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 is, by far, the most dangerous substance on the market
that is added to foods. 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: 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) 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) SUMMARY OF HOW ASPARTATE (AND GLUTAMATE) CAUSE DAMAGE 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 mimmicks 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) 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 excititory amino acid damage. Blaylock is one of many scientists and physicians who are concerned about excititory 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.) Also included is Francis J. Waickman, M.D., a recipient of the Rinkel and Forman Awards, and Board certified in Pediatrics, Allergy, and Immunology. Other concerned scientists include: John R. Hain, M.D., Board Certified Forensic Pathologist, and H.J. Roberts, M.D., FACP, FCCP, Diabetic Specialist, and selected by a national medical publication as "The Best Doctor in the US" John Samuels is concerned, also. He compiled a list of scientific research sufficient to show the dangers of ingesting excess free glutamic and aspartic acid. And there are many more who can be added to this long list. PHENYLALANINE (50% OF ASPARTAME) One account of a case of extremely high phenylalanine levels caused by aspartame was recently published the the "Wednesday Journal" in an article entitled "An Aspartame Nightmare." John Cook began drinking 6 to 8 diet drinks every day. His symptoms started out as memory loss and frequent headaches. He began to crave more aspartame-sweetened drinks. His condition deteriorated so much that he experienced wide mood swings and violent rages. Even though he did not suffer from PKU, a blood test revealed a phenylalanine level of 80 mg/dl. He also showed abnormal brain function and brain damage. After he kicked his aspartame habit, his symptoms improved dramatically.(8) As Blaylock points out in his book, early studies measuring phenylalanine buildup in the brain were flawed. Investigators who measured specific brain regions and not the average throughout the brain notice significant rises in phenylalanine levels. Specifically the hypothalamus, medulla oblongata, and corpus striatum areas of the brain had the largest increases in phenylalanine. Blaylock goes on to point out that excessive buildup of phenylalanine in the brain can cause schizophrenia or make one more susceptible to seizures. Therefore, long-term, excessive use of aspartame may provided a boost to sales of seratonin reuptake inhibitors such as Prozac and drugs to control schizophrenia and seizures. METHANOL (AKA WOOD ALCOHOL/POISON) (10% OF ASPARTAME) The absorption of methanol into the body is sped up considerably when free methanol is ingested. Free methanol is created from aspartame when it is heated to above 86 Fahrenheit (30 Centigrade). This would occur when aspartame-containing product is improperly stored or when it is heated (e.g., as part of a "food" product such as Jello). Methanol breaks down into formic acid and formaldehyde in the body. Formaldehyde is a deadly neurotoxin. An EPA assessment of methanol states that methanol "is considered a cumulative poison due to the low rate of excretion once it is absorbed. In the body, methanol is oxidized to formaldehyde and formic acid; both of these metabolites are toxic." The recommend a limit of consumption of 7.8 mg/day. A one-liter (approx. 1 quart) aspartame-sweetened beverage contains about 56 mg of methanol. Heavy users of aspartame-containing products consume as much as 250 mg of methanol daily or 32 times the EPA limit.(9) Symptoms from methanol poisoning include headaches, ear buzzing, dizziness, nausea, gastrointestinal disturbances, weakness, vertigo, chills, memory lapses, numbness and shooting pains in the extremities, behavioral disturbances, and neuritis. The most well knowm problems from methanol poisoning are vision problems including misty vision, progressive contraction of visual fields, blurring of vision, obscuration of vision, retinal damage, and blindness. Formaldehye is a known carcinogen, causes retinal damage, interferes with DNA replication, causes birth defects.(10) Due to the lack of a couple of key enzymes, humans are many times more sensitive to the toxic effects of methanol than animals. Therefore, tests of aspartame or methanol on animals do not accurately reflect the danger for humans. As pointed out by Dr Woodrow C. Monte, Director of the Food Science and Nutrition Laboratory at Arizona State University, "There are no human or mammalian studies to evaluate the possible mutagenic, teratogenic, or carcinogenic effects of chronic administration of methyl alcohol."(11) He was so concerned about the unresolved safety issues that he filed suit with the FDA requesting a hearing to address these issues. He asked the FDA to "slow down on this soft drink issue long enough to answer some of the important questions. It's not fair that you are leaving the full burden of proof on the few of us who are concerned and have such limited resources. You must remember that you are the American public's last defense. Once you allow usage (of aspartame) there is literally nothing I or my colleagues can do to reverse the course. Aspartame will then join saccharin, the sulfiting agents, and God knows how many other questionable compounds enjoined to insult the human constitution with governmental approval."