Zinc-Rich Foods

Zinc-Rich foods can enhance immunity functioning. This mineral helps increase many aspects of immunity, including production of antibodies and T-cells, as well as other white-blood-cell activity. It has been shown in experiments on animals that when they are deficient in zinc, they cannot fight off attacks by bacteria, viruses and parasites. It has also been observed that adults and children deficient in zinc, often have more cols and respiratory tract infections.

According to Dr. Novera H. Spector, a scientist at the American National Institute of Health, Zinc may even rejuvenate an aging immune system. He explains that zinc may help reverse declining immune functions that deteriorates rapidly after the age of 60 years. After the middle age, the thymus gland, which plays a key role in immune defenses, begins to decline radically. The thymus gland secretes thymulin, a harmone that stimulates production of T-cells. With the decline o thymus gland, the output of thymulin also decreases.
