I work in a chinese restaurant (Mr. Chow) and most of the food there contains MSG. .
A lot of other food that you buy elsewhere contains MSG as well. It may not be listed as MSG, though. For example if the ingredients on a product say 'meat tenderiser' that is MSG. The link posted by julio explains this in more detail. So if you really want to avoid it completely, you will have to learn a lot more about it and not just avoid chinese restaurant food
Really? I first heard of it when the shit hit the fan somewhere in the 80's. I only found out that 'meat tenderiser' could be MSG a few years ago. Until then meat tenderiser to me was a guy with a mallet bashing the meat!
