Minerals: Online Minerals Information Centre

Minerals are inorganic substances like sodium, potassium, chlorine, phosphorus, magnesium, calcium, iodine, iron, cobalt, copper. Minerals are the most basic form into which organic matter can be broken. Minerals play an important role in the health of your body in terms of healthy bones, teeth, hair, nails, nerve and muscle activity and regulation of body fluids.

Benefits of Minerals

Minerals are essential for regulating and building the cells which make up the body. Minerals help to maintain the volume of water necessary for the life processes in the body. These are essential for the proper growth and assimilation of the organic substances, and development of every part of the body. Each of the essential food minerals does a specific job in the body, while some of them do extra work in teams to keep the body cells healthy. Even slight changes in the concentration of the important minerals in the blood may rapidly endanger life.

Sources of Minerals

Plants incorporate minerals from the soil into their own tisses. For this reason fruits, vegetables, grains, legumes, nuts and seeds are often excellent sources of minerals. Minerals, as they occur in the earth in their natural form, are inorgainc or lifeless. In plants, however, most minerals are combined with organic molecules. This usually results in better mineral absorption. Green leafy vegetables are the best source of many minerals.

Minerals are classified into two categories: major and minor, on the basis of intake level.

In the above graph, minerals from calcium to magnesium are major minerals, and minerals after that are trace minerals.
