Zinc is an essential nutrient that is required for proper growth, development, and functioning of the human body. Research has found that zinc absorption can be inhibited by certain dietary elements, including high intakes of certain minerals. The most commonly identified mineral that can interfere with zinc absorption is iron.

A high intake of iron can affect zinc absorption due to competition for absorption sites in the intestine. This is because zinc is absorbed by a similar mechanism as iron, and iron can bind to the absorption site preferentially over zinc. As a result, zinc absorption can be blocked by an increased intake of iron.

In general, individuals with diets high in iron, such as those individuals with a vegan diet, are more likely to be at risk for zinc deficiency as a result of iron’s interference with zinc absorption. It is important for these individuals to ensure that they acquire enough zinc from their diet or to supplement if necessary.

Takeaways

• Zinc absorption is inhibited by an increased intake of iron.
• Individuals on a vegan diet may be at risk for zinc deficiency due to iron’s interference with zinc absorption.
• It is important to ensure that dietary zinc intakes are adequate and supplement if necessary.
