Is MSG Bad for You?

Quick Answer: Scientific consensus says MSG (monosodium glutamate) is safe for most people. The FDA classifies it as GRAS (Generally Recognized as Safe). Claims of "Chinese Restaurant Syndrome" have been debunked as having no scientific basis. However, some individuals may experience mild sensitivity.

MSG is a flavor enhancer that adds umami (savory) taste to food. It occurs naturally in tomatoes, parmesan cheese, soy sauce, and mushrooms. The negative perception of MSG originated from a 1968 letter to the New England Journal of Medicine describing "Chinese Restaurant Syndrome" — which multiple double-blind studies have failed to reproduce. The FDA, WHO, EFSA, and the American Chemical Society all consider MSG safe. However, the EU set an acceptable daily intake of 30mg/kg body weight in 2017 as a precautionary measure. Some people report sensitivity symptoms (headache, flushing) at very high doses, but controlled studies have not confirmed a consistent link. MSG contains about one-third the sodium of table salt, so it can actually help reduce overall sodium intake when used as a partial salt replacement.
