Scientists think that MSG may lead to many neurological disorders  . In mice studies done by a university, the evidence showed the mice didn't want to eat the food including MSG. Today many food companies "hide" MSG on food labels   by using different names. If you see "natural flavorings", "hydrolyzed protein" and "spices" in a food label, you are probably seeing a hidden way to "report" MSG in a food label.
