How inflammation drives migraines
Migraine is increasingly understood as a neurogenic inflammatory disorder rather than a simple vascular event. During an attack, activation of the trigeminovascular system releases inflammatory neuropeptides — most notably calcitonin gene-related peptide (CGRP) — which dilate cranial blood vessels and sensitize pain-signaling neurons. Mast cells in the meninges degranulate, releasing histamine and pro-inflammatory cytokines that amplify pain.
Underlying this acute response is a more chronic state of low-grade inflammation and oxidative stress. People prone to migraine often show evidence of mitochondrial dysfunction, elevated CRP, and altered gut-brain axis signaling. This is why dietary patterns that broadly reduce systemic inflammation — Mediterranean-style eating, omega-3 sufficiency, polyphenol-rich plants — show meaningful benefit even though they don’t target a single pathway.
Why these foods help
The most compelling foods for migraine prevention act on multiple steps in the inflammatory cascade. Ginger inhibits prostaglandin synthesis and shows efficacy comparable to sumatriptan in small trials. Curcumin in turmeric blocks NF-κB activation upstream of cytokine release. Magnesium-rich greens and seeds correct the magnesium deficiency seen in many migraine sufferers. Riboflavin (vitamin B2, in dairy and eggs) supports mitochondrial function; CoQ10-rich foods do the same. Omega-3s from fatty fish shift eicosanoid balance away from inflammatory prostaglandins.
Hydration, regular meal timing, and consistent caffeine intake also matter — but those are habits more than foods.
