Monosodium Glutamate: Weight Gain?

Many people still avoid MSG as the culprit in "Chinese restaurant syndrome", even though no scientific studies were ever able to show that MSG causes headaches, flushing, tingling or anything else. However, a recent study of Chinese peasants suggests that MSG may cause weight gain (Obesity, August 2008). The subjects were divided into three groups, based on the amount of MSG used, and those in the group that ate the most MSG were nearly three times more likely to be overweight than non-users. Previous studies on mice and rats found the same effect. Dr. Ka He, the lead author of the study at the University of North Carolina, concludes that MSG makes food taste better so people eat more.

It's not easy to avoid MSG even if you read food labels. Everyone eats significant amounts of monosodium glutamate because all foods that contain protein have a building block amino acid called glutamic acid which is converted in the body to glutamate. More
