What’s the fuss about calcium?

We all know calcium is essential for strong bones and teeth, but it plays a role in muscle and nerve function, blood clotting, and regulating blood pressure. If you do not consume enough calcium each day, the body will take what it needs from your bones.

Younger people need calcium to during peak growth periods to ensure that ‘peak bone density’ is achieved. When bones become thin, osteoporosis may develop. Osteoporosis affects both men and women, but post-menopausal women are particularly at risk because they lose calcium more easily from their bones.

To keep our bones strong, and prevent osteoporosis, a diet rich in calcium and lots of weight bearing exercise is recommended.
