Effect of Monosodium Glutamate Supplementation on Gastric Emptying and Postprandial Nitrogen Kinetics

Effect of Monosodium Glutamate on Gastric Emptying and Postprandial Nitrogen in Healthy Volunteers

There are receptors to free glutamate in the oral cavity and stomach that may mediate effects of this amino acid on gastrointestinal physiology. The investigators hypothesize that a chronic supplementation of monosodium glutamate (MSG) could modulate gastric emptying and the further metabolism of dietary protein in healthy subjects.
