The PMS Diet

Step away from the potato chips and French-onion dip— salty, fatty indulgences will make you feel even more bloated. The perfect replacement involves two superfoods that are especially effective at this time of the month.

Best bet: Sunchoke chips (they're easy to make) and guacamole. Sunchokes are high in thiamine—they have 400 times the amount found in potatoes—and a recent study in the American Journal of Clinical Nutrition found that healthy doses of thiamine (or vitamin B1) can make you less likely to develop PMS.
