Bones play many roles in the body — providing structure, protecting organs, anchoring muscles and storing calcium. While it's important to build strong and healthy bones during childhood and adolescence, you can take steps during adulthood to protect bone health, too.

What can I do to keep my bones healthy?

ou can take a few simple steps to prevent or slow bone loss. For example:

• Include plenty of calcium in your diet. For adults ages 19 to 50 and men ages 51 to 70, the Recommended Dietary Allowance (RDA) is 1,000 milligrams (mg) of calcium a day. The recommendation increases to 1,200 mg a day for women age 51 and older and for men age 71 and older.

• Good sources of calcium include dairy products, almonds, broccoli, kale, canned salmon with bones, sardines and soy products, such as tofu. If you find it difficult to get enough calcium from your diet, ask your doctor about supplements.

• Pay attention to vitamin D. Your body needs vitamin D to absorb calcium. For adults ages 19 to 70, the RDA of vitamin D is 600 international units (IUs) a day. The recommendation increases to 800 IUs a day for adults age 71 and older.

• Good sources of vitamin D include oily fish, such as salmon, trout, whitefish and tuna. Additionally, mushrooms, eggs and fortified foods, such as milk and cereals, are good sources of vitamin D. Sunlight also contributes to the body's production of vitamin D. If you're worried about getting enough vitamin D, ask your doctor about supplements.

• Include physical activity in your daily routine. Weight-bearing exercises, such as walking, jogging, and climbing stairs, can help you build strong bones and slow bone loss.

• Avoid substance abuse. Don't smoke. If you are a woman, avoid drinking more than one alcoholic drink each day. If you are a man, avoid drinking more than two alcoholic drinks a day.
