those of you on the conspiracy theory bandwagon with MSG should do your research. it is the salt form of l-glutamine, the most abundant amino acid in the body, and is found in chemically identical form in tomatoes, mushrooms, beef, seaweed, etc. asians have eaten it for over 100 years with no ill effects. sodium is not good in excess, but this should go without saying. if you use 1/4 t. per 4 servings it is healthy and safe. maybe your migraines come from being neurotic about things.
