When exploring the causes of headaches, the easiest, cheapest place to start is diet. Food reactions are a significant contributor to headaches and some improvement in symptoms, if not complete remission, can always be achieved by eliminating problematic dietary items. The elimination/challenge trial identify food reactions that may be causing your headaches.
Foods that most commonly induce migraines:
Foods like cheese, beer, and wine induce migraines in some people because they contain histamines and/or vasoactive compounds that cause blood vessels to expand. Women tend to react to histamine-containing foods more frequently than men do, on account of a deficiency in an enzyme (diamine oxidase) that breaks histamine down. Taking supplemental B6 may be helpful in these situations, as it can increase diamine oxidase activity.
