Which of the following food items is NOT suitable for a client with iron deficiency anemia?

Dairy products are not considered suitable for a client with iron deficiency anemia due to their high calcium content, which can interfere with the absorption of iron. Calcium competes with iron for absorption in the intestines, potentially reducing the effectiveness of iron supplements or dietary iron intake, making it more challenging for someone with iron deficiency anemia to improve their iron levels.

On the other hand, foods like quinoa, liver, and spinach are all good sources of iron. Quinoa is a plant-based source of iron, liver is exceptionally rich in heme iron (the form of iron most easily absorbed by the body), and spinach contains non-heme iron, although it's worth noting that its absorption can be enhanced when consumed with vitamin C-rich foods. In contrast, dairy products do not provide significant amounts of iron and can hinder the absorption of this essential mineral, making them less suitable for individuals needing to boost their iron levels.
