People are always telling you to get enough vitamins and minerals into your diet; but do you know why you really need them? Each mineral and vitamin plays its own role within your body to nourish you and keep you healthy. Usually it is possible to get enough of these mineral and vitamins through your everyday food. However, some foods have more of them than others. When someone does not get enough of a certain vitamin or mineral, it can lead to a deficiency. For example, lack of vitamin D can cause a disease called rickets. The information below will give you a detailed look at some of the most popular vitamins and minerals (KidsHealth):
