The FDA and current research has not be able to find evidence linking MSG to any long-term conditions or diseases. However, if you have noticed some of these symptoms after eating you may want to limit MSG intake and see if the symptoms improve. It is important to remember that other additives also contain MSG so it can be found under other names like hydrolyzed vegetable proteins, autolyzed vegetable proteins, autolyzed yeast, hydrolyzed yeast, yeast extract, soy extracts, and protein isolate.
