"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."

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
8,644 women and 4,980 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

Type of alcohol consumed, changes in intake over time and mortality:
the Leisure World Cohort Study.

annliahi@usc.edu

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.

The authors explored the relation of body mass index (BMI; weight (kg)/
height (m)**2) and weight change to all-cause mortality in the
elderly, using data from a large, population-based California cohort
study, the Leisure World Cohort Study.

They estimated relative risks of mortality associated with self-
reported BMI at study entry, BMI at age 21 years, and weight change
between age 21 and study entry.

Participants were categorized as underweight (BMI < 18.5), normal
weight (BMI 18.5-24.9), overweight (BMI 25-29.9), or obese (BMI over
30).

Of 13,451 participants aged 73 years (on average) at study entry
(1981-1985), 11,203 died during 23 years of follow-up (1981-2004).

Relative to normal weight, being underweight (relative risk (RR) =
1.51, 95 % confidence interval (CI): 1.38, 1.65)
or obese (RR = 1.25, 95% CI: 1.13, 1.38) at study entry was associated
with increased mortality.

People who were either overweight or obese at age 21 also had
increased mortality (RR = 1.17, 95 % CI: 1.09, 1.25).

Participants who lost weight between age 21 and study entry had
increased mortality regardless of their BMI category at age 21.

Obesity was significantly associated with increased mortality only
among persons under age 75 years and among never or past smokers.

This study highlights the influence on older-age mortality risk of
being overweight or obese in young adulthood and underweight or obese
in later life.  PMID: 16641311

"Participants were members of the Leisure World Cohort Study, a
population-based study initiated in 1981.

A health questionnaire was mailed on June 1, 1981, to all residents
who owned homes in Leisure World Laguna Hills, a retirement community
in California.

Residents who moved into the community after this date were sent
surveys in 1982, 1983, and 1985.

The survey was returned by 13,978 residents (61 percent).

Nonrespondents had higher hospitalization rates than respondents
during the first year of follow-up and higher death rates during the
first 3 years but not thereafter (3).

The cohort, like the population, is primarily Caucasian, educated, and
upper middle-class; two thirds are female.

The health questionnaire collected information on demographic factors,
medical history (selected data), exercise, and smoking, among other
variables.

The institutional review boards of the University of Southern
California and the University of California, Irvine, approved the
study."

"We analyzed data for 13,451 participants after deleting 527
participants with missing data for the variables of interest.

Table 1 shows the characteristics of these participants.

The average age at study entry was 73 years, the average duration of
follow-up was 13 years, and the majority of participants were women
(64 percent).

Table 1 also shows the characteristics of participants by BMI category
at study entry.

People in the higher BMI categories were younger at entry, had greater
weight gain, and were more likely to have a history of hypertension or
diabetes but were less likely to smoke or have a history of stroke or
cancer."

Health (R01CA32197 and R01AG21055), the Earl Carroll Trust Fund, and

13 mainstream research studies in 24 months showing aspartame
toxicity, also 3 relevant studies on methanol and formaldehyde: Murray
2007.10.10
http://groups.yahoo.com/group/aspartameNM/message/1464

Aspartame toxicity was shown in thirteen detailed mainstream research
studies in 24 months in work by expert teams in 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.

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
http://RMForAll.blogspot.com September 21, 2007

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 cohort ---------- 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.

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.

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.

William C Biggs MD - 14 Oct 2007 08:22 GMT
Rich,

Interesting study.

The problem with all epidemiologic studies is that they don't tell us squat
about cause and effect.

Does a diet soft drink cause excess death, or do people with diseases that
cause excess death prefer diet over regular sodas?

Either would result in the same findings.

In fact, one would expect that those who are obese (a major cause of excess
mortality) would have a relative preference for diet soft drinks over those
who are non-obese.

Those with diabetes, obese or not, would similarly prefer diet soft drinks,
and have excess mortality related to their diabetes, not their drinks.

BTW, the same group found a 15% reduction in mortality with moderate alcohol
consumption.

This is the same dilemma we were in with antidepressants and adolescents.
Depressed adolescents who took SSRI antidepressants have an elevated suicide
risk.

Many took that to mean the SSRIs caused suicidal behavior. When that
information got out, the FDA felt compelled to issue an advisory, and  many
adolescents were no longer prescribed SSRIs starting in 2004.

So after a 28% drop in teen suicides from 1990 to 2003, there was then an 8%
increase in one year, the sharpest one year increase in 15 years.

So was the cause the fact that most teens were no longer getting SSRI's as
they would have in the 1990 - 2003 time frame?  Certainly withholding SSRIs
doesn't seem to be improving matters.

The moral of the story is, epidemiological surveys tell us nothing about
cause and effect. And the conclusions drawn can not only be wrong, but make
matters worse.

