My Aspartame Experiment

Introduction by author Carol Guilford
“In any such study of even a few hundred test animals, it takes no more than a dozen or so of them to exhibit a particular lesion… to associate with the test agent, i.e., aspartame or its related chemicals.”
Dr. Adrian Gross, FDA toxicologist in a letter to Senator Howard Metzenbaum, Oct. 30, 1986.
When Victoria Inness-Brown contacted me about “explosive information” concerning aspartame (Equal,NutraSweet) the controversial, artificial, chemical sweetener, I didn’t know what to expect. Despite overwhelming scientific evidence of aspartame’s danger to human health (tires have been recalled for less) it remains in 6,000 food, drink and medicinal products.
A FEMALE RAT DEVELOPED A MAMMARY TUMOR SO LARGE SHE OFTEN USED IT AS A PILLOW

Who could imagine a private citizen would do an aspartame experiment with 108 rats for 2 years and 8 months?
The late Dr. Adrian Gross explained that rodent experiments are the means to find out what a particular substance will do to human beings.
Look at Victoria’s pictures of her animals that ingested the equivalent amount of aspartame (in human terms) of less than one diet coke a day, until their spontaneous death. Importantly, the control groups, those fed no aspartame were free from visible effects. (1)
The artificial sweetener, Aspartame, was approved by the FDA, in 1981. By the 1990’s, the FDA had a list of 92 symptoms reported to them by 10,000 consumers, a list revealed to the public under the Freedom of Information Act. (2)
Personally, I have read thousands of cases from aspartame victims, many who post on Yahoo’s Aspartame Victim Support Group list, but Victoria’s photographs, the first ever to be released from any study, give meaning to the hypothesis, “A picture is worth a thousand words.”
Following is Victoria’s gutsy account of why she did her experiment, the protocol she used to conduct it and the remarkable pictures of the rats. Victoria says--
I did my aspartame experiment because my family was addicted to diet soda. After researching the effects of aspartame, I strongly believed the artificial sweetener might one day lead to their illness and even early death.
Most influential in my research on the aspartame molecule was The Bressler Report. (3) Dr. Jerome Bressler, M.D., led an FDA task force to attempt to validate the authenticity of a study done by G.D. Searle, the pharmaceutical company that held the patent to the “sweetener.”
Dr. Bressler’s team did the Searle audit between April 25, 1977 and August 4, 1977 of study PT #988S73, a 115 Week Oral Tumorigenicity Study in the Rat. The rat study was supposedly done by Searle to examine the adverse effects of the crystalline form of aspartame’s breakdown from phenylalanine, 50% of the chemical’s composition to SC-19192, diketopiperazine (DKP).
Bressler’s force found irregularities in Searle’s experiment-- missing raw data, errors and discrepancies in available data, exclusions of animals, and animals that had masses removed and were then returned to the study.
One unreported tissue mass in Searle’s study measured 5.0 X 4.5 X 2.5 cm. Equivalent to 2 in. X 1.75 in. X 1.0 in. —a significant sized tumor that should be visible to the naked eye, hard to miss.
I was convinced I would see tumors and possibly other harmful effects to convince my family and friends to avoid aspartame.
MY EXPERIMENTAL SETUP

