It’s a vicious cycle: Heavy periods can flush out the body’s stores of iron, resulting in anemia -- and this condition can make uterine blood vessels more fragile, triggering even heavier periods, say researchers at Harvard Medical School. The good news? Up to 55 percent of women can break this cycle and lighten their periods within three months, just by restocking their body’s depleted iron stores, say UCLA researchers. So, enjoy 4 ounces of iron-rich beef, pork or chicken daily -- or if you prefer vegetarian fare, pair your cereals, breads and other grains with acidic foods, like citrus or berries. The iron found in grains is tougher to absorb, but Tufts researchers say ramping up the acidity in your tummy will double your ability to soak up this type of iron.
