People complain about a lot of things. That doesn't mean it's true. Maybe it is for some individuals, maybe it's in their head due to stereotyping/priming. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4870486/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4870486/ > From the fact that the results of the human studies are not consistent and it is assumed that most studies using beverages as a vehicle are not properly blinded, we suggest that a causal relationship between MSG and headache has not been proven. In addition, statistically significant differences in the incidence of headache were not observed when MSG was administered with food, except in one case of the female group where the blind integrity was questionable. It would seem premature to conclude that the MSG present in food causes headache.
