There are plenty of studies to show that osteoporosis (brittle bones) prevention begins in childhood. Children and teenagers can actually make "deposits" in their "bone banks." Impact activities such as gymnastics, basketball, soccer, and volleyball put loading forces on the bones.

These forces actually stimulate bone growth. As we age, there is a decline in bone density. This is much worse in women after menopause.

The National Osteoporosis Foundation (NOF) recommends daily calcium and vitamin D along with regular physical activity and exercise to prevent loss and maintain bone density. Weight-bearing exercise and activities is best. Avoid smoking and excess alcohol.

To help you understand your own personal risk of osteoporosis read the NOF brochure: Take Action: Healthy Bones, Build Them for Life! [Available online: https://www.nof.org/osteoporosis/web_SG_broch.pdf]. You'll see in that brochure that a calcium-rich diet is very important in children and adolescents. This can be supplemented with calcium pills starting in young adulthood. Activity and exercise are important throughout the lifespan.
