Zinc

Zinc is an essential nutrient, required for numerous metabolic functions, including gene expression, growth and immunity. Manifestations of zinc deficiency include growth retardation, high rates of infection, skin lesions and impaired wound healing. Zinc deficiency is a major contributor to the burden of disease in developing countries. Seafood and red meat are good sources of bioavailable zinc. Dietary zinc from plant sources is less bioavailable due to the interaction with phytate. The recommended dietary intake for zinc is 8 and 14 mg/day for women and men, respectively. The Dietary Guidelines for Australian Adults identify red meat as a substantial source of zinc.
