Sugar Monosodium Glutamate

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, an amino acid found naturally in many foods. It is produced commercially through the fermentation of starch, sugar beets, or sugarcane. MSG enhances the savory "umami" taste of foods.

Manufacturers add MSG to foods to enhance their savory flavor, particularly in processed items. It is commonly found in seasoning mixes, broths, canned soups, processed meats, and snack foods.

MSG is generally recognized as safe (GRAS) by the FDA for use in food. Some individuals report sensitivity to MSG, experiencing symptoms like headaches or flushing, though scientific studies have not consistently linked these symptoms to MSG consumption at typical levels. JECFA and EFSA have evaluated MSG and established acceptable daily intakes. The FDA has stated that while some people report sensitivity, double-blind, placebo-controlled studies have failed to consistently prove a link.
