Which food is recommended for a client taking an iron supplement?

Citrus foods are recommended for a client taking an iron supplement because they are high in vitamin C, which enhances the absorption of non-heme iron (the type of iron found in plant-based foods and iron supplements) in the digestive system. Consuming vitamin C-rich foods alongside iron supplements can significantly improve the body’s ability to absorb iron, helping to effectively increase iron levels, particularly for those who may be prone to anemia or iron deficiency.

In contrast, while whole grains and dairy products contain important nutrients, they are not particularly beneficial for iron absorption. Whole grains can contain phytates that may inhibit iron absorption, and dairy products are high in calcium, which can interfere with the absorption of iron when consumed in the same meal. Red meat is a source of heme iron, which is more readily absorbed by the body than non-heme iron, but it may not be the appropriate recommendation specifically for someone already taking an iron supplement focused on enhancing absorption through dietary means. Thus, citrus foods are the most suitable choice in this context.