(10) Shortly thereafter, the Commissioner of the FDA, Arthur Hull Hayes, Jr., approved the use of aspartame in carbonated beverages, he then left for a position with G.D. Searle's Public Relations firm.(11) It has been pointed out that some fruit juices and alcoholic beverages contain small amounts of methanol. It is important to remember, however, that methanol never appears alone. In every case, ethanol is present, usually in much higher amounts. Ethanol is an antidote for methanol toxicity in humans.(9) The troops of Desert Storm were "treated" to large amounts of aspartame-sweetened beverages which had been heated to over 86°F. in the Saudi Arabian sun. Many of them returned home with numerous disorders similar to what has been seen in persons who have been chemically poisoned by formaldehyde. The free methanol in the beverages may have been a contributing factor in these illnesses. Other breakdown products of aspartame such as DKP (discussed below) may also have been a factor. In a 1993 act that can only be described as "unconscionable," the FDA approved aspartame as an ingredient in numerous food items that would always be heated to above 86°F (30°C). DIKETOPIPERAZINE (DKP) G.D. Searle conducted animal experiments on the safety of DKP. The FDA found numerous experimental errors occured, including "clerical errors, mixed-up animals, animals not getting drugs they were supposed to get, pathological specimens lost because of improper handling," and many other errors.(12) These sloppy laboratory procedures may explain why both the test and control animals had sixteen times more brain tumors than would be expected in experiments of this length. In an ironic twist, shortly after these experimental errors were discovered, the FDA used guidelines recommened by G.D. Searle to devlop the Industry-wide FDA standards for Good Laboratory Practies.(11) DKP has also been implicated as a cause of uterine polyps and changes in blood cholesterol by FDA Toxicologist Dr Jacqueline Verrett in her testimony before the US Senate.(13) AILMENTS RESULTING FROM ASPARTAME There is an enormous population of people who are suffering from symtpoms contributed to by aspartame, yet they have no idea why herbs or drugs are not helping relieve their problems. There are other users of aspartame who appear not to be suffering immediate reactions to aspartame. But even these individuals are susceptible to the long-term damage caused by excitatory amino acids, phenylalanine, methanol, and DKP. A few of the many disorders that are of particular concern to me include the following. Birth Defects. In the book, While Waiting: A Prenatal Guidebook by George R. Verrilli, M.D. and Anne Marie Mueser, it is stated that aspartame is suspected of causing brain damage in sensitive individuals. A fetus may be at risk for these effects. Some researchers have suggested that high doses of aspartame may be associated with problems ranging from dizziness and subtle brain changes to mental retardation. Cancer (Brain Cancer). In the mid-1970s it was discovered that the manufacturer of aspartame falsified studies in several ways. One of the techniques used was to cut tumors out of test animals and put them back in the study. Another technique used to falsify the studies was to list animals that had actually died as surviving the study. Thus, the data on brain tumors was likely worse than discussed above. In addition, a former employee of the manufacturer of aspartame, Raymond Schroeder told the FDA on July 13, 1977 that the particles of DKP were so large that the rats could dicriminate between the DKP and their normal diet.(12) 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.(17) In his book, Aspartame (NutraSweet). Is it Safe?, Roberts gives evidence that aspartame can cause a particularly dangerous form of cancer - primary lymphoma of the brain. Diabetes. In a statement concerning the use of products containing aspartain
by persons with diabetes and hypoglycemia, Roberts says:
"Unfortunately, many patients in my practice, and others seen in
consultation, developed serious metabolic, neurologic and other
complications that could be specifically attributed to using
aspartame products. This was evidenced by: "Dramatic improvement of such features after avoiding aspartame, and the prompt predictable recurrence of these problems when the patient resumed aspartame products, knowingly or inadvertently." Roberts goes on to say: Blaylock stated that excitotoxins such as that found in aspartame can precipitate diabetes in persons who are genetically susceptible to the disease.(5) Emotional Disorders. The study showed a large increase in serious symptoms for persons taking aspartame. Since some of the symptoms were so serious, the Institutional Review Board had to stop the study. Three of the participants had said that they had been "poisoned" by aspartame. Walton concludes that "individuals with mood disorders are particularly sensitive to this artificial sweetener; its use in this population should be discouraged."