 95 % CI, 1.04 to 1.51), and
low high-density lipoprotein cholesterol
(OR, 1.32; 95 % CI 1.06 to 1.64).

CONCLUSIONS:
In middle-aged adults, soft drink consumption is associated with a
higher prevalence and incidence of multiple metabolic risk factors.

* Introduction

Several reports from the United States and Europe indicate increasing
consumption of soft drinks among children, adolescents, and adults over
the past 3 decades. 1,2

Many clinical studies have linked the rising consumption of soft drinks
to the present epidemic of obesity and diabetes mellitus among children
and adolescents 3–6 and to the development of hypertension in adults. 7

Furthermore, added sweeteners in soft drinks have been linked to an
increase in serum triglycerides levels in some reports 8,9 but not in
others. 10,11

The association of soft drink consumption with obesity and higher
insulin resistance has been attributed to multiple factors, including
greater caloric intake, the high fructose corn syrup content, 12 less
satiety and compensation, and a general effect of consuming refined
carbohydrates (see review by Drewnowski and Bellisle 13).

The aforementioned data raise the possibility that the consumption of
soft drinks can fuel metabolic derangements, including insulin
resistance, that can translate into a greater risk of developing
abdominal obesity, high triglyceride levels, low levels of high-density
lipoprotein cholesterol (HDL-C), elevated blood pressure, and impaired
glucose tolerance; this constellation of metabolic traits has been
collectively referred to as the metabolic syndrome. 14

Higher prevalence of the metabolic syndrome poses greater risk for
cardiovascular disease in the community, 15 although the independent
contribution of this entity to vascular risk beyond its components has
been questioned 16

In the present prospective investigation, we tested the hypothesis that
greater soft drink consumption increases the risk of developing
metabolic risk factors (alone and in combination [metabolic syndrome])
in middle-aged adults in the community.

Additionally, we evaluated whether metabolic risk varied on the basis of
consumption of sugar-sweetened ("regular") versus artificially sweetened
("diet") soft drinks.

* Methods

Study Sample

The Framingham Heart Study began in 1948 with the enrollment of 5,209
participants into the original study cohort. 17

In 1971, children of the original cohort participants and the spouses of
the children were enrolled into the Framingham Offspring Study (n=5,124). 18

Offspring study participants are evaluated approximately every 4 years.

Information on daily consumption of soft drinks was collected via a
physician-administered questionnaire at each study visit from the fourth
(1987–1991) through the sixth (1995–1998) examination cycles.

That examination questionnaire did not elicit information regarding
consumption of regular versus diet soft drinks; however, such
information was available from the self-administered food frequency
questionnaires (FFQ; Willett questionnaire) 19 completed by participants
at the fifth (1992–1995) and sixth examination cycles (see below).

For the present investigation, we selected offspring cohort participants
who attended any 2 consecutive examinations from the fourth through the
seventh (1998–2001) examination cycles.

We excluded participants with missing data on covariates (n = 207) and
those with prevalent cardiovascular disease (n = 926).

After exclusions, a total of 8997 person-observations (4871 in women)
were eligible for the cross-sectional analyses.

For prospective analyses, we excluded individuals with baseline
metabolic syndrome (n = 2897 person-observations; metabolic syndrome as
defined below) and those with any missing metabolic syndrome components
on follow-up (n = 61 person-observations).

The schema for selection of individuals eligible for cross-sectional and
longitudinal analyses is displayed in the Figure.

All participants provided written informed consent, and the protocol for
the study was approved by institutional review board of Boston Medical
Center.

Measurement of Covariates

At each Framingham Heart Study examination, participants provided a
medical history and underwent a complete standardized physical
examination that included anthropometry, blood pressure measurements,
and laboratory assessment of vascular risk factors.

Fasting levels of blood glucose, triglycerides, and HDL-C were measured
with standard assays.

Blood pressure was measured by a physician using a mercury
sphygmomanometer and with the participant resting in a seated position
for 5 minutes; the average of 2 readings obtained on the participant’s
left arm constituted the examination blood pressure.

Physical activity was assessed by calculating a "physical activity
index"; participants were asked specific questions regarding how many
hours in a typical day they spent sitting, sleeping, or performing
light-moderate or heavy physical activities. 20

Alcohol intake was assessed by averaging the number of alcoholic
beverages consumed per week.

Participants who reported smoking 1 or more cigarettes per day in the
year before the Framingham Heart Study examination were considered
current smokers.

Assessment of Soft Drink Consumption and Dietary Intake of Other Foods

At the index examinations, participants reported the average number of
12-oz servings of soft drinks (Coke, Pepsi, Sprite, or other carbonated
soft drinks, separately categorized into caffeinated or decaffeinated
drinks) consumed per day in the year preceding the examination.

The responses to the questions were entered as integers (0 or more)
separately for caffeinated and decaffeinated soft drinks.

This questionnaire (referred to as the "examination cola questionnaire")
did not separate nondrinkers from infrequent drinkers (<1 drink per day).

Accordingly, we compared individuals who reported consuming 1, over 1,
or over 2 soft drinks per day with attendees who reported consuming
under 1 soft drink per day (infrequent drinkers and nondrinkers, who
served as the referent).

Intake of regular and diet soft drinks was assessed from FFQs 19 that
were administered at the fifth and sixth examinations.

We also assessed the dietary information on consumption of total
calories, saturated fat, trans fat, fiber, magnesium, and glycemic index
from the FFQ. 19

Because a FFQ was not administered at the fourth examination cycle,
dietary covariate data from the fifth examination cycle were used for
analyses using information from the examination cola questionnaire at
all 3 examinations.

Data from the FFQ were considered valid only if total energy intakes
reported were over 2.51 MJ/d (600 kcal/d) for men and women but under
17.54 MJ/d (4200 kcal/d) for men or under 16.74 MJ/d (4000 kcal/d) for
women and if fewer than 13 food items were left blank.

Each food item was categorized in 9 categories that ranged from never or
under 1 serving per month to over 6 servings per day.

For assessment of saturated fat, trans fat, or dietary fiber, the
nutrient intakes from all specific food items were multiplied by the
frequency of consumption.

The validity of the FFQ has been demonstrated previously. 21

Definition and Components of the Metabolic Syndrome

The metabolic syndrome was considered present if 3 or more of the
following individual components were present 14,22:
waist circumference over 35 inches (88 cm) for
or over 40 inches (102 cm) for men;
fasting blood sugar over 100 mg/dL (5.5 mmol/L) or treatment with oral
hypoglycemic agents or insulin;
blood pressure over 135/85 mm Hg or treatment for hypertension;
serum triglycerides over 150 mg/dL (1.7 mmol/L)
or treatment for hypertriglyceridemia (with niacin or fibrates);
and HDL-C under 40 mg/dL (1.03 mmol/L) in men
or under 50 mg/dL (1.3 mmol/L) in women.

Statistical Analyses

Age- and sex-adjusted baseline characteristics of the participant groups
defined according to the number of soft drinks consumed in 1 day
(under 1, 1, or over 2 per day) were compared by multiple linear and
multiple logistic regression analysis for continuous and categorical
characteristics, respectively.
Data on consumption of soft drinks at each of the 3 eligible baseline
examinations (examination cola questionnaire) were used for this purpose.
Tests for trend in baseline characteristics across soft drink
consumption categories were performed with multiple regression.
We also assessed the baseline characteristics after excluding
participants with prevalent metabolic syndrome at baseline
examinations (sample used for incidence analyses; see below).

Soft Drink Consumption and Prevalence of the Metabolic Syndrome

We used data from examinations 4, 5, and 6 (examination cola
questionnaire) and generalized estimating equations to compare the
prevalence of metabolic syndrome in participants who consumed over 1
soft drink per day with those who consumed under 1 soft drink per day
(referent).
Each participant could contribute up to 3 person-examinations of data
for analysis.
We also evaluated a dose response by comparing individuals
who consumed 1 soft drink per day and those who consumed over 2 soft
drinks per day with the referent group.
We constructed multivariable models in hierarchical fashion with
adjustment for age and sex (model I)
and for age, sex, physical activity index, smoking, dietary consumption
of saturated fat, trans fat, fiber, magnesium, total calories, and
glycemic index (model II).

We used soft drink consumption data from FFQs at examinations 5 and 6,
which yielded a smaller sample (Figure), to relate the prevalence of
metabolic syndrome across the following categories of intake of regular
versus diet soft drinks using generalized estimating equations:
(1) under 1 diet or regular soft drink per week (referent),
(2) 1 to 6 diet soft drinks per week,
(3) over 1 diet soft drink per day,
(4) 1 to 6 regular soft drinks per week,
(5) 1 to 6 regular or diet soft drinks per week,
and (6) over 1 regular soft drink per day.
Individuals reporting consumption of both diet and regular soft drinks
over 1/d (n = 16) were grouped into the last category empirically.
We evaluated the 2 sets of models (I and II) noted above.

Soft Drink Consumption and Incidence of the Metabolic Syndrome

To assess the relations of soft drink consumption to the incidence of
metabolic syndrome, we excluded participants with prevalent metabolic
syndrome at each of examination cycles 4, 5, and 6 (n = 2,897
person-observations).
Then, we used pooled logistic regression analyses
by combining each 4-year follow-up period of observations to relate the
number of soft drinks consumed per day (examination cola questionnaire)
to the incidence of metabolic syndrome (from examination cycles 4 to 5,
5 to 6, and 6 to 7).23
The eligible participants were free of metabolic syndrome
at each baseline examination,
and in this setting, pooled logistic regression has been shown to
provide risk estimates similar to time-dependent Cox models.24
We compared the consumption of soft drinks over 1 per day with
infrequent drinkers (under 1 per day; referent) and also
tested for a dose response by comparing groups consuming 1 and over 2
soft drinks per day with the referent group.
We evaluated 2 sets of models
(covariates as in models I and II above),
which paralleled the analyses of prevalence of metabolic syndrome.

