Trace elements are minerals that humans need for the organism to function properly. However, he needs them only in traces (less than 20 milligrams per kilogram of body weight daily). They are present in food and water. Among the most important are chromium, cobalt, iron, iodine, copper, manganese, selenium and zinc.
Essential trace elements
The essential microelements are components of enzymes, hormones and hemoglobin. Iodine is important for the thyroid gland, zinc for the immune system and iron for blood formation. Manganese is needed by humans to form connective tissue, selenium is a radical scavenger and copper is used for iron metabolism and is important for the nervous system.
The right supply
If these substances are missing in the body, deficiency symptoms occur. The most common is iron deficiency, which leads to anemia. Iodine deficiency results in metabolic disorders. If a person ingests too much of microelements, it can lead to symptoms of poisoning, diarrhea or the formation of kidney stones.
Deficiency often not obvious
Trace elements are needed by everyone, but only in small amounts that should not be exceeded. A deficiency often manifests itself in poor sleep or brittle fingernails. In this case, the doctor should be consulted for advice. Likewise, when dieting, before someone resorts to supplements to make up for any deficiency. By means of a blood test, this person can determine whether a deficiency is present.
