Zinc is an essential microelement, which is necessary for all living organisms and their biological processes. The body’s need for this microelement is high, with only iron needed in greater amounts. The main dietary sources of zinc are beef, poultry, seafood and cereals. In the case of a poor diet and alcohol abuse, the possibility of a zinc deficiency in the body increases.
- Zinc is an essential microelement for normal metabolism and is involved in the catalysis of more than 300 enzymes needed for various biochemical reactions in the body.
- In the 1960s, it was found that a sufficient zinc intake is essential for the normal functioning of the immune system. Zinc ions are involved in the regulation of signal transductions between different cells in the immune system. This microelement is important to ensure that the bone marrow contains sufficient numbers of B-cell and T-cell precursors. The zinc-dependent enzyme thymulin promotes the development of T-cells in the thymus gland. Zinc is also important for the production of cytokines in the mononuclear cells and the normal functioning of the NK (natural killer) cells.
- Studies show that increased cytokine production and zinc deficiency can lead to increased levels of harmful free radicals, but zinc supplements will help to protect the cells from oxidative stress.
