Calorie-free stevia's 11-year war with FDA
BY ERICA ORDEN Special to Newsday May 2, 2006
[ Erica Orden is a master's candidate at the Columbia University Graduate
School of Journalism.
Erica Tracey Orden eo88@... ]
To many people these days, simply sweetening a cup of coffee
is practically akin to picking a poison. Sugar or honey?
Too many calories. Equal or Nutrasweet? Too many health risks,
especially given recent reports detailing diet soda's dangerously high
levels of the cancer-causing compound benzene.
So to the sweet-toothed consumer, the increasingly popular, all natural,
calorie-free substance called stevia sounds too good to be true.
And to the U.S. Food and Drug Administration, it is.
For the past 11 years, while artificial sweeteners like Splenda, Equal and
Nutrasweet have dominated the diet-conscious market, the stevia
industry and the FDA have been at odds over whether the additive
poses health risks.
But with sales of the plant-based substance, indigenous to South America,
growing rapidly in the past few years, stevia's sticky situation is creating
an increasingly complex marketplace for consumers,
manufacturers and retailers.
FDA hard to convince
Though the stevia industry promotes it as the only natural, no-calorie
way to sweeten foods and drinks and denies any health risks,
citing the heavy use of the substance in Japan since the 1970s
without any major reported safety concerns, the FDA isn't convinced.
Since 1995, the FDA has banned the use of stevia as a sweetener,
approving it only for use as a dietary supplement because
"available toxicological information on stevia is inadequate to
demonstrate its safety as a food additive or to affirm its status as GRAS
[generally recognized as safe]."
But consumers looking for alternatives to sugar and to chemical
sweeteners keep snapping it up.
In recent years, the consumption of stevia, which is sold in powder,
tablet and liquid form and has a slightly bitter taste, has ballooned.
Sales of stevia in the United States reached about $45 million in 2005,
up nearly 25 percent from the previous year's sales,
according to the Nutrition Business Journal,
an industry guide to market research.
Once limited to obscure health food stores, stevia can now be found
at Trader Joe's stores, Whole Foods and King Kullen stores
across Long Island.
A well-kept secret
But despite its growing consumer base, stevia's long-term prospects
are severely limited under FDA regulations. For one thing,
most consumers know little to nothing about the plant derivative
because government regulations prevent even retail outlets from
explaining much about the substance.
Even diabetics, sweetener-savvy consumers and potentially some of
stevia's most devoted fans, aren't sure what to make of the product.
While nutritionists, including those who have worked in conjunction
with the American Diabetes Association like Virginia-based
consultant Robyn Webb, recommend stevia to diabetics
as a safe way to sweeten foods and drinks, the ADA refuses
to endorse it because it looks to the FDA for dietary guidelines.
And while stevia distributors are pleased with the recent growth
of their industry, some worry about the future of their marketplace.
"The true growth is in food processors putting it in food products,
and that will only come when the FDA approves it,"
says Warren Sablosky, 52, president of NuNaturals,
an Arizona-based stevia distributor that sells pure extract to Wild Oats
and Whole Foods Markets. "A lot of big food producers don't want to
sit on the legal line."
But some have taken the plunge. In January 2004, Steaz,
a Pennsylvania-based natural soda manufacturer, introduced a diet line
made with stevia rather than aspartame or Nutrasweet.
To comply with the legal guidelines, the company can't market it as a
soda or even as a beverage (it calls the product a dietary supplement)
and must list "supplement facts" rather than "nutrition facts"
on its back label.
Sales on the rise
But for Steaz, the marketing maneuvering was worth the trouble.
The company's diet black cherry flavor is now its top-selling item
at national grocery chain Wild Oats, and sales of the diet line
have increased 200 percent over each of the past two years,
according to Eric Schnell, 35, co-founder of Steaz.
"The natural community has embraced the brand," Schnell says.
Still, the general public, even consumers wary of artificial sweeteners,
may not be quite as quick to make the switch.
"It's not as good as sugar," said Sigal Elias, 41, of Great Neck,
as she tried a tiny taste of pure stevia alongside her two children,
Edan, 13, and Romi, 11, at a recent Earth Day celebration
outside Grand Central Terminal. "Usually, we drink diet soda,
but now we're trying to eliminate it. Because of the side effects,
we're kind of concerned," she admitted,
"but we love the flavor of Splenda."

