You Asked: Can Foods Trigger A Migraine?
Found in processed meats like sausage, bacon, and cold cuts, these preservatives actually aren't the culprit themselves. Bacteria in your mouth converts nitrates to nitrites, and headaches are a known side effect of ingesting nitrites.
Aged and fermented foods are often high in this substance, which may cause migraines. If you've noticed your head pounding after going to town on a cheese plate or finishing off a big glass of Cab Sav, best to go easy on cured meats, harder cheeses, and even things like pickles and olives. And stick to one glass of red or tap beer: Tyramine is present there, too.
