Which food is rich in iron?

• A. Spinach
• B. Beans
• C. Oranges
• D. Milk

Answer: (A)

Iron-rich foods provide the mineral needed for forming hemoglobin and transporting oxygen in the blood. Spinach stands out as a strong plant-based source of iron, delivering a meaningful amount of non-heme iron per serving. While non-heme iron isn’t absorbed as efficiently as heme iron from animal foods, its uptake can be boosted by pairing with vitamin C-rich foods and by cooking to reduce absorption-inhibiting compounds like oxalates found in leafy greens. The other options don’t supply iron in meaningful amounts: oranges are high in vitamin C but not in iron, milk provides little iron and can hinder absorption because of calcium, and beans do contain iron but spinach is a more prominent example of an iron-rich plant option in this set.
