The Pale Class XI Girl Who Drinks Tea With Every Meal
Priya, a 15-year-old studying in Class XI at a government higher secondary school in Salem, is sent to the school health clinic because she keeps sitting out of physical education. Her haemoglobin is 8.4 g/dL. She is pale, tires within ten minutes of any activity, and has started skipping lunch because she feels too tired to eat. Her mother says the family is vegetarian by tradition, though eggs appear occasionally. The staple is rice with sambar, twice a day. Priya drinks strong tea with almost every meal and one large cup at midnight while studying. Her three-day diet record shows about 40 g of dal and 30 g of greens on a good day, almost no fruit, and no sprouted or fermented foods except idli twice a week. Her periods last six days and are heavy. The doctor has prescribed iron-folic acid tablets, but Priya takes them irregularly because they give her stomach pain, and she usually swallows them on an empty stomach with tea.
1. List the dietary and physiological factors that together explain Priya's haemoglobin of 8.4 g/dL, and state which of them a dietitian can actually change.

Physiological, non-dietary factors
- Heavy menstrual bleeding for six days is a recurring iron loss that no diet alone can fully offset; this needs medical review, not just counselling.
- Adolescent growth spurt raises iron requirement sharply at the same time.
Dietary factors
- Low absolute iron intake: 40 g dal and 30 g greens supply only a few milligrams of iron, and almost no fruit means no vitamin C.
- Poor bioavailability: a rice-dominant diet is high in phytates, and tea taken with meals adds tannins that can cut non-haem iron absorption by roughly half or more. Non-haem iron from cereals and pulses is only about 1-10% absorbed, so tea at every meal matters more than the total intake figure suggests.
- No flesh foods except occasional egg, so almost no well-absorbed haem iron.
- No sprouting or fermentation on most days, so phytate is not being reduced.
Changeable by diet counselling: tea timing, vitamin C at meals, quantity and type of pulses and greens, sprouting and fermentation, egg frequency. Not changeable by diet alone: menstrual loss (needs referral) and tablet adherence (needs the prescriber's help). The judgement point is that counselling on tea and vitamin C will achieve little if the bleeding and the irregular tablets are not addressed at the same time.
2. Priya's tablet is a weekly 60 mg elemental iron plus 500 micrograms folic acid preparation. Explain why it upsets her stomach and how her routine should be adjusted so that it is both tolerated and absorbed.

Why it hurts: elemental iron salts are irritant to gastric mucosa and are the commonest cause of nausea, epigastric pain and constipation at this dose. Taking it on an empty stomach with strong tea makes both problems worse: the tea tannins reduce absorption, so she gets the side-effects without the benefit, and the fasting state increases nausea.
Practical adjustment, with the reasoning for each step
- Timing: take the tablet at bedtime, after the evening meal, rather than in the morning. Nausea is then slept off and the tablet is not competing with a meal's phytates.
- What to take it with: water, or lemon water, or a piece of guava or amla. Vitamin C in the same sitting converts ferric to ferrous iron and can several-fold increase non-haem absorption.
- What to keep away from: tea, coffee, milk, curd, calcium supplements and antacids, ideally for an hour before and two hours after the dose.
- Warn her in advance about black stools, so she does not stop the tablet in alarm.
- Escalate if needed: if pain persists despite these changes, the prescriber may need to know - but she should not silently stop, because at Hb 8.4 g/dL the deficit cannot be closed by food in a reasonable time.
Note the distinction the question is testing: the weekly dose is a prophylactic schedule; a girl with Hb 8.4 g/dL is in the treatment category and her regimen should be confirmed by the medical officer, not assumed from the packet.
3. Construct a one-day vegetarian-plus-egg menu for Priya using foods available in a Tamil Nadu village market, and justify three specific choices in terms of iron absorption rather than just iron content.

Menu
- Early morning: lemon water; 4-5 soaked almonds (not a tea-substitute ritual).
- Breakfast: two ragi dosas with a side of sprouted green gram sundal; one guava.
- Mid-morning: water or buttermilk - tea only here, at least an hour away from the main iron meals.
- Lunch: rice with drumstick-leaf kootu (about 50 g greens), sambar with 40 g dal, a lemon wedge squeezed over the kootu, and a small boiled egg.
- Evening: idli (fermented) with a tomato chutney; avoid the midnight tea habit.
- Dinner: ragi kali or rice with a pulse-based kuzhambu and a second green vegetable; a piece of jaggery only if it replaces sugar, not as an iron 'remedy'.
Justification of three choices
- Lemon over the greens: the vitamin C converts and solubilises non-haem iron in the same meal; without it, the drumstick leaves contribute iron that is largely unabsorbed.
- Sprouting and fermenting: sprouted gram and fermented idli batter reduce phytate, which is the main inhibitor in a rice-and-dal diet. The gain is from absorption, not from extra iron in the food.
- Tea moved away from meals: shifting tea to a mid-morning slot removes tannin inhibition from the two iron-dense meals while keeping the habit she will actually follow.
Additions a dietitian should flag: the menu increases vitamin C, phytate reduction and haem iron, but it cannot compensate for six days of heavy bleeding - so this plan must run alongside the tablet and a medical review.
