Zinc, an essential trace element, is found in cells throughout the body and helps the immune system by fighting off bacteria and viruses. It is also involved in making proteins and DNA and helps wounds heal, among other functions. Oysters are the richest source of zinc, and other good sources include red meat, poultry, crab, lobsters, and fortified cereals.
