Wow...I am literally right now talking to my husband about this!! My trigger is beef. I have been reading a lot online about beef related migraines. I almost never get headaches and have been getting them once a week the last several months. I realized, it was the one time a week we eat beef. Cutting out beef has almost completely diminished them. Nitrates are also a huge trigger for me. They are in processed meats...bacon, hotdogs, deli meat, etc. I hardly eat any of those, but every time I do, I get headaches.
