Key idea
Food Across India
Food choices are shaped by locally grown crops and local traditions.

Punjab

Wheat and maize form the base of many traditional dishes.

Karnataka

Rice-based dishes are common, reflecting the region’s staple crop.

Manipur

Rice and bamboo shoots feature widely in everyday cooking.

Key idea
Changing Culinary Practices
Technology, transport, and communication have changed how India cooks.
Then

Cooking on a chulha (wood-fired stove), and grinding spices on a sil-batta (stone grinder).

Now

Gas stoves and electric grinders — faster, but a big shift from tradition.

Key idea
Energy-Giving Foods
Carbohydrates and fats together power everything the body does.

Carbohydrates

The primary energy source — cereals, potatoes, fruits like banana and mango, and sugar.

Fats

A source of stored energy — nuts, seeds, ghee, oils, and animal sources.

Key idea
Proteins: Body-Building Foods
Proteins help the body grow and repair itself — especially important while growing.

Plant sources

Pulses, beans, peas, and nuts.

Animal sources

Milk, paneer, egg, fish, and meat.

Key idea
Vitamins and Minerals
Small amounts, big protection — missing one shows up as a specific illness.

Vitamin A

Papaya, carrot, milk
Night blindness

Vitamin B1

Wholegrains, pulses
Beriberi

Vitamin C

Citrus fruits
Scurvy

Vitamin D

Sunlight, milk, egg
Rickets

Iodine

Iodised salt
Goitre

Iron

Leafy vegetables, jaggery
Anaemia

Key idea
Roughage and Water
Two things the body needs every day that aren’t nutrients at all.

Roughage

Found in leafy vegetables, fruits, and wholegrains. Gives no nutrients, but keeps digestion smooth.

Water

Helps absorb nutrients and removes waste through sweat and urine.

Key idea
Testing Food for Nutrients
Simple tests reveal what's really inside a food.

Starch test

Add iodine solution — turns blue-black.

Fat test

Rub on paper — leaves an oily, translucent patch.

Protein test

Add copper sulfate and caustic soda — turns violet.

Key idea
Balanced Diet vs Junk Food
Balanced diet

Has all essential nutrients, roughage, and water in the right amounts — the right mix depends on age, gender, and activity.

Junk food

High in sugar, fat, and calories, but low in protein, vitamins, and fibre. Frequent eating can cause health problems.

Key idea
Millets and Food Miles

Millets

Jowar, bajra, ragi, and sanwa — native Indian grains rich in vitamins, iron, and fibre.

Food miles

The distance food travels to reach us. Shorter distances cost less, pollute less, and stay fresher.
