Which would aid the absorption of an iron supplement?

Orange juice and hamburger are particularly effective in aiding the absorption of an iron supplement due to their specific nutrient content. Orange juice is rich in vitamin C, which significantly enhances the absorption of non-heme iron, the type commonly found in plant-based sources and iron supplements. The presence of vitamin C helps convert iron into a more soluble form, making it easier for the body to absorb.

Hamburger, typically a source of heme iron, is also beneficial because heme iron is absorbed more efficiently by the body compared to non-heme iron. Consuming a source of heme iron alongside a non-heme iron supplement can further improve the overall absorption of iron.

Combining these two foods—orange juice providing vitamin C and hamburger containing heme iron—makes this choice particularly effective for improving iron absorption.
