minerals

Minerals are inorganic nutrients which the body cannot produce itself which must therefore be ingested in food. They play an important role in the body including the growth of body tissues (e.g. bones, cells) and regulation of metabolism. Minerals are classified as: 

  • major elements: more than 50 mg per kg body weight (e.g. calcium, magnesium, sodium, phosphorus)
  • trace elements: less than 50 mg per kg body weight (e.g. iron fluorine, iodine, zinc).
