So, as well as eating the right foods another way to keep your bones nice and healthy is...
EXERCISE - any kind of weight bearing exercise will do from strength training to regular power walks or a gym session. Aim for a minimum of 30 minutes, 3 times a week.
Weight-bearing physical activity allows new bone tissue to form, which makes bones stronger. It also makes muscles stronger. Bones and muscles both become stronger when muscles push and tug against bones during physical activity.
So keep moving and keep your bones healthy!
