Calcium - Nutritional factors and bone health

Calcium accounts for 1 - 2% of the adult human's body weight.

The adult human body contains about 1200g of calcium.

Of this amount, over 99% is found in mineralised tissues, such as bones and teeth.

The amount of calcium needed changes throughout the different stage of life.

In the pre-pubescence years calcium requirements are high due to rapid growth of the skeleton.

Milk and other dairy products are the most important sources of calcium.

Other good food sources of calcium include some;

* Green vegetables, like brocoli;

* Canned fish with soft edible bones, such as sardines, pilchards and salmon;

* Nuts - especially Brazil nut and almonds; and some fruits, such as oranges and apricots.
