Calcium
Good sources of the mineral calcium include milk, cheese and other dairy foods, green leafy vegetables (such as broccoli, cabbage and okra, but not spinach), soya beans, tofu, soya drinks with added calcium, nuts, bread and anything made with fortified flour, and fish where you eat the bones, such as sardines and pilchards.
Calcium has a number of important functions. For example it:
1) helps build strong bones and teeth
2) regulates muscle contraction, including the heartbeat
3) makes sure blood clots normally
It's thought that calcium may help to lower high blood pressure and may help to protect against colon and breast Cancer, although more evidence is needed to confirm this.
