MSG is not REALLY so terrible an additive if you think about it...just the sodium salt of glutamic acid, which is an amino acid ABSOLUTELY essential to life and sodium is well, SODIUM.
Believe me, if MSG was so dangerous a food additive as some people claim, the streets of Chinatown would be littered with corpses piled 10 deep. Sometimes I think it's just a whipping boy..picture someone turning his nose up at some MSG on steamed Chinese veg and getting a Big Mac instead.
Global demand of this stuff is nearly 2 million TONS with more than half consumed in China. I use it by the pinchful and have never had a problem.
But if someone is allergic, he's allergic!
