1Can you think of at least five ingredients or food items that match each of the tastes listed below? Write them down in the spaces provided.
Tastes: Sweet | Sour | Salty | Pungent | Bitter | AstringentShow solution
| Taste | Sweet | Sour | Salty | Pungent | Bitter | Astringent |
|---|---|---|---|---|---|---|
| Example | Jaggery | Tamarind | Salt | Green chilli | Neem | Raw mango |

| 4 | Banana | Raw tomato | Salted peanuts | Black pepper | Coffee | Spinach |
| 5 | Dates | Kokum | Salted butter | Onion | Neem leaves | Arjuna bark tea |
Key concept: According to Ayurveda, these six tastes are called 'Shad Rasa'. Eating food that contains all six tastes in a balanced way is considered good for health.
Discuss — Food Items with Three or More Tastes
1Discuss in small groups and identify the food items having at least three different tastes.Show solution
Examples of food items with three or more tastes:
1. Tamarind chutney — Sour (tamarind) + Sweet (jaggery/sugar) + Pungent (ginger/chilli) + Salty (salt) → four tastes.
2. Sambhar — Sour (tamarind) + Pungent (pepper/chilli) + Bitter (fenugreek seeds) + Salty (salt) → four tastes.
3. Amla (Indian gooseberry) — Sour + Bitter + Astringent + slightly Sweet → four tastes.
4. Rasam — Sour + Pungent + Salty + Bitter → four tastes.
5. Chyawanprash — Sweet + Sour + Pungent + Bitter + Astringent → five tastes.
Conclusion: Many traditional Indian foods and condiments naturally combine multiple tastes, which is why they are considered healthy according to Ayurveda.
Find Out — Millet-Based Food
1Find out more about a millet-based food prepared at your home.Show solution
Name of the millet-based food: Bajra Roti (Pearl millet flatbread)
Millet used: Bajra (Pearl millet)
How it is prepared:
1. Bajra flour is kneaded with water to make a soft dough.
2. Small balls of dough are flattened by hand into round rotis.
3. They are cooked on a hot tawa (griddle) on both sides until brown spots appear.
4. A little ghee or butter is applied on top.
When it is eaten: Mostly in winters, as bajra generates heat in the body.
Nutrients it provides: Bajra is rich in iron, calcium, fibre, and protein — making it a 'super food'.
*(Students should replace the above with the actual millet food prepared in their own home.)*
Write — Why We Need Different Kinds of Food
1Why do we need to eat different kinds of food items?Show solution
Answer:
We need to eat different kinds of food items because:
1. Different nutrients: No single food provides all the nutrients our body needs. Different foods give us carbohydrates, proteins, fats, vitamins, and minerals.
2. Energy: Energy-giving foods (rice, wheat, potatoes) give us strength to work and play.
3. Growth and repair: Body-building foods (milk, eggs, pulses, meat) help our body grow and repair itself.
4. Protection from diseases: Protective foods (fruits and vegetables) contain vitamins and minerals that keep us healthy and protect us from illnesses.
5. Balanced diet: Eating a variety of colourful foods ensures we get a balanced diet, which keeps us active and happy.
Conclusion: Eating different kinds of food items ensures our body gets all the nutrients it needs to stay healthy, grow properly, and fight diseases.
Write — Junk Food
1Can you name a few more junk food items?Show solution
More examples of junk food:
1. French fries
2. Instant noodles (Maggi-type)
3. Candy and toffees
4. Ice cream (packaged, with artificial flavours)
5. Fried namkeen / bhujia
6. Packaged biscuits with cream filling
7. Chocolate bars
8. Canned juices with added sugar
9. Pani puri made with unhygienic water
10. Packaged wafers / nachos
2Why do you think we should avoid eating junk food?Show solution
Reasons to avoid junk food:
1. Lack of nutrients: Junk food does not provide the vitamins, minerals, and proteins our body needs.
2. Weight gain: High amounts of oil, sugar, and fat in junk food can lead to unhealthy weight gain.
3. Tooth decay: Sugary junk foods cause cavities and damage teeth.
4. Digestive problems: Junk food is low in fibre, which can cause constipation and other digestive issues.
5. Low energy: Despite being high in calories, junk food does not give sustained energy and can make us feel tired.
6. Risk of diseases: Regular consumption can lead to diseases like diabetes, high blood pressure, and heart problems later in life.
7. Replaces healthy food: When we eat junk food, we tend to eat less of the healthy food our body actually needs.
Conclusion: We should avoid junk food and prefer fresh, home-cooked meals to stay healthy and active.
3List the junk food items that you will avoid.Show solution
I will try to avoid the following junk food items:
1. Soft drinks (cola, soda)
2. Chips and packaged wafers
3. Burgers and pizza from fast-food outlets
4. Instant noodles
5. Candy and toffees
6. French fries
7. Packaged cream biscuits
8. Fried namkeen
My plan: Instead of these, I will eat fruits, home-cooked food, nuts, and drink water or fresh fruit juice.
*(Students should write their own personal list based on what they actually consume.)*
Activity 1 — Make a Food Diary
1Create a food diary of your daily routine for a week. Write down what you eat in a day for breakfast, lunch and dinner. Encircle the food items that are healthy and put an 'X' mark for items which are not healthy. Identify the food groups missing in your daily routine.Show solution

- Put X on: Chips, soft drinks, packaged snacks (if any were eaten).
Step 3 — Missing food groups:
- Check if fruits are eaten every day.