Consumption of soft drinks varies with age and by sex.25
It has also been suggested that the effects of soft drinks and
carbohydrates on metabolic traits may vary according to age, sex,26
and baseline body weight.27
Therefore, we assessed for effect modification by age (modeled
as a continuous variable), sex, and body mass index
(under 30 versus over 30 kg/m2) by incorporating appropriate interaction
terms in the multivariable models.
We repeated analyses with additionally adjustment
for alcohol consumption and baseline levels of systolic and diastolic
blood pressure, blood glucose, serum triglycerides, and HDL-C.
These models were constructed to account for baseline levels of
metabolic traits.
Additionally, we repeated analyses to examine the association
between consumption of caffeinated and decaffeinated soft drinks,
considered separately, and incidence of the metabolic syndrome.
Because individuals with diabetes mellitus are a particularly high-risk
group for developing metabolic abnormalities, we also repeated our
analyses after excluding those with prevalent diabetes mellitus at baseline.

To compare the risk of new-onset metabolic syndrome according to the
type of soft drink consumed (regular versus diet),
we used data from the FFQs at examinations 5 and 6
and evaluated the incidence of the metabolic syndrome across categories
of soft drinks consumed.
The 6 categories of regular and diet soft drinks were those noted above
(for the analyses of the prevalence of metabolic syndrome),
and 2 sets of models were evaluated
(models I and II, as described above).

Incidence of Individual Components of Metabolic Syndrome

We used multivariable logistic regression to evaluate the relations of
soft drink consumption to the incidence of each individual component of
metabolic syndrome using data from the examination cola questionnaire.
We excluded participants who had the specific metabolic trait prevalent
at baseline; for example, we excluded individuals with blood glucose
over 100 mg/dL (5.5 mmol/L) from the "at-risk" group for analysis that
examined the incidence of impaired fasting glucose.
Thus, we examined the incidence of increased waist circumference,
impaired fasting glucose, high blood pressure, hypertriglyceridemia, and
low HDL-C (all defined as above) according to the number of soft drinks
consumed per day.

We evaluated 2 sets of models (I and II, as noted above) and compared
the risk of developing metabolic traits associated with consumption of
over 1 soft drinks per day
with that in infrequent drinkers (under 1 soft drinks per day).
We also evaluated for a dose response as detailed above.
We did not perform analyses of development of individual metabolic
syndrome components in relation to regular versus diet soft drink intake
using the FFQ data at examinations 5 and 6 because the grouping of
incident events into 6 categories resulted in modest numbers of events
in each category.

All analyses were performed with SAS software version 9.0 (SAS
Institute, Cary, NC). A 2-sided probability value of under 0.05 was
considered statistically significant.

The authors had full access to and take full responsibility for the
integrity of the data. All authors have read and agree to the manuscript
as written.

Results

The baseline characteristics of participants according to the categories
of soft drinks consumed per day are presented in Table 1.

Approximately 35 % of the participants reported consuming over 1 soft
drink per day in response to the examination cola questionnaire
(data based on all 3 examinations).

In comparison, only 22 % of participants reported intake of at least 1
soft drink (diet or regular) per day in response to the FFQ (data
available for examinations 5 and 6 only).

The lower proportion reporting daily intake on the FFQ may be related to
the greater number of options available to indicate soft drink intake;
participants drinking 1 to 6 soft drinks per week (also 22 % on the FFQ)
may have rounded their responses on the examination cola questionnaire
to the nearest integer.

TABLE 1. Baseline Characteristics of Participants According to
Soft Drink Consumption (n = 8997)

In age- and sex-adjusted models, the prevalence of obesity (assessed
both by body mass index and by waist circumference), high blood
pressure, glucose intolerance, low HDL-C, and hypertriglyceridemia was
significantly higher in those who consumed a greater number of soft
drinks per day.

Serum total cholesterol, low-density lipoprotein cholesterol, physical
activity index, and alcohol consumption did not vary across categories
of soft drinks consumed.

Similar trends were obtained when we excluded individuals with prevalent
metabolic syndrome (Data Supplement, Table I).

Prevalence of the Metabolic Syndrome

There was a 48 % higher adjusted prevalence of metabolic syndrome among
those who consumed 1 or more soft drinks per day relative to individuals
with infrequent soft drink consumption (Table 2).

We observed a rising prevalence of metabolic syndrome across categories
of 1 and over 2 soft drinks per day

In parallel analyses with the data from the FFQ (Table 2), participants
who consumed over 1 diet or regular soft drink per day had nearly a
1.8-fold adjusted prevalence of metabolic syndrome compared with
infrequent drinkers (under 1 per week).

TABLE 2. Cross-Sectional Relationships of Soft Drink Consumption With
Prevalence of Metabolic Syndrome

Incidence of the Metabolic Syndrome

Individuals who consumed at least 1 soft drink per day had a 44 % higher
adjusted risk (95 % CI, 20 % to 74 %) of developing metabolic syndrome
compared with infrequent drinkers in multivariable-adjusted analyses
(Table 3).

There was no effect modification by age, body mass index, or sex
(interaction terms were not statistically significant).

After additional adjustment for baseline levels of covariates (blood
sugar, systolic and diastolic blood pressure, triglycerides, and HDL-C)
and alcohol consumption in our models, the association of consumption of
over 1 soft drink per day with incidence of metabolic syndrome remained
robust (odds ratio [OR], 1.44; 95 % CI, 1.19 to 1.74).

Further exclusion of individuals with diabetes mellitus at baseline (n =
138) attenuated the association (OR for over 1 soft drink per day, 1.16;
95% CI 1.00 to 1.34).

After stratification of analyses by caffeinated versus decaffeinated
drinks, results were consistent with the primary analyses; consumption
of over 1 soft drink per day was associated with incident metabolic
syndrome for both types of beverages (Data Supplement, Table II).

TABLE 3. Multiple Logistic Regression Examining Soft Drink Consumption
and Incidence of Metabolic Syndrome (n = 6154)

In analyses with FFQ data (Table 3), intake of at least 1 regular or
diet soft drink per day was associated with a over 50 % higher incidence
of metabolic syndrome than among those who drank under 1 soft drink per
week, although the association was borderline significant for intake of
over 1 regular soft drink per day ( P = 0.07 ).

We also observed a graded increase in the risk of metabolic syndrome
from those who were consuming 1 to 6 diet or regular soft drinks per
week to those who drank over 1 soft drinks per day (diet or regular).

Incidence of Individual Components of the Metabolic Syndrome

Compared with infrequent drinkers, individuals who consumed over 1 soft
drink per day had a 25 % to 32 % higher adjusted risk of incidence of
each individual metabolic trait (Table 4), with the exception of
development of high blood pressure, for which there was a borderline
significant 18 % higher adjusted odds ( P = 0.10).

Discussion

In the present study, we observed a significantly higher prevalence of
metabolic syndrome among middle-aged adults who consumed over 1 soft
drink per day.

This association was consistent for intake of both regular and diet soft
drinks.

Our prospective analyses corroborated the cross-sectional findings;
we observed an increase in the incidence of metabolic syndrome among
adults consuming at least 1 soft drink per day, regardless of whether it
was of the regular or diet type.

Additionally, consumption of soft drinks daily was associated with a
higher incidence of each metabolic syndrome component.

The present study extends results from prior studies that reported that
a greater intake of soft drinks is associated with increased prevalence
of metabolic syndrome, 28 higher risk of obesity, 4–6 high blood
pressure, 7 and diabetes mellitus. 5

The similar metabolic hazard posed by both regular and diet soft drinks
is noteworthy given the lack of calories in the latter; however, other
studies have also reported associations of diet soft drinks with weight
gain in boys 29 and with hypertension in adult women. 7

Mechanisms

There are several mechanisms that can explain the higher risk of
metabolic abnormalities associated with greater consumption of soft drinks.

These can be broadly grouped under physiological effects, dietary
behavior, and the economics of food choice. 13

There are several physiological effects of soft drinks that may pose an
adverse metabolic risk.

Larger consumption of added nutritive sweeteners such as high fructose
corn syrup (the primary sweetener in soft drinks) can lead to weight
gain, increased insulin resistance, 30,31 a lowering of HDL-C, 32 and an
increase in triglyceride levels. 27

Typically, in the United States, the high fructose corn syrup added to
the beverages contains about 55 % fructose. 30,31

Although the association of high fructose corn syrup intake and insulin
resistance may be a contributory mechanism, 31 in the present study,
both regular and diet soft drinks appeared to pose similar metabolic
hazards, which suggests that other factors may be operational.

Consumption of liquids is associated with a lesser degree of dietary
compensation (the adjustment in energy intake made in subsequent meals
in response to food intake).

Some investigators believe that intake of sugar-sweetened beverages
induces less compensation than intake of artificially sweetened soft
drinks, 33 but others disagree. 34

The high sweetness of diet or regular soft drinks may lead to
conditioning for a greater preference for intake of sweetened items, 35
although this explanation also has been questioned by some experts. 13

The caramel content of both regular and diet drinks may be a potential
source of advanced glycation end products, 5 which may promote insulin
resistance 36 and can be proinflammatory. 37

Dietary behavior among individuals consuming soft drinks may account in
part for the clustering of metabolic risk factors in these people. 13

Individuals with greater intake of soft drinks also have a dietary
pattern characterized by greater intake of calories and saturated and
trans fats, lower consumption of fiber 38 and dairy products, 39 and a
sedentary life. 40

These observations were corroborated by the our findings of increased
consumption of saturated and trans fat, lower consumption of dietary
fiber, and higher rates of smoking in those with greater intake of soft
drinks.

