A nurse is instructing a group of clients about nutrition and eating foods high in iron. The nurse should include that which of the following aids in the absorption of iron?
Vitamin C
Oxalates
Fiber
Vitamin A
The Correct Answer is A
A. Vitamin C enhances the absorption of non-heme iron from plant-based sources by converting iron to a more absorbable form. Including vitamin C-rich foods with iron-rich meals can improve iron uptake.
B. Oxalates, found in foods like spinach and rhubarb, can inhibit iron absorption by binding to iron and reducing its availability.
C. Fiber, while beneficial for digestive health, does not enhance iron absorption and can, in some cases, inhibit it by binding to minerals.
D. Vitamin A does not have a direct role in the absorption of iron, though it is essential for overall health.
