Dietary minerals are the chemical elements needed by your body in addition to the four continuously present elements: carbon, hydrogen, nitrogen and oxygen. They can be divided into bulk minerals (of which your body needs at least 100mg per day), and trace minerals (of which you need only tiny amounts). Naturally present in food, it is also possible to increase your intake with supplements, although these should be taken with care. Excessive intake can make you ill, as the different chemical elements in your body compete with one another, and two much of one can cause a deficiency in another.
