Iron on a Tight Budget: Feeding a Teenager with Anaemia
Ravi and Sunita live in a rented flat with their two children and Sunita's mother. Food already takes 22% of take-home pay and the budget has been cut twice this year. Their 15-year-old daughter, Meera, was diagnosed last month with iron-deficiency anaemia (haemoglobin 9.8 g/dL) and prescribed ferrous sulphate tablets. Meera refuses red meat on taste grounds, drinks strong tea with every meal and most snacks, and describes her school lunch as 'mostly rice and peas'. Her periods are heavy. Sunita works rotating shifts and cooks in bulk twice a week; the rest of the week runs on reheated food and bread. Meera also drinks milk with her evening meal and often skips breakfast before school. The GP's leaflet says only 'eat more iron-rich foods'. Ravi wants to spend the spare cash on fortified juice and an extra iron supplement, and the family has asked for a plan they can actually keep to.
1. Sort the factors in this household into those that lower iron intake, those that lower absorption, and those that raise iron loss or demand. Then rank the three changes you would make first and justify the ranking.

Intake factors: no red meat or other heme sources; a school lunch described as mainly rice and peas, so low in both total iron and vitamin C; skipped breakfast, which removes the easiest fortified-iron opportunity of the day.
Absorption factors: strong tea with meals and snacks (polyphenols bind non-haem iron); milk with the evening meal (calcium competes with iron); no obvious vitamin C source at the main meal to convert ferric to ferrous iron.
Loss and demand factors: heavy menstrual loss - the single largest driver here - plus adolescent growth and the prescribed supplement, whose effectiveness depends on how and when it is taken.
Ranking, and why:
- Move the tea. It costs nothing, requires no shopping, and removes an inhibitor present at almost every eating occasion. Highest effect per unit of effort.
- Add a cheap vitamin C source to the cooked main meal (lemon, tomato, amla, guava, cabbage lightly cooked). This raises absorption of the plant iron the family already eats.
- Build one iron-dense item into the twice-weekly bulk cook - legumes, eggs, dark greens, or small amounts of liver or cheap cuts if acceptable - because it works with Sunita's existing routine rather than against it.
Menstrual loss is ranked separately: it needs GP follow-up (investigation and possibly treatment), not a dietary fix, and no meal plan will correct anaemia while the loss continues unchecked.
2. Design the practical changes you would make across one week, working around Sunita's bulk-cooking pattern. Explain the food science behind each change and keep cost in view.

Bulk cook (twice weekly):
- Base one pot on dried legumes or beans, soaked and boiled; add tomatoes or a squeeze of lemon at serving, not just at cooking, so vitamin C survives reheating.
- Add dark green leaves at the end of cooking rather than boiling them for an hour.
- Cook acidic dishes in a cast-iron pan where appropriate; it measurably raises the iron content of the food.
Breakfast: a fortified cereal is one of the cheapest iron-per-portion options available and needs no cooking. Pair it with fruit or juice rather than milk alone, and keep tea until mid-morning. If cost is tight, compare price per milligram of iron on the label rather than price per box.
School lunch: pack a citrus fruit or tomato-based side to eat with the rice and peas, and replace the tea flask with water.
Evening meal: shift milk to a snack or to bedtime, well away from the iron-containing meal.
Supplement timing: ferrous sulphate is best absorbed on an empty stomach with vitamin C, but if it causes nausea, take it with a small amount of food - not with tea, milk, or the evening meal. Keep the prescription dose.
Monitoring: repeat haemoglobin at the interval the GP advises (commonly 8–12 weeks), keep a simple two-week food and tea diary, and record fatigue and period heaviness. If haemoglobin has not risen, the diet is not the limiting factor and the loss must be investigated.
3. Ravi proposes buying fortified juice and an additional over-the-counter iron supplement alongside the prescription. How would you respond, and where should the spare money go instead?
Read the worked answer
On the extra supplement: this is the one part of the plan to refuse. Meera is already on prescribed ferrous sulphate; adding an over-the-counter iron product stacks doses and raises the risk of gastrointestinal upset, constipation, and - in overdose, particularly in children - serious toxicity. Iron is a drug with a narrow margin, not a vitamin to top up. The right move is to make the prescribed dose work: correct timing, away from tea and calcium, with vitamin C, and a repeat blood test to show whether it is working.
On fortified juice: it does contain vitamin C and some iron, but check the price per milligram of iron and per portion of sugar. Juice is a useful absorption aid; it is an expensive iron source, and it does not replace the tea at mealtimes, which is the bigger problem.
Better uses of the spare money, in order:
- A fortified breakfast cereal eaten most days, judged on iron per portion per unit cost.
- Eggs, legumes, and dark green vegetables in the bulk cook.
- A second citrus or tomato item for packed lunches.
Framing for the family: the free changes (tea timing, vitamin C at meals, milk away from meals) come first because they cost nothing and act immediately. Spending comes second. The blood test comes third and settles whether the plan is working - the family should not have to guess.
