Pre-menstrual syndrome (PMS) is that time of the month just before a woman’s cycle starts where her hormones may feel completely out of balance resulting in mood swings (!), tender breasts, weight gain, acne, and fatigue. The hormones responsible are primarily a balance between progesterone and estrogen however other hormones such as cortisol (from the adrenals) and serotonin (the brain hormone) can play a role. Other than massive amounts of chocolate (right?), here are 3 of the best foods to eat all month long to help smooth out the ups and downs of PMS. No, it does not include wine.
