Calcium Is Critical

Calcium is an important mineral that helps keep bones and teeth strong and helps maintain proper function of the heart, muscles and nerves, according to the Centers for Disease Control and Prevention. Good sources of calcium include low-fat or nonfat milk, low-fat cheese and low-fat yogurt; dark green leafy vegetables; nuts; and calcium-fortified foods, such as orange juice, cereal, bread, soy beverages and tofu.