MY EXPERIMENTAL PROTOCOL
Summary of aspartame rat study protocol | |
Protocol parameter | Description |
Source of aspartame | NutraSweet packets. |
Form of aspartame | NutraSweet dissolved in drinking water, available 24 hours per day. |
Dosage | Two packets of NutraSweet per eight ounces of water (about 80 mg of aspartame per each eight ounces); about 34 mg/kg of aspartame for males; 45 mg/kg for females. |
Duration | Two years, eight months (about 138 weeks, where one month = about 4.3 weeks); until the spontaneous death of the animals. |
Rat strain | Bred from two males, two females, each from different varieties of PetCo rats, including the Sprague Dawley strain. Maintained a genetic mix throughout the breeding, avoided mating brothers and sisters, mothers and sons, fathers and daughters. |
Number of rats in study | Experimental group of 30 males, 30 females. Control group of 24 males, 24 females; a total of 108 rats. |
Type of feed | Kaytee’s Supreme Fortified Daily Blend for Rat & Mouse and Kaytee’s Supreme Fortified Daily Blend for Hamster & Gerbil from a local feed store. |
DIET PEPSI, ASPARTAME OR NUTRASWEET? 
Because my family members were addicted to diet soda, at first I wanted to put Diet Pepsi in my rat’s water bottles. That idea was short lived. After turning a filled bottle upside down and attaching it to a cage, the liquid immediately started flowing out—carbonation pressurizes the bottle—so diet Pepsi wouldn’t work. It was just as well, because the cost of the soda would have been prohibitive over the course of the experiment.
I did not want to mix dry NutraSweet with rat food for several reasons. First, I wanted to simulate the effects of diet soda—a liquid. Next, NutraSweet is sold as powdered crystals that are tiny compared to the grains and alfalfa pellets comprising the food I fed my rats. I knew the powder would fall to the bottom of the food bowls, allowing the rats to avoid it.
I also knew from personal experience it would be hard to calculate the dosage, because so much food ends up in the trays under their cages. Finally, aspartame crystals may clump, allowing rats to avoid them. In The Bressler Report, the FDA task force reported the rats learned to eat around the DKP crystals.
I decided to mix pure aspartame in their water. In an Internet search for an aspartame supplier, I found only food and beverage manufacturers are permitted to purchase aspartame. Dr. Ralph Walton, a respected researcher, in the mid-90’s, experienced the same problem. No aspartame for sale for his study. (4)
The National Institute of Health evaluates a packet of aspartame-based sweetener such as NutraSweet contains 40 mg of aspartame.
I decided on putting the NutraSweet in their drinking water, at the rate of two packets—a total of 80 mg of aspartame–per each 8 oz of water.
A 12-oz diet soda has about 180 mg of aspartame, 15 mg of aspartame per oz., the amount in approximately 4.5 packets of NutraSweet.
According to the industry-run Aspartame Information Center website, a conservative estimate of the maximum dose of aspartame for humans per day, the Acceptable Daily Intake (ADI), as set by the FDA, is 50 mg/kg, approximately twenty cans of 12-ounce diet soda for a 150 lb. adult and six 12-ounce cans for a 50-pound child. Tabletop sweetener ADI is 97 packets for an adult and 32 packets for a child.
The animals in my study weighed on the average of 1 pound for males and 0.66 pounds for females. The ADI for the males was 16.9 mg and for the females 13.5 mg
To put these numbers into perspective, the aspartame received by my rats daily, was equivalent to two-thirds the aspartame contained in 8-oz of diet soda.
My masters degree is in mathematics.
RAT STRAIN
Most studies are done on rats that are genetically identical. According to a friend who runs a rabbit and mouse lab for a local bio-tech company, “Some vendors sell strains of rats that have gone through 30 generations of brother and sister in-bred mating.”
This concept seemed counter-intuitive to me. How do these strains of rats represent the general population? In “Mean Genes”, Jay Phelan and Terry Burnhan write: “Almost all animals avoid mating with close relatives because it makes for bad babies. From mice to monkeys, animals are reluctant to have offspring with siblings.
I bought my rats at PetCo and bred them for my experiment. I purchased rats of different colors, to get a genetic verity. I also attempted to breed rats that were not brothers and sisters, to avoid in-breeding mutation.
I found most of the observable symptoms occurred during the last third of the rat’s life-span, illuminating the information that the adverse effects of aspartame are cumulative.
I chose to allow my rats to live out their natural lives. I honor them for their sacrifice and for showing the way for the rest of us.
I put NutraSweet in their water starting in March, 2002, and the last of them died in November 2004. The experiment lasted a total of two years, eight months.
Even though I had read the Bressler Report, I was struck by the number and size of the growths. Eleven females and one male developed tumors. That’s 37% of the females on aspartame.
During the audit of Searle’s DKP study, pathologist Dr. Charles H. Frith spent three days with the FDA task force to review 145 animals. Sufficient slides substantiated 73 female animals with grossly observed masses.
THREE ASPARTAME FEMALES WITH TUMORS