Cheers,
WCB
Rich Murray - 15 Oct 2007 05:51 GMT
Thanks, William C. Biggs MD, for your thoughtful, well-informed, civil
comments.

That's why I attached the list of 13 mainstream studies, the majority
of which explore the specific harmful biochemistry of aspartame and
its three components, 50 % phenylalanine, 39 % aspartic acid, and 11 %
methanol, which the body quickly turns into formaldehyde and then
formic acid.

The expert review by M. Bouchard et al, 2001, states that evidence
exists that about 40 % of ingested methanol, radioactively labeled,
remains in the body of monkeys and other test animals for days, as
unknown products.

Formaldehyde is about as undesirable as any toxin known.

Most of us have heard about the uproar about its presence in the FEMA
mobile homes after Hurricane Katrina.

Physicians have higher rates of allergic reaction to formaldehyde, due
to their exposure to it during medical training with cadavers.  My
friend, Ken Stoller, Prof. of Pediatrics at University of New Mexico,
told me that he was so allergic to it that he had to sit at a distance
of yards from a training autopsy, and read the text to his fellow
students who carried out the procedures.

Actually, it is shocking to find out how little is actually known
about formaldehyde and formic acid toxicity in humans, especially from
long-term, low level chronic exposures.

Have you experience with people who have used 6-12 cans daily diet
drinks for years?

In mutual service,  Rich Murray
William C Biggs MD - 15 Oct 2007 07:52 GMT
Rich,

> Have you experience with people who have used 6-12 cans daily diet
> drinks for years?

Yes, and they have not shown any signs of toxicity.

We do see headaches if they try to stop them abruptly, from caffeine
withdrawal.

Were you aware that aspartame has the potential to prevent toxicity from
Ocratoxin?

Human & Experimental Toxicology, Vol. 17, No. 7, 380-386 (1998)
Subchronic effects of ochratoxin A on young adult rat brain and partial
prevention by aspartame, a sweetener

Ochratoxin is one of the most prevalant food contaminating mycotoxins.

I thought that the aspartame/methanol issues had been put to bed long ago.
It is actually quite possible to measure the serum methanol levels via
exhaled methanol. I am sure you are familiar with the commercial
breathalyzers that police use. Methanol is even more volatile than ethanol.
The actual methodology is more advanced that police breathalyzers, but the
concept is the same.

(See Lindinger, W, Hansel A, and Jordan A. On-line monitoring of volatile
organic compounds at pptv levels by means of proton-transfer-reaction mass
spectrometry (PTR-MS). Medical applications, food control and environmental
research. Int J Mass Spectrom Ion Processes 173: 191-241, 1998.)

It is quite easy to demonstrate the production of methanol from innumerable
types of foods. There is methanol production from multiple, normal,
metabolic pathways in the human, as well as degradation of various foods to
methanol by colonic bacteria.

I'm kind of surprised that this is still of interest to anyone. Maybe it's
similar to the book, "When Prophecy Fails" by Leon Festinger.

Doc, you are aware that Rich is a fanatic about this?

Debating the subject with him is like debating Darwin's

progressively redder in the face, but neither side will ever
be persuaded to change their views.

Alan,

If anything, maybe Rich will pick up a copy of  "When Prophecy Fails" and
see himself there.

For those that haven't read it, despite the title, the book has nothing to
do with religion or the debate between religion and atheism. It was written
by a social psychologist.

Rather, it was a study in the psychology of beliefs, and the interesting
observation that as the core belief is demonstrated to be more and more
implausible, the true believers will intensify their belief rather than
abandon it.

Rich, please read this one. It might let you move on with your life. It's on
Amazon.

Rich Murray - 16 Oct 2007 07:24 GMT
Hello William C Biggs, MD,

Yes, while studying for my MA in psychology, Boston University
Graduate School, 1967, I much enjoyed "When Prophecy Fails".

I myself hardly expected, however, to ever be viewed as a fanatic or
true believer about anything.

http://www.whenprophecyfails.org/

When Prophecy Fails -- A social and psychological study of a modern
group that predicted the destruction of the world.  is a book Written
by Leon Festinger, Henry Riecken, and Stanley Schachter.  Copyright
1956 by the University of Minnesota, published by Harper Torchbooks,
Harper and Row.  It is out of print but you can get it for a
reasonable price on Amazon.

I suggest that while of course an unqualified medical layman such as
myself might well reasonably be initially suspected to be a fanatic,
it is hardly prudent to view all the qualified mainstream researchers
who are currently publishing studies on aspartame toxicity in the same
light.

