The best way to build stronger bones is to eat foods high in calcium. These include low-fat milk and dairy products, such as yogurt and cheese, as well as milk-based puddings and soups.
Deep green leafy vegetables, such as spinach, kale, and turnip greens, are also high in calcium. Calcium-fortified soy milk products, sardines or canned salmon with bones, calcium-fortified cereals, and almonds can also add calcium to the diet.
Your body needs vitamin D to help absorb calcium. Look for dairy and other food products that are fortified with vitamin D, or spend some time in the sunshine with your spouse.
