Monosodium glutamate (MSG) may be most commonly associated with Chinese food, but this odorless, crystalline additive is used throughout the restaurant industry, and is even added to many packaged foods you may be eating. But what exactly is MSG? And why might you consider avoiding foods that contain it?
What is MSG?
MSG is a flavor enhancer that’s frequently added to canned vegetables, soups, deli meats, and restaurant foods to lend a savory, rich flavor. It’s made from sodium and L-glutamic acid, a nonessential amino acid that occurs naturally in umami-rich foods like tomatoes, anchovies, mushrooms, and Parmesan cheese.
