Some who suffer from migraines list chocolate as a possible trigger food. Some neurologists say it is a migraine trigger because it contains the amino acid tyramine (...). But the connection could be that women tend to crave chocolate during stress and hormonal changes, both of which also may trigger headaches. The amount of chocolate can be an issue, too. Experiment to see if you can eat a small, but satisfying amount of chocolate without triggering a headache.
