Sources of Zinc
Zinc is present in a variety of foods that many people consume daily. The food with the most zinc per serving is oysters, but most Americans receive the greatest portion of their zinc intake from red meat and poultry. Some other food sources that contain zinc are some seafood, whole grains, fortified cereals, beans, nuts and dairy products.
The absorption of zinc tends to be higher in diets high in animal protein, as opposed to those rich in plant protein. An element present in whole grains, breads, cereals and legumes called phytate can also work to decrease zinc absorption.
