“Protecting bone health is important throughout your life. Understand how diet, exercise and other lifestyle choices can affect bones.

Bones do a lot for your body. They provide structure, protect organs, anchor muscles and store calcium. While it’s important to build strong, healthy bones during your childhood and teen years, you can take steps to protect bone health when you’re an adult too.

Bones change all the time. The body constantly makes new bone and breaks down old bone. This process is called remodeling. When you’re young, new bone is made faster than old bone is broken down. So the amount of bone mass you have goes up. Most people reach peak bone mass around age 30. After that, bone remodeling continues. But you lose slightly more bone mass than you gain.