13 mainstream research studies in 24 months showing aspartame
toxicity,
also 3 relevant studies on methanol and formaldehyde: Murray
2007.08.17

I am also very impressed by the Lindinger results that show enormous
levels of methanol intake from fruits, due to the degradation of
pectins by bacteria in the GI tract.  Yet I find no reports of people
having hangover symptoms from these blood levels, which surely are
comparable to those studied by some reputable teams as the major cause
of alcohol hangover symptoms.  So we have have an experimental paradox
which certainly both invites and deserves thorough curiousity driven
research:

highly toxic formaldehyde, the cause of alcohol hangovers, is made by

DMDC: Dimethyl dicarbonate 200mg/L in drinks adds methanol 98 mg/L
( becomes formaldehyde in body ): EU Scientific Committee on Foods
2001.07.12: Murray 2004.01.22

http://europa.eu.int/comm/food/fs/sc/scf/out96_en.pdf

"...DMDC was evaluated by the SCF in 1990 and considered acceptable
for
the cold sterilization of soft drinks and fruit juices at levels of
addition up to 250 mg/L (1)
...DMDC decomposes primarily to CO2 and methanol ...

[ Note: Sterilization of bacteria and fungi is a toxic process,
probably due to the inevitable conversion in the body of methanol
into highly toxic formaldehyde and then formic acid. ]

The use of 200 mg DMDC/L would add 98 mg/L of methanol to wine which
already contains an average of about 140 mg/L from natural sources.

A healthy person metabolises 1500 mg methanol/hr without any
physiological problems and this should be compared to the amount of up
to 240 mg/L methanol in wine, treated with DMDC up to 200 mg/L.

Metabolism of the amounts of methanol resulting from consumption of
wine
containing such levels is therefore well within the capacity of the
human body.
Thus consumption of even large quantities of wine would not pose any
hazards from methanol.

Conclusion

The formation of methanol and other reaction products following the
use
of DMDC for the treatment of alcoholic beverages and wine is similar
to
that formed in non-alcoholic beverages.
Therefore the previous opinion on the use of DMDC for non-alcoholic
beverages (1) is equally applicable to wines treated with DMDC."

However, research shows that the methanol in dark wines and liquors is
made into formaldehyde by the body, causing the toxic symptoms of
hangovers.

[ Han-Kyu Lee ]

A hangover is characterized by the unpleasant physical and mental
symptoms that occur between 8 and 16 hours after drinking alcohol.

After inducing experimental hangover in normal individuals,
we measured the methanol concentration prior to
and after alcohol consumption
and we assessed the association between the hangover condition
and the blood methanol level.

A total of 18 normal adult males participated in this study.

They did not have any previous histories of psychiatric
or medical disorders.

The blood ethanol concentration prior to the alcohol intake
(2.26+/-2.08) was not significantly different from that
13 hours after the alcohol consumption (3.12+/-2.38).

However, the difference of methanol concentration
between the day of experiment (prior to the alcohol intake)
and the next day (13 hours after the alcohol intake)
was significant (2.62+/-1.33/l vs. 3.88+/-2.10/l, respectively).

A significant positive correlation was observed
between the changes of blood methanol concentration
and hangover subjective scale score increment when covarying
for the changes of blood ethanol level (r=0.498, p<0.05).

This result suggests the possible correlation of methanol
as well as its toxic metabolite to hangover. PMID: 16318957

[ The toxic metabolite of methanol is formaldehyde, which in turn
partially becomes formic acid -- both potent cumulative toxins
that are the actual cause of the toxicity of methanol.]

methanol (formaldehyde, formic acid) disposition: Bouchard M et al,
full
plain text, 2001: substantial sources are degradation of fruit
pectins,
liquors, aspartame, smoke: Murray 2005.04.02

Fully 11 % of aspartame is methanol -- 1,120 mg aspartame
in 2 L 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 L of water.

ATSDR: EPA limit 1 ppm formaldehyde in drinking water July 1999:
Murray 2002.05.30

This long-term low-level chronic toxic exposure leads to typical
patterns of increasingly severe complex symptoms,
starting with headache, fatigue, joint pain, irritability, memory
loss,
rashes, and leading to vision and eye problems, and even seizures.
In many cases there is addiction. Probably there are immune system
disorders, with a hypersensitivity to these toxins and other
chemicals.

So far, USA print and broadcast media are deaf, blind, and dumb,

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.

aspartame research debate: Lowry: Murray 2000.07.23

Sunday, July 23 2000 Hello Mark and Matt Lowry,

I am very willing to engage in a prolonged,
systematic public debate on aspartame toxicity
research. I will continue to share all posts, unedited, with my
discussion group aspartameNM@egroups.com ,
another open discussion group, virtually unused so far except by me,
at
www.bevnet.com/bevboard/cgi-bin/Ultimate.cgi?action=intro
"The Dangers of Aspartame",
and five news groups: bionet.toxicology, bionet.neuroscience,
sci.med.nutrition, sci.bio.misc, and alt.discuss.health.toxicity ,
which
all maintain permanent, searchable archives, accessible by
www.deja.com/usenet/ , as well as submit to Lancet
Interactive discussion group: Aspartame toxicity- fact or fiction? at
www.TheLancet.com , and to varying dozens of others on my private
list.

