The mineral zinc is very important for many of the enzyme systems in the body, for immunity and for the production of hormones, including insulin and sex hormones. Zinc in plant foods is less bioavailable that in animal foods because it binds to phytate (a fibre) that makes it difficult to absorb. Zinc also competes with calcium and iron for absorption.
