Food allergy or sensitivity plays a primary role in many cases of tension and migraine headaches. Many double-blind, placebo-controlled studies have demonstrated that the detection and removal of allergenic foods will eliminate or greatly reduce headache symptoms in the majority of patients. Food allergy/intolerance induces a migraine attack largely as a result of platelets releasing serotonin and histamine. In addition, foods such as aged cheeses, beer, canned figs, chicken liver, chocolate, food additives, pickled fish, the pods of broad beans, wine, and brewer&aposs yeast contain histamine, tyramine, and/or other compounds that can trigger migraines in sensitive individuals by causing blood vessels to expand. Red wine is much more likely than white wine to cause a headache because it contains higher levels of phenols and 20 to 200 times as much histamine.
Hypoglycemia can also trigger a migraine. Eating to prevent hypoglycemia also stabilizes blood vessels, preventing migraine attacks. Be sure to eat regularly, with small snacks between meals. Avoid sugar and refined carbohydrates, instead focusing on whole grains, legumes, fruits, and vegetables.
