The good news is that osteoporosis is largely preventable. The goal is to build up as much bone strength as possible by the time your body stops actively making bone. This occurs when you reach peak bone mass at approximately 20 years of age. Up until this time, bones are actively being built and strengthened during the natural process of remodeling. Specialized bone cells called osteoclasts break down and remove old bone tissue. Then, new bone is formed by osteoblasts.
Once peak bone mass is achieved, however, nothing more can be done to build bone mass. All you can do is maintain your bone mass as your body begins to break down bone mass faster than new bone can be built. But if someone consumes enough calcium and vitamin D and does weight-bearing exercises during childhood and adolescence, she can build her bone mass high enough to reach the maximum peak bone mass possible and prevent going bankrupt in the bone department later in life.

Milk does a body good, but only if it's actually put into the body. A glass of milk contains 300 milligrams of calcium, almost one-fourth of the recommended daily intake of 1,300 milligrams for a child between the ages of 9 and 18. However, getting kids to drink their milk isn't always easy.
"Calcium deficiency is very, very common in the United States, and throughout the world, in fact," Dr. Petak said. "Sufficient calcium intake is important at every age, from infancy through the oldest Americans."
