MSG, or monosodium glutamate, is a common and widespread additive in food used mainly for flavor enhancement, but also for preservation. MSG has been used for well over a century as a food additive, but in the last couple of decades anecdotal claims of illness have been linked to MSG consumption.SG is the salt form of glutamic acid, which is a naturally occurring amino acid. Seaweeds and many other plants and vegetables contain glutamic acid.
