The anaemic Class 11 student who stopped her iron tablets
Sunita is 16, in Class 11, and lives in a village near Jhansi. Her haemoglobin is 8.9 g/dL, she is 152 cm tall and weighs 42 kg. She has been vegetarian all her life, drinks two glasses of strong tea with meals, and eats fruit only when someone gives it, because 'fruit is expensive'. A normal day is three rotis with potato sabzi at 8 a.m., three rotis with thin dal at 2 p.m., and three rotis with the leftover potato at 9 p.m., plus 250 ml milk at night. The family of five has ₹9,000 a month, leaving roughly ₹35 per person per day for food. The ANM gave her iron–folic acid tablets; she stopped after a week because of black stools and constipation. Her mother wants to buy a 'tonic' instead. Sunita often skips the school midday meal to study for tests.
1. Sort the causes of Sunita's low haemoglobin into dietary, absorption-related and behavioural causes, and explain the mechanism behind each. Do not list symptoms of anaemia - explain why this diet produces it.

Dietary (what is missing)
- No haem iron at all. Plant foods carry only non-haem iron, absorbed at roughly 1–10% versus 15–35% for meat. Her intake of iron may look adequate on paper while absorbed iron is far below the RDA of about 27 mg/day for adolescent girls (ICMR).
- Iron-poor, starch-heavy plate. Potato and refined wheat dominate; there are no green leafy vegetables, no whole pulses in quantity, no jaggery, no groundnuts or sesame. Three rotis with thin dal supplies very little iron and little protein to support haemoglobin synthesis.
- No source of folate or vitamin B12 beyond 250 ml milk, so red-cell production is limited on two fronts.
Absorption-related
- Tannins in strong tea taken with meals bind iron in the gut and can cut absorption sharply; she does this at every meal.
- Phytates in whole-wheat roti and dal chelate iron. Soaking, sprouting and fermenting reduce phytates - none of these is practised.
- No vitamin C in any meal. Even the iron she does eat is not being escorted into the body; a vitamin C source at the same meal can double or triple non-haem iron absorption.
- Milk at night puts calcium close to an iron-poor meal; it matters less than the tea but adds nothing.
Behavioural
- Skipping the midday meal removes roughly a third of the day's energy, protein and iron.
- Stopping IFA after one week - the black stools and constipation are predictable, harmless side effects, not a sign of harm; one week of tablets cannot correct a deficit.
- Possible untreated hookworm or malaria and menstrual losses are not assessed, and both must be excluded before diet alone is blamed.
2. The family can add only about ₹8 per person per day. Propose a revised day's food plan for Sunita. State what you move or remove, what you add with quantity and approximate cost, and the reason each change works.

Principles I am applying: add iron-dense cheap foods, add a vitamin C source to every iron meal, separate tea and milk from iron meals, cut phytates by sprouting/soaking, and keep total extra cost near ₹8.
Changes, with reasons
| Change | Quantity / cost | Why it works |
|---|---|---|
| Move tea to 1.5 hours after meals; only 1 glass a day | saves ₹2 | Removes tannin block at the meal; saves money too |
| Add lemon or amla to the 2 p.m. dal | ½ lemon, ₹1 | Vitamin C at the same meal boosts non-haem iron absorption |
| Add a green leafy vegetable (bathua, palak, chaulai) twice a day | 100 g, ₹5 | Cheap iron, folate, and some vitamin C |
| Replace one roti at lunch with sprouted moong or chana chaat | 30 g dry weight, ₹3 | Sprouting cuts phytate, adds iron and protein |
| Swap sugar for jaggery in one meal | 10 g, ₹1 | Jaggery brings iron and some minerals |
| Keep milk at night, not with the afternoon iron meal | no cost | Avoids calcium–iron competition at the main iron meal |
| Guava or ber in season instead of 'no fruit' | 1 fruit, ₹3 | Guava is the cheapest high-vitamin-C fruit available |
Sample day: 8 a.m. - 2 rotis, bathua sabzi, 1 glass water (no tea); 11 a.m. - tea; 2 p.m. - 2 rotis, dal with lemon, sprouted moong chaat, guava; 5 p.m. - school midday meal if present; 9 p.m. - 2 rotis, vegetable, 250 ml milk; IFA tablet after dinner with lemon water.
Check the arithmetic: the additions cost about ₹9–10, offset by the tea saved and by her not buying snacks. If ₹8 is a hard ceiling, the lemon and the leafy vegetable are non-negotiable; the fruit can be seasonal and shared.
3. The mother says a tonic is better because tablets cause constipation and black stools. Write your reply as you would actually say it to her, and state what you would check before she spends money on any tonic.

What I would say to the mother
- "The black colour is iron that the body did not need, coming out in the stool. It looks frightening but it is not bleeding and not damage. If she passes hard stool, that is the iron, and we fix it with water, fibre and timing - not by stopping the tablet."
- Practical fixes: take the tablet after dinner rather than on an empty stomach, drink 8–10 glasses of water, add a vegetable and a fruit daily, and walk. Constipation usually settles in 1–2 weeks.
- "A bottle of tonic may contain a small amount of iron, a lot of sugar, and sometimes alcohol or herbs. At ₹150 a bottle she may get less iron than a ₹2 tablet, and she will finish it in ten days."
- Reframe the target: haemoglobin must rise from 8.9 to about 12 g/dL - that takes 8–12 weeks of daily iron plus diet, and then 3 more months to build stores.
What I would check before any tonic is bought
- Label: elemental iron in mg per dose (not 'ferrous sulphate 200 mg', which is only about 60 mg elemental iron); folic acid; sugar content; drug licence number or FSSAI number.
- Who is recommending it - a registered practitioner or a shopkeeper. Tonics sold as 'health supplements' are not substitutes for IFA under the national anaemia programme, which is free.
- Whether deworming has been done (albendazole in the national programme) - worms will defeat any iron given.
- Whether her periods are heavy and whether she has been screened for malaria or chronic infection, since these need treatment, not tonic.
- A repeat haemoglobin after 4 weeks to prove whatever she is taking is working; if it is not rising, the plan changes.