Nonetheless, in the present investigation, we adjusted for saturated fat
and trans fat intake, dietary fiber consumption, smoking, and physical
activity in multivariable analyses and still observed a significant
association of soft drink consumption with the risk of developing
metabolic syndrome and its component traits.

It is conceivable, though, that there may be residual confounding caused
by lifestyle factors not adjusted for in the present analyses.

Last, it has been suggested that the obesity-promoting effects of soft
drinks may be related in part to their costs, with less expensive drinks
being associated with greater hazard by virtue of their preferential
selection for economic reasons. 13

The present investigation could not explore this explanation.

Strengths and Limitations

The strengths of the present study include the large community-based
sample of men and women and the adjustments for potential confounders;
however, several limitations merit comment.

We chose to use the modified definition of metabolic syndrome
recommended by the National Cholesterol Education Program 14 and did not
use other criteria for the syndrome (such as those suggested by the
World Health Organization 41 or the European panel).

Researchers have found high correlation between these guidelines. 42

Given the observational nature of the present study, we cannot infer
that the observed associations are causal.

As noted above, it is conceivable that residual confounding by
lifestyle/dietary factors not adjusted for may have contributed to the
metabolic risks associated with soft drink intake.

Finally, participants in the present study were all white Americans,
which may limit the generalizability of our results to nonwhites.

Conclusions

In our large community-based sample of middle-aged adults, soft drink
consumption was associated with higher risk of developing adverse
metabolic traits and the metabolic syndrome.

The present observational data raise the possibility that public health
policy measures to limit the rising consumption of soft drinks in the
community may be associated with a lowering of the burden of metabolic
risk factors in adults.

p 488 CLINICAL PERSPECTIVE

Consumption of soft drinks among children, adolescents, and middle-aged
adults has risen in the United States and Europe during the past 3 decades.

Prior studies have shown a higher prevalence of obesity and diabetes
mellitus in children who consume more soft drinks, although these
associations are less clear for adults.

We evaluated the relations of metabolic syndrome and its components to
soft drink consumption in Framingham participants.

Cross-sectionally, individuals consuming at least 1 soft drink per day
had about 50 % higher prevalence of the metabolic syndrome than those
consuming under 1 drink per day.

During a follow-up period of about 4 years, consumption of over 1 soft
drink per day was associated with a higher incidence of metabolic
syndrome and a higher incidence of each of its components, ie, obesity,
increased waist circumference, impaired fasting glucose, higher blood
pressure, hypertriglyceridemia, and low high-density lipoprotein
cholesterol.

Analyses that used food frequency questionnaire data suggested that
intake of over 1 drink per day of either regular or diet soft drinks was
associated with a over 50% higher incidence of metabolic syndrome
compared with intake of under 1 soft drink per week.

We conclude that consumption of more than 1 soft drink per day is
associated with a higher prevalence and incidence of multiple metabolic
risk factors in middle-aged adults.

Our observational data raise the possibility that public health measures
to limit consumption of soft drinks may be associated with a lowering of
the burden of cardiometabolic risk factors in adults.

" When studying individual classes of caffeinated beverages, habitual
coffee consumption was not associated with increased risk of hypertension.

By contrast, consumption of cola beverages was associated with an
increased risk of hypertension, independent of whether it was sugared or
diet cola (P for trend <.001).

Conclusion
No linear association between caffeine consumption and incident
hypertension was found.

Even though habitual coffee consumption was not associated with an
increased risk of hypertension, consumption of sugared or diet cola was
associated with it.

Further research to elucidate the role of cola beverages in hypertension
is warranted. "

" The findings were consistent between the cohorts and were present
across types of soda beverages:
both sugared cola and diet cola beverages were associated with an
increased risk of hypertension (Table 5 and Table 6).

Hence, we speculate that it is not caffeine but perhaps some other
compound contained in soda-type soft drinks that may be responsible for
the increased risk in hypertension.

If these associations are causal, they may have considerable impact on
public health. "

" Finally, an examination of the possible associations between
caffeinated cola beverages and the risk of hypertension
showed that
sugared caffeinated cola (NHS I, P for trend = .03; NHS II, P for trend
<.001) (Table 5)
and diet caffeinated cola (NHS I, P for trend = .02; NHS II, P for
trend <.001) (Table 6)
were positively associated with hypertension in both cohorts. "

Context
Caffeine acutely increases blood pressure, but the association between
habitual consumption of caffeinated beverages and incident hypertension
is uncertain.

Objective
To examine the association between caffeine intake and incident
hypertension in women.

Design, Setting, and Participants
Prospective cohort study conducted in the Nurses’ Health Studies
(NHSs) I and II of 155,594 US women free from physician-diagnosed
hypertension followed up over 12 years
(1990-1991 to 2002-2003 questionnaires).

Caffeine intake and possible confounders were ascertained from regularly
administered questionnaires.

We also tested the associations with types of caffeinated beverages.

Main Outcome Measure
Incident physician-diagnosed hypertension.

Results
During follow-up, 19.541 incident cases of physician-diagnosed
hypertension were reported in NHS I and 13,536 in NHS II.

In both cohorts, no linear association between caffeine consumption and
risk of incident hypertension was observed after multivariate adjustment
(NHS I, P for trend = .29; NHS II, P for trend = .53).

Using categorical analysis, an inverse U-shaped association between
caffeine consumption and incident hypertension was found.

Compared with participants in the lowest quintile of caffeine
consumption, those in the third quintile had a 13 % and 12 % increased
risk of hypertension, respectively (95 % confidence interval in NHS I, 8
% - 18 %; in NHS II, 6 % - 18 %).

When studying individual classes of caffeinated beverages, habitual
coffee consumption was not associated with increased risk of hypertension.

By contrast, consumption of cola beverages was associated with an
increased risk of hypertension, independent of whether it was sugared or
diet cola (P for trend <.001).

Conclusion
No linear association between caffeine consumption and incident
hypertension was found.

Even though habitual coffee consumption was not associated with an
increased risk of hypertension, consumption of sugared or diet cola was
associated with it.

Further research to elucidate the role of cola beverages in hypertension
is warranted.

INTRODUCTION

Approximately 50 million people in the United States have hypertension,
and the prevalence is increasing. 1

Hypertension is a major risk factor for coronary heart disease, stroke,
and congestive heart failure. 2-3

Therefore, even small reductions in the prevalence of hypertension could
have a potentially large public health and financial impact.

Much clinical lore about the possible association between caffeine
intake and the risk of hypertension is available.

Short-term studies have demonstrated that caffeine intake acutely
increases blood pressure, but over time, attenuation of this effect does
occur. 4

Experimental studies have shown that caffeine can raise plasma levels of
several stress hormones, such as epinephrine, norepinephrine, 5-6 and
cortisol, all of which can lead to an increase in blood pressure. 6-7

However, these experiments have been limited to relatively short
periods of observation, typically less than 1 week; information on a
more sustained neuroendocrine response to regular exposure to caffeine
is not available.

A long-term effect of caffeine intake on the risk of developing
hypertension would be of substantial public health importance given the
widespread consumption of beverages containing caffeine, but currently,
studies of this association are scarce.

A recent longitudinal study in 1,017 men found a positive association
between coffee consumption and blood pressure and incident hypertension
in unadjusted analyses. 8

Although the association with blood pressure level was significant in
multivariate analyses, a nonsignificant 40 % increase in the risk of
incident diagnosis of hypertension (95 % confidence interval [CI], –6 %
to 109 %) for 3 to 4 cups per day and a 43 % increase (95% CI, –6 % to
118 %) for 5 or more cups per day vs no coffee consumption was found.

No published studies to date of the association between caffeine intake
and the risk of hypertension in women are available.

To prospectively elucidate whether caffeine intake or consumption of
certain caffeine-containing beverages is associated with the risk of
incident hypertension in women, we examined these questions in 2 large
cohort studies of women, the Nurses’ Health Studies (NHSs) I and II.

METHODS

Study Populations

The NHS I cohort was assembled in 1976 when 121,700 female registered
nurses, aged 30 to 55 years, completed and returned a mailed
questionnaire. 9

Follow-up questionnaires have been mailed every 2 years to update
information on health-related behaviors and medical events.

The NHS II began in 1989, when 116,671 female registered nurses, aged 25
to 42 years, completed and returned a mailed questionnaire.

Questionnaires have been mailed every 2 years to update exposure
information and diagnosis of new diseases.

The follow-up for both cohorts exceeds 90 %.

In this analysis, all participants who had not been diagnosed with
hypertension before the return of the 1990 NHS I or 1991 NHS II
questionnaires were included.

This study was approved by the institutional review board at Brigham and
Women’s Hospital, Boston, Mass.

Receipt of each questionnaire implies participant’s consent.

Dietary Assessment

Food frequency questionnaires were used to measure dietary intake and
were completed in 1990, 1994, and 1998 for NHS I and 1991, 1995, and
1999 for NHS II.

Participants were asked about their usual intake of foods and beverages
during the past year.

The response options for specified serving sizes were the following:
never or less than once per month;
1 to 3 times per month;
1 per week;
2 to 4 per week;
5 to 6 per week;
1 per day;
2 to 3 per day;
4 to 5 per day;
and 6 or more per day.

