Beginning on page 66 is a detailed description of dietary triggers and why they happen. This will take you a bit to get thru, but is well worth the read! This is the best online source I’ve ever found that gives a fairly detailed look at the importance of diet in Migraine, and it is by far the link I most generally refer beginners to as well as using it myself. This lengthy online book does an excellent job of describing alternative ways of curbing migraine.
