input: [Nutrient] Zinc [Notes] 
output: Zinc is also more bioavailable in animal forms (especially oysters and crab) since plant phytates can bind both zinc and iron. Anything that lessens phytate content will help zinc absorption from plants. For instance, yeast-leavened breads and sprouting beans, grains, and seeds will improve zinc bioavailability. Try to eat a variety of plant sources of zinc. Ask your doctor about zinc if you are taking iron supplements as it can interfere with zinc absorption.