The relevant beverages included on the questionnaire were the following:
low-calorie cola (eg, Diet Coke or Diet Pepsi with caffeine),
regular cola (eg, Coke, Pepsi,
or other cola beverages with sugar),
tea with caffeine, tea without caffeine,
coffee with caffeine, and decaffeinated coffee.

Total caffeine intake was calculated primarily using US Department of
Agriculture food composition sources.

In these calculations, it was assumed that the content of caffeine was
137 mg per cup of coffee, 47 mg per cup of tea, 46 mg per can or bottle
of cola beverage, and 7 mg per serving of chocolate candy. 10

This method of measuring coffee intake was shown to be valid in both the
NHS I cohort and a similar cohort study of male health professionals. 11-13

Assessment of Other Variables

Data on height and family history of hypertension were collected at
baseline in both cohorts.

Information on weight was updated every 4 years.

Using each participant’s updated weight, body mass index was calculated
by dividing the weight in kilograms by height in meters squared.

Also, an updated variable for weight difference between baseline and the
time of respective follow-up questionnaire was generated.

Information on oral contraceptive use in the NHS II cohort also was
updated every 4 years.

The same semiquantitative food frequency questionnaires were used to
determine intake of alcohol, sodium, potassium, magnesium, calcium, and
phosphorus. 14

Physical activity was assessed in NHS I (1988, 1992, and 1996) and NHS
II (1989, 1993, and 1997) cohorts; energy expenditure was expressed in
metabolic equivalent tasks. 15

In addition, the frequency of analgesic drug use (aspirin, nonsteroidal
anti-inflammatory drugs, and acetaminophen) was ascertained. 16-17

Outcome Definition

The baseline and biennial follow-up questionnaires inquired about
physician-diagnosed hypertension and the year of diagnosis.

Self-reported diagnosis of hypertension was found to be reliable in the
NHS I cohort. 18

In a subset of women who reported hypertension, review of medical
records confirmed a documented systolic and diastolic blood pressure,
respectively, higher than 140 mm Hg and 90 mm Hg in 100 % and higher
than 160 mm Hg and 95 mm Hg in 77 % of participants.

Additionally, self-reported hypertension was predictive of subsequent
cardiovascular events. 18

A study participant was considered to have a history of hypertension if
she reported a diagnosis of high blood pressure on any questionnaire up
to and including the 1990 questionnaire in NHS I and the 1991
questionnaire in NHS II, and therefore was excluded from the study.

Among the remaining women in each cohort, incident cases were included
as those who first reported hypertension on any of the subsequent
biennial questionnaires and whose date of diagnosis was after the return
of the 1990 NHS I or the 1991 NHS II questionnaire.

This method recently has been used in a study of folate intake and the
risk of hypertension in women. 19

Statistical Methods

The time of observation was between return of the 1990 NHS I and 1991
NHS II and the 2002 NHS I and 2003 NHS II questionnaires.
Participants who did not return the baseline questionnaires for this
study were allowed to contribute person-time for later time intervals,
provided that they had not been diagnosed with hypertension prior to
return of the respective questionnaire.
Participants were censored after being diagnosed with hypertension or at
the time of death.
Each cohort was analyzed separately.
Age-adjusted Cox proportional hazards regression models were used to
estimate relative risks and 95% CIs.
In addition, multivariate models were constructed that adjusted for
other known risk factors of the study outcome:
age (continuous), body mass index (continuous), alcohol use (6
categories), physical activity (quintiles of metabolic equivalent
tasks), smoking status (current, past, or never), family history of
hypertension (yes/no), and current oral contraceptive use (yes/no; only
in NHS II).
In additional analyses, we ensured that sodium, magnesium, calcium,
potassium, and phosphorus intake (quintiles) did not confound the
estimates from these multivariate models.
All variables were updated to reflect the most recent value provided by
the participants on the biennial questionnaires.
Participants with missing data were assigned to a missing category for
that specific time period.
We determined P values for trend for each of the exposures of interest
by using the median for each category.
Level of significance for P values for trend was <.05.
Also the interaction between caffeine intake and the other variables was
tested.
We used SAS version 8.2 for UNIX statistical software package
(SAS Institute Inc, Cary, NC).

RESULTS

In NHS I, 53,175 women had not been diagnosed with hypertension at
baseline in 1990.

Another 7,916 participants who did not respond to the 1990 questionnaire
but who did respond to a later questionnaire disclosing that they
previously had not been diagnosed with hypertension allowed them to
contribute person-time from that point in time.

Over the 12 years (539,388 person-years of follow-up), 19,541 incident
cases of physician-diagnosed hypertension were reported.

In NHS II, 94,503 participants who were free of hypertension (87,369 in
1991 and an additional 7,134 at a later point in time) were included in
the analyses of younger women.

During 909,199 person-years of observation, 13,536 participants
responded that they were diagnosed with hypertension by a physician.

Participant characteristics by quintile of caffeine intake are presented
in Table 1.

In both cohorts, mean caffeine consumption ranged from less than 20 mg/d
in the lowest quintile to approximately 600 mg/d in the highest quintile.

Caffeine intake was correlated positively with alcohol consumption and
smoking status
r = 0.12, P < .001 for NHS I; r = 0.23, P < .001 for NHS II),
whereas all other relevant characteristics did not differ
materially across quintiles of caffeine consumption.


Table 1. Baseline Characteristics of Cohort by Quintile of Caffeine
Intake in Nurses’ Health Study I (N = 53,175)
and Nurses’ Health Study II (N = 87,369)*

Age-adjusted analyses demonstrated an inverse U-shaped relation between
caffeine intake and the incidence of hypertension in both cohorts.

Compared with participants in the lowest quintile of caffeine
consumption, the risk of incident hypertension was increased by 14 % (95
% CI, 9 % -19 % for NHS I) and 15 % (95 % CI, 9 % - 21 % for NHS II) for
those in the third quintile, whereas those in the highest quintile were
not at an increased risk of hypertension (Table 2).

Multivariate adjustment did not materially change these findings (Table 2).

Table 2. Age-Adjusted and Multivariate Relative Risks for Incident
Hypertension According to Quintile of Caffeine Intake

To further examine this inverse U-shaped association, the frequency of
use of different caffeine-containing beverages in relation to the risk
of incident hypertension was evaluated.
In multivariate models including beverage type, rather than actual
caffeine intake, no association between frequency of intake of
caffeinated coffee and incident hypertension was observed in either cohort.
Compared with NHS I participants drinking less than 1 cup per day of
caffeinated coffee, the relative risks were
1.06 (95% CI, 1.01-1.10) for those consuming 1 cup per day,
1.00 (95% CI, 0.97-1.04) for those drinking 2 to 3 cups per day,
0.93 (95% CI, 0.88-0.99) for those drinking 4 to 5 cups per day,
and 0.88 (95% CI, 0.80-0.98) for those drinking 6 or more cups per day
(Table 3).
The trend for the NHS I cohort was marginally significant for
an inverse association between coffee intake and the risk of
hypertension (Table 3; P for trend = .02).
The findings in the NHS II cohort were practically identical (P for
trend = .03).
The results for intake of decaffeinated coffee also were similar to the
data for caffeinated coffee intake (data not shown);
the trend suggested an inverse association of risk of hypertension in
the NHS I cohort (P for trend = .08)
but not in the NHS II cohort (P for trend = .67).

Table 3. Age-Adjusted and Multivariate Relative Risks for Incident
Hypertension According to Frequency of Coffee Intake

An association between caffeinated tea intake and incident hypertension
in the NHS I cohort (Table 4; P for trend = .79) was not found.
However, in the cohort of younger women in NHS II, a moderate increase
in risk of hypertension (P for trend = .01; Table 4) was detected.

Table 4. Age-Adjusted and Multivariate Relative Risks for Incident
Hypertension According to Frequency of Caffeinated Tea Intake

Finally, an examination of the possible associations between caffeinated
cola beverages and the risk of hypertension
showed that
sugared caffeinated cola (NHS I, P for trend = .03; NHS II, P for trend
<.001) (Table 5)
and diet caffeinated cola (NHS I, P for trend = .02; NHS II, P for
trend <.001) (Table 6)
were positively associated with hypertension in both cohorts.

Additional analyses adjusting for intake of sodium, magnesium,
potassium, phosphorus, and calcium or analgesic drug use did not change
the results materially for the caffeine intake or specific beverage
intake analyses. When testing the robustness of the results, such as by
limiting the analysis to those women who reported having had a routine
physical examination during the time interval or by using baseline body
mass index and updated change in weight rather than updated body mass
index, the results were virtually unchanged (data not shown).

COMMENT

In this prospective study of the association between caffeine intake and
the risk of physician-diagnosed hypertension in 2 large cohorts of
women, we found a modest inverse U-shaped association between caffeine
intake and hypertension in both cohorts.

The magnitude of the highest multivariate relative risk was 1.13 in NHS
I and 1.12 in NHS II.

To better understand this nonlinear relation between caffeine intake and
the risk of hypertension, we evaluated the individual associations of
several caffeine-containing beverages.

Neither caffeinated nor decaffeinated coffee demonstrated a positive
association with incident hypertension in either cohort.

The results for consumption of caffeinated tea were inconclusive:
although no association was observed in the NHS I cohort, a positive
trend was shown in the NHS II cohort.

By contrast, we found a highly significant association between cola
intake (sugared or low-calorie cola) and incident hypertension that was
consistent across the cohorts.

To our knowledge, this study is the first to prospectively evaluate the
putative effect of caffeine consumption on the long-term risk of
hypertension in women.

The speculation that coffee may cause hypertension was supported by
several small experiments over short periods of observation ( under 80
days). 20

If the short-term effects of caffeine on blood pressure persist, then
habitual coffee drinking might contribute to an excess risk of hypertension.