Thus, others will hopefully join in, since the three of us are either
laymen or not specifically qualified to evaluate adequately many
relevant research studies. The overall results are certainly going to
be
of value, and will set a precedent for responsible public debate on
the Net
about many other vital issues. I suggest we all relinquish all
copyright claims, releasing our posts to be freely used, resent, and
otherwise published, as long as we are always included as the original
authors.

It is convenient to limit each post to 30K, about 10 pages printed,
because that is often a limit for lifting and copying in a single
operation.

To commence, I am grateful for the feedback that the term, used by me,
"pro-aspartame", would often be misconstrued to imply that someone is
strongly committed to aspartame, for my intention was to indicate a
general dichotomy: those who criticize aspartame vs those who defend
it. For two decades and longer, these have generally been two very
divided camps. Other toxicity issues for which this same striking
polarization exists are: MSG, mercury dental amalgam, fluoride,
and, actually, many others. More and more, the lay and professional
public can immediately access well-organized, large, detailed websites
for both sides of many controversial toxins. This is a very good
development for world society. What is needed is to develop
traditions and precedents for responsible public dialogues among
polarized positions, that facilitate consensus building at the
grassroots level, faster than the slow, cumbersome, sporadic,
biased, venues of bureaucracy, business, medicine, education,
media, and law.

It is not necessary to come to definitive proof that aspartame
causes headache, whether as a "toxin" or an "allergen" in many
users, or any other disease. It is enough to make the case that
aspartame is likely a causal factor in as many as 1% of users, for
that would be over a million in the USA alone, who surely would
deserve to be informed that they might consider the entirely
safe and reasonable step of giving up all aspartame use for a
few months.

It is possible to quickly come to experimental certitude, or not, that
moderate use of aspartame in humans leads to cumulative adducts of
formaldehyde, bound to DNA and proteins in brain, liver, kidneys,
retina, and other tissues, as Trocho reported for rats. This proof
would in practice compel the recall of aspartame, as the toxicity
of formaldehyde is surely indubitable, and entirely consistent with
the very wide range of symtoms reported by thousands of case
reports. One very useful result of our debate would be to make
many ambitious and competent researchers aware that this
scientific and medical plum is ripe for the plucking. Contrariwise,
the aspartame industry can improve their case greatly within
a few months.

Thank you for the references on recent research, a few of which
I have already investigated and posted publicly about. I will
take up each reference, one at a time, in this debate. Note that
Thomas R. Tephly, whose research often is funded by
the aspartame industry, has published a letter, not a
peer-reviewed paper, criticizing the Trocho claims, and I
have read it, but, as a layman, am not convinced. The Trocho
paper is on the Net, available for review by everyone. Why
don't we make critiquing it our first priority? Does anyone
know whether a replication with humans is being attempted?

Abstract:
Adult male rats were given an oral dose of 10 mg/kg aspartame,
14C-labelled in the methanol carbon. At timed intervals of up to 6
hours, the radioactivity in plasma and several organs was
investigated.
Most of the radioactivity found (>98% in plasma, >75% in liver) was
bound to protein. Label present in liver, plasma and kidney was in the
range of 1-2% of total radioactivity administered per g or mL,
changing
little with time. Other organs (brown and white adipose tissues,
muscle, brain, cornea and retina) contained levels of label in the
range of 1/12th to 1/10th of that of liver. In all, the rat retained,
6 hours after administration, about 5% of the label, half of it in the
liver. The specific radioactivity of tissue protein, RNA and DNA was
quite uniform. The protein label was concentrated in amino acids,
different from methionine, and largely coincident with the result of
protein exposure to labelled formaldehyde. DNA radioactivity was
essentially in a single different adduct base, different from the
normal bases present in DNA. The nature of the tissue label
accumulated was, thus, a direct consequence of formaldehyde binding
to tissue structures. The administration of labelled aspartame to a
group of cirrhotic rats resulted in comparable label retention by
tissue components, which suggests that liver function(or its defect)
has little effect on formaldehyde formation from aspartame and binding
to biological components. The chronic treatment of a series of rats
with 200 mg/kg of non-labelled aspartame during 10 days results in
the accumulation of even more label when given the radioactive bolus,
suggesting that the amount of formaldehyde adducts coming from
aspartame in tissue proteins and nucleic acids may be cumulative.
It is concluded that aspartame consumption may constitute a hazard
because of its contribution to the formation of formaldehyde adducts.

