[Nutritional factors associated with migraine].

Migraine is a chronic, highly prevalent, multidimensional, and complex disorder, influenced by genetic and environmental factors, among which is the diet. Medical treatments are partially effective, and that makes necessary to complement them with other therapeutic strategies. The nutrition plays a prevalent role. We will review dietary factors that have been linked to migraine and therapeutic nutritional guidelines about it: elimination, integral, ketogenic, epigenetic and hypocaloric diets, as well as diets that interest fatty acids, sodium, vitamins, and the gut-brain axis. To date, the evidence of the efficacy of nutritional treatments for migraine is not widespread and it is necessary to advise our patients about patterns consistent with nutritional general recommendations.
