Vasodilation of the blood vessels may be caused by consumption of, or exposure to, nitrates and nitrites, which may trigger a vascular headache. Nitrates are found in some medications for heart problems and in some chemicals used in the food and beverage industry.

Food preservatives, such nitrates and nitrites, found in processed meats might trigger migraines. Such additives can be found in hot dogs, ham, sausage, bacon and lunch meats, experts say.
