Which of the following beverages is best for increasing iron absorption during meals?

To enhance iron absorption during meals, the best choice is orange juice. This is because orange juice is rich in vitamin C, which significantly improves the absorption of non-heme iron (the type of iron found in plant foods) in the body. When vitamin C is present, it can convert iron into a form that is more easily absorbed in the intestines.

In contrast, beverages like milk, coffee, and tea can inhibit iron absorption. Milk contains calcium, which can compete with iron for absorption in the gut, while coffee and tea contain polyphenols and tannins that bind to iron and reduce its bioavailability. Therefore, consuming orange juice with meals not only provides a source of hydration but also works synergistically to enhance iron uptake, making it the optimal choice for increasing iron absorption.
