Zinc is an essential mineral forming a component of more than 300 enzymes in the body with functions including wound healing, immune system function, building proteins and DNA, fertility in adults and growth in children. Zinc is also needed for maintaining the senses of smell and taste.

A deficiency in zinc can lead to stunted growth, diarrhea, impotence, hair loss, eye and skin lesions, impaired appetite, and depressed immunity.

Conversely, consuming too much zinc can disrupt the absorption of copper and iron, as well as creating large amounts of toxic free radicals. It is easier to over-consume zinc from animal foods and supplements, from which it is more readily absorbed.

Vegans and vegetarians who primarily consume plant foods may have difficulty getting enough zinc, as zinc is not as bioavailable in plant foods as in animal foods. This is partly because beans and legumes contain phytates which can inhibit absorption. Despite this, plant foods are still a good source of zinc and there is no reason to eat meat or take a supplement.

The current daily value (DV) for zinc is 11mg, but vegetarians and vegans should aim to eat 30mg a day. Vegetables high in zinc include shiitake mushrooms, green peas, spinach, lima beans, lentil sprouts, asparagus, beet greens, broccoli, okra, and sweet corn.
