CHINESE RESTAURANT SYNDROME – attributed to the flavor enhancer monosodium glutamate (MSG) which is commonly added to Chinese food, the symptoms of Chinese Restaurant Syndrome can include feelings of numbness, pressure, warmth or tingling of the skin at the back of the neck and extending to the back and arms; nausea; chest pain, rapid heartrate, or heart palpitations; bronchial reaction in asthmatics; weakness and drowsiness. The onset is usually within 15 to 20 minutes of ingesting food and symptoms persist for around 2 hours. Though this syndrome has been reported by many, clinical studies to date have yet to demonstrate a significant relationship between the consumption of (pure) MSG and this syndrome. Though no current studies have tested the effects of MSG consumed in the context of Chinese food – perhaps MSG in combination with other ingredients often found in American Chinese food may bring about this reaction in some individuals. MSG is a known excitotoxin at higher blood serum levels, though beyond what one would experience from eating Chinese food.
