ASPARTAME: WHAT YOU DON'T KNOW CAN HURT YOU
ASPARTAME IS, BY FAR, THE MOST DANGEROUS SUBSTANCE ON THE MARKET THAT IS ADDED TO FOODS
by Dr. Joseph Mercola

Aspartame is the technical name for the brand names, NutraSweet, Equal, Spoonful, and Equal-Measure. Aspartame was discovered by accident in 1965, when James Schlatter, a chemist of G.D. Searle Company was testing an anti-ulcer drug. Aspartame was approved for dry goods in 1981 and for carbonated beverages in 1983. It was originally approved for dry goods on July 26, 1974, but objections filed by neuroscience researcher Dr John W. Olney and Consumer attorney James Turner in August 1974 as well as investigations of G.D. Searle's research practices caused the US Food and Drug Administration (FDA) to put approval of aspartame on hold (December 5, 1974). In 1985, Monsanto purchased G.D. Searle and made Searle Pharmaceuticals and The NutraSweet Company separate subsidiaries.

Aspartame accounts for over 75 percent of the adverse reactions to food additives reported to the US Food and Drug Administration (FDA). Many of these reactions are very serious including seizures and death as recently disclosed in a February 1994 Department of Health and Human Services report.(1) A few of the 90 different documented symptoms listed in the report as being caused by aspartame include: Headaches/migraines, dizziness, seizures, nausea, numbness, muscle spasms, weight gain, rashes, depression, fatigue, irritability, tachycardia, insomnia, vision problems, hearing loss, heart palpitations, breathing difficulties, anxiety attacks, slurred speech, loss of taste, tinnitus, vertigo, memory loss, and joint pain.

According to researchers and physicians studying the adverse effects of aspartame, the following chronic illnesses can be triggered or worsened by ingesting of aspartame:(2) Brain tumors, multiple sclerosis, epilepsy, chronic fatigue syndrome, parkinson's disease, alzheimer's, mental retardation, lymphoma, birth defects, fibromyalgia, and diabetes.

Aspartame is made up of three chemicals: Aspartic acid, phenylalanine, and methanol. The book, Prescription for Nutritional Healing, by James and Phyllis Balch, lists aspartame under the category of "chemical poison." As you shall see, that is exactly what it is.

ASPARTIC ACID (40% OF ASPARTAME) Dr Russell L. Blaylock, a professor of Neurosurgery at the Medical University of Mississippi, recently published a book thoroughly detailing the damage that is caused by the ingestion of excessive aspartic acid from aspartame. [Ninety nine percent of monosodium glutamate 9MSG) is glutamic acid. The damage it causes is also documented in Blaylock's book.] Blaylock makes use of almost 500 scientific references to show how excess free excitatory amino acids such as aspartic acid and glutamic acid in our food supply are causing serious chronic neurological disorders and a myriad of other acute symptoms.(3)

SUMMARY OF HOW ASPARTATE (AND GLUTAMATE) CAUSE DAMAGE Aspartate and glutamate act as neurotransmitters in the brain by facilitating the transmission of information from neuron to neuron. Too much aspartate or glutamate in the brain kills certain neurons by allowing the influx of too much calcium into the cells. This influx triggers excessive amounts of free radicals which kill the cells. The neural cell damage that can be caused by excessive aspartate and glutamate is why they are referred to as "excitotoxins." They "excite" or stimulate the neural cells to death.

Aspartic acid is an amino acid. Taken in its free form (unbound to proteins) it significantly raises the blood plasma level of aspartate and glutamate. The excess aspartate and glutamate in the blood plasma shortly after ingesting aspartame or products with free glutamic acid (glutamate precursor) leads to a high level of those neurotransmitters in certain areas of the brain.

The blood brain barrier (BBB) which normally protects the brain from excess glutamate and aspartate as well as toxins 1) is not fully developed during childhood, 2) does not fully protect all areas of the brain, 3) is damaged by numerous chronic and acute conditions, and 4) allows seepage of excess glutamate and aspartate into the brain even when intact.

The excess glutamate and aspartate slowly begin to destroy neurons. The large majority (75%+) of neural cells in a particular area of the brain are killed before any clinical symptoms of a chronic illness are noticed. A few of the many chronic illnesses that have been shown to be contributed to by long-term exposure excitatory amino acid damage include:

Multiple sclerosis (MS), ALS, memory loss, hormonal problems, hearing loss, epilepsy, Alzheimer's disease, Parkinson's disease, hypoglycemia, AIDS dementia, brain lessions, and neuroendocrine disorders.

The risk to infants, children, pregnant women, the elderly, and persons with certain chronic health problems from excitotoxins are great. Even the Federation of American Societies For Experimental Biology (FASEB), which usually understates problems and mimics the FDA party-line, recently stated in a review that "it is prudent to avoid the use of dietary supplements of L-glutamic acid by pregnant women, infants, and children. The Existence of evidence of potential endocrine responses, i.e., elevated cortisol and prolactin, and differential responses between males and females, would also suggest a neuroendocrine link and that supplemental L-glutamic acid should be avoided by women of childbearing age and individuals with affective disorders."(4) Aspartic acid from aspartame has the same deleterious effects on the body as glutamic acid.

The exact mechanism of acute reactions to excess free glutamate and aspartate is currently being debated. As reported to the FDA, those reactions include:(5) Headaches/migraines, nausea, abdominal pains, fatigue (blocks sufficient glucose entry into brain), sleep problems, vision problems, anxiety attacks, depression, and asthma/chest tightness.

