Episodic migraine is a debilitating chronic pain condition afflicting 12% of American adults. Current conventional treatments rely on medications that provide limited or transient relief, target symptoms rather than the underlying causes of pain, and are associated with significant side effects and costs. It is therefore essential to investigate non-pharmacologic approaches to conventional headache treatments. Certain fatty acids and their bioactive metabolites regulate multiple pain-related biochemical pathways. Controlled clinical trials investigating pain modulation in response to dietary changes while exploring relevant mechanisms of action in humans are lacking.