Such an effect would be of great public health importance given the
widespread use of coffee and other caffeinated beverages.

In this study with more than 1.4 million person-years of follow-up, the
relevant exposures and outcomes have been found valid and accurate,
11-13,18 and coffee intake was updated to reflect changes in individual
behavior.

We found strong evidence to refute speculation that coffee consumption
is associated with an increased risk of hypertension in women.

The associations found between caffeinated tea consumption and the risk
of hypertension differed between the 2 cohorts.

In the NHS I cohort, no association was found; however, in the NHS II
cohort, a significant positive trend was observed.

A recent study conducted among 711 men and 796 women in Taiwan found a
strong inverse association between both frequency and duration of tea
intake and hypertension. 21

Since the types of tea (green or oolong) consumed in that study are
likely different from those consumed in our study of US women, the
comparability of the findings from these 2 studies appears uncertain.

In both NHS cohorts we found a positive association between frequency of
caffeinated soft drink consumption and the risk of hypertension.

The findings were consistent between the cohorts and were present across
types of soda beverages: both sugared cola and diet cola beverages were
associated with an increased risk of hypertension (Table 5 and Table 6).

Hence, we speculate that it is not caffeine but perhaps some other
compound contained in soda-type soft drinks that may be responsible for
the increased risk in hypertension.

If these associations are causal, they may have considerable impact on
public health.

Recent studies have found an effect of the intake of cola beverages on
insulin resistance in a rat model 22; in humans, the intake of cola
beverages was associated with an increased risk of diabetes in the NHS
II cohort. 23

These studies have attributed these associations to the glycemic load of
corn syrup, which is used as sweetener in these beverages, and the
caramel coloring, which is rich in advanced glycation end products.

Further studies on the possible mechanisms underlying these associations
clearly are needed.

We acknowledge the limitations of this study.

We cannot rule out that individuals susceptible to adverse effects of
caffeinated coffee intake on their blood pressure in the past may have
reduced their consumption of beverages containing caffeine.

Patients were asked about the frequency of their food intake, but no
information was available on the daily timing of such ingestion.

We did not directly measure the participants’ blood pressure and the
diagnosis of hypertension was self-reported.

Nonetheless, self-reported blood pressure has been validated and
demonstrated to be a strong predictor of actual values. 18

Furthermore, we do not know whether these findings are generalizable
beyond populations of predominantly white women.

We also cannot exclude the possibility that the associations found are
residually confounded.

Lastly, no statement can be made on the effect of coffee intake on the
control of blood pressure among individuals already diagnosed with
hypertension.

In conclusion, consumption of coffee in women does not appear to
increase the risk of developing hypertension.

Whether caffeinated soft drinks are causally related to the risk of
hypertension and its underlying mechanism will require further study.

" Our finding that drinking diet soda during the past year was
associated with weight gain in boys was somewhat unexpected,
particularly because a recent double-blind randomized controlled trial
of overweight adults compared the effects of sucrose and artificial
sweeteners (primarily in beverages) and demonstrated weight loss for the
latter group (71).

However, our overweight boys were drinking nearly 3 times as much diet
soda as our normal weight boys (0.3 vs. 0.1 servings/d)
but similar quantities of regular soda (0.6 servings/d for both groups).

The correlation between year-to-year changes in regular soda and diet
soda intakes was null (r = –0.008; p = 0.70),
suggesting that heavier boys were not substituting diet soda for sugared
soda.

We believe that this explains the diet soda estimate for boys and,
furthermore, illustrates the importance of confirming findings using
blinded randomized trials whenever feasible and ethical.

Because our estimates became considerably smaller after adjusting for
total energy intake, calories probably explain the associations between
beverages and weight gain.

However, we cannot differentiate between calories in the beverages and
calories in foods typically consumed alongside certain beverages (46),
or whether drinking beverages leads to higher subsequent energy intakes
because compensation for energy consumed in liquid form is less complete
than energy consumed in solid form (45) (47) (48). "

Objective:
The increase in consumption of sugar-added beverages over recent decades
may be partly responsible for the obesity epidemic among U.S. adolescents.

Our aim was to evaluate the relationship between BMI changes and intakes
of sugar-added beverages, milk, fruit juices, and diet soda.

Research Methods and Procedures:

Our prospective cohort study included >10,000 boys and girls
participating in the U.S. Growing Up Today Study.

The participants were 9 to 14 years old in 1996 and completed
questionnaires in 1996, 1997, and 1998.

We analyzed change in BMI (kilograms per meter squared) over two 1-year
periods among children who completed annual food frequency
questionnaires assessing typical past year intakes.

We studied beverage intakes during the year corresponding to each BMI
change, and in separate models, we studied 1-year changes in beverage
intakes, adjusting for prior year intakes.

Models included all beverages simultaneously; further models adjusted
for total energy intake.

Results:
Consumption of sugar-added beverages was associated with small BMI gains
during the corresponding year
(boys: +0.03 kg/m2 per daily serving, p = 0.04;
girls: +0.02 kg/m2, p = 0.096).

In models not assuming a linear dose-response trend,
girls who drank 1 serving/d of sugar-added beverages gained more weight
(+0.068, p = 0.02) than girls drinking none,
as did girls drinking 2 servings/d (+0.09, p = 0.06)
or 3+ servings/d (+0.08, p = 0.06).

Analyses of year-to-year change in beverage intakes provided generally
similar findings;
boys who increased consumption of sugar-added beverages from the prior
year experienced weight gain (+0.04 kg/m2 per additional daily serving,
p = 0.01).

Children who increased intakes by 2 or more servings/d from the prior
year gained weight (boys: +0.14, p = 0.01; girls +0.10, p = 0.046).

Further adjusting our models for total energy intake substantially
reduced the estimated effects, which were no longer significant.

Discussion:
Consumption of sugar-added beverages may contribute to weight gain among
adolescents, probably due to their contribution to total energy intake,
because adjustment for calories greatly attenuated the estimated
associations.

Introduction

Large increases over recent decades in the prevalence of childhood
obesity are well documented (1) (2) (3) (4) (5) (6) (7) (8) (9), as are
the associated health and social consequences of obesity (3) (7) (8) (9)
(10) (11) (12) (13) (14) (15) (16) (17) (18) (19) (20) (21) (22) (23)
(24) (25) (26) (27) (28) (29).

This rapid increase in obesity prevalence implicates environmental
factors (27) (30) (31) (32) (33) (34) (35).

During this time, physical activity among adolescents has declined,
whereas time spent in sedentary activities such as watching
television or videos and playing computer games has increased (5) (6).

Furthermore, in nationally representative samples of U.S. adolescents,
intakes of sugar-added beverages, including soda, have increased (36)
(37) (38) (39).

Higher soft drink intakes are associated with lower milk and fruit juice
intakes and with higher total energy intakes (40).

The largest source of added sugars in the U.S. diet is nondiet soft
drinks (37)

One cross-sectional study of dietary intakes (41) has reported similar
soda and fruit drink intakes for obese vs. nonobese adolescents,
whereas another has found a positive correlation between measures of
adiposity in adolescents and soft drink intakes (42).

However, two other studies have suggested an inverse association between
adiposity and intake of sugars (43) (44).

Ludwig et al. (45) published the first longitudinal analysis of
sugar-added beverage intakes and body weight changes.
They followed 548 ethnically diverse 11- and 12-year-old children in
Boston-area public schools for 19 months and found positive associations
among sugar-sweetened beverage intakes, weight change, and incident obesity.
Whether the critical factor is the sugar, the calories, or behaviors
related to beverage consumption is unknown.
Aside from the calories within each beverage, some foods may frequently
accompany certain beverages (46), and drinking beverages may also lead
to higher subsequent energy intakes because compensation for energy
consumed in liquid form is less complete, due to lower satiety, than
energy consumed in solid form (45) (47) (48).
Furthermore, sugar-added beverages may encourage additional energy
intake because of their high glycemic index (49).
It may be informative to further consider all beverages simultaneously
and to study children from a broader age range and with longer follow-up.

Using data from the Growing Up Today Study, an ongoing prospective
cohort study of children from all over the U.S., we analyzed the
relationship between intakes of beverages
(milk, sugar-added beverages, fruit juices, and diet soda)
and changes over time in BMI.

Research Methods and Procedures

Study Population

Established in the fall of 1996, the Growing Up Today Study consists of
16,771 children, residing in 50 states, who are offspring of Nurses’
Health Study II (NHSII)1 participants (50).

The study is described in detail elsewhere (51).

These children were ages 9 through 14 years old in 1996.

In 1997 and 1998, we sent subjects follow-up questionnaires to update
all information.

Response rates to at least one of these follow-ups were 92.5% for girls
and 87.7% for boys.

Measurements

BMI.

Children self-reported their height and weight annually on our
questionnaire, which provided specific measuring instructions but
suggested that they ask someone for help.
Because their mothers are nurses who biennially self-report their own
height and weight as part of NHSII, assistance was available to each of
them.
A previous study reported high validity for self-reported heights and
weights for children 12 to 16 years old (52).
We assessed adiposity by computing BMI = weight/(height)2 squared
(kilograms per meter squared).
The International Obesity Task Force supports the use of BMI to assess
fatness in children and adolescents (53).
Childhood BMI is related to other measures of adiposity that were not
feasible to include in our large self-report study (54) (55).
A recent study (56) supports the validity of BMI computed from
self-reported height and weight, with a correlation of 0.92 between BMI
computed from measured values and self-reports by youth in grades 7
through 12.