- Check if milk/dairy is included.
- Check if enough vegetables of different colours are on the plate.
- Discuss with parents how to include missing items.
*(Students must fill in their own actual food diary for the week.)*
Write — Methods of Cooking
1Identify different methods used to cook the food items given in the list below: Idli, Kheer, Dosa, Samosa, Rice, Peda, Sambhar, Gulab Jamun, Papad. One example is given: Steaming — Idiyappam.Show solution
Concept: Different foods are cooked using different methods depending on the ingredients and the desired result.
Completed Table:
| Method of Cooking | Food Items |
|---|---|
| Steaming | Idli, Idiyappam, Dhokla |
| Boiling | Rice, Kheer, Sambhar |
| Frying | Dosa (shallow frying), Samosa (deep frying), Gulab Jamun (deep frying), Papad (deep frying) |
| Roasting | Papad (can also be roasted), Peanuts |
| Baking | Bread, Cake, Biscuits |
| Grilling | Paneer tikka, Corn |
| No cooking (raw) | Fruit chaat, Vegetable salad |
Note on specific items:
- Idli → Steaming
- Kheer → Boiling
- Dosa → Shallow frying on a tawa
- Samosa → Deep frying
- Rice → Boiling
- Peda → Made by reducing milk on heat (boiling/simmering)
- Sambhar → Boiling
- Gulab Jamun → Deep frying, then soaked in sugar syrup
- Papad → Roasting or frying
Conclusion: The same food can sometimes be cooked by more than one method (e.g., papad can be roasted or fried). Steaming and boiling are generally healthier methods than deep frying.
Discuss — Cooking at Home
1Do you help in cooking at home?Show solution
Yes, I sometimes help in cooking at home. I help my mother/father by:
- Washing vegetables and fruits.
- Setting the table before meals.
- Kneading dough for rotis.
- Stirring ingredients while they are being cooked (with adult supervision).
- Making simple items like salad or fruit chaat on my own.
Helping in the kitchen teaches me about different foods, cooking methods, and the importance of cleanliness while preparing food.
2Do you think all family members should know how to cook? Why?Show solution
Reasons:
1. Self-reliance: If one person in the family is unwell or away, others can prepare food for themselves.
2. Healthy eating: When we know how to cook, we can prepare fresh, healthy food at home instead of depending on junk or packaged food.
3. Sharing responsibility: Cooking is a household responsibility that should be shared by all members, not just one person (usually the mother). This is fair and respectful.
4. Life skill: Cooking is an important life skill that everyone needs, especially when they grow up and live independently.
5. Bonding: Cooking together as a family is a fun activity that brings family members closer.
Conclusion: Cooking is not just one person's job. All family members — children, fathers, mothers, and grandparents — should know how to cook basic meals.
Let Us Reflect
1Hands-on activity — Food Collage: Cut out pictures of food items and create a collage with three sections: energy-giving foods, body-building foods, and protective foods.Show solution
Concept — Three Food Groups:
Section 1 — Energy-giving foods (carbohydrates and fats):
- Rice, wheat, bread, roti, potato, maize, sugar, jaggery, ghee, butter, oil.
Section 2 — Body-building foods (proteins):
- Milk, curd, paneer, cheese, eggs, fish, chicken, dal (lentils), rajma, chana, soybean, nuts.
Section 3 — Protective foods (vitamins and minerals):
- All fruits: apple, banana, orange, mango, guava, papaya.
- All vegetables: spinach, carrot, tomato, brinjal, peas, capsicum.
How to make the collage:
1. Take a blank sheet of paper and divide it into three sections with a pencil.
2. Label each section: 'Energy-giving Foods', 'Body-building Foods', 'Protective Foods'.
3. Cut pictures of food items from old magazines or newspapers.
4. Paste each picture in the correct section.
5. Decorate the collage with colours.
Conclusion: A balanced plate should have all three groups, with protective foods (fruits and vegetables) taking up the most space.
2aCheck the label: At home, pick up any one packaged food item from your kitchen. Check the label and note down the expiry date, and also two main ingredients.Show solution
Sample Answer (based on the honey jar shown):
- Product: Honey
- Net weight: 400 grams
- Packed on: 08.03.2025
- Best before (Expiry date): 07.03.2026
- Two main ingredients: (1) Pure natural honey, (2) No added sugar
For students' own activity:
Pick any packaged item from your kitchen (e.g., biscuits, jam, juice, dal packet) and note:
1. Name of the product: ___________
2. Expiry / Best before date: ___________
3. Main ingredient 1: ___________
4. Main ingredient 2: ___________
2bWhy is it important to check labels before buying or eating packaged food items?Show solution
It is important to check labels before buying or eating packaged food items because:
1. Expiry date: Labels tell us the 'Best Before' or 'Expiry' date. Eating food after its expiry date can make us very sick.
2. Ingredients: Labels list all the ingredients used. This helps us know if the food contains anything we are allergic to or anything unhealthy (like too much sugar, salt, or artificial colours).
3. Nutritional information: Labels show the amount of calories, fat, protein, sugar, etc., helping us make healthier choices.
4. Quantity: Labels mention the net weight or volume, so we know how much we are buying.
5. Manufacturer details: Labels give the name and address of the manufacturer, so we can trust the product and report problems if needed.
6. Storage instructions: Labels tell us how to store the food properly (e.g., 'Refrigerate after opening').
Conclusion: Always check the label before buying or eating any packaged food. It helps us stay safe and make healthy choices.
