What effects does MSG have on diet, obesity, health and food cravings?
Because MSG is absorbed very quickly in the gastrointestinal tract (unlike glutamic acid-containing proteins in foods), MSG could spike blood plasma levels of glutamate. Glutamic acid is in a class of chemicals known as excitotoxins, high levels of which have been shown in animal studies to cause damage to areas of the brain unprotected by the blood-brain barrier and that a variety of chronic diseases can arise out of this neurotoxicity.
