Here are some illnesses that have been linked with MSG:
MSG and ADD
In the December 2003 issue the Journal of Neuropsychiatry and Clinical Neurosciences, it was reported that researchers found increased levels of glutamate in the brains of children who suffered from Attention Deficit Hyperactivity Disorder (ADHD). In those same children, levels of Gamma Amino Butyric Acid (GABA), were decreased.
It is interesting to note that the body converts glutamate into GABA using an enzyme called Glutamic Acid Decarboxylase (GAD). This imbalance of the two neurotransmitters would suggest that the body is not converting glutamate properly.
GAD is mentioned elsewhere on this site. Children suffering from Type I diabetes often have an immune system which attacks GAD. It would seem that Type I diabetics may also be at higher risk from ADHD then, due to the body's difficulty converting Glutamate to GABA.
MSG and Alcoholism
MSG and Allergy
MSG Sensitivity: Unlike food allergies which affect only certain individuals (only 2% - 5% of the population), and involve an antibody response of the immune system, food sensitivities affect many more people. You can be allergic to carrots and have an immune response to them, and someone else may have absolutely no immune response at all. Sensitivities are a different matter. There are no antibodies involved and in the case of MSG, the free glutamic acid in it acts in us all in the same way. It is a neurotransmitter - it causes nerve cells to fire. The reason MSG is used by food companies is because in the average human it stimulates the nerve cells in your mouth, as well as the brain. It targets the centers of hunger and taste and smell. If it only worked in 2% of the population, there wouldn't be any money in it. It is basically a drug like alcohol or caffeine. However, the sensitivity response of any individual is simply a matter of degree.
MSG and the Immune System: Unfortunately, MSG also may affect the allergy response as well although it may not initiate it. According to new research from Johns Hopkins, the immune system is disturbed by nervous system over-stimulation. This is a problem because MSG is a nervous system excitatory neurotransmitter. Glutamate triggers nerve cells to fire. See the following link for info regarding this latest research:
MSG and Asthma
MSG and Autism
We honestly don't understand how public health policy "experts" can say that vaccines have nothing to do with seizures suffered by many children after receiving vaccines with MSG in them. The fact that 30% of children with autism also suffer from epilepsy should be a red flag. http://www.epilepsyfoundation.org/epilepsyusa/yebeh/upload/autismandepilepsy.pdf
The fact that many parents with children who regressed after vaccination report seizures shortly after vaccination should be enough to spur thorough investigation.
MSG and Blindness
MSG and Cancer
In this paper from the National Academy of Sciences, glutamate antagonists slow tumor growth.
This article discusses the use of glutamate antagonists or blockers in the treatment of cancer. These antagonists apparently also inhibit cancer cell migration and so may be useful in preventing cells from proliferating throughout the body. One has to ask the nagging question, then - If blocking glutamate can cause cancer cells to die and stop migrating, shouldn't cancer patients stop eating MSG and aspartame? Unfortunately, patients suffering from cancer are rarely, if ever told this information.

Protein powders contain glutamic acid, which, invariably, will be processed free glutamic acid (MSG). Individual amino acids are not always listed on labels of protein powders.
At the present time there is an FDA requirement to include the protein source when listing hydrolyzed protein products on labels of processed foods. Examples are hydrolyzed soy protein, hydrolyzed wheat protein, hydrolyzed pea protein, hydrolyzed whey protein, hydrolyzed, corn protein. If a tomato, for example, were whole, it would be identified as a tomato. Calling an ingredient tomato protein indicates that the tomato has been hydrolyzed, at least in part, and that processed free glutamic acid (MSG) is present.
Disodium guanylate and disodium inosinate are relatively expensive food additives that work synergistically with inexpensive MSG. Their use suggests that the product has MSG in it. They would probably not be used as food additives if there were no MSG present.
MSG reactions have been reported from soaps, shampoos, hair conditioners, and cosmetics, where MSG is hidden in ingredients with names that include the words "hydrolyzed," "amino acids," and/or "protein." Most sun block creams and insect repellents also contain MSG.
Drinks, candy, and chewing gum are potential sources of hidden MSG and/or aspartame, neotame. and AminoSweet (the new name for aspartame). Aspartic acid, found in neotame, aspartame (NutraSweet), and AminoSweet, ordinarily causes MSG type reactions in MSG sensitive people. (It would appear that calling aspartame "AminoSweet" is industry's method of choice for hiding aspartame.) We have not seen Neotame used widely in the United States.
Aspartame will be found in some medications, including children's medications. For questions about the ingredients in pharmaceuticals, check with your pharmacist and/or read the product inserts for the names of “other” or “inert” ingredients.
Binders and fillers for medications, nutrients, and supplements, both prescription and non-prescription, enteral feeding materials, and some fluids administered intravenously in hospitals, may contain MSG.
According to the manufacturer, Varivax–Merck chicken pox vaccine (Varicella Virus Live), contains L-monosodium glutamate and hydrolyzed gelatin, both of which contain processed free glutamic acid (MSG) which causes brain lesions in young laboratory animals, and causes endocrine disturbances like OBESITY and REPRODUCTIVE disorders later in life. It would appear that most, if not all, live virus vaccines contain some ingredient(s) that contains MSG.
Reactions to MSG are dose related, i.e., some people react to even very small amounts. MSG-induced reactions may occur immediately after ingestion or after as much as 48 hours. The time lapse between ingestion and reaction is typically the same each time for a particular individual who ingests an amount of MSG that exceeds his or her individual tolerance level.
Remember: By food industry definition, all MSG is "naturally occurring." "Natural" doesn't mean "safe." "Natural" only means that the ingredient started out in nature, like arsenic and hydrochloric acid.
