ZINC…..This valuable mineral increases the production of white blood cells that fight infection and helps your white blood cells to fight more aggressively. It also increases killer cells that fight against cancer and helps white cells release more antibodies. Zinc supplements have been shown to slow the growth of cancer!
Zinc increases the number of infection-fighting T-cells, especially in elderly people who are often deficient in zinc, and whose immune system often weakens with age.
The anti-infection hype around zinc is controversial. While some studies claim that zinc supplements in the form of lozenges can lower the incidence and severity of infections, other studies have failed to show this correlation. A word of caution: too much zinc in the form of supplements (more than 75 milligrams a day) can inhibit immune function. It’s safest to stick to getting zinc from your diet and aim for 15 to 25 milligrams a day.
For infants and children, there is some evidence that dietary zinc supplements may reduce the incidence of acute respiratory infections, but this is controversial. The best source of zinc for infants and young children is zinc-fortified cereals.