(18) Aware that the experiment could not be repeated because of the danger to the test subjects, Walton was recently quoted as saying, "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."(19) There are numerous reported cases of low brain serotonin levels, depression and other emotional disorders that have been linked to aspartame and often are relieved by stopping the intake of aspartame. Researchers have pointed out that increasing in phenylalanine levels in the brain, which can and does occur in persons without PKU, leads to a decreased level of the neurotransmitter, serotonin, which leads to a variety of emotional disorders. Dr William M. Pardridge of UCLA testified before the US Senate that a youth drinking four 16-ounce bottles of diet soda per day leads to an enormous increase in the phenylalanine level. Epilepsy/Seizures. "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." Both the Air Force's magazine Flying Safety and the Navy's magazine, Navy Physiology published articles warning about the many dangers of aspartame including the cumlative deliterious effects of methanol and the greater likelihood of birth defects. The articles note that the ingestion of aspartame can make pilots more susceptible to seizures and vertigo. Twenty articles sounding warnings about ingesting aspartame while flying have also appeared in the National Business Aircraft Association Digest (NBAA Digest 1993), Aviation Medical Bulletin (1988), The Aviation Consumer (1988), Canadian General Aviation News (1990), Pacific Flyer (1988), General Aviation News (1989), Aviation Safety Digest (1989), and Plane & Pilot (1990) and a paper warning about aspartame was presented at the 57th Annual Meeting of the Aerospace Medical Association (Gaffney 1986). Recently, a hotline was set up for pilots suffering from acute reactions to aspartame ingestion. Over 600 pilots have reported symptoms including some who have reported suffering grand mal seizures in the cockpit due to aspartame.(21) One of the original studies on aspartame was performed in 1969 by an independent scientist, Dr Harry Waisman. He studied the effects of aspartame on infant primates. Out of the seven infant monkeys, one died after 300 days and five others had grand mal seizures. Of course, these negative findings were not submitted to the FDA during the approval process.(22) Why don't we hear about these things? The reason many people do not hear about serious reactions to
aspartame is twofold: 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: 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: Revolving doors 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.(25) Many other "independent" organizations and researchers receive large sums of money from the manufacturers of aspartame. The American Diabetes Association has received a large amount of money from Nutrasweet, including money to run a cooking school in Chicago (presumably to teach diabetes how to use Nutrasweet in their cooking). A researcher in New England who has pointed out the dangers of aspartame in the past is now a Monsanto consultant. Another researcher in the Southeastern US had testified about the dangers of aspartame on fetuses. An investigative reporter has discovered that he was told to keep his mouth shut to avoid causing the loss of a large grant from a diet cola manufacturer in the NutraSweet Association. What is the FDA doing to protect the consumer from the dangers of aspartame? Less than nothing. In 1992, the FDA approved aspartame for use in malt beverages, breakfast cereals, and refrigerated puddings and fillings. In 1993 the FDA approved aspartame for use in hard and soft candies, non-alcoholic favored beverages, tea beverages, fruit juices and concentrates, baked goods and baking mixes, and frostings, toppings and fillings for baked goods. In 1991, the FDA banned the importation of stevia. The powder of the leaf has been used for hundreds of years as an alternative sweetner. It is used widely in Japan with no adverse effects. Scientists involved in reviewing stevia have declared it to be safe for human consumption - something which has been well known in many parts of the world where it is not banned. Everyone that I have spoken with in regards to this issue believes that stevia was banned to keep the product from taking hold in the US and cutting into sales of aspartame.(26) What is the US Congress doing to protect the consumer from the dangers of aspartame? Nothing. What is the US Administration (President) doing to protect the consumer from the dangers of aspartame? Nothing. Aspartame consumption is not only a problem in the US. It is being sold in over 70 countries throughout the world. ASPARTAME CAN BE FOUND IN: I have been told that aspartame has been found in products where it is not listed on the label. One must be particular careful of pharmaceuticals and supplements. I have been informed that even some supplements made by well-known supplement manufacturers such as Twinlabs contain aspartame. The information I have related above is just the tip of the iceberg as far as damaging information about aspartame. In order for the reader to find out more, I have included some resources below.
