How do high intakes of zinc affect copper absorption?

High dietary zinc intakes depress copper absorption, in- crease copper sequestration in the mucosal cell bound to MT, and increase fecal excretion of copper. Conversely, increased copper absorption has been noted in zinc-deficient animals, and high dietary copper can depress zinc absorption.
