Calcium
Calcium is a mineral the body needs to make bones and teeth, transmit nerve messages, tighten (contract) muscles, and help the blood to clot and the heart to function properly. Calcium is found in milk and milk products (including yogurt and cheese), in certain leafy, green vegetables (broccoli, spinach, kale), in legumes, and in some nuts.
Most people do not get enough calcium through diet alone. A person needs to eat 3 to 4 servings per day of foods high in calcium to get the recommended daily amount.
