Monosodium glutamate is propagandized by The Glutamate Association.
Glutamic acid is a neurotransmitter.
Monosodium glutamate, a salt, breaks down into an acid during digestion and travels in your blood as a neurological substance, or drug, a neurotropic drug. Reactions to neurotropic drugs are diverse. This is an excitotoxin. An excitotoxin is a group of compounds that can cause special neurons within the nervous system to become overexcited to the point that these cells will die. An imbalance of these excitotoxins during critical periods of brain development can result in an abnormal miswiring of the brain.
