Food — Sources, Nutrients and Eating Habits | CTET EVS P1

Sources of Food — Plant and Animal

NCERT EVS classifies food into plant sources and animal sources, and within plants further by the part of the plant we eat. The Class IV chapter 'From a Bone to a Stone' and Class V 'Seeds and Seeds' and 'Mangoes Round the Year' all develop this theme.

Plant sources grouped by edible part:

• Roots: carrot, beetroot, radish (mooli), sweet potato, tapioca, sugar-beet, turnip.
• Stems: potato (an underground stem-tuber), ginger (rhizome), turmeric (rhizome), sugarcane.
• Leaves: spinach (palak), fenugreek (methi), coriander, mint, cabbage, mustard greens (sarson).
• Flowers: cauliflower, broccoli, banana flower (kele ka phool), drumstick flower.
• Fruits: mango, banana, apple, tomato, brinjal, pumpkin, okra (lady-finger), cucumber.
• Seeds: rice, wheat, maize, jowar, bajra, ragi (cereals); chana, moong, masoor, urad, rajma (pulses); peanut, almond, walnut (nuts); mustard, sunflower, sesame (oil seeds).

This is a CTET hot-spot — students confuse roots with underground stems. The classic test item asks which group is genuinely a 'group of roots'; the correct answer always lists carrot, beetroot, radish (or similar). Potato, ginger and turmeric, though dug from the ground, are stems.

Animal sources:

• Milk and milk products — cow, buffalo, goat, yak.
• Meat — fish, chicken, mutton, beef (depending on region and community).
• Eggs — hen, duck, quail.
• Honey — wild and apiary bees.

NCERT carefully treats food choice as cultural, religious and personal. The textbook never labels any group's food 'better' or 'worse'. Children share what their families eat without judgement, and the teacher uses this diversity to build inclusion. Class V's 'Tasting Time' chapter explicitly traces how foods like potato, tomato, chilli and tea travelled to India from other continents — making food history a global story.

Major Nutrients and Their Functions

Primary EVS introduces five main nutrient groups in simple, age-appropriate language. Class V's 'No Place for Us?' and the Class IV health chapters lay this foundation, which is then built upon in middle-school science.

• Carbohydrates — energy-givers. Sources: rice, wheat, bajra, jowar, ragi, maize, potato, sugar, jaggery, banana. Children are told that bread, rice and chapati provide the 'fuel' for running, playing and thinking.
• Fats — energy-storage and warmth. Sources: ghee, butter, oils (mustard, groundnut, coconut, sesame, sunflower), nuts, seeds, milk cream. NCERT does not demonise fats; they are necessary, especially for growing children.
• Proteins — body-builders. Sources: pulses (dal), beans, soya, paneer, milk, eggs, fish, meat, nuts. Vegetarian protein combinations (dal-chawal, idli-sambar, khichdi) are highlighted as nutritionally complete.
• Vitamins and minerals — protectors. Sources: fruits and vegetables of every colour. Children learn that iron (in spinach, jaggery, amla, drumstick leaves) prevents anaemia; calcium (in milk, curd, ragi, sesame) builds strong bones; vitamin C (in amla, lemon, guava, orange) prevents bleeding gums; vitamin A (in carrot, papaya, mango, dark greens) protects eyesight; vitamin D (from sunlight and fortified milk) helps calcium absorption.
• Water — essential for life. Two-thirds of our body is water; we lose it constantly through urine, sweat and breath.

A CTET-tested concept is the iron-rich food group — amla, spinach (palak) and jaggery (gur) are the classic three. Children with iron-deficiency anaemia are pale, tire easily and study poorly; mid-day meal menus are designed with this in mind.

The teacher links nutrient knowledge to local affordability. Children may not have access to apples and almonds, but ragi, amla, drumstick leaves, sesame, jaggery and seasonal greens are inexpensive and superior. The pedagogical goal is not consumerism but informed choice within the family budget.

Balanced Diet for Children

A balanced diet provides all nutrients in correct proportions for the child's age, activity and growth. NCERT EVS uses the ICMR (Indian Council of Medical Research) food-group framework rather than imported food pyramids — Indian foods, Indian portions.

For a primary-school child (6–10 years), a balanced day's plate looks like this:

• Largest portion — cereals and millets: rice, wheat, bajra, jowar, ragi, maize. These provide the bulk of daily energy.
• Generous portion — pulses, beans and animal proteins: at least one serving of dal/chana/rajma/egg/fish/paneer at each meal.
• Plenty — fruits and vegetables: two or three servings, mixing greens, yellows, oranges and reds.
• Moderate — milk and milk products: 300–500 ml a day or equivalent.
• Small — fats, oils, sweets: for cooking and occasional treats, not the staple.

This is a frequently tested CTET point. When asked which food group should form the largest portion, the answer is cereals and millets, not fats and not sweets.

The textbook insists on variety, seasonality and locality:

• Variety — different foods cover different nutrient gaps. No single food is complete.
• Seasonality — summer needs more water-rich foods (cucumber, watermelon, buttermilk); winter needs warming foods (jaggery, sesame, dry fruits).
• Locality — Kerala's rice-fish-coconut diet, Punjab's wheat-dairy diet, Rajasthan's bajra-buttermilk diet are all balanced in their own ecology.

