What are trace elements and minerals?

The condition of biological Essential tat for items is met if the following criteria true:

* Available in all tissues of a zoological family and regularly detectable,
* The tissue concentration from species to species should not Graven roughen differ,
* If an item, regardless of the specific species of this element deficiencies observed
* Changes in physiological and structural terms can be found on a molecular level defined biochemical defect that are
* Supply of the corresponding element of the specific deficiencies or prevents normal.

Trace elements are essential physiological importance. If they are not the body of food and drinking water fed, there will be shortages; an excessive intake may be toxic. The trace elements are assigned to all chemical elements, whose share of total body mass of less than 0.01 percent.

In the Preventive Medicine are the trace elements iron (Fe), iodine (J), copper (Cu), manganese (Mn), selenium (Se), zinc (Zn) and cobalt (Co) elementary important.

The element chromium is still a special place. Some authors classify it’s also element, but the exact mechanism of action is still unsettled. Some works have pointed out that in the glucose metabolism and acts in animal experiments enhanced chromium compounds the effects of insulin.

Quantity elements (minerals) than inorganic food components defined whose Essential tat in humans than 50 mg / day to demonstrate experimentally. In the Preventive Medicine have been particularly sodium (Na), potassium (K), magnesium (Mg), calcium (Ca) and phosphorus (P) than volume elements outstanding importance.
