Foods That Trigger Headaches

For many headache and migraine sufferers, certain foods can act as triggers.

One viewer sent this question to Dr. Manny Alvarez, senior managing health editor of FoxNews.com:

Dear Dr. Manny,
I've noticed that whenever I eat red grapes I get a headache. Could there be something in them that is causing this to happen?
Thanks, Jay

Alvarez said grapes are low in calories and rich in vitamin C and fiber, so they are a nutritional snack. But they also contain a substance called tyramine, a naturally occurring amino acid that forms from the breakdown of protein in food as it ages.
