Glutamic Acid and the Alpha-Gal Friendly Diet

Glutamic acid is an amino acid that is part of many proteins found in both plant and animal sources. It is commonly used as a food additive for flavor enhancement and is known for its role in the umami taste. As a non-essential amino acid, it can be synthesized by the human body, but it is also consumed through dietary sources. In the food industry, it can be listed under various names, including E620 or L-glutamic acid.
