Russell L. Blaylock, MD, has written Excitoxins: The Taste that Kills, in which he explains that certain amino acids when overly abundant in the brain can cause neurons to die. Many biochemicals can act as neurotransmitters in the brain—some excite our neurons; others calm them. In particular, glutamate, aspartate, and cysteine are three amino acids that excite our neurons and can be called "excitotoxins." They are now added in large amounts to our food supply.