A recent paper by Trocho et al. (1) describes experiments meant to
show
that formaldehyde adducts are formed when rats are administered the
sweetener aspartame. These authors assume that the methanol carbon of
aspartame generates formaldehyde which then forms adducts with
protein,
DNA, and RNA. Doses employed range widely. In this letter, studies
which have been published previously and which were not cited by these
authors are reviewed in order to put into perspective the disposition
of methanol and formaldehyde in monkeys and humans, species relevant
to
the toxicity of methanol and its toxic metabolite, formic acid.

Mr. Murray,
You state, "If there is scientific, adequate, and unbiased
experimental proof of the safety of aspartame, then I want to know
about it immediately in full detail. "

You can't prove a negative, such as "Aspartame isn't dangerous." I
am merely looking for proof of a positive: "Aspartame is dangerous."
There are anecdotes, there are (flawed) retrospective studies...I
haven't seen any proof of aspartame's danger or implication,
in a causal way, to any human disease.

I am not "pro-aspartame". It is more accurate to say that I am
pro-truth or pro-fact. That's all.

I guess we're all awaiting the results of the King's College trials.

Why is it that you refer to people who are skeptical of the claims of
"aspartame poisoning" as "pro-aspartamers"? My brother, myself, and
Alan Raetz are not pro-aspartame, we are merely skeptical of the
claims
made that aspartame is responsible for the long list of diseases and
maladies (a list which seems to grow almost daily) espoused by many
high-profile anti-aspartame advocates. We are further very skeptical
of their claims to some collusion between Monsanto and the Federal
Government. Just because we are skeptical doesn't mean we are
pro-aspartame; I honestly couldn't care less whether or not people
used the stuff. This blatant labeling of those skeptical of your
position smacks of a "If you're not with us you're against us"
black-and-white mentality. I am not interested in getting overly
involved with individuals or groups who make such assertions.

If the group of professionals that you mention are able to, via valid
peer-reviewed science, convince more and more skeptical members of the
scientific and medical communities of the validity of your claims,
more
power to you. However, until I start seeing more consistent evidence
that aspartame does what many of you claim it does,
I have no real reason to change my views.

I do believe that I provided you with a great many articles and
abstracts from PubMed-Medline that did indeed attest to the safety
of aspartame. Did you lose or misplace these articles, or were they
conveniently ignored or written off as "industry funded"? Funny thing
is that everytime I provide peer-reviewed research on this issue to
most anti-aspartamers, they write it off as industry funded without
providing any evidence to support that claim. As an act of good
faith, I'll provide these citations again in a follow-up email.

When I examine the medical studies critical of aspartame, I don't call
them invalid unless there is a reason to do so, like follow-up
research
that doesn't yield consistent results or a specific study pointing out
methodological errors in the original research. I do not (unlike many
anti-aspartame advocates) make it a policy to blatantly dismiss any
study or research out of hand.

Well, there were apparently flaws in the Trocho study, which is
pointed
out by the following reference, a reference which I have already
provided to you. Is this reference yet another "industry funded"
bunch of propoganda?

Until you and your group can produce and reproduce consistent, valid,
peer-reviewed studies that support the claims that aspartame causes
cancer, multiple sclerosis, lupus, etc. those who are skeptical of
your
claims (like me, my brother, and Alan Raetz) will remain skeptical.
If, however, your research (and the research of other independent
scientists) produces consistently verifiable and reproducible results
that conclusively show a cause-and-effect link between aspartame
usage and the aforementioned maladies, then we and many others in
the scientific and medical communities will change our minds... but
you have to convince us first.

The non-nutritive sweeteners acesulfame-K, aspartame, cyclamate,
saccharin and sucralose were tested for DNA damaging activity in
the rat hepatocyte/DNA repair assay. Using hepatocytes from F344
and Sprague-Dawley male rats, all were inactive despite strong

Aspartame and acesulfame-K, non-nutritive sweeteners, are permitted
individually in diets and beverages. These sweeteners of different
classes, used in combination, have been found to possess a synergistic
sweetening effect. Whether they also have a synergistic genotoxic
effect
is unknown.
Swiss Albino male mice were exposed to blends of aspartame
(3.5, 35, 350 mg/kg body weight) and acesulfame-K (1.5, 15 and
150 mg/kg body weight) by gavage. Bone marrow cells isolated from
femora were analysed for chromosome aberrations. Statistical analysis
of the results show that aspartame in combination with acesulfame-K
is not significantly genotoxic.

Anxiety in mice following acute aspartame and ethanol exposure.

