MSG 

A preservative sometimes used in frozen food, particularly western-style Chinese cuisine.

I only eat Chinese food fresh at restaurants, because the MSG in the frozen meals makes my head throb all night.

A natural, that's right, NATURAL ingredient in some foods. The glutamate ion is a form of a widespread, naturally occurring amino acid. Some naturally occurring instances include tomatoes, parmesan cheese, peas, corn and most meat. Too much MSG will cause people to become hungry more often, and that is the Chinese restaurant's fault.

MSG will raise your blood pressure and (very rarely) cause epileptic seizures. But it still tastes good.
