What is calcium?
Calcium is an essential mineral that is required for the body to function properly.
We all know that calcium is needed to build strong bones and teeth. In addition, it is required for every cell of the body to function at its optimum. It is used by nerves and muscles and helps our blood clot.
How much calcium should we consume daily?
Teens require a lot of calcium, as adolescence is a time when bones grow rapidly. The stronger the bone development during this time, the healthier the bones will be during adulthood. Calcium needs stabilise once a person reaches full growth, but there are times when they increase, such as pregnancy, breastfeeding and healing from injuries.
The elderly have to pay special attention to the level of calcium in their diet in order to prevent osteoporosis, a condition where the bones become brittle and fragile due to hormonal changes or deficiency of calcium and vitamin D.
