Calcium is a mineral that is necessary for life. In addition to building bones and keeping them healthy, calcium enables our blood to clot, our muscles to contract, and our heart to beat. About 99% of the calcium in our bodies is in our bones and teeth.
Sources of calcium include
milk, cheese and other dairy foods
green leafy vegetables – such as curly kale, okra and spinach
soya drinks with added calcium
bread and anything made with fortified flour
fish where you eat the bones – such as sardines and pilchards