In 2005, Dr. Morando Soffritti of the European Foundation of Oncology, in Bologna, Italy completed an 8-year “mega-experiment” with1800 rats, to evaluate the potential carcinogenic effects of aspartame.
The results of the experiment showed a dose-related statistically significant increase of lymphomas and leukemias in female rats. This statistically significant increase was also observed at the dose level of 20 mg/Kg of body weight, a dose inferior to the accepted daily intake permitted by current regulations.
Results of Dr. Soffritti’s second long-term carcinogenicity bioassay on Aspartame …”not only confirm but also reinforce our first experimental demonstration (Belpoggi et al. 2006; Soffritti et al. 2005, 2006) of APM's multipotential carcinogenicity at a dose level close to the human ADI. Furthermore, the study demonstrates that when life-span exposure to APM (aspartame) begins during fetal life, its carcinogenic effects are increased.”
I was relieved to know to know Dr. Soffritti also let his rats live until spontaneous death because most cancers occur “in the last third of a person’s lifetime.”
There are no photographs from the Soffritti study. But one can surmise, they looked something like this.
THESE FEMALES IN MY MINI-EXPERIMENT APPEAR TO HAVE MAMMARY OR LYMPH TUMORS.






THIS MALE HAD A GROWTH ON THE RIGHT SIDE OF HIS FACE.


THE TUMOR GREW TO GIGANTIC PROPORTIONS AND APPEARED TO BE FILLED WITH NUMEROUS SMALLER TUMORS. THE TUMOUR BECAME ENTANGLED WITH HER RIGHT FORELEG CAUSING GREAT DIFFICULTY WHEN MOVING.

THIS LAST PHOTO OF THE SAME FEMALE, TAKEN AFTER DEATH, SHOWS THE SMALL TUMORS MORE PRONOUNCED ALONG WITH THE BLOOD VESSELS THAT FED THEM.

The fact that the European Union can discredit the Ramazzini Institute’s damning 8-year cancer study is because, as researcher Mark Gold, (holisticmed.com) points out, after extensive background checks-- the persons controlling our world-wide health have big-time ties to industry.
Endocrinologist, Dr. H. J. Roberts, M.D. writes in “Aspartame Disease: An Ignored Epidemic”, “The FDA initially received ocular complaints attributed to aspartame from 177 consumers (Dr. Linda Tollefson, personal communication, August 12, 1987).
Eye complaints, in the 1200 cases Dr. Roberts clinically observed for his book “were prominent”, including retinal detachment and in 27 cases, blindness occurred in one or both eyes. Other aspartame “reactors” reported tunnel vision, eye pain, jerking of the eyes, bright flashes, dry eyes, trouble with contact lenses and bleeding eyes.



“In 1991, I was diagnosed with an ‘incurable’ case of Grave's Disease, a fatal thyroid disorder, I never really had Grave's Disease but my doctors were convinced I did. I had aspartame poisoning with symptoms of 'textbook‘ Grave's Disease caused by aspartame saturating my foods.”
Dr. Janet Starr Hull
“Sweet Poison”: How The World's Most Popular Artificial Sweetener is Killing Us. New Horizon Press
One of the symptoms of Grave’s Disease is protruding eyes. This is a no-longer private e-mail from Dr. Hull to Carol Guilford.
“YES, I had protruding eyes, cystic acne, and my hair was falling out in clumps. I had gained 30 pounds, too. ALL that went away within a year from stopping all aspartame. I even had holes in my retina from the methanol, and those have closed up now. All backed up by my eye surgeon.”
If you go to Dr. Hull’s web site, sweetpoison.com, you will find her a beautiful-looking woman.



No observable eye disorders were found in my control group of 48 animals.
He did not live long after.


Torticollis is a condition that causes the neck to twist, involuntary to one side. The NSTA, the National Spasmodic Torticollis Association, describes torticollis as “Spasmodic Torticollis (ST), a painful and debilitating neurological disorder caused by a dysfunction of the brain.”

Note that his body is leaning toward his left side.
Unsteady gait is No. 61 on the FDA list of aspartame symptoms.

“Searle had submitted 13 tests in an attempt to establish that aspartame did not cause genetic damage but memos from public records show that FDA scientists who reviewed the tests found serious deficiencies in all of them.”

THE LARGE TAN MALE RAT IN THE CENTER BELOW WAS THE SAME AGE AS HIS STUNTED MALE AND FEMALE COUSINS. THE SMALLER RATS GREW TO ABOUT HALF THE AVERAGE WEIGHT OF THEIR COUSINS.

Changes in skin in No. 65 on the FDA list and No. 66 is change in hair or nails. These shots are graphic, indeed. No rats in the control group showed skin problems.

