And Monosodium Glutamate

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, an amino acid. It is found naturally in many foods like tomatoes and cheese. It can be produced commercially through fermentation of plant-based ingredients like sugar beets or corn.

MSG is used as a flavor enhancer to add an umami taste, which is a savory flavor. It is often found in processed foods such as soups, broths, sauces, and snack foods, as well as in some spice blends.

In the US, MSG is generally recognized as safe (GRAS) by the FDA. Some individuals report experiencing short-term symptoms like headache or flushing after consuming MSG, but scientific studies have not consistently linked these symptoms to MSG consumption in the general population. JECFA has evaluated MSG and established an acceptable daily intake. EFSA has also evaluated MSG. While some public concern exists, major health organizations state that for most people, MSG is safe to consume at typical levels.
