Why is vitamin C-rich food considered helpful in iron absorption?

Correct answer: It can support the absorption and use of some iron

Vitamin C improves the absorption of non-haem iron, the form commonly found in plant foods such as pulses, cereals, and leafy vegetables. It helps convert iron into a form that the intestine can absorb more readily. This is why lemon, amla, guava, or other vitamin C-rich foods may be eaten with iron-containing meals. It does not remove iron, add salt, or destroy calcium.
