Chapter Notes

Overview
This chapter explores the importance of food, its components, and how mindful eating leads to a healthy body. It explains why food diversity exists across India, how cooking practices have changed over time, and what nutrients our body needs. The one big idea a student must walk away with is that a balanced diet containing all essential nutrients, roughage, and water, along with mindful choices like eating local and avoiding junk food, is the key to good health.
Key Concepts (25)
Mindful Eating
Eating food that is wholesome, in moderate quantities, and appropriate for the season, time, and place.
e.g. Eating a warm bowl of dal-rice in winter and a light salad in summer is an example of mindful eating.
Carbohydrates
Nutrients that are one of the primary sources of energy in our diet.
e.g. Wheat, rice, potato, banana, and sugarcane are sources of carbohydrates.
Fats
A food component that provides stored energy and helps keep the body warm.
e.g. Ghee, butter, groundnuts, and almonds are sources of fats.
Proteins
Nutrients that help in growth and repair of the body; also called body-building foods.
e.g. Pulses, milk, paneer, eggs, fish, and soya bean are sources of proteins.
Vitamins
Protective nutrients that protect our body from diseases and keep us healthy, required in small amounts.
e.g. Vitamin C from lemons and oranges prevents scurvy.
Minerals
Inorganic nutrients that help perform various bodily functions and keep bones, teeth, and blood healthy.
e.g. Calcium from milk keeps bones strong; iron from green leafy vegetables prevents anaemia.
Balanced Diet
A diet that has all essential nutrients, roughage, and water in the right amount for proper growth and development of the body.
e.g. A meal with roti, dal, green vegetables, salad, and a glass of milk is a balanced diet.
Roughage (Dietary Fibres)
An essential component of food that does not provide nutrients but helps the body get rid of undigested food and ensures smooth passage of stools.
e.g. Green leafy vegetables, fresh fruits, whole grains, and nuts are good sources of roughage.
Deficiency Diseases
Diseases caused due to lack of one or more nutrients in the diet for a long time.
e.g. Scurvy (Vitamin C deficiency), goitre (iodine deficiency), anaemia (iron deficiency).
Junk Food
Foods that have high calories due to high sugar and fat content but very low amounts of proteins, minerals, vitamins, and dietary fibres.
e.g. Potato wafers, candy bars, and carbonated drinks are junk foods.
Millets (Nutri-cereals)
Small-sized, highly nutritious grains that are good sources of vitamins, minerals like iron and calcium, and dietary fibres; also called nutri-cereals.
e.g. Jowar, bajra, ragi, and sanwa (barnyard millet) are millets.
Food Miles
The entire distance travelled by a food item from the producer to the consumer.
e.g. Wheat grown in Punjab transported to a shop in Kerala has high food miles.
Iodised Salt
Common salt mixed with required quantities of salts of iodine to prevent goitre.
e.g. Most packaged salt in India is iodised salt.
Fortification
Adding more nutrients to food during processing to improve its nutritional quality.
e.g. Iodised salt and some baby foods are examples of fortified foods.
Culinary Practices
Methods and practices of cooking food.
e.g. Using a chulha (traditional stove) versus a modern gas stove.
Nutrients
Food components that provide energy, support growth, help repair and protect our body from diseases, and maintain various bodily functions.
e.g. Carbohydrates, proteins, fats, vitamins, and minerals are major nutrients.
Energy-giving Foods
Foods that provide energy for performing various activities; carbohydrates and fats are energy-giving foods.
e.g. Rice, chapati, butter, and ghee are energy-giving foods.
Body-building Foods
Protein-rich foods that help in growth and repair of the body.
e.g. Pulses, milk, eggs, and fish are body-building foods.
Protective Nutrients
Vitamins and minerals that protect our body from diseases and keep us healthy.
e.g. Vitamin A keeps eyes and skin healthy; calcium keeps bones and teeth healthy.
Scurvy
A deficiency disease caused by lack of Vitamin C, with symptoms including bleeding gums and slow healing of wounds.
e.g. Sailors on long voyages who did not eat citrus fruits often got scurvy.
Goitre
A deficiency disease caused by lack of iodine, with symptoms including swelling at the front of the neck.
e.g. People in Himalayan regions historically suffered from goitre due to iodine-deficient soil.
Rickets
A deficiency disease caused by lack of Vitamin D, with symptoms including soft and bent bones.
e.g. Children who do not get enough sunlight may develop rickets.
