Monosodium glutamate (MSG) is a flavor enhancer commonly used in cooking. It is the sodium salt of glutamic acid, an amino acid found naturally in many foods, such as tomatoes and cheese. MSG is often added to savory dishes to enhance their umami taste, which is one of the five basic tastes alongside sweet, sour, bitter, and salty. MSG has been the subject of various studies regarding its safety. Regulatory agencies like the U.S. Food and Drug Administration (FDA) consider it safe for consumption. However, some individuals may experience mild reactions, often referred to as "Chinese restaurant syndrome," after consuming large amounts of MSG.
