This mineral is found in all the cells of our body, but in very little quantity.
In the decade of the 1960 it was shown that this mineral was essential for the human being, that is, essential for life.
Zinc for children’s growth
In the 1920s, scientific studies began to show the importance of this mineral for the development and growth of the human being.
Zinc is involved in the formation and mineralization of bone and reproductive organs. Deficiency of this mineral is associated with a growth retardation in children.
In the treatment of osteoporosis, zinc is a mineral recommended to increase bone mineralization along with other important minerals such as calcium, copper and manganese. In some cases zinc supplements are given for non-tartar teeth.
Functions of zinc in the body
This mineral collaborates in many routes of the metabolism since it constitutes a numerous group of enzymes. Zinc is involved in different metabolic processes of our body, such as the manufacture of DNA or genetic material, and in the metabolism of proteins.
For example, an enzyme formed by zinc (called alcohol dehydrogenase), is responsible for metabolizing toxins in our body, as the alcohol, so as to be eliminated. For this reason, people with alcoholism, cirrhosis or alcoholic liver disease can develop a long-term deficit of this mineral due to its excessive consumption.
For the same reason, zinc is a very important mineral for reproduction and fertility.
Zinc for prostate
Zinc inhibits the production of dihydrotestosterone, a testosterone derivative whose high levels are related to non-cancerous enlargement of the prostate (benign prostatic hyperplasia) and to alopecia or male pattern baldness. Correct levels of zinc can help maintain health preventing some prostate problems.
Main properties of the mineral zinc and foods containing it.