Abstract:
In a study of the impact of aspartame on biochemical oscillations,
we examined the rhythms of blood glucose, plasma cholesterol,
and protein and serum aspartate transaminase (AST) in experimental rats.
Our results showed acrophase delays in glucose, total protein
and advances in AST rhythms and increased mesor (in AST),
amplitude (in cholesterol) and decreased amplitude values
(in glucose, AST) in aspartame treated animals.
Oral administration of aspartame might lead to increased levels
of aspartate in brain which could alter the characteristics of biochemical
variables possibly by modulating the transmission in several areas/nuclei
in brain including retinohypothalamic tract (RHT)
and suprachiasmatic nuclei (SCN).

Monosodium glutamate affects the temporal
characteristics of biochemical variables in Wistar rats.
Thamilarasan Manivasagam, Perumal Subramanian
Monosodium glutamate (MSG) was administrated chronically for 60
days to Wistar rats
and 24 h rhythms of glucose, Cholesterol, total protein and
alkaline phosphatase were studied.
MSG treatment was found to cause acrophase delays in the glucose
and alkaline phosphatase rhythms and advances in acrophases of
cholesterol and total protein levels.
Amplitude and mesor values of these rhythms were found to be
altered during MSG treatment.
Glutamate levels in the brain were found to be significantly increased,
which could alter these biochemical rhythms by modulating the
transmission in retinohypothalamic tract and in the hypothalamic nuclei,
probably including suprachiasmatic nuclei.
Key words: circadian rhythm, monosodium glutamate, glucose,
cholesterol, total protein, alkaline phosphatase
"MSG, 600 mg/kg (4) was injected subcutaneously to group II rats
every day (at irregular intervals) for 60 days." [ 6 rats ]

Dark wines and liquors, as well as aspartame, provide
similar levels of methanol, above 120 mg daily, for
long-term heavy users, 2 L daily, about 6 cans.
Within hours, methanol is inevitably largely turned into formaldehyde,
and thence largely into formic acid -- the major causes of the dreaded
symptoms of "next morning" hangover.
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). If 30% of the methanol is turned
into formaldehyde, the amount of formaldehyde, 37 mg,
is 18.5 times the USA EPA limit for daily formaldehyde in
drinking water, 2.0 mg in 2 L average daily drinking water.

Since no adaquate data has ever been published on the exact disposition
of toxic metabolites in specific tissues in humans of the 11% methanol
component of aspartame, the many studies on morning-after hangover
from the methanol impurity in alcohol drinks are the main available
resource to date.
Jones AW (1987) found next-morning hangover from red wine with
100 to 150 mg methanol
(9.5% w/v ethanol, 100 mg/l methanol, 0.01%,
one part in ten thousand).

The minimum lethal dose of methanol

ethyl alcohol is more toxic than methanol to these test animals (43)."

As a medical layman, I suggest that evidence mandates immediate

sources as co-factors in epidemiology, research, diagnosis,
and treatment in a wide variety of disorders.
Folic acid, from fruits and vegetables, plays a role by powerfully
protecting against methanol (formaldehyde) toxicity.
Many common drugs, such as aspirin, interfere with folic acid,
as do some mutations in relevant enzymes.
The majority of aspartame reactors are female.

First experimental demonstration of the multipotential carcinogenic
effects of aspartame administered in the feed to sprague-dawley rats.

Cesare Maltoni Cancer Research Center, European Ramazzini
Foundation of Oncology and Environmental Sciences, Bologna, Italy.
The Cesare Maltoni Cancer Research Center of the European Ramazzini
Foundation has conducted a long-term bioassay on aspartame (APM),
a widely used artificial sweetener.
APM was administered with feed to 8-week-old Sprague-Dawley rats
(100-150/sex/group), at concentrations of
100,000, 50,000, 10,000, 2,000, 400, 80, or 0 ppm.
The treatment lasted until natural death, at which time
all deceased animals underwent complete necropsy.
Histopathologic evaluation of all pathologic lesions and of all organs
and tissues collected was routinely performed
on each animal of all experimental groups.
The results of the study show for the first time that APM,
in our experimental conditions, causes
a) an increased incidence of malignant-tumor-bearing animals
with a positive significant trend in males (p </= 0.05)
and in females (p </= 0.01),
in particular those females treated at 50,000 ppm (p </= 0.01);
b) an increase in lymphomas and leukemias
with a positive significant trend in both males (p </= 0.05)
and females (p </= 0.01),
in particular in females treated at doses of
100,000 (p </= 0.01), 50,000 (p </= 0.01), 10,000 (p </= 0.05),
2,000 (p </= 0.05), or 400 ppm (p </= 0.01);
c) a statistically significant increased incidence,
with a positive significant trend (p </= 0.01),
of transitional cell carcinomas of the renal pelvis and ureter and their
precursors (dysplasias) in females treated at
100,000 (p </= 0.01), 50,000 (p </= 0.01), 10,000 (p </= 0.01),
2,000 (p </= 0.05), or 400 ppm (p </= 0.05);
and d) an increased incidence of malignant schwannomas
of peripheral nerves with a positive trend (p </= 0.05) in males.
The results of this mega-experiment indicate that APM
is a multipotential carcinogenic agent,
even at a daily dose of 20 mg/kg body weight,
much less than the current acceptable daily intake. [ 50 mg/kg bw ]
On the basis of these results,
a reevaluation of the present guidelines
on the use and consumption of APM is urgent
and cannot be delayed.
Key words: artificial sweetener, aspartame, carcinogenicity,
lymphomas, malignant schwannomas, rats, renal pelvis carcinomas.

