There are many types of headaches and not all severe headaches are migraines.  The Mayo Clinic  defines a migraine as ” severe throbbing pain or a pulsing sensation, usually on just one side of the head. It’s often accompanied by nausea, vomiting, and extreme sensitivity to light and sound.”
The best way to identify foods that may be triggering your migraine is to keep a daily
food journal. A journal allows you to look back and identify specific foods that may be
contributing. If you can identify food triggers, then you’ll be able to avoid them and reduce how often you get migraines.

Not all triggers affect everybody, but here’s a list of commonly reported
triggers:

pie).