Before computing BMIs, we excluded any height that was >3 SD beyond the
gender-age-specific mean height (0.46% of heights excluded) and any
1-year height change which declined by >1 inch or increased by >3 SD
above the mean change (1.65% excluded).
We further excluded any BMI < 12.0 kg/m2 as a biological lower limit
(clinical opinion, MWG) and BMI > 3 SD above or below the
gender-age-specific mean [log(BMI) scale] (0.87% excluded).
We then estimated our outcome, annual change in adiposity, by
BMI1997 – BMI1996 and BMI1998 – BMI1997, dividing each by the exact time
interval between the pair of measurements.
Because all these represented realistic 1-year changes in weight, there
were no further BMI exclusions: 6,871 girls and 5,321 boys provided BMI
change data.
Unfortunately, no validation studies of change in BMI, derived from
self-reported data, have been conducted.

We grouped children, based on their BMI at the earlier year of each
1-year time interval, using the Centers for Disease Control and
Prevention (CDC) gender- and age-specific percentiles for BMI (57) .
Children above the 85th percentile were at risk of overweight (85th to
95th percentile), and those above the 95th percentile were overweight
(57).
Similarly, we grouped together those below the 10th percentile
for BMI.
For simplicity, we refer to all children whose BMI exceeded the
85th percentile as "overweight," those below the 10th percentile as
"very lean," and those between the 10th and 85th percentiles as "normal
weight."
The CDC standards were also used to assign age-specific z scores to BMIs.

Beverages.

Members of our research group designed a self-administered
semiquantitative food frequency questionnaire (FFQ), specifically for
older children and adolescents, which is inexpensive and simple to
administer to large populations (58).

This FFQ for youth has been shown to be valid and reproducible on
children 9 through 18 years old (58) (59);
the mean correlation for nutrients from the FFQ compared with three
24-hour recalls was r = 0.54,
which is comparable with the performance of a similar adult FFQ.

The youth FFQ included questions regarding frequency of intake of 132
specific food items over the past year.

Beverage questions indicated that the serving size was a can, glass,
bottle, or cup (tailored to the particular beverage).

The question about "Hawaiian Punch, lemonade, Koolaid, or other
noncarbonated fruit drink" preceded questions about "orange juice" and
"apple juice and other fruit juices."

For each beverage, we derived typical past year intake (servings per
day) and change in intakes between years.

We also estimated total energy intake (kilocalories per day) and
excluded as implausible intakes <500 or >5000 kcal/d (0.53% excluded).

The beverages we studied were
sugar-added beverages (soda, sweetened iced tea, and noncarbonated fruit
drinks), fruit juices (orange juice and apple/other juices), diet soda,
and milk (white, in a glass or on cereal, and chocolate).

Alcohol and coffee intakes were very low;
therefore, we did not include them.

Physical Activity.

We developed a physical activity questionnaire, specifically for youth,
which asked the participants to recall the typical amount of time spent,
within each season over the past year, in 17 activities and team sports
(outside of gym class); response categories ranged from 0 to 10+ h/wk.
From each child’s responses, we computed his/her typical hours of
weekly physical activity within each season and over the entire year.
Assessments of an earlier nonseasonal version of this instrument found
that estimates of total physical activity were moderately reproducible
and reasonably correlated with cardio-respiratory fitness, thus
providing evidence of validity (60).
Another validation study reported a correlation of r = 0.80 between
survey self-reports and 24-hour recalls in sixth to eighth grade
children (61).
We developed the seasonal version used in this paper to further improve
reliability and validity (62).
Estimates of total physical activity that exceeded 40 h/wk were deemed
implausible and excluded (3.8%).

Inactivity.

Another series of questions was designed to measure weekly hours of
recreational inactivity: "watching TV," "watching videos or VCR," and
"Nintendo/Sega/computer games (not homework)."
For each of these, children reported their usual number of total hours,
separate for weekdays and for weekends, from options ranging from 0 to
31+ hours.
From this information, we computed each child’s typical hours of
recreational inactivity per week.
Gortmaker and colleagues (61) reported moderate reproducibility for
children in grades six to eight for recalled total inactivity from a
similar instrument.
We considered totals exceeding 80 h/wk implausible and excluded them
(0.94%).

Race/Ethnicity.

At baseline, children reported their race/ethnic group by marking all of
six options that applied.
We assigned each child to one of five racial/ethnic groups following
U.S. Census definitions, except that we retained Asians as a separate
group rather than pooled with "other" (1).

Tanner Stage, Menarche, and Age.

Each year, children reported their Tanner maturation stage, a validated
self-rating (63) of sexual maturity that uses five
categories/illustrations for stage of pubic hair development,
and girls reported whether/when their menstrual periods began.
We derived a menstrual history variable having three categories:
premenarche both before and after the 1-year BMI change,
periods that began during the interval,
and postmenarche both years.
We computed each child’s age from dates of birth and questionnaire return.

Statistical Analyses

To assess the potential for selection bias, we compared the baseline
(1996) values of age, BMI, individual beverage intakes, and total energy
intakes of those children who returned surveys in consecutive follow-up
years with those who did not.
The differences were small (see "Results").
All models throughout were fit separately for boys and girls.

Cross-Sectional Analyses.

We reported gender- and age-specific means at baseline for height,
weight, total energy intake, and daily intakes of seven beverages.
A linear regression model related baseline total daily energy intakes to
the intake of each beverage.

Longitudinal Analyses.

To study the effects of beverage intakes during the year of BMI change,
we related the past year typical beverage intakes reported in 1997 to
change in BMI from 1996 to 1997 and intakes reported in 1998 to BMI
change from 1997 to 1998.
Because each child can have two BMI changes,
the assumption of independent observations required by ordinary
regression models was not met, so we used mixed linear regression models
(64) with estimation by SAS proc mixed (65).

We also estimated the effects of 1-year change in beverage intakes (the
difference between intakes in 1996 and 1997 and between 1997 and 1998)
on same-year change in BMI.
The prior year intake (reported in 1996 and 1997) was included as a
covariate in the mixed model.

All models adjusted for race/ethnicity, and to account for increases in
BMI that typically occur during growth and maturation, we included
height growth during the same year, menstrual history, Tanner stage,
prior BMI z score, and nonlinear age trends (30) (66) (67) (68) (69)
(70).
Models also adjusted for activity and inactivity during the year
of BMI change (51) and for milk type (whole/2%/1%/nonfat/soy).
We included total energy intake in further models as a hypothesized
intermediary in the pathway between beverages and weight gain.

Results

These children, whose mothers are all participants in the NHSII (50),
are mostly white (94.7%).

At baseline, 23.2% of the boys and 17.5% of the girls were overweight
(>85th percentile on CDC BMI charts),
whereas 7.2% of the boys and 8.6% of the girls were very lean (<10th
percentile).

Children who did not return surveys in adjacent years (required for
inclusion in our longitudinal analyses) were slightly older (girls by
0.20 years; boys by 0.32 years; both p < 0.05).
At baseline, they drank slightly less milk (girls by 0.18 servings/d;
boys by 0.11 servings/d)
but more sugar-added beverages
(girls by 0.13 servings/d; boys by 0.10 servings/d)
(each age-adjusted p < 0.05).
There were no significant differences at baseline in age-adjusted BMI,
total energy intake, fruit juice intake,
or diet soda intake (each age-adjusted p > 0.05).

Cross-Sectional Results

Older children drank less milk but more orange juice, soda, iced tea,
and punch than younger children (Table 1).

Boys reported higher energy intakes and drank more milk, punch, orange
juice, and soda than did same-age girls.

At baseline, children who drank more milk and less diet soda were leaner,
whereas girls who drank more sugar-added beverages were heavier
(BMI +0.06 kg/m2 higher per serving, p = 0.04).

Table 1. Baseline means for total energy intakes (kilocalories
per day), beverage intakes (servings per day), height (inches), and
weight (pounds) for youth participating in the Growing Up Today Study

To explore whether drinking certain beverages may be linked to higher
total energy intakes, we related daily total energy intake to each of
the beverages separately (Table 2) .

As expected, diet soda intakes were not associated with higher total
energy intakes.

Milk intakes were associated with total energy intakes, with per serving
effects slightly more than the energy provided by the milk, whereas the
per serving effects for sugar-added beverage and fruit juice intakes
were considerably larger than their own energy contents.

Table 2. Cross-sectional association between beverage intakes and
total energy intakes at baseline*

Longitudinal Results

Among children who completed the FFQ all 3 years, mean milk intake
declined significantly each year,
whereas soda intake increased significantly (Figure 1).

Apple juice intake declined for both boys and girls between 1996 and 1997,
diet soda and orange juice intake each increased for girls between 1997
and 1998,
and orange juice intake increased for boys each year (all p < 0.05).

Figure 1. Mean beverage intakes in children from the Growing Up
Today Study who provided dietary data in all 3 years of follow-up. All
year-to-year increases in soda intake and declines in milk intake were
statistically significant.

Beverage Intakes During Year of BMI Change.

We related BMI changes over 1-year periods to beverage intakes during
the same year. The regression coefficients ß (Table 3) represent the
1-year change in BMI (kilograms per meter squared) expected per usual
daily serving of each beverage.

For boys, intakes of sugar-added beverages (ß = 0.03)
and diet soda (ß = 0.12) were significantly associated with weight gains;
there were suggestions (p < 0.06) that intakes of milk (ß = 0.02)
and fruit juices (ß = 0.04) were also associated.

After including total energy intake in the model, the estimated ßs for
all beverages (except diet soda) were nearly one-half their unadjusted
magnitudes and no longer significant (p > 0.31; Table 3 ).