The purpose of the present study was to look at the effect of
aspartame
on the anxiolytic actions of ethanol. Previous research has shown that
ethanol reliably produces an anxiolytic effect on rodent's plus-maze
performance. There have been anecdotal reports that aspartame
increases anxiety. CD-1 male mice were given i.p. aspartame doses
of vehicle, 1000, or 2000 mg/kg, followed 30 min later by i.p. ethanol
doses of 1.6 g/kg or vehicle. Animals were then placed in an open
field, then tested in the plus-maze. Results determined that the
aspartame condition had no significant effect on anxiety-related
behavior, nor did it alter the anxiolytic actions of ethanol.
Thus, acute high dose exposure to aspartame does not appear
to affect anxiety-related behaviors. PMID: 10680719, UI: 20142912

The method of chromosome aberration count in the bone marrow cells of
C57B1/6 mice was used to study the influence of aspartame on the
cytogenetic effects of dioxydin and cyclophosphan. Aspartame
(0.4-40 mg/kg) was found to possess antimutagenic properties in
relation
to the listed mutagens. The discovered antimutagenic activity of
aspartame was manifested more when it was injected
for 5 days before the administration of a mutagen,
whereas in joint administration of aspartame
with the mutagens, the substitute for sugar did not change the
clastogenic effect of dioxydin and cyclophosphan.

Comments on the purported generation of formaldehyde and adduct

A recent paper by Trocho et al. (1) describes experiments meant to
show
that formaldehyde adducts are formed when rats are administered the
sweetener aspartame. These authors assume that the methanol carbon
of aspartame generates formaldehyde which then forms adducts with
protein, DNA, and RNA. Doses employed range widely. In this letter,
studies which have been published previously and which were not cited
by these authors are reviewed in order to put into perspective the
disposition of methanol and formaldehyde in monkeys and humans,
species relevant to the toxicity of methanol and its toxic metabolite,
formic acid. PMID: 10503962, UI: 99431287

Interference of rheumatoid factor activity by aspartame, a dipeptide
methyl ester.

City 73104, USA.

Circulating autoimmune complexes of IgM rheumatoid factors (RF) bound
to
the Fc portions of normal, polyclonal IgG antibodies are frequently
present in humans with rheumatoid arthritis (RA).
The sweet tasting methyl ester of
L-Asp-L-Phe (aspartame or APM) was found to relieve pain and improve
joint mobility in subjects with osteo- and mixed osteo/rheumatoid
arthritis
[Edmundson, A. B. and Manion, C. V. (1998). Clin. Pharmac. Ther. 63,
580-593]. These clinical observations prompted the testing of the
inhibition by APM of the binding interactions of human IgM RFs with
IgG
Fc regions.
The propensity of APM to inhibit IgM RF binding was assessed by
competitive enzyme immunoassays with solid-phase human IgG. Ten RA
serum samples and three purified monoclonal cryoglobulins, all of
which
had RF activity, were tested in this system. We found that the
presence
of APM significantly reduced the binding of IgM RFs.
The inhibitory propensity
of APM with monoclonal RF cryoglobulins was increased by the addition
of CaCl(2) to the binding buffer. Similar inhibition of the binding of
RA derived RFs to IgG was observed for Asp-Phe
and its amidated derivative,
indicating that the methyl ester is not required for APM's interaction
with IgM antibodies.
A human (Mez) IgM known to bind octameric peptides
derived from the Fc portion of a human IgG(1) antibody was tested for
binding of dipeptides by the Pepscan method of combinatorial
chemistry.
The relative binding constants of Asp-Phe and Phe-Asp were ranked
among the highest values for 400 possible combinations of the 20 most
common amino acids. Possible blocking interactions of APM were
explored by computer-assisted docking studies with the model of a
complex of an RF Fab with the Fc of a human IgG(4) antibody.
Modeling of ternary immune complexes revealed a few key residues,
which could act as molecular recognition sites for APM. A structural
hypothesis is presented to explain the observed interference with RF
reactivity by APM. Extrapolations of the current results suggest that
APM may inhibit the binding of IgG in a substantial proportion of IgM
RFs. Interference of RF reactivity, especially in RA patients, may
alleviate the pain and immobility resulting from chronic inflammation
of the joints. Copyright 1999 John Wiley & Sons, Ltd.

Aspartame: neuropsychologic and neurophysiologic evaluation of acute
and
chronic effects.
Spiers PA, Sabounjian L, Reiner A, Myers DK, Wurtman J, Schomer DL
Clinical Research Center, Massachusetts Institute of Technology,
Cambridge 02139, USA.
BACKGROUND: Neurobehavioral symptoms have been reported anecdotally
with aspartame. OBJECTIVE: This study sought to determine whether
aspartame can disrupt cognitive, neurophysiologic, or behavioral
functioning in
normal individuals. DESIGN: Forty-eight healthy volunteers completed a
randomized, double-blind, placebo-controlled, crossover study. The
first
month was aspartame free. Subjects then consumed sodas and capsules
with placebo, aspartame, or sucrose for 20 d each. Order was
randomized
and subjects were assigned to either a high-
(45 mg x kg body wt(-1) x d(-1)) or low-
(15 mg x kg body wt(-1) x d(-1)) dose aspartame group
Neuropsychologic and laboratory testing was done on day 10 of
each treatment period to determine possible acute effects and on
day 20 for possible chronic effects. RESULTS:
Plasma phenylalanine concentrations increased significantly during
aspartame treatment. Neuropsychologic results; adverse experiences;
amino acid, insulin, and glucose values; and
electroencephalograms were compared by
sex and by treatment. No significant differences were found for any
dependent measure. CONCLUSION: Large daily doses of aspartame
had no effect on neuropsychologic, neurophysiologic, or behavioral
functioning in healthy young adults.

