3.4 Micronutrients — Vitamins and Minerals
In Part 1 we learnt about big nutrients like carbohydrates, proteins and fats. Our body also needs tiny amounts of very special nutrients called vitamins and minerals. Though tiny, they are essential — without them we fall sick, even if we eat lots of rice and dal!
🧠 Why "micro"? We need them in very small quantities — often just a few milligrams a day. But without them, our body cannot function properly.
The Main Vitamins 🌈
| Vitamin | What it does | Food Sources | Deficiency Disease |
|---|---|---|---|
| Vitamin A 👁️ | Keeps eyes & skin healthy | Papaya, carrot, mango, milk, green leafy vegetables | Night blindness — trouble seeing in dim light |
| Vitamin B₁ ⚡ | Helps body get energy from food; keeps nerves healthy | Legumes, nuts, whole grains, seeds, milk products | Beriberi — swelling, tingling, burning in feet |
| Vitamin C 🍊 | Helps body fight diseases and heal wounds | Amla, guava, green chilli, orange, lemon, tomato | Scurvy — bleeding gums, slow wound healing |
| Vitamin D ☀️ | Helps bones absorb calcium — for strong bones | Sunlight on skin, milk, butter, fish, eggs | Rickets — soft, bent bones |
🌞 Sunshine vitamin: Vitamin D is the ONLY vitamin our body can make on its own — our skin makes it when sunlight falls on it. 15 minutes of morning sun = free vitamin D!
The Main Minerals 🧱
| Mineral | What it does | Food Sources | Deficiency Disease |
|---|---|---|---|
| Calcium 🦴 | Builds strong bones & teeth | Milk, curd, cheese, paneer, ragi | Weak bones, tooth decay |
| Iodine 🧠 | Needed for physical and mental activity (thyroid hormone) | Seaweed, singhada (water chestnut), iodised salt | Goitre — swelling in front of neck |
| Iron 🩸 | Important part of blood (haemoglobin) — carries oxygen | Green leafy vegetables, beetroot, pomegranate, jaggery | Anaemia — weakness, shortness of breath |
🧂 Use iodised salt: By law, most packed salt in India has iodine added — this simple change has dramatically reduced goitre in the country. Always check "iodised" on the pack!
🔬 Activity — Match the Deficiency L2
Match each person's complaint with the likely missing nutrient:
| Complaint | Missing Nutrient? |
|---|---|
| Riya can't see well in the evening. | ? |
| Aman's gums bleed when brushing. | ? |
| Noor's neck has a swelling in front. | ? |
| Dev feels tired and short of breath. | ? |
🤔 Predict: Write your answers before peeking!
Riya — Vitamin A (night blindness). Aman — Vitamin C (scurvy). Noor — Iodine (goitre). Dev — Iron (anaemia).
3.5 A Balanced Diet ⚖️
If you eat only rice, you get energy but no protein, vitamins or minerals. If you eat only sweets, you get lots of sugar but little of everything else. A balanced diet is one that has all the nutrients in the right proportions.
🍽️ A balanced diet = Carbohydrates + Proteins + Fats + Vitamins + Minerals + Water + Dietary Fibre — all together, every day.
How much of each nutrient we need depends on:
- Age: A growing Grade 6 child needs more protein than a grandparent.
- Activity: A kabaddi player needs more energy food than someone who mostly studies.
- Health: When you are ill, you need more fluids and certain vitamins.
- Weather: In summer we need more water; in winter, more warm foods.
The Wisdom of Seasonal, Local Foods 🌱
Our grandparents knew what modern science now confirms: foods grown in your own region, in their natural season, are tastiest and most nutritious. They are also cheaper, and travel shorter distances (you'll learn about food miles in Part 3!).

🤔 Target: Carbs + Protein + Vitamin + Mineral + Fibre + Water/fluid
Sample: 2 vegetable parathas (carbs + fibre) stuffed with paneer (protein + calcium) and grated carrot (vitamin A), a small bowl of curd (calcium), a banana (fibre + potassium), and a bottle of water. Simple, tasty, balanced!
🧠 Competency-Based Questions
Ravi's family members all have different complaints. Ravi's mother has weak bones; his father's neck has a swelling in front; his grandmother's gums bleed; his younger sister Meena has trouble seeing in dim light; Ravi himself feels tired and short of breath after running.
Q1. Which nutrient is likely missing in Ravi's mother's diet? L3
C — Calcium (often with Vitamin D). Weak bones come from lack of calcium, which builds bones.
Q2. Meena's night-vision problem is caused by deficiency of: L1
A — Vitamin A. Deficiency causes night blindness. Carrots, papaya and leafy vegetables are rich sources.
Q3. Suggest ONE food item each that will help each family member. L3
Mother — milk/paneer (calcium); Father — iodised salt/water-chestnut (iodine, for goitre); Grandmother — amla/orange (vitamin C); Meena — carrot/papaya (vitamin A); Ravi — spinach/jaggery/pomegranate (iron).
Q4. Fill in: A ______ diet contains all the nutrients in the right proportions. L1
Balanced. A balanced diet has carbs, proteins, fats, vitamins, minerals, water and fibre.
Q5. True/False: Since milk contains proteins, fats, and calcium, a person can live on milk alone. L4
False. Milk lacks enough iron, vitamin C and dietary fibre. No single food is "complete" — variety is essential for balance.
🧩 Assertion – Reason
Assertion (A): Eating iodised salt prevents goitre.
Reason (R): Iodine is needed by the body for proper physical and mental activity.
A. Iodised salt supplies iodine, whose deficiency causes goitre — so R correctly explains A.
Assertion (A): Grandmother's diet of only rice and pickle is a balanced diet.
Reason (R): Rice contains all seven nutrients.
A false, R false — none of the four options fit perfectly; best choice is that BOTH are false. (Convention: if both are false, many CBSE papers still mark closest as per choices; the intended pedagogical takeaway — rice is mainly carbs, and rice+pickle is NOT a balanced diet.)
Assertion (A): Playing outside in the morning sunlight for 15 minutes is good for health.
Reason (R): Sunlight helps our skin make vitamin D, which keeps bones strong.
A. Morning sunlight helps our skin produce vitamin D, which keeps bones strong — Reason explains Assertion.
