Migraine is a food-allergic disease
Abstract
Foods which provoked migraine in 9 patients with severe migraine refractory to drug therapy were identified. The patients were then given either sodium cromoglycate or placebo orally in a double-blind manner, with foods previously identified as provocants. Sodium cromoglycate exerted a protective effect, thus confirming that it can prevent a hypersensitivity mechanism as well as the symptoms of migraine. Immune complexes were not produced in those patients who were protected by sodium cromoglycate. These observations confirm that a food-allergic reaction is the cause of migraine in this group of patients.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 9 participants or records.
