There's evidence that certain foods can fuel the fire when it comes to migraines (via Nutrients). The commonly cited culprits include citrus fruits, chocolate, caffeine, alcohol, wheat, onions, and processed foods. Some foods may cause or heighten migraines upon withdrawal. It's suggested that certain ingredients also play a role in developing a migraine headache, like monosodium glutamate (MSG), histamine, tyramine, aspartame, and sucralose. Experts agree that people are sensitive to different things, so it's helpful to keep a diary and identify your specific dietary triggers.
People with chronic migraines can massively benefit from following a plant-based diet that's rich in dark leafy greens, according to a study published in BMJ Case Reports. It's believed that nutrient-dense foods, such as leafy vegetables, exert their therapeutic effects by reducing inflammation. These foods might even be more effective at lessening the frequency of migraine headaches than preventive and abortive migraine medications.
If you're prone to migraines, steer clear of migraine-triggering foods and drinks the day before you travel as well as during your journey. There are plenty of migraine-friendly foods you can take along with you to snack on, per MigraineAgain, including carrots, dark chocolate, and fresh fruits like bananas and figs.
