Foods high in Zinc
Trace mineral for immune function, wound healing, and sense of taste. Best absorbed from animal foods; phytates in grains reduce uptake.
About Zinc
Zinc is required for over 300 enzymes, supports the immune system, drives wound healing, and is needed for the senses of taste and smell. It also plays a structural role in many proteins.
Densest sources are oysters (by a wide margin), red meat, poultry, beans, nuts, and whole grains. Phytates in grains and legumes bind zinc and reduce absorption; soaking, sprouting, and fermenting (sourdough is a good example) cut phytate content and improve uptake.
UK adult RI: 10 mg/day. Deficiency reduces immune function and can impair growth in children. Long-term supplementation above 50 mg/day disrupts copper absorption, high-dose zinc isn't a free hit.
