Determine food allergies by fasting for a week, then adding one food at a time to your diet.
Reactions can occur from twenty minutes to two weeks after ingesting the irritating food.
Avoid aged protein foods, such as hot dogs, cheese, sausages, cold cuts and smoked or pickled fish, as they contain tyramine, a vasoactive amine, which has been shown to trigger migraine attacks. Tyramine is also found in alcoholic beverages. Red wine should be avoided not only because of its tyramine content but also because it contains flavonoids which inhibit the activity of the enzyme which normally breaks down tyramine and other vasoactive amines in the body. Reduce the intake of animal fats. The arachidonic acid they contain tends to increase blood clotting, which is associated with migraines.
