Dietary minerals are important constituents of bones, teeth, muscle, blood, tissues and nerve cells. They can be found in a variety of foods, including dairy, meat, cereal products, vegetables, fruit and nuts.
There are two kinds of minerals: macrominerals and trace minerals. Macro means "large" in Greek and macro minerals are needed by the body in larger amounts than trace minerals. The macromineral group is made up of calcium, phosphorus, magnesium, sodium, potassium, chloride and sulphur.
Trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium and are only needed in small amounts.
