You may think a migraine is solely a head issue, but a new University of Cincinnati study found that what you put in your stomach plays a role. If you're at risk, follow these rules from Vincent T. Martin, MD, professor of medicine, departments of internal medicine and neurology, at the University of Cincinnati:

1. Skip the aspartame.

This sweetener is a migraine trigger for some, so check the ingredient list on lowfat yogurts to make sure there's none hidden inside.

2. Find a new favorite cocktail.

Beer and red wine have been linked to headaches—researchers point to chemicals in the drinks as culprits.

3. Cut out gluten.

It may activate a migraine if you have celiac disease or gluten sensitivity. Talk to your doctor; a blood test can confirm those issues.

4. Keep drinking coffee.

Particularly if you sip it every morning. Forgoing your Joe one day means you'll likely have a full-fledged headache the next.