Anaemia
A deficiency disorder caused by lack of iron, with symptoms including weakness and shortness of breath.
e.g. Eating green leafy vegetables and beetroot helps prevent anaemia.
Beriberi
A deficiency disease caused by lack of Vitamin B1, with symptoms including swelling, tingling or burning sensation in feet and hands, and trouble in breathing.
e.g. Eating whole grains and legumes helps prevent beriberi.
Starch
A type of carbohydrate that can be detected using iodine solution, which turns blue-black in its presence.
e.g. Potato and bread contain starch.
How It Works
Test for Starch
  1. Take a small piece of the food item on a dish.
  2. Put 2–3 drops of diluted iodine solution on the food item using a dropper.
  3. Observe the colour change. If the food item turns blue-black, starch is present.
💡 Iodine turns blue-black only in the presence of starch. Sugar is a carbohydrate but does not turn blue-black with iodine because it is not starch.
Test for Fats
  1. Place the food item on a separate piece of paper.
  2. Wrap the paper around the food and press it. Be careful not to tear the paper.
  3. If the food item contains water, allow the paper to dry.
  4. Observe if an oily patch appears on the paper. Hold the paper against light; if light shines faintly through the patch, fat is present.
💡 An oily patch on paper indicates the presence of fat. Watery foods may leave a wet patch that dries, but an oily patch remains even after drying.
Test for Proteins
  1. Make a paste or powder of the food item using a pestle and mortar.
  2. Put about half a teaspoon of the food item in a clean test tube.
  3. Add 2–3 teaspoons of water and shake well.
  4. Add 2 drops of copper sulfate solution using a dropper.
  5. Add 10 drops of caustic soda solution using another dropper.
  6. Shake well and leave the test tube undisturbed for a few minutes.
  7. If the content turns violet, protein is present.
💡 The violet colour indicates the presence of proteins. These chemicals are harmful; do not touch or taste them. If spilled, wash immediately with water.
From Farm to Plate (Story of Chapati)
  1. Farmer grows wheat in the field.
  2. After harvest, threshing and winnowing of grains is done to separate the grain from the chaff.
  3. Grains are stored.
  4. Grains are ground into flour and packed.
  5. Flour is transported to retail shops.
  6. Food reaches our plate after cooking.
💡 The entire distance travelled by the food item from producer to consumer is called food miles. Reducing food miles helps cut costs, reduce pollution, support local farmers, and keep food fresh.
Exam Traps — Don't Make These Mistakes
⚠ Confusing 'carbohydrates' with 'starch'
✗ Sugar is a carbohydrate, so it should turn blue-black with iodine.
→ Iodine test detects only starch, a specific type of carbohydrate. Sugar is a carbohydrate but not a starch, so it does not turn blue-black.
✓ Sugar is a carbohydrate but not a starch; therefore, it does not give a blue-black colour with iodine solution.
⚠ Thinking all fats are unhealthy
✗ Fats are bad for health and should be completely avoided.
→ Fats are essential nutrients that provide stored energy and help keep the body warm. Only excessive or unhealthy fats (like in junk food) are harmful.
✓ Fats are essential energy-giving nutrients. They should be consumed in moderate amounts from healthy sources like nuts, seeds, and ghee.
⚠ Mixing up deficiency diseases and their causes
✗ Scurvy is caused by lack of Vitamin D.
→ Scurvy is caused by deficiency of Vitamin C, not Vitamin D. Vitamin D deficiency causes rickets.
✓ Scurvy is caused by a deficiency of Vitamin C. Its symptoms include bleeding gums and slow healing of wounds.
⚠ Believing roughage provides nutrients
✗ Roughage gives us energy and helps in growth.
→ Roughage (dietary fibres) does not provide any nutrients or energy. It helps in removing undigested food and ensuring smooth passage of stools.
✓ Roughage does not provide nutrients but is essential for proper digestion and preventing constipation.
⚠ Thinking all millets are the same as regular cereals
✗ Millets are just like rice and wheat, with no special benefits.
→ Millets are called nutri-cereals because they are rich in vitamins, minerals like iron and calcium, and dietary fibres, making them more nutritious than refined grains.
✓ Millets (jowar, bajra, ragi, sanwa) are nutri-cereals that provide vitamins, minerals, and dietary fibres, contributing significantly to a balanced diet.
