Key Concepts & Activities
B. Changing Cooking Practices
How Has Food Preparation Evolved?
| Time Period | Main Fuel/Tools | Common Methods | Characteristics |
|---|---|---|---|
| Traditional Era | Firewood, Chulha | Boiling, roasting | Slow cooking, hand-grinding, seasonal recipes |
| Mid-20th Century | Stove (Kerosene/LPG) | Pressure cookers | Faster cooking, some processed foods introduced |
| Modern Era | Induction, Microwave | Baking, reheating | Fast, convenience-based, ready-to-eat meals |
Activity 3: Interview elderly family/community members about traditional vs. modern cooking methods to understand cultural changes, nutrition, and sustainability.
C. Components of Food & Their Functions
A balanced diet supplies a mix of essential nutrients. Each nutrient plays a unique role:
| Nutrient | Major Functions | Main Sources | Deficiency Disease |
|---|---|---|---|
| Carbohydrates | Provide energy | Rice, wheat, potatoes, sugar | Weakness, fatigue |
| Proteins | Build and repair body tissues | Pulses, meat, eggs, milk, nuts | Kwashiorkor, weak muscles |
| Fats | Store energy, insulate & protect organs | Ghee, oil, butter, nuts, fish | Weakness, dry skin |
| Vitamins | Regulate body processes, prevent diseases | Fruits, vegetables, milk, eggs, liver | Night blindness (A), Scurvy (C), Rickets (D) |
| Minerals | Bones, teeth, blood, body functions | Salt, spinach, banana, milk, fish | Goitre (Iodine), Anaemia (Iron) |
D. Simple Nutrient Tests
| Component | Test Name | Sample Method | Expected Result |
|---|---|---|---|
| Starch | Iodine Test | Drop iodine on food | Turns blue-black |
| Protein | Biuret Test* | Add biuret solution | Turns violet/lilac |
| Fat | Paper/Blot Test | Rub on paper | Translucent, greasy spot |
Note: Biuret test involves chemicals and should only be conducted by teachers.
E. Balanced Diet
A balanced diet includes all nutrients in the right amounts suitable for age and activity. Example below shows a typical balanced day for a school child:
| Meal | Carbohydrates | Proteins | Fats | Vitamins/Minerals | Example |
|---|---|---|---|---|---|
| Breakfast | Wheat bread | Boiled egg | Butter | Fruit (vitamin C) | Paratha, egg, orange |
| Lunch | Rice/roti | Lentils | Ghee | Salad, curd | Dal, rice, salad |
| Snack | Poha | Chana | Peanuts | Raw veggies | Poha with sprouted chana and carrot |
| Dinner | Roti/Rice | Paneer | Oil | Cooked vegetables | Roti, paneer curry, bhindi |
Warning: Junk foods are high in fat/sugar and low in essential nutrients. They can cause obesity, dental problems, and nutrient deficiencies.
F. Millets as Nutritious Cereals
Millets like jowar, bajra, and ragi are ancient grains packed with nutrients. They are drought-resistant and healthy alternatives to rice and wheat.
| Millet | Key Nutrients | Health Benefits | Regions |
|---|---|---|---|
| Ragi | Calcium, Iron, Protein | Supports strong bones and blood health | Karnataka, Tamil Nadu |
| Bajra | Fiber, Magnesium, Iron | Good for heart and digestion | Rajasthan, Gujarat |
| Jowar | Protein, Fiber, Minerals | Easy digestion, energy | Maharashtra, Madhya Pradesh |
Students are encouraged to try millet-based foods and understand their nutritional benefits.
G. Food Miles
Food miles refer to the distance food travels from where it is grown to your plate. The longer the distance, the more energy is used in transport, causing pollution and sometimes loss of freshness.
Farm to Plate Journey:
- Farm → Transport (truck/train/ship) → Market → Store → Your Plate
Eating local foods means shorter food miles, supports local farmers, and provides fresher food.
Activity: Trace the journey of a common food item you eat and discuss the food miles involved.
Assessment
Formative Assessment
- Observe participation during activities and discussion sessions.
- Check students’ food diaries and survey reports.
- Conduct quick quizzes on nutrients and nutrient tests.
Summative Assessment
- Create a poster or display on what constitutes a balanced diet for children.
- Write a letter to the school principal advocating for healthier food options in the school canteen.
- Answer comprehension questions related to deficiency diseases and nutrition.
Extended Learning
- Prepare personalized diet charts and conduct family food habit interviews.
- Research and report on wild/local food varieties available in your region.
Frequently Asked Questions
- Why is eating a variety of foods important?
- To ensure all nutrients are obtained and to keep the body healthy.
- How do junk foods affect our health?
- They are high in fats and sugar but low in essential nutrients, leading to obesity and health problems.
- What are food miles, and why should we reduce them?
- Food miles are the distance food travels from farm to plate. Reducing them supports local farmers and lessens pollution.
- Are traditional foods healthier than modern packaged foods?
- Often yes, traditional foods are fresh, less processed, and nutritionally richer.