For girls, our analysis suggested (p < 0.10) a linear association
between 1-year weight gain and intakes of milk (ß = 0.02) and
sugar-added beverages (ß = 0.02); the corresponding energy-adjusted
estimates were slightly smaller (all p > 0.15; Table 3 ).

Table 3. Longitudinal analysis of beverage intakes and change in
BMI (kilograms per meter squared) during the same time period*

Figure 2 (far left) presents the association between BMI change and
sugar-added beverages analyzed as a categorical variable (0, 1, 2, or 3+
servings/d) to permit nonlinear trends; all Figure 2 models adjusted for
all covariates except energy intake. A dose-response trend was confirmed
for boys, consistent with the statistically significant per-serving
effect (also shown in Figure 2 ). Girls who reported one (0.5 to 1.5)
daily serving of sugar-added beverages gained significantly more BMI
(0.068 kg/m2, p = 0.02) during the year than those reporting none (0 to
<0.5 servings) (Figure 2 , far left). Girls consuming two (+0.09, p =
0.06) or three+ servings (+0.08, p = 0.06) also gained weight compared
with nondrinkers.

intake (left) or 1-year change in intake (right), and 1-year change in
BMI. Estimates are shown separately for number of servings per day
compared with none and for the per-serving effect (assumes a linear
dose-response trend). Models adjusted for all covariates except energy
intake.

Beverage Change and BMI Change.

For boys, increasing sugar-added beverage intake from one year to the
next was significantly associated
(ß = 0.04 per added daily serving; p = 0.01)
with weight gain (Table 4),
and increasing milk and diet soda intakes
were weakly associated (p < 0.10) with weight gain.
With total energy intake (prior year energy and change in energy) in the
model, estimates for the energy-containing beverages each declined by
>40%, and none remained significant (Table 4).
For girls, increasing intake of sugar-added beverages was weakly
linearly related to weight gain
(ß = 0.03, p = 0.08); energy adjustment diminished the estimated effect
(p = 0.16).

Table 4. Longitudinal analysis of change in beverage intakes and
change in BMI (kilograms per meter squared) over the same year,
adjusting for prior beverage intakes*

Figure 2 (right half) shows that boys who increased their sugar-added
beverage intake by 1 serving/d from the previous year gained more weight
(+0.10 kg/m2, p = 0.02) than boys with unchanged intake, and those who
increased their intake by 2 or more servings/d gained even more (+0.14,
p = 0.01).
Girls (Figure 2 , right) who increased their intake by 1 serving/d over
the previous year gained marginally more BMI (+0.065, p = 0.079)
than girls whose intakes were unchanged, and girls whose intakes
increased by 2 or more servings/d
gained significantly more BMI (+0.10, p = 0.046).

Combining Energy-Containing Beverages.

Because the models in Tables 3 and 4 suggested that any of the beverages
containing calories might contribute to male weight gains, we combined
together these beverages (total servings per day of milk, sugar-added
beverages, and fruit juices).
For boys, this total was associated with weight gain
(ß = +0.03 kg/m2 per daily serving during the year of BMI change, p = <0.01;
and ß = +0.03 per increase in daily serving from the prior year, p =
<0.01).
For girls, because the ßs for fruit juice were <0 in Tables 3 and 4,
combining fruit juice intakes with milk and sugar-added beverages
did not provide a significant association
(ß = +0.01, p = 0.096 per daily serving during the year of BMI change;
and ß = +0.01, p = 0.13 per increase in daily serving from the prior year).
After energy adjustment, significant effects became smaller by at least
31% and were no longer significant (p > 0.12).

Discussion

Although a previous publication (45) considered whether sugar-added
beverages contribute to weight gain among 11- to 12-year-old children,
we addressed the effects of several types of beverages on children 9 to
17 years old.

Our strongest and most consistent evidence was a linear association
between sugar-added beverage intakes (past year and change from prior
year) and weight gain in boys (both p < 0.05).

The evidence for girls was less compelling but still suggestive (p <
0.10) of a linear association between sugar-added beverages and weight gain.

Girls who drank 1 serving/d during the past year gained more weight than
nondrinkers (p < 0.05).

Both boys and girls who increased their intakes by 2 or more servings/d
from the previous year experienced significant weight gain, as did boys
who increased their intakes by 1 serving/d from the previous year.

However, the magnitudes of these estimated effects were small;
a boy consuming 3 servings/d of sugar-added beverages over
10 years is expected to gain only 0.9 BMI more than if he consumed none.

Our finding that drinking diet soda during the past year was associated
with weight gain in boys was somewhat unexpected,
particularly because a recent double-blind randomized controlled trial
of overweight adults compared the effects of sucrose and artificial
sweeteners (primarily in beverages) and demonstrated weight loss for the
latter group (71).

However, our overweight boys were drinking nearly 3 times as much diet
soda as our normal weight boys (0.3 vs. 0.1 servings/d)
but similar quantities of regular soda (0.6 servings/d for both groups).

The correlation between year-to-year changes in regular soda and diet
soda intakes was null (r = –0.008; p = 0.70),
suggesting that heavier boys were not substituting diet soda for sugared
soda.

We believe that this explains the diet soda estimate for boys and,
furthermore, illustrates the importance of confirming findings using
blinded randomized trials whenever feasible and ethical.

Because our estimates became considerably smaller after adjusting for
total energy intake, calories probably explain the associations between
beverages and weight gain.

However, we cannot differentiate between calories in the beverages and
calories in foods typically consumed alongside certain beverages (46),
or whether drinking beverages leads to higher subsequent energy intakes
because compensation for energy consumed in liquid form is less complete
than energy consumed in solid form (45) (47) (48).

The compensation theory that liquid foods have lower satiety than solid
foods would apply to milk and fruit juice as well as to sugar-added
beverages.

Sugar-added beverages may also encourage further energy intake because
of their high glycemic index (49).

Under any of these possible mechanisms, consumption of sugar-added
beverages encourages higher total energy intakes, which promotes weight
gain, so that adjusting models for energy should diminish the estimated
associations.

The fact that sugar-added beverages lost statistical significance in
energy-adjusted models does not imply that sugar-added beverages are not
responsible for weight gain because of the pathway.

The literature regarding cross-sectional associations between adiposity
and beverage consumption is mixed (41) (42) (43) (44) (72).

Our cross-sectional results indicated that heavier children were
drinking less milk and more diet soda, presumably to lose weight or
prevent further weight gain, although girls who drank sugar-added
beverages tended to be heavier.

In a nationally representative sample of U.S. children, BMI was
positively associated with diet carbonated beverages and, for girls,
negatively associated with milk intakes (70).

We further presented cross-sectional evidence similar to Harnack et al.
(40) that drinking sugar-added beverages was associated with higher
total energy intakes.

The first longitudinal study of sugar-sweetened beverages (45), on 548
ethnically diverse 11- and 12-year-old children in Boston-area public
schools, reported associations between change in beverage intakes from
baseline to 19 months later and BMI change.

Their study differed from ours in that they did not have Tanner Stage
data, their FFQ and report of activity/inactivity related to past month
(ours was past year), and they did not study milk intakes.
Their BMIs were measured rather than self-reported, which may partially
explain why their estimate for a single serving per day increase
[ß = +0.20 kg/m2 over 19 months, not energy adjusted; from their Table 2
(45) ] is larger than our estimate
(over 12 months: boys ß = +0.10 kg/m2, p = 0.02; girls +0.07, p = 0.08).

A major strength of our analysis was the longitudinal design, which
allowed us to study changes over time in beverage intakes and in BMI
while accounting for growth and maturation.

BMI typically goes up from year to year among children in this age
range, and we took these changes into account.

Although our observational study cannot provide conclusive evidence of
causality, our evidence is stronger than that obtainable from
cross-sectional studies.

Baseline differences between children excluded and included in our
longitudinal analyses were small, though the loss of some children with
higher intakes of sugar-added beverages (0.1 more servings/d)
could bias our estimates of those effects.

Because we included all beverages together in our models, we minimized
confounding by other beverage intakes.
However, residual and unmeasured confounding is still possible despite
extensive control for many important covariates.
A major limitation of our study was the necessity of collecting data
(including height, weight, and beverage intakes by FFQ) on youth by
self-report on mailed questionnaires, but with our large geographically
dispersed cohort, alternatives were not feasible.
The impact of random reporting errors should be to bias estimates of
true associations toward the null, possibly explaining why our estimates
were quite small even when statistically significant.
Large soft drink portion sizes complicate the reporting of intakes and
encourage overconsumption (35).
Data collected by 24-hour recalls from 1994 to 1996 (73) showed that
the average soft drink portion size was 19.9 ounces, and differences
were noted among eating locations (home, restaurant, and fast food).
Our FFQ did suggest portion sizes ["soda, not diet (1 can or glass)";
response category "1 can per day"] but did not specify the number of
ounces in a can or glass, so confusion over this may have further
biased our estimates toward the null.

Although we cannot claim that our children of nurses are representative
of U.S. children, the associations among factors within our cohort
should still be internally valid.
Our sugar-added beverage intakes for 11- to 12-year-old children (1.35
servings/d for boys and 1.14 for girls) were similar to those of 11- to
12-year-old children studied by Ludwig et al. (1.22 servings/d) (45).

In 1998, Jacobson summarized the history of soft drink consumption, its
nutritional value, its potential impact on osteoporosis, tooth decay,
heart disease, and kidney stones, and its marketing by the industry,
with recommendations for what should be done (74).