A SKIN LESION ON AN ASPARTAME MALE



IS ASPARTAME A HAZARDOUS CHEMICAL?
OSHA, the Occupational Safety and Health Administration classifies methanol, formaldehyde and formic acid, components of aspartame as hazardous.
Aspartame is a very sophisticated, clever drug. So, first off, let me point out that this sophisticated, clever drug could never have been “discovered” accidentally.
Incidentally, James M. Schlatter, the scientist who, working on an ulcer drug licked his finger to find the sweet chemical NutraSweet has never been questioned.
PHENYLALANINE, 50% of the aspartame molecule is isolated from the chain of amino acids with which it exists in nature. Isolated phenylalanine, neurosurgeon Dr. Russell Blaylock, M.D. tells us crosses the blood brain barrier to interfere and kill the neurotransmitters of the brain by “exciting them to death.” (“Excitotoxins: The Taste That Kills”)
In 1987, Dr. Louis J. Elsas, then Professor of Pediatrics and Director of the Division of Medical Genetics at Emory University testified at the hearing before the United States Senate Committee on Labor and Human Resources, concerning “NUTRASWEET”—HEALTH AND SAFETY CONCERNS.”
Dr. Elsas told the Senators, “In the developing fetus such a rise in maternal blood phenylalanine could be magnified four to six fold by the concentrative efforts of the placental and fetal blood brain barrier and this concentration kills such cells in tissue culture. The effect of such an increased fetal brain concentrations in vivo would probably be much more subtle and expressed as mental retardation, microcephaly, or potential certain birth defects.”
Does autism ring a bell? When Dr. Elsas told the senate this significant fact about phenylalanine, in 1987, infant autism rates were 1 in 1500, today they are 1 in 150 and rising.
How many of us ever heard of Alzheimer’s, in 1980? The rates have doubled since aspartame was approved; a conservative statistic is 5 million in the US have the disease.
PHENYLALANINE converts to DKP, diketopiperazine, a tumor agent. The suspicious study of DKP by Searle Pharmaceuticals prompted the FDA to audit the experiment, the results of which are documented in the Bressler Report.
ASPARTIC ACID is 40% of the aspartame molecule. Dr. Madelon Price, in 1998 was Professor of Neurobiology at Washington University, in St. Louis, Missouri told her students: “Aspartic acid (aspartate) has been known to be a neurotoxin for 30 years. (now 40 years) Rodents that have ingested too much aspartame as infants are stunted as adults, obese and have sexual and reproductive dysfunctions. (7)
At the same lecture to her students that day, someone asked Dr. Price whether the phenylalanine in neotame, the aspartame clone, approved by the FDA was the same as the phenylalanine in aspartame. Dr. Price answered, it was. Neotame is now in the food supply, unlabeled, without a PKU warning for those who cannot metabolize phenylalanine. “Ah, says industry… but there’s such a small amount of phenylalanine in neotame, it doesn’t count.”
Wait a minute. Dr. Price explains, “Aspartate (aspartame) is additive in its effects with glutamate and other excitotoxins. In other words, a subtoxic dose of aspartame added to a subtoxic dose of glutamate (MSG) may add up to a toxic dose. Unfortunately it is hard to find food that does not contain added glutamate, and for some categories of food it does not have to be listed on the label.
METHANOL is 10% of the aspartame molecule. Methanol (wood alcohol) is a known poison and addictive, too. Doesn’t everyone knows someone who carries a diet Coke around all day?
The aspartame industry claims there is more methanol in a glass of orange juice than in aspartame products, but in a natural product, such as orange juice, the poisonous wood alcohol has the antidote for methanol inherently in it-- ethanol.
“Formaldehyde is a highly reactive small molecule which strongly binds to proteins and nucleic acids forming adducts which are difficult to eliminate through the normal metabolism pathways… 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. “
2. Activist Betty Martini has a receipt from the Dept. of Health and Human Services for her request of the aspartame “report.” The cost was $42.30. The letter is dated June 6, 1995 http://www.presidiotex.com/92symptoms
4. Dr. Ralph Walton compiled a list of all controlled human and animal studies looking for the effects of aspartame. Out of 90 independently-funded studies, 83 of them found one or more problems caused by aspartame. But out of the 74 studies funded by the aspartame industry (e.g., Monsanto, G.D. Searle, etc). every single one of them claimed that no problems were found.
5. Dr. Sandra Cabot (“The Liver Cleansing Diet”) in a position paper on aspartame explains the liver is so busy detoxing the poisons from aspartame, it cannot properly metabolize fat.
Dr. Blaylock writes, in an article for Nurse World Magazine… “dozens of independent laboratories have confirmed the connection between gross obesity and exposure to MSG early in life. More recent studies have also found it induces type 2 diabetes. “One of the most frightening connections is with sudden cardiac death. It is known that the heart’s electrical conduction system contains a number of glutamate receptors, as does the heart muscle itself. If these glutamate receptors are overstimulated, fatal arrhythmias can result.” Change in heart rate is No. 15 on the FDA list of aspartame symptoms.
6. Everything you ever wanted to know about the methanol in aspartame is in Dr. Monte’s letter of January, 2006. Author, columnist David L. Dewey has posted the letter at http://www.dldewey.com/monte.htm David’s concise article Aspartame - Sweetness Disguised as Disease or Death is at http://www.dldewey.com/aspar.htm
7. Dr. Price worked with Dr. John Olney, who in 1969 found aspartic acid caused nerve damage in the brains of mice. It was Dr. Olney who discovered that aspartame and MSG could kill brain cells by “exciting” them to death, hence the name “excitotoxin.”
In 1996, Dr. Olney showed the link between aspartame and brain cancer, up 10% after aspartame had been on the market for 3 years and one year after its inclusion in diet sodas.
Despite an airing on “60 Minutes”, Dr. Olney was media-blitzed by industrial power, in the same manner as Dr. Soffritti is being dismissed today, ten years later.




