Ravi's Tiredness: Reading a Dietary Pattern and Planning Within ₹40 a Day
Ravi is 15 years old, 160 cm tall and weighs 48 kg. He is in Class 10 and wants a place in the school cricket team, but he is exhausted after ten minutes of play. He gets up at 5:30 a.m. and has only tea with two biscuits before school. At the 10 a.m. break he buys a samosa or a packet of chips from the canteen. He reaches home at 4 p.m. and eats rice with thin dal, then has tea again. Dinner is usually two rotis with potato curry. He refuses all green leafy vegetables and eats no fruit. Tea is taken four times a day, always with meals. He has had three colds this winter and cannot concentrate in the last two periods. A doctor's slip shows haemoglobin 9.5 g/dL. The family has five members and a food budget of about ₹6,000 a month.
1. Name the most likely nutritional problem and support it with three pieces of evidence from the case. Calculate his BMI and decide whether his weight is also a concern.
Read the worked answer
Most likely problem: iron-deficiency anaemia, with a generally poor diet quality behind it.
Evidence:
- Haemoglobin 9.5 g/dL, which is well below the roughly 12–13 g/dL taken as normal at his age - this is the confirming laboratory sign, not a complaint.
- The dietary pattern supplies almost no iron and no vitamin C. Sattu, dal, green leafy vegetables and jaggery - the cheap iron foods - are missing; leafy vegetables are refused and there is no fruit at all. At the same time, tea four times a day with meals adds tannins that bind iron in the gut and cut its absorption.
- The symptoms fit the deficiency: tiring after ten minutes, repeated colds (immunity suffers in anaemia), and loss of concentration in the last two periods, which also reflects a long gap without food after a biscuit breakfast.
BMI = 48 ÷ (1.60 × 1.60) = 48 ÷ 2.56 ≈ 18.8. For a 15-year-old boy this sits at the lower edge of the normal band - he is not wasted, but he is not carrying any reserve either. His weight is a secondary concern, not the diagnosis: the priority is iron, protein and a regular meal pattern, and weight will follow once he eats three proper meals. The interpretation matters - treating this as 'just weakness' or as 'he needs to eat more' misses both the deficient nutrient and the tea habit that is blocking it.
2. Plan one day's meals for Ravi costing about ₹40, using cheap local foods. For each meal, state which iron source it carries and how absorption is protected or improved.
Read the worked answer
The plan follows three rules: put an iron source in at least three meals; put a vitamin C source in the same meal as the iron; and move tea at least an hour away from food.
| Time | Meal | Iron and absorption logic | Approx. cost |
|---|---|---|---|
| 6:15 a.m. | 2 rotis + sattu drink (30 g gram flour, salt, lemon) + 10 g jaggery | Sattu and jaggery are non-haem iron; the lemon supplies vitamin C in the same meal, converting ferric to the better-absorbed ferrous form | ₹8 |
| 10 a.m. tiffin | Roasted chana 30 g + 1 guava (or groundnut chikki) | Chana and groundnut add iron and protein; guava is a cheap high-vitamin-C fruit | ₹6 |
| 1 p.m. lunch box | 3 rotis + amaranth or spinach sabzi (100 g) + lemon wedge | Leafy vegetables are the cheapest iron-rich food; cooking with a little oil and adding lemon raises absorption; packing a box removes the samosa-and-chips habit | ₹10 |
| 4 p.m. | Rice + 40 g dal + lemon; tea only after 5 p.m., maximum two cups | Dal adds iron and protein; the 4 p.m. meal replaces the present single meal and closes the long hunger gap | ₹8 |
| 8 p.m. dinner | 2 rotis + seasonal vegetable + 1 egg (or 30 g groundnut) | Egg supplies haem iron, which is absorbed better than any plant source | ₹8 |
Total ≈ ₹40. The reasoning is not just 'eat iron' - it is pairing. The lemon and guava are as important as the spinach, because plant iron is poorly absorbed on its own. Tea is shifted to the gap between meals, not served with them, and milk or curd is kept for the evening rather than poured over an iron meal, since calcium competes with iron. Spices and the pressure-cooking of dal are irrelevant here; cooking in an iron kadhai would add a small bonus only.
3. The mother says she will give him the prescribed iron tablet with his morning tea and milk because 'it will be easy to swallow'. Explain why this is a poor choice and what she should do instead.
Read the worked answer
Tea contains tannins (polyphenols) that bind iron in the intestine and can cut absorption of a tablet substantially, and the calcium in milk forms an insoluble complex with iron - the two together could waste most of the dose even if the tablet is swallowed obediently. Ease of swallowing is not the goal; absorbed iron is.
What she should do:
- Give the tablet with lemon water, amla or orange, not tea or milk - vitamin C in the same swallow improves absorption.
- Keep a gap of at least one hour on either side between the tablet and tea, milk, curd, or any calcium supplement.
- Ideally give it on a relatively empty stomach about an hour before a meal; if it causes nausea or stomach pain, give it with a small meal that contains no tea or milk.
- Warn the family that black stools are normal and that constipation is common, so water, fruit and fibre must go up.
- Continue for the full course the doctor prescribed, and get haemoglobin rechecked rather than stopping when he 'feels better' - the stores refill long after the tiredness lifts.
The reasoning to teach the family: a supplement is not magic, it is a dose that must survive the trip through the gut, and the drink taken with it decides how much survives.
