AAN 2019 Annual Meeting Coverage

The relationship between food and migraine is complex, and while the literature on certain foods triggering migraine is limited and conflicting,1,2 During AAN 2019 Annual Meeting, Dr Belinda Savage-Edwards spoke about the benefits of identifying an individual’s migraine triggers and adapting the daily diet to prevent migraines.

Dr Savage-Edwards started by alerting the audience of the uncertainties surrounding food and migraine—10% or less of migraineurs are sensitive to food triggers, and very few triggers are known to consistently cause migraines. Moreover, the identification of food triggers requires strict monitoring of dietary intake and time to migraine onset after consumption. Additionally, Dr Savage-Edwards highlighted that food as a migraine trigger is secondary to primary triggers, which include stress, lack of sleep, irregular sleeping patterns, and changes in temperature, among others.3 Nevertheless, Dr Savage-Edwards pointed out that although evidence is lacking, the removal of certain dietary components, and the introduction of others, has led to improvement in her patients suffering from migraines.

Dr Savage-Edwards presented a list of headache triggers—including food items such as dairy products, alcohol, caffeine, and processed meats—and a list of headache fighters—whole grains, vegetables, non-citrus fruits, and water. She further proposed that with the aid of a food diary, individuals can identify migraine triggers by adopting a diet free of known triggers, and reintroducing food items one at a time taking note of any headache occurring within 24 hours. Dr Savage-Edwards finished her presentation by recommending a ‘migraine diet’ which includes foods high in omega 3 fatty acids, riboflavin and magnesium, and foods low in fat, tyramine, histamine and phenylethylamine.

While some studies have showed improvement in severity of migraines following a low-fat plant-based4,5 diets, further research is needed to establish prevention of migraines through controlled diet.
