Nutritional Facts on Zinc

Zinc is an essential mineral that is found in almost every cell. It stimulates the activity of approximately 100 enzymes, which are substances that promote biochemical reactions in the body. Zinc supports immunity; is needed for wound healing; helps maintain the sense of taste and smell; is needed for deoxyribonucleic acid synthesis; and supports normal growth and development during pregnancy, childhood, and adolescence.

Zinc is found in a wide variety of foods. Atlantic oysters contain more zinc per serving than any other food, but red meat and poultry provide the majority of zinc in the American diet. Other good food sources include beans, nuts, certain seafood, whole grains, fortified breakfast cereals, and dairy products. Because zinc absorption is greater from a diet high in animal protein than a diet rich in plant proteins, vegetarians may become deficient if they are not monitored carefully. Phytates from whole-grain breads, cereals, legumes, and other products can decrease zinc absorption.