What a waste of innocent
What a waste of innocent life and what a cruel existence you imposed on these animals...just to prove something that we already know, that can be proven or disproven according to your bias. All life is valuable to itself and equally so, to God. Remember that as a scientist you are not God, and should demonstrate regard for all forms of life, regardless of our ignorance to its complexities.
vivisectionist propaganda
What a shame that this site has felt the need to help the pharmaceutical/vivisection industry in its spread of vivisectionist propaganda - as if these 'experiments' had anything to tell us about how aspartame affects human beings.
Even common food ingredients - such as sugar or salt - will cause these type of effects in laboratory animals when given in sufficient quantities.
Almost worse is the seemingly approval of a 'DIY' type of vivisection, using animals purchased from a pet shop.
I had expected better here. My link to this site has thus been removed.
Yes I did have my concerns
Yes I did have my concerns about posting this article (Because I have become a vegetarian within the last 6 months and I do think vivisection is wrong), but the experiment has been done and I feel the dangers and the message of Aspartame needs to be highlighted. If you have evidence that disproves the dangers of Aspartame please provide? All you have done is attack the vivisection but what do you think of Aspartame and the damage it's doing to our kids?
vivisection and aspartame
No, of course I do not have "evidence that disproves the dangers of Aspartame", and yes I am "attacking the vivisection." The point I am making is that the whole vivisectionist method of research is totally pointless; anything can be proven to be 'safe' or ‘harmful' depending upon the species of animal used; witness the wholesale testing on animals in the past by the sugar/artificial sweeteners industries, both eager to 'prove' that their products are safe, and their opposition's hazardous to health - the animals being the innocent scapegoats in a war of industrial concerns.
To scientifically demolish the whole vivisection method here would take much more space than that available; besides, the evidence being easily available for those interested enough to find out.
However, people must be made aware that animals are used by the chemical and pharmaceutical industries to provide their products with a clean bill of health; witness the profusion of drugs that have reached the market place and consequently been found hazardous to health - as well as the 100,000 US citizens killed each year by prescribed drugs.
The point is, I do not know whether aspartame is safe for humans or not - although personally I err on the side of caution and avoid it like the plague - but the simple fact of the matter is that only human studies, truly relevant to human beings, will provide the answer. Whether or not the animal studies eventually prove to correlate with the human studies will only be known after the event, and this is the crux of the matter - animal tests are meaningless until the effects of the drug/chemical in question on human beings is known, anything until then being sheer speculation - not something any genuine scientist would recommend as a method of evaluating the safety and effectiveness of chemicals intended for human use.

What a wonderful experiment
I'm a cancer survivor and applaud your efforts to alert the world to the dangers of aspartame. I'm particularly grateful because my granddaughter (a fifth grader) was trying to understand what the controversy was all about. Your wonderful experiment makes it so visual. It leaves no doubt why aspartame should be avoided by all. What a terrible epidemic industry has foisted on the world. Thank you, thank you thank you!
