What beverage should a patient who is iron-deficient consume with a good iron source?

The correct answer is orange juice because it is high in vitamin C, which plays a crucial role in enhancing the absorption of non-heme iron (the type of iron primarily found in plant-based food sources). Consuming vitamin C-rich foods or beverages alongside iron-rich foods can significantly increase the amount of iron that the body can absorb. This is particularly important for individuals with iron deficiency, as maximizing iron absorption is essential for addressing their nutritional needs effectively.

In contrast, options like apple juice, milk, and cheese do not provide the same beneficial effect when it comes to iron absorption. While apple juice may have some vitamins and minerals, it does not contain vitamin C in significant amounts compared to orange juice. Milk and cheese contain calcium, which can actually inhibit iron absorption if consumed at the same time as iron-rich foods. Thus, for a patient who is iron-deficient, orange juice is the optimal choice to promote better iron absorption.
