In some people, certain foods and drinks -- or components they contain -- can trigger a migraine. One well-accepted migraine trigger is tyramine.
Tyramine is a substance found naturally in some foods. It's especially found in aged and fermented foods, such as:
Some types of beer
Also, foods high in protein may contain more tyramine if:
They have been stored for a long time
They have not been kept cold enough
About 20% of people with migraines have headaches preceded by aura, which can include:
Blind spots or zigzags in your field of vision
Aura may also include numbness or tingling on one side of the body. Aura without head pain is also a form of migraine.
Migraines are often prompted by one or more triggers, including:
Too much or too little sleep
Here's a look at the way the foods you eat may have an impact on migraine headaches.
Why It's Tough to Target Food Triggers
Certain foods are often blamed for provoking migraines. But scientific evidence linking food to migraine is sparse, and in some cases, nonexistent.
"It may be the case that food triggers migraine," says Elizabeth Loder, MD. Loder is co-author of The Migraine Solution.
"For the most part, people have different food triggers. So it's hard to define a list that applies to all headaches," Loder tells WebMD.
Other reasons make it tough to target food triggers.
Foods may become triggers only when combined with other, stronger headache-starters, such as stress and hormonal changes.
"If you're feeling stressed, you skip breakfast and then you eat a hot dog for lunch. I'm not so sure you can blame the hot dog for your migraine," says Dawn Marcus, MD. Marcus is the author of The Woman's Migraine Toolkit and a professor at the University of Pittsburgh.
A suspect food may not trigger a migraine every time. In addition, an attack may depend on the amount of the food you eat. To further muddy the waters, you may not get a headache for several hours to several days after eating a trigger food.
Identifying Your Personal Food Triggers
Identifying your personal food triggers can be complicated. Experts say it's worth keeping a food diary to determine whether a food bothers you. But they also say there's no need to avoid common migraine-causing foods if they don't bring on your headaches.
