We view migraine as a fascinating example of food reactive problems that allow us to examine the link between food, the circulating immune system and brain disturbances. Migraine sufferers are likely to respond well to adequate diet revision. It is usually not adequate just to eliminate a few things from the diet. While pain is the main event, many other symptoms that occur before, during, and after a headache can be explained as a delayed pattern food allergy mechanism. Typically, a migraine sufferer will follow a rhythmic or cyclic pattern.
Headaches come in attacks with variable symptom-free periods between attacks.
The underlying biorhythms and changes in tolerance for trigger substances will vary the response to the ingestion of trigger foods. While all the details of migraine's mechanisms are not yet understood, it is likely that many headaches are triggered by food antigens interacting with blood cells and blood-vessel walls. The pain of migraine arises from blood vessels, supplying blood to the brain. The first stage of blood vessel reaction is constriction. Migraine brain disturbances can be stroke-like, originating from reduced blood flow to the brain during the first stage of the headache.
