What is Monosodium Glutamate (MSG)?

Monosodium Glutamate (MSG) is a flavor enhancer commonly used in food products to provide umami, a savory taste. It is produced by fermenting starches or sugars and then neutralizing the resulting glutamic acid with sodium.

MSG is widely used in processed foods, snacks, and restaurant cuisines to enhance the flavor profile. The health evidence regarding MSG is mixed; some studies suggest that large doses may cause transient symptoms like headaches or flushing in sensitive individuals, while others find no adverse effects with typical dietary exposure levels.

For those concerned about MSG, it is worth noting its labeling as E621 in packaged foods, which helps consumers identify its presence.

Commonly found in: soups, snack foods, processed meats, condiments, frozen entrees
