Foods containing MSG

The sodium salt of glutamic acid, which is present in the body naturally, is called monosodium glutamate (MSG). MSG is a food additive that can be found in a variety of foods.

According to the American Migraine Foundation, 10 to 15% of migraine sufferers may experience severe migraine attacks after consuming foods containing MSG. Some people may also be triggered by other preservatives. Most research has shown that consuming high doses of MSG of 3 grams or more may have adverse effects, such as high blood pressure and headaches. While headaches and migraine attacks are among the most commonly reported side effects of consuming MSG, current research has not confirmed a connection between the two.