Here, we extend the evidence (45) that sugar-added beverages (which
include soda) may contribute to weight gain.
Even if milk and fruit juice also contribute to weight gain, they have
nutritional benefits, whereas soda provides only calories (74).
The increase in soft drink serving sizes and the increase in energy
intakes provided by soft drinks since 1977 have been documented (73)
(75) (76) , and reversing this trend may help prevent further increases
in obesity prevalence.

For both children and adults, prevention of obesity is critical, and for
weight loss, recommendations include eating a nutritionally balanced,
low-energy diet while increasing energy expenditure through regular
physical exercise (77) (78).
Beverage intakes, including limiting the consumption of soft drinks, are
a potential target for improving diets of adolescents (42) (45) (74) (79).
Data from our cohort suggested that children who reduce intakes of
sugar-added beverages, along with other behavior modifications such as
increasing physical activity and reducing time with TV/videos/computer
games (80) , may prevent excessive weight gains that can lead to obesity.

13 mainstream research studies in 24 months showing aspartame toxicity,
also 3 relevant studies on methanol and formaldehyde: Murray 2007.11.14

Aspartame toxicity was shown in thirteen detailed mainstream research
studies in 24 months in work by expert teams in USA, South Africa,
England, Italy, Greece, Hungary, and Mexico.

Very little has been publicized in mass print and broadcast media.

Also highly relevant are a study in South Korea that finds levels of
methanol similar to those from aspartame drinks cause the hangovers
from alcohol drinks, a study in China on Alzheimer's type damage in
nerve cells from low dose formaldehyde, and an IARC review by 25
experts that determines formaldehyde to be a human carcinogen.

Table 1. NIH-AARP Diet and Health Study aspartame intake levels from

cohort %
46 ------- 25 ------ 13 ------ 7 -------- 5 -- about 3 --- under 1


This is the first good data about the percentage of aspartame users
who use over 3 cans daily, averaging 5 cans daily at 200 mg per 12 oz
can diet soda.

About 4 % of 473,984 is 19,000 people, with a peak intake of 17 cans
daily, and average 5 cans daily.

It would be worthwhile to investigate a wide variety of symptoms for
the 0.1 % of highest level users, about 500 people.

For about 200 million USA aspartame users, this would be 200,000
people.

Table 1 reveals consistent increase in problems from

--------------------- zero to (400-600) to (over 600) mg/d
aspartame intake:

Calories kcal ----- 1,919 ---- 1,855 ---- 2,044 %

Caffeine mg/d ------ 393 ------ 364 ------ 424

There do seem to be many increases of problems
from the second to third row, as mean aspartame use doubles.

Granted, this is cherry picking the data, selecting interesting
patterns.

Correlations alone do not prove any direction of causation.

Nevertheless, it may be of value to study the correlations for
increasing aspartame intake among the 4 % using over 600 mg, the
equivalent of 3 cans 12-oz cans diet soda daily. The average use for
this group is 5 cans daily.

For instance, are a minority of these heavy users displaying the great
majority of the problems that are reflected in the mean for each level
of use, with most users only having little or no increase in problems?

This is a group of about 20,000 people.

BACKGROUND:
In a few animal experiments, aspartame has been linked to
hematopoietic and brain cancers.

Most animal studies have found no increase in the risk of these or
other cancers.

Data on humans are sparse for either cancer.

Concern lingers regarding this widely used artificial sweetener.

OBJECTIVE:
We investigated prospectively whether aspartame consumption is
associated with the risk of hematopoietic cancers or gliomas
(malignant brain cancer).

METHODS:
We examined 285,079 men and 188,905 women ages 50 to 71 years in the
NIH-AARP Diet and Health Study cohort

Daily aspartame intake was derived from responses to a baseline self-
administered food frequency questionnaire that queried consumption of
four aspartame-containing beverages (soda, fruit drinks, sweetened
iced tea, and aspartame added to hot coffee and tea) during the past
year.

Histologically confirmed incident cancers were identified from eight
state cancer registries.

Multivariable-adjusted relative risks (RR) and 95% confidence
intervals (CI) were estimated using Cox proportional hazards
regression that adjusted for age, sex, ethnicity, body mass index, and
history of diabetes.

RESULTS:
During over 5 years of follow-up (1995-2000), 1,888 hematopoietic
cancers and 315 malignant gliomas were ascertained.

Higher levels of aspartame intake were not associated with the risk of
overall hematopoietic cancer
(RR for over 600 mg/d, 0.98; 95 % CI, 0.76-1.27),
glioma (RR for over 400 mg/d, 0.73; 95 % CI, 0.46-1.15;
P for inverse linear trend = 0.05),
or their subtypes in men and women.

CONCLUSIONS:
Our findings do not support the hypothesis that aspartame increases
hematopoietic or brain cancer risk. PMID: 16985027

"We cannot exclude the possibility that higher aspartame consumption
than that observed in this study may be associated with an elevated
risk of hematopoietic or brain cancers.

In the laboratory study with positive findings, animals were fed doses
starting from 4 mg up to 5,000 mg per kg body weight.

Significantly elevated lymphomas and leukemias were observed in female
rats fed 20 mg of aspartame and higher (e.g., 1,200 mg for humans
weighing 60 kg or 132 lb; refs. 13, 14).

The reported aspartame intake in our data ranged from 0 to 3,400 mg/d
with sparse numbers in the upper intake categories (under 1 %
consuming over 1,200 mg/d).

However, we did not detect any increase in risk estimates in the
highest categories (over 1,200 or 2,000 mg/d, which is equivalent to
about 7 to 11 cans of soft drinks daily) compared with the lowest
categories,
and the associations were similarly null in both men and women."

After a thorough discussion of the epidemiologic, experimental, and
other relevant data, the working group concluded that formaldehyde is
carcinogenic to humans, based on sufficient evidence in humans and in
experimental animals.

In the epidemiologic studies, there was sufficient evidence that
formaldehyde causes nasopharyngeal cancer, "strong but not sufficient"
evidence of leukemia, and limited evidence of sinonasal cancer.

The working group also concluded that 2-butoxyethanol and
1-tert-butoxy-2-propanol are not classifiable as to their
carcinogenicity to humans, each having limited evidence in
experimental animals and inadequate evidence in humans.

These three evaluations and the supporting data will be published as

This volume re-evaluates the available evidence on the carcinogenic
potential of formaldehyde, a substance that is found in the workplace
and in the environment.
Formaldehyde is widely used in resins that bind wood products, pulp
and paper; in glasswool and rockwool insulation; in plastics and
coatings, textile finishing, chemical manufacture; and as a
disinfectant and preservative.
Also evaluated are two glycol ethers, 2-butoxyethanol and 1-tert-
butoxypropan-2-ol,
which are widely used as solvents in paints and paint thinners,
coatings, glass and surface cleaners, inks, adhesives, personal-care
products, and as chemical intermediates.
As for formaldehyde, there is sufficient evidence in epidemiological
studies for nasopharyngeal cancer, strong but not sufficient evidence
for leukaemia, and limited evidence for sinonasal cancer.
The extensive scientific database on the mechanisms by which
formaldehyde can induce nasal-tract cancer in humans is considered.
These data provide strong support for the empirical observation of
nasopharyngeal cancer in humans.
In contrast, the lack of information on possible mechanisms by which
formaldehyde might increase the risk for leukaemia in humans tempered
the interpretation of the epidemiological data on that cancer.
Although this volume focuses on a qualitative assessment of the
carcinogenic potential of formaldehyde, subsequent predictions of the
risks for nasopharyngeal cancer should consider pertinent information
on mechanisms of carcinogenesis, including genotoxicity and dose-
dependent cytoxicity.
A theme common to the three evaluations is the consideration of
mechanistic information to develop and evaluate hypotheses on the
sequence of steps that lead to the induction of tumours in
experimental animals.
The hypothesized mechanisms described provide an interesting set of
cases that range from a vast literature on respiratory tract tumours
in rats induced by the inhalation of formaldehyde to some more
tentative hypotheses on the various tumours observed in animals
following exposure to both glycol ethers.
Recurring issues were the criteria that characterize a rare tumour or
how to introduce additional information to resolve difficult
questions; for example, how to consider the results of historical
controls.

International Agency for Research on Cancer, Lyon, France.

An international, interdisciplinary working group of expert scientists
met in June 2004 to develop IARC Monographs on the Evaluation of the
Carcinogenic Risk of Chemicals to Humans (IARC Monographs) on
formaldehyde, 2-butoxyethanol, and 1-tert-butoxy-2-propanol.

Each IARC Monograph includes a critical review of the pertinent
scientific literature and an evaluation of an agent's potential to
cause cancer in humans.

ASDA, Wal-Mart's UK supermarket chain, bans artificial colors, trans
fats, MSG and aspartame, Marguerite Kelly, The Washington Post: Murray
2007.08.03 ]

So far, USA print and broadcast media are deaf, blind, and dumb,
regarding recent major bans of aspartame and MSG in the UK and EU.

The EU Parliament voted July 12 to ban artificial sweeteners
in newly born and infant foods.

On May 15 four huge UK supermarket chains announced bans
of aspartame and MSG, food dyes, and many additives
to protect kids from ADHD --
Sainsbury, Tesco, Marks & Spencer, and ASDA, a unit of WalMart.

May 31: Coca-Cola and the much larger Cargill Inc.,
after years of secret development, with 24 patents,
will soon sell rebiana (stevia) in drinks and food
in the many nations where it is approved as a sweetener --
for decades a major sweetener in Japan, China, Korea, Taiwan,
Thailand, Malasia, Saint Kitts, Nevis,
Brazil, Peru, Paraguay, Uruguay, and Israel,
and an approved supplement in USA, Australia, and Canada,
according to Wikipedia.