The chapter also confronts junk food in age-appropriate language. Packaged chips, biscuits, colas and sweets are 'sometimes foods' — high in salt, sugar, fat and chemicals but low in body-building nutrients. The teacher does not shame children for eating them but builds awareness through label-reading activities and 'rainbow-plate' games.

Special concern is paid to adolescent girls entering puberty, who need extra iron and calcium, and to tribal and remote-area children whose diets depend on what the season and forest provide.

Cooking — Methods and Importance

Cooking, in NCERT EVS, is not a girl's chore but a science, craft and family activity that every child should observe and learn. The Class V chapter 'Khana Apna Apna' turns the kitchen into a laboratory.

Cooking methods commonly studied:

• Boiling — water at 100°C; for rice, dal, vegetables, eggs.
• Steaming — for idli, momo, dhokla; retains nutrients well.
• Roasting — over open flame; for chapati, bhutta (corn), papad.
• Frying — shallow (paratha, dosa) or deep (puri, samosa); uses more oil.
• Baking — dry heat in oven or tandoor; for bread, naan, cake.
• Grinding and pounding — for masalas, chutneys; the mortar-pestle and grinder (sil-batta, chakki).
• Fermentation — bacteria and yeast at work; for curd, idli batter, dhokla, dosa, bhatura.

Why does cooking matter?

• Safety: heat kills harmful germs; raw meat, fish and many vegetables are unsafe.
• Digestibility: cooking breaks down starches and fibres so our body can absorb nutrients.
• Taste and culture: spice combinations and techniques carry the identity of a region — Bengal's mustard fish, Goa's coconut prawn curry, Kashmir's wazwan, Maharashtra's puran-poli.
• Family bonding: meals cooked and eaten together strengthen relationships.

An important CTET-tested concept matches regional cooking media to states: Kerala uses coconut oil and seafood; Bengal uses mustard oil; Kashmir favours dried fruits, saffron and mutton; Punjab uses ghee and dairy; Goa uses coconut, palm vinegar and seafood; Hong Kong is famous for cooked snake. The matching-column item in CTET 2019 tests exactly this geographical-cuisine pairing.

Pedagogically, the teacher invites parents and grandparents to demonstrate a family dish — turning the classroom into a multicultural kitchen. Boys are actively included; the textbook deliberately challenges the stereotype that cooking is women's work.

Food Habits Across Cultures

India's food map is astonishingly diverse, and NCERT EVS uses it to teach cultural geography. Class V's 'Tasting Time' traces the journeys of foods across continents and centuries.

Foods that came to India from elsewhere:

• From South America (via Portuguese traders, 16th century onwards): chilli (mirchi), potato, tomato, maize, pineapple, sweet potato, cashew, papaya, guava, tapioca, peanut. The textbook explicitly notes that Indian food cannot be imagined without chillies, yet chillies are a recent import.
• From China and East Asia: tea, noodles.
• From the Middle East and Central Asia (via Mughal and earlier trade): biryani, samosa, kebab, naan, pulao.
• From Africa: coffee, watermelon, okra (lady-finger).
• From Europe (post-British): cabbage, cauliflower, beetroot in modern form, bread loaf.

This is a CTET-tested item: 'Chillies were brought to our country by traders coming from…' Answer: South America.

Within India, food varies by region:

• South: rice, sambar, rasam, idli, dosa, coconut, curry leaves, tamarind.
• East: rice, fish (mustard or panch-phoron), pitha, mishti doi.
• North-East: bamboo shoot, rice beer, smoked pork, fermented soybean (axone in Nagaland, akhuni).
• North: wheat (chapati, paratha, naan), dairy (lassi, butter), dal-makhani, chole-bhature.
• West: Gujarat (dhokla, thepla, kadhi); Rajasthan (dal-baati, churma, ker-sangri); Maharashtra (vada-pav, puran-poli); Goa (fish curry, vindaloo).

Some foods are clearly identified with people: Kerala loves boiled tapioca with curry; Kashmir cooks fish in mustard oil; Goa cooks sea-fish in coconut oil. Tribal food traditions are also acknowledged with respect — including hunted forest foods and indigenous grains.

The teacher's goal is to celebrate this diversity without ranking. The 'food-map' bulletin board, where each child pins a recipe from home, is a powerful EVS activity.

Food Storage and Preservation

Why preserve food? Seasons and harvests are uneven; preservation lets us eat mangoes in winter, store grain through a poor monsoon, and avoid wastage. NCERT EVS covers traditional and modern methods together.

Traditional preservation methods:

• Drying: turmeric, chillies, papads, badis, dried fish, raisins, dates, sun-dried mangoes (aamchur).
• Salting: pickles (achaar), salted fish, salted lemon.
• Sugaring: jams, murabbas, gulkand (rose preserve).
• Souring: vinegar-based pickles; tamarind concentrate.
• Smoking: fish, meat in north-eastern kitchens.
• Fermenting: curd, pickles, idli batter; controlled microbes that prevent harmful ones.
• Granaries: mud bins (kothi, mortha, bukhari) lined with neem leaves; raised wooden granaries on stilts in the North-East.

