zinc to protect your immunity system


Foods which contain Zinc

Zinc is a very significant element that is obtained from our diet. Around the world, zinc deficiency affects about 2 billion people.

Zinc is recognized to play a fundamental role in the immune system, and people who are zinc-deficient experience increased susceptibility to an array of pathogens. The immunological mechanisms whereby zinc modulates improved susceptibility to infection have been researched for several decades. It is very apparent that zinc affects several aspects of the immune system, which ranges from the skin barrier to the regulation of the genes within lymphocytes. Zinc is vital for the normal development and functioning of cells mediating non-specific immunity such as natural killer cells and neutrophils. Development of acquired immunity is also affected by zinc deficiency also. It does this by preventing both the outgrowth and certain functions of T lymphocytes such as activation, Th1 cytokine production, and also B lymphocyte help. Similarly, B lymphocyte development and antibody production, chiefly IgG, is compromised. The macrophages, which are an essential cell in many immunologic functions, are adversely affected by the deficiency of zinc, which can dysregulate intracellular killing, cytokine production, and also phagocytosis. The effects of zinc on these key immunologic mediators is entrenched in the innumerable roles for zinc in fundamental cellular functions such as DNA replication, RNA transcription, cell division, and also cell activation. Apoptosis is also potentiated by the deficiency of zinc. Zinc also functions as an antioxidant and can stabilize various membranes.

The manifestations of a moderate level deficiency of zinc include rough skin, poor appetite, mental lethargy, delayed wound healing, cell-mediated immune dysfunctions, abnormal neurosensory changes growth retardation and male hypogonadism in adolescents.

In studies that involved experimental human model in whom just a mild zinc deficiency in males was induced by dietary means, decreased natural killer (NK) cell activity, decreased serum testosterone level, oligospermia, decreased thymulin activity, decreased interleukin-2 (IL-2) production, decreased dark adaptation, hypogeusia, hyperammonemia, and decreased lean body mass were observed. It is, thus, clear that even a mild deficiency of zinc in humans affects biochemical, clinical, and immunological functions adversely.

In the developing countries, Nutritional deficiency of zinc is caused by ingestion of high cereal protein intake, rich in phytate, which makes zinc unavailable for absorption. There are many other causes of zinc deficiency that include blood loss due to hookworm infection, mal-absorption syndrome, hyperzincuria as seen in cirrhosis of the liver and sickle cell disease, and excessive sweating in hot tropical climates.

The National Institute for Nutrition (NIN), India has set the RDA (Recommended Dietary Allowance) for an adult man and NPNL (Non-Pregnant, Non-Lactating) woman for zinc at 12 and 10 mg/day respectively.
