The US FDA in 1995 issued a report on MSG that stated the following:
Among the report's key findings:
* An unknown percentage of the population may react to MSG and develop MSG symptom complex, a condition characterized by one or more of the following symptoms:
* burning sensation in the back of the neck, forearms and chest
* numbness in the back of the neck, radiating to the arms and back
* tingling, warmth and weakness in the face, temples, upper back, neck and arms
* facial pressure or tightness
* chest pain
* headache
* nausea
* rapid heartbeat
* bronchospasm (difficulty breathing) in MSG-intolerant people with asthma
* drowsiness
* weakness.
* In otherwise healthy MSG-intolerant people, the MSG symptom complex tends to occur within one hour after eating 3 grams or more of MSG on an empty stomach or without other food. A typical serving of glutamate-treated food contains less than 0.5 grams of MSG. A reaction is most likely if the MSG is eaten in a large quantity or in a liquid, such as a clear soup.
* Severe, poorly controlled asthma may be a predisposing medical condition for MSG symptom complex.
* No evidence exists to suggest that dietary MSG or glutamate contributes to Alzheimer's disease, Huntington's chorea, amyotrophic lateral sclerosis, AIDS dementia complex, or any other long-term or chronic diseases.
* No evidence exists to suggest that dietary MSG causes brain lesions or damages nerve cells in humans.
* The level of vitamin B6 in a person's body plays a role in glutamate metabolism, and the possible impact of marginal B6 intake should be considered in future research.
* There is no scientific evidence that the levels of glutamate in hydrolyzed proteins causes adverse effects or that other manufactured glutamate has effects different from glutamate normally found in foods.
