Iron Deficiency Anaemia India 2026 | NFHS Data | Iron-Rich Foods | AaharIQ

India's anaemia burden increased between NFHS-4 and NFHS-5 — getting worse despite government supplementation programmes (Anaemia Mukt Bharat, mid-day meal iron fortification). This suggests the dietary pattern driving anaemia is not being adequately addressed by supplementation alone.

There are two forms of dietary iron: haem iron (from animal sources, 15–35% absorption) and non-haem iron (from plant sources, 2–20% absorption, highly variable). The predominantly vegetarian Indian diet relies almost entirely on non-haem iron — which is dramatically affected by what is consumed alongside it:

Vitamin C (ascorbic acid) is the most potent enhancer of non-haem iron absorption — it can increase non-haem iron absorption by 2–6 fold when consumed in the same meal. For vegetarian and vegan Indians relying on plant-based iron, this combination is not optional — it is essential:

• Lemon juice squeezed on dal: This classic Indian combination is nutritionally optimal — the vitamin C in lemon (50–60mg per tablespoon fresh juice) 3–6× enhances iron absorption from the dal.

• Amla (fresh or dried) with iron-rich foods: Amla provides 600–700mg Vitamin C per 100g — the highest of any Indian food. Even a small piece (10–15g) provides enough Vitamin C to significantly enhance iron absorption from the same meal.

• Tomato in sabzi with iron-rich greens: Fresh tomato provides 20–25mg Vitamin C — a meaningful iron absorption enhancer when combined with iron-rich leafy greens.

• Green chilli in dal: One green chilli provides 100–150mg Vitamin C — a natural enhancement of iron absorption in the same dish.

AaharIQ identifies iron-fortified packaged foods (where manufacturers have added iron) and distinguishes between products using bioavailable iron forms (ferrous sulphate, ferrous fumarate — well absorbed) and poorly bioavailable forms (ferric orthophosphate, elemental iron — poorly absorbed and often used to inflate label iron numbers). AaharIQ also flags the presence of major iron blockers — specifically the tea and coffee content in packaged "health drinks" that are simultaneously marketed for iron content while containing tannins that block its absorption.

The Anaemia Mukt Bharat programme distributes iron supplements nationwide, yet anaemia is worsening. The reason: iron supplements without Vitamin C-rich foods in the same meal are poorly absorbed; and daily chai consumed with iron-rich meals blocks 60–90% of dietary iron absorption regardless of supplementation. Dietary pattern change, not supplementation alone, is the solution.
