An excessive consumption of MSG can cause a "Chinese Restaurant Syndrome" and gastritis, gastric and duodenal ulcers. Therefore, the maximum dose of MSG should be reconsidered taking into account its influence on the secretory capacity of the stomach.
Chinese meals tend to be rather low in protein. They are also low in fiber, which seems to decrease hunger. Fiber is the indigestible component of grains, vegetables and fruits and fills the stomach before it is eliminated, and a full stomach decreases the release of ghrelin.
Merriam-Webster added “Chinese restaurant syndrome” to its dictionaries in 1993. The definition described symptoms affecting “susceptible persons eating food and especially Chinese food heavily seasoned with monosodium glutamate.”
