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.
