Relatively higher amounts of MSG are used in foods prepared at Chinese restaurants, which is why the phrase “Chinese Restaurant Syndrome” is often used to describe the symptoms some consumers experience after consuming MSG at such a restaurant, reports About.com.

People with MSG sensitivity may experience symptoms such as drowsiness, palpitations, flushing, headaches and numbness after consuming a large amount of MSG.
