Prevent PMS with yogurt...

Up to 80 percent of women will struggle with premenstrual syndrome and its uncomfortable symptoms, report Yale researchers.  The reason: Their nervous systems are sensitive to the ups and downs in estrogen and progesterone that occur naturally every month.  But snacking on 2 cups of yogurt a day can slash these symptoms by 48 percent, say researchers at New York’s Columbia University.  “Yogurt is rich in calcium, a mineral that naturally calms the nervous system, preventing painful symptoms even when hormones are in flux,” explains Mary Jane Minkin, M.D., a professor of gynecology at Yale University.
