TБhe foods we eat have important minerals and vitamins that help build strong and healthy bones. and are two important nutrients for bone health. Almost all the calcium in the body is found in the bones and teeth. Calcium is also found in the blood, where it helps the heart, muscles and nerves to work properly. The bones are like a bank – they build up deposits of calcium from the foods that we eat and drink or from calciumбsupplements. They also \’give\’ calcium to the rest of the body by allowing it to enter the bloodstream. If you do not eat enough calcium, your body cannot replace the calcium that the bones lose quickly enough. Soon, the bone bank becomes empty and bones get weaker. How much calcium does a person need? The amount of calcium that a person needs is based on their age, as you can see in the table below. You can use the calcium-rich foods listed in the tables below to reach the recommended daily intake of calcium for you and your family.