One common complaint of persons suffering from the effect of aspartame is memory loss. Ironically, in 1987, G.D. Searle, the manufacturer of aspartame, undertook a search for a drug to combat memory loss caused by excitatory amino acid damage. Blaylock is one of many scientists and physicians who are concerned about excitatory amino acid damage caused by ingestion of aspartame and MSG. A few of the many experts who have spoken out against the damage being caused by aspartate and glutamate include Adrienne Samuels, Ph.D., an experimental psychologist specializing in research design. Another is Olney, a professor in the department of psychiatry, School of Medicine, Washington University, a neuroscientist and researcher, and one of the world's foremost authorities on excitotoxins. (He informed Searle in 1971 that aspartic acid caused holes in the brain of mice.)

Other Information on Aspartame:

Weight Loss
The American Cancer Society confirmed that users of artificial sweeteners gained more weight than those who didn’t use the products. (American Cancer Society six-year study which tracked 80,000 women.)

Cancerous Brain Tumors
In a two-year study sponsored by the manufacturer of aspartame, twelve of the 320 rats fed a normal diet and aspartame developed brain tumors while none of the control rats had tumors. Five of the twelve tumors were in rats given a LOW dose of aspartame.(Studies by MIT neuroscientist Richard Wurtman)

It is interesting to note that the incidence of brain tumors in persons over 65 years of age has increase 67% between the years 1973 and 1990. Brain tumors in all age groups has jumped 10%. The greatest increase has come during the years 1985-1987.(The Effects of Aspartame)

Diabetes
The American Diabetes Association (ADA) is actually recommending aspartame to persons with diabetes. However, according to research conducted by H.J. Roberts, a diabetes specialist, a member of the ADA, and an authority on artificial sweetners, aspartame: 1) Actually leads to the precipitation of clinical diabetes. 2) Causes poorer diabetic control in diebetics on insulin or oral drugs. 3) Leads to the aggravation of diabetic complications such as retinopathy, cataracts, neuropathy and gastroparesis. 4) Causes convulsions.

Emotional Disorders
A double blind study of the effects of aspartame on persons with mood disorders conducted by Dr Ralph G. Walton showed a large increase in serious symptoms for persons taking aspartame. However, the study was halted by the Institutional Review Board because some of the subjects were experiencing severe symptoms. Dr. Walton stated, "individuals with mood disorders are particularly sensitive to this artificial sweetener; its use in this population should be discouraged." Since such a dangerous experiment can never be repeated on humans, Dr. Walton stated, "I know it causes seizures. I'm convinced also that it definitely causes behavioral changes. I'm very angry that this substance is on the market. I personally question the reliability and validity of any studies funded by the NutraSweet Company." (Steinman, "Diet for a Poisoned Planet", p.190. University of California study.)

Overall Analyses
At MIT, 80 people who had suffered seizures after ingesting aspartame were surveyed. Community Nutrition Institute concluded the following about the survey: "These 80 cases meet the FDA's own definition of an imminent hazard to the public health, which requires the FDA to expeditiously remove a product from the market."(www.mercola.com/article/aspartame/ailments.htm)

FDA Approval
Erik Millstone, a researcher at the Science Policy Research Unit of Sussex University has compiled thousands of pages of evidence, some of which have been obtained using the freedom of information act 23, showing: 1. Laboratory tests were faked and dangers were concealed. 2. Tumors were removed from animals and animals that had died were "restored to life" in laboratory records. 3. False and misleading statements were made to the FDA. 4. The two US Attorneys given the task of bringing fraud charges against the aspartame manufacturer took positions with the manufacturer's law firm, letting the statute of limitations run out. 5. The Commissioner of the FDA overruled the objections of the FDA's own scientific board of inquiry. Shortly after that decision, he took a position with Burson-Marsteller, the firm in charge of public relations for G.D. Searle. A Public Board of Inquiry (PBOI) was conducted in 1980. There were three scientists who reviewed the objections of Olney and Turner to the approval of aspartame. They voted unanimously against aspartame's approval. The FDA Commissioner, Dr Arthur Hull Hayes, Jr. then created a 5-person Scientific Commission to review the PBOI findings. After it became clear that the Commission would uphold the PBOI's decision by a vote of 3 to 2, another person was added to the Commission, creating a deadlocked vote. This allowed the FDA Commissioner to break the deadlock and approve aspartame for dry goods in 1981. Dr Jacqueline Verrett, the Senior Scientist in an FDA Bureau of Foods review team created in August 1977 to review the Bressler Report (a report that detailed G.D. Searle's abuses during the pre-approval testing) said: "It was pretty obvious that somewhere along the line, the bureau officials were working up to a whitewash." In 1987, Verrett testified before the US Senate stating that the experiments conducted by Searle were a "disaster." She stated that her team was instructed not to comment on or be concerned with the overall validity of the studies. She stated that questions about birth defects have not been answered. She continued her testimony by discussing the fact that DKP has been shown to increase uterine polyps and change blood cholesterol and that increasing the temperature of the product leads to an increase in production of DKP.

It is important to realize that this type of revolving-door activity has been going on for decades. The Townsend Letter for Doctors (11/92) reported on a study revealing that 37 of 49 top FDA officials who left the FDA took positions with companies they had regulated. They also reported that over 150 FDA officials owned stock in drug companies they were assigned to manage. Many organizations and universities receive large sums of money from companies connected to the NutraSweet Association, a group of companies promoting the use of aspartame. In January 1993, the American Dietetic Association received a US$75,000 grant from the NutraSweet Company. The American Dietetic Association has stated that the NutraSweet Company writes their "Facts" sheets. (www.mercola.com/article/aspartame/ailments.htm)
