Aged cheeses like cheddar contain the amino acid tyramine, which triggers the release of hormones that constrict your blood vessels. The blood vessels then dilate, leading to that familiar throbbing in your head. Also, cured meats like bacon are loaded with nitrates, which have a similar effect.
A SCOOP OF ROCKY ROAD
America's favorite dessert packs a double whammy: Not only is chocolate rich in tyramine; but if you're cold-sensitive, each frosty mouthful sends shock waves through your nerves and blood vessels, causing a throbbing pain in your forehead and temples.

A FINE BURGUNDY
When it comes to cocktails, keep it light: Dark-colored libations like red wine, scotch and dark beers are rich in headache-causing tyramine. White wine, vodka and lighter beers are safer choices -- in moderation, of course.
