What are dietary minerals (elements)? Besides four basic elements – hydrogen, carbon, nitrogen and oxygen from which all organic matters are created – there are chemical elements, which play a highly important role in biochemical and physiological processes of our body. More than 20 chemical elements are required for proper body functioning- this group of chemical elements is called “dietary minerals”. Dietary minerals must be consumed with food or supplements always in appropriate quantity. Shortage or exaggerated consumption may be harmful.