Modern preservation methods:

• Refrigeration — cold slows microbial growth.
• Freezing — for meat, fish, peas; can last months.
• Canning and bottling — vacuum-sealed in glass or tin.
• Vacuum packaging — removes oxygen.
• Pasteurisation — heat-treated milk; kills germs without spoiling taste.
• Chemical preservatives — sodium benzoate, citric acid; used in jams and sauces.

The textbook handles preservation as a knowledge of grandmothers — many traditional methods are scientifically sound and chemical-free. Children interview elders about how they stored grain, pickled lemons or made papad in their own childhood, recording techniques and recipes for the class archive.

The chapter also discusses food spoilage: warm-wet conditions encourage bacteria, mould and insects. Symptoms of spoilage — smell, slime, mould patches, sour taste — are taught so children develop food-safety judgement. Eating spoiled food causes vomiting, diarrhoea and dehydration, especially dangerous in small children.

An EVS classroom activity: place a chapati in three jars — open, closed dry, closed wet — and observe over a week. Children see for themselves how moisture and air invite spoilage.

Hunger, Malnutrition and Mid-Day Meal

NCERT EVS confronts the unevenness of food access in India with honesty. Children read stories of hunger and learn about government programmes that fight it.

Key concepts:

• Hunger — not enough food to satisfy basic energy needs. Visible in stunted growth, low weight, fatigue.
• Malnutrition — wrong food, even if quantity is enough. Includes under-nutrition (deficiency: anaemia from low iron, goitre from low iodine, rickets from low vitamin D) and over-nutrition (excess: obesity, diabetes, heart disease — increasingly seen in urban children eating processed food).
• Food security — every household having reliable access to enough nutritious food, every day of the year. India has a Food Security Act (2013).

Government schemes the EVS book introduces:

• Mid-Day Meal Scheme (now PM POSHAN, since 2021) — every government school child gets a hot, cooked meal at school. Started in Tamil Nadu (1962), nationalised after the Supreme Court's 2001 order. Goals: nutrition, school enrolment and retention, and the social mixing that comes from eating together.
• Public Distribution System (PDS) — subsidised rice, wheat, dal, oil, salt, sugar through ration shops.
• Integrated Child Development Services (ICDS) — anganwadi centres provide nutrition, immunisation and pre-school for under-six children, pregnant and nursing mothers.
• National Food Security Act — legal right to subsidised foodgrains for two-thirds of India's population.

The mid-day meal also has a pedagogical role. Eating together breaks caste, class and religious barriers. Earlier reports of upper-caste teachers refusing to share meals with Dalit cooks led to strict rules requiring teachers to eat with children. CTET often probes the teacher's stance — the right pedagogical answer always involves the teacher eating with the children, never sitting apart.

Teachers are also expected to spot signs of under-nutrition — chronic absenteeism, sleepiness in class, pale skin, loose clothing — and to act with sensitivity. The food chapter is therefore not only about biology; it is about citizenship and care.

Teaching Food Concepts in EVS

Food is the most teachable theme in EVS because every child arrives with rich knowledge from home. The challenge is not to introduce food but to build outward from what children already know — through observation, conversation, classification and small experiments.

Constructivist food activities:

• Tiffin show-and-tell: each child describes what they ate today and identifies plant/animal sources and a nutrient or two. Builds vocabulary without textbooks.
• Food-source classification: children sort cards or pictures into root/stem/leaf/flower/fruit/seed; this is where misconceptions (potato = root) surface naturally.
• Sprouting experiment: rajma, moong, chana in cotton wool; children measure and draw daily for a week.
• Spice walk: a tray of haldi, jeera, dhania, hing, kali mirch, laung — smell, identify, share home uses.
• Food map of India: a wall map where children pin a regional dish (with help from family).
• Label-reading: packaged-food labels; identify sugar, salt, fat content.
• Cooking demo (no-flame): simple uncooked recipes like fruit chaat, bhel-puri, sprout salad, lemonade — taught in school.
• Recipe collection: grandmother-grandfather interviews about a dish from their childhood; transcribed and bound as a class cookbook.

Pedagogical principles to honour:

• Never rank foods. No food a child brings is 'inferior' or 'smelly'. Comments shaming a child's tiffin damage self-esteem and reinforce class/caste hierarchies.
• Honour diverse diets. Vegetarian, non-vegetarian, religious restrictions, allergies — all welcomed without judgement.
• Connect to body, family and culture. Food is biology + economics + history + religion + identity in one theme.
• Use multi-sensory tools. Smell, taste, touch and sight all teach more than text alone.
• Bring real grains, real spices, real fruits into the classroom — picture-only teaching is a CTET-flagged weakness.

The teacher who treats the lunch break as part of the EVS lesson — sitting with children, asking 'what's in your tiffin today?', sharing across plates — does more for the food chapter than any textbook can.
