The Body - Minerals defined

Dietary minerals are chemical elements required by living organisms. They can be either bulk minerals (required in relatively large amounts) or trace minerals (required only in very small amounts).

Appropriate intake levels of each dietary mineral must be sustained to maintain physical health. Excessive intake of a dietary mineral may either lead to illness directly or indirectly because of the competitive nature between mineral levels in the body. For example, large doses of zinc are not really harmful unto themselves, but will lead to a harmful copper deficiency (unless compensated for, as in the Age-Related Eye Disease Study).

Soils in different geographic areas contain varying quantities of minerals.

In humans the most important dietry minerals are:

  • chromium
  • copper
  • fluorine
  • iodine
  • iron
  • magnesium
  • manganese
  • molybdenum
  • potassium
  • selenium
  • zinc

Secondary dietry minerals are defined below. Not all have been definitively established as essential to human nutrition:

  • arsenic
  • bismuth
  • boron
  • nickel
  • rubidium
  • silicon
  • strontium
  • tellurium
  • titanium
  • tungsten
  • vanadium
