Calcium is the dominant element in human bone. The body of a healthy adult contains about three pounds of calcium (1.4 kilogrammes).

Every day you lose calcium in your urine and faeces. If you do not replace what you lose, your bones will suffer in time.

Calcium is also essential for good tone and action of the skeletal muscles (those covering the body’s bony framework). It is also required for the proper functioning of nervous tissue and for normal blood clotting.

Calcium is known to relieve muscle cramps and also to promote sound sleep, which many sufferers of backache find elusive.

The best food sources of calcium include: blackstrap molasses, carob powder, citrus fruits, dried beans, dried figs, fish, green leafy vegetables (such as bok choy and spring greens, or collards), milk and milk products, peanuts, sardines, sesame seeds, soya beans and by-products such as tofu (soya bean curd), sunflower seeds, walnuts and watercress.
