Question:

How does one's iron status impact the absorption of iron? Provide an example of an individual who would experience increased iron absorption.

Answer:

An individuals iron absorption status can impact how much iron is being absorbed at a given time. Because iron can be stored, the body can use it's stored iron supply when it's in a deficiency and in need of iron. For example, pregnant women are often iron deficient and their body has increased iron absorption, causing a need for more iron absorption. When an individual is iron deficient, they need more iron through dietary intake than individuals who are not.
