Foods that are calcium powerhouses can boost your bone health in four ways. First, the calcium in them helps prevent the thinning that is virtually inevitable for your postmenopausal skeleton. Second, several of the foods up your intake of vitamin D, which is also important for bone health. Third, when you eat calcium-rich foods, you enhance the effect of any osteoporosis drugs you may be taking. And finally, foods with calcium content heighten the benefit of weight-bearing exercise. Supplements can't entirely make up for a lack of calcium and vitamin D in your diet, so promise yourself to add these 15 good-and-good-for-you choices to your meal plan starting today!