How aspartame prevents the toxicity of ochratoxin A.
Creppy EE, Baudrimont I, Anne-Marie
Toxicology Department, University of Bordeaux, France.

The ubiquitous mycotoxin ochratoxin A (OTA) is found as a frequent
contaminant of a large variety of food and feed and beverage such as
beer, coffee and win. It is produced as a secondary metabolite of
moulds
from Aspergillus and Penicillium genera. Ochratoxin A has been shown
experimentally to inhibit protein synthesis by competition with
phenylalanine its structural analogue and also to enhance oxygen
reactive radicals production. The combination of these basic
mechanisms
with the unusual long plasma half-life time (35 days in non-human
primates and in humans), the metabolisation
of OTA into still active derivatives
and glutathione conjugate both potentially reactive with cellular
macromolecules including DNA could explain the multiple toxic effects,
cytotoxicity, teratogenicity, genotoxicity, mutagenicity and
carcinogenicity.
A relation was first recognised between exposure to OTA in the Balkan
geographical area and Balkan Endemic Nephropathy (BEN) with a high
incidence (nearly 50 times higher than normal) of urinary tract
tumours.
Exposure rates of OTA are measurable in blood of humans and animals
and are established in several countries including Scandinavia,
Germany,
France, Italy, Canada, Japan and Northern Africa mainly Tunisia and
Egypt. The impact of OTA exposure in non-endemic areas in the world
is not known, the rates of exposure being not correlated with the
disease records, especially in developed
countries, due to lake of well-designed
epidemiological studies, genetic polymorphism and maybe to dietary
contents of radical scavengers and antioxidants. However
the incidence and mortality rates of renal cancer are increasing in
European countries and Northern Africa which could be a global
resultant
of human exposure to natural compounds in food such as mycotoxins and
especially ochratoxin A. In addition to special care to prevent the
growth of moulds and detoxification
measures there was a need for the prevention
of the OTA-induced toxic effects once the toxin is ingested. For this
purpose
several compound have been studied including some therapeutic agents
such as piroxicam which cannot be proposed for a large scale use in
humans for preventive purpose. Among other
compounds, Aspartame, already used
as sweetener has shown a real effectiveness in vivo confirmed largely
in
vitro. When rats exposed to OTA (289 micrograms/kg) by oral route
every
two days are given 25 mg/kg similarly for several weeks, all the toxic
effects including genotoxicity are very efficiently prevented as shown
for
example by the disappearance of DNA-adducts in tissues excised from
treated animals. Aspartame is also effective in washing out the toxin
when
given
afterwards to animals intoxicated by the same oTA doses for several
weeks. In vitro, provided that it is added in cell culture medium
before
OTA it prevent significantly the inhibition
of protein synthesis and lipid
peroxidation induced by the toxin. Obviously the molecular mechanism
mediating the preventive effect of Aspartame is the delivery of
phenylalanine by cleavage of the peptide but also the direct effect of
the peptide on the bending capacity and transport of the toxin in vivo
and in vitro. As a matter of fact when
Aspartame is given to animals or added
in culture medium the amount of peptide found unchanged (10-15%) may
account for a preventive effect as entire peptide.

Attention-deficit hyperactivity disorder in children.
Baxter PS
Department of Paediatrics, Northern General Hospital, Sheffield, UK.

Attention-deficit hyperactivity disorder has been redefined in the
classifications in the International Classification of Disease, 10th
revision and Diagnostic and Statistical Manual of Mental Disorders,
fourth edition. The definitions are more concordant than their
predecessors and reemphasize the
distinction between inattentiveness and hyperactivity.
The causes and mechanisms are still uncertain, but dietary sugar or
aspartame and thyroid dysfunction do not seem to be major factors.
Specific subgroups, such as children
with comorbid psychologic disorders,
tic disorders, or mental handicap, seem to have different origins,
natural history, prognoses, and responses to treatment, reflecting the
heterogeneous nature of the disorder. Psychostimulant therapy has
unquestioned short-term effects on behavior but less certain benefits
on long-term psychosocial outcome or on academic performance.

Biochemical and clinical effects of aspartame in patients with
chronic,
stable alcoholic liver disease.
Hertelendy ZI, Mendenhall CL, Rouster SD, Marshall L, Weesner R
Division of Hepatic Research, Department of Veterans Affairs Medical
Center, Cincinnati, Ohio.