Investigations into the metabolism of APM have shown that,
in rodents, nonhuman primates, and humans,
it is metabolized in the gastrointestinal tract into three constituents --
aspartic acid, phenylalanine, and methanol --
which are absorbed into the systemic circulation (Ranney et al. 1976).
For each molecule of APM,
one molecule of each constituent is produced.
After absorption, they are then used, metabolized, and/or excreted by
the body following the same metabolic pathways
as when consumed through the ordinary diet:
aspartate is transformed into alanine plus oxaloacetate (Stegink 1984);
phenylalanine is transformed mainly into tyrosine and, to a smaller extent,
phenylethylamine and phenylpyruvate (Harper 1984);
and methanol is transformed into formaldehyde and then to formic acid
(Opperman 1984).

Methyl alcohol was administered in drinking water
supplied ad libitum at doses of
20,000, 5,000, 500, or 0 ppm to groups of male and female
Sprague-Dawley rats 8 weeks old at the start of the experiment.
Animals were kept under observation until spontaneous death.
Ethyl alcohol was administered by ingestion in drinking water at a
concentration of 10% or 0% supplied ad libitum to groups of male and
female Sprague-Dawley rats; breeders and offspring were included in
the experiment.
Treatment started at 39 weeks of age (breeders), 7 days before mating,
or from embryo life (offspring) and lasted until their spontaneous death.
Under tested experimental conditions, methyl alcohol and ethyl alcohol
were demonstrated to be carcinogenic for various organs and tissues.
They must also be considered multipotential carcinogenic agents.
In addition to causing other tumors, ethyl alcohol induced malignant
tumors of the oral cavity, tongue, and lips.
These sites have been shown to be target organs in man by
epidemiologic studies.

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).
[ So, the normal methanol level was 2.62 mg per liter,
and increasing that by 50% = 1.3 mg per liter to 3.88 mg per liter
caused hangover symptoms. The human body has about
5.6 liters blood, so adding 1.3 mg per liter gives an estimate
of 7.3 mg added methanol, as much as 4 oz diet soda.
Diet soda is about 200 mg aspartame per 12 oz can,
which is 22 mg (11% methanol), 1.83 mg methnol per ounce.
This suggests that alcohol drinkers are more sensitive to methanol
than the average diet soda drinker, some of whom find symptoms
from a third of a diet soda.]
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.]

Elevated nitric oxide/peroxynitrite theory of multiple chemical sensitivity:
central role of N-methyl-D-aspartate receptors
in the sensitivity mechanism. Pall ML.

The elevated nitric oxide/peroxynitrite and the neural sensitization
theories of multiple chemical sensitivity (MCS) are extended here
to propose a central mechanism for the exquisite sensitivity
to organic solvents apparently induced
by previous chemical exposure in MCS.
This mechanism is centered
on the activation of N-methyl-D-aspartate (NMDA) receptors
by organic solvents producing elevated nitric oxide and
peroxynitrite, leading in turn to increased stimulating of and
hypersensitivity of NMDA receptors.
In this way, organic solvent exposure may produce
progressive sensitivity to organic solvents.
Pesticides such as organophosphates and carbamates
may act via muscarinic stimulation to produce a similar biochemical
and sensitivity response.
Accessory mechanisms of sensitivity may involve
both increased blood-brain barrier permeability,
induced by peroxynitrite,
and cytochrome P450 inhibition by nitric oxide.
The NMDA hyperactivity/hypersensitivity and excessive nitric
oxide/peroxynitrite view of MCS provides answers
to many of the most puzzling aspects of MCS
while building on previous studies and views of this condition.

Prof. Pall describes processes by which an initial trigger exposure,
such as carbon monoxide or formaldehyde,
can generate hypersensitivity to many substances.
He himself had recovered from a sudden, debilitating attack of
multiple chemical sensitivity in June/July 1997.
