Minerals and Trace Elements
Minerals and trace elements are essential for a person’s normal physical and mental development. Adequate levels of these essential elements are vital for body functions.
Minerals are found in the body at a concentration of 50 mg per kilogram of body weight. These minerals include chloride, potassium, calcium, magnesium, sodium and phosphorus.
Trace elements are in the body in smaller amounts than 50 mg per kilogram of body weight. These trace elements include arsenic, lead, chromium, iron, fluorine, iodine, cobalt, copper, magnesium, molybdenum, nickel, selenium, silicon, vanadium, zinc and tin.

How do I take care of meeting my daily mineral requirements?
In contrast to vitamins, most minerals are not very sensitive to heat, light and oxygen. However, they can be leached out in water (during food preparation, washing and cooking).
Here are some best practice tips:
- Wash whole vegetables and fruit as well as possible, prior to preparation
- Steam or cook vegetables in as little water as possible
- Many minerals are present in the skin of vegetables and fruit. Therefore, consume unpeeled fruit or vegetables whenever possible.