Aspartame is an artificial sweetener completely metabolized in the gut
and absorbed as aspartate, phenylalanine, and methanol. Phenylalanine
is
thought to mediate or exacerbate hepatic encephalopathy, and an
impaired
liver may not be able to cope with the ammoniagenic properties of the
amino acid constituents, or adequately metabolize methanol. Thus, we
compared the clinical and biochemical effects of a single ingestion of
aspartame (15 mg/kg) to skim milk (phenylalanine content equimolar to
aspartame) and placebo in patients with chronic, alcoholic liver
disease
in a randomized, crossover study.
Aspartame produced an elevation of plasma
phenylalanine significantly greater than milk and placebo
(Cmax 14.55 +/- 7.38, 10.95 +/- 4.95, 8.84 +/- 4.55 mumol/dl,
respectively; p < 0.01). However, quantified encephalopathic changes
were observed only with milk (p < 0.05). Plasma aspartate, methanol,
formate, and ammonia levels remained unchanged after all treatments.
The lack of clinical derangements in encephalopathic indices,
methanol accumulation, or biochemical changes in liver status
suggests that a single large dose of aspartame (representing 5 times
the average daily intake of adults) may be used safely by patients
with
chronic, stable liver disease.

Aspartame use in Parkinson's disease.
Karstaedt PJ, Pincus JH
Department of Neurology, Georgetown University Hospital, Washington,

20007.

The artificial sweetener aspartame (NutraSweet) is hydrolyzed in the
gut
as phenylalanine (PA), a large neutral amino acid (LNAA). LNAAs
compete
with levodopa for uptake into the brain. To determine the effect of
aspartame on levodopa-treated Parkinson's
disease (PD) patients, we studied 18 PD
patients with protein-sensitive motor fluctuations by administering in
a
double-blind and single-crossover design, on alternate days, aspartame
(600 or 1,200 mg) and placebo. Every hour, we performed a motor
examination and drew blood to estimate
plasma LNAA, PA, and levodopa levels.
Six-hundred mg of aspartame had no effect
on plasma PA or motor status. Although
1,200 mg of aspartame significantly increased plasma PA, motor
performance
did
not deteriorate. Aspartame consumption in amounts well in excess of
what
would be consumed by heavy users of aspartame-sweetened products has
no
adverse effect on PD patients.

IDS: PMID: 2861297 UI: 85237822
ABSTRACT: This report examines the safety issues related to the
nutritive sweetener aspartame, including possible toxic effects of
aspartame's component amino acids, aspartic acid and phenylalanine,
and
its major decomposition products, methanol and diketopiperazine, and
the
potential synergistic effect of aspartame and dietary carbohydrate on
brain neurochemicals. Available evidence suggests that consumption of
aspartame by normal humans is safe and is not associated with serious
adverse health effects. Individuals who need to control their
phenylalanine intake should handle aspartame
like any other source of phenylalanine.

4 - Metabolism and toxicology:

Both in laboratory animals and in humans, aspartame is metabolised in
the
gastrointestinal tractus into methanol, aspartic acid and
phenylalanine.

On a weight basis, metabolism of aspartame generates approximately 50%
phenylalanine, 40% aspartic acid and 10% methanol. [ 11% exactly ]

Metabolism occurs in the intestinal lumen and in the enterocytes
(Karim et
al., 1996; Stegink et al., 1996).

It has been reported that a small proportion of the aspartame (10-12%
of the
intake) might be absorbed without metabolisation but this result
requires
confirmation (Creppy et al., 1998).

Ochratoxin A (OTA) is a mycotoxin produced by Aspergillus ochraceus as
well
as other moulds.
This mycotoxin contaminates animal feed and food. OTA is
immunosuppressive,
genotoxic, teratogenic, carcinogenic and is nephrotoxic in all animal
species studied so far.
OTA inhibits protein synthesis and induces lipid peroxidation.
Since it seems impossible to avoid completely contamination of
foodstuffs by
toxigenic fungi, it is necessary to investigate the possible ways of
limiting such toxicity.
An attempt to prevent OTA-induced nephrotoxic and genotoxic effects,
mainly
the karyomegaly, has been made in vivo using aspartame
(L-aspartyl-L-phenylalanine methyl ester), a structural analogue of
both OTA
and phenylalanine.
Aspartame (25 mg/kg body weight) prevented most of the nephrotoxic
effects
induced by OTA (289 microg/kg body weight).
It also showed some utility in preventing morphological and
histological
damage, mainly the karyomegaly.
The protective effects of aspartame on OTA-induced nephrotoxicity
could be
based on several mechanisms related to competitive binding to plasma
proteins, to transport or tissue distribution in the kidney or to the
elimination of the toxin in the urine. PMID: 11409539
