FAQs on Worksheet: Food: Our Basic Need - 1

1. What are the different types of food and why do we need them in our diet?
Ans. Food is divided into five main groups: proteins, carbohydrates, fats, vitamins, and minerals-each serving different purposes in the body. Proteins build muscles, carbohydrates provide energy, fats store energy, vitamins boost immunity, and minerals strengthen bones and teeth. A balanced diet includes all these nutrients to keep the body healthy and functioning properly.
2. How can I identify which foods are sources of protein for Class 4 science?
Ans. Protein-rich foods include eggs, meat, fish, beans, lentils, milk, and nuts. These foods help build and repair muscles and tissues in the body. Students can recognise protein sources by remembering that they're often animal products or plant-based legumes, making them essential components of a nutritious diet for growth and development.
3. What's the difference between carbohydrates and fats as energy-giving foods?
Ans. Carbohydrates provide quick energy and are found in rice, bread, and potatoes, while fats store long-lasting energy and come from oils, butter, and nuts. Both are energy-giving foods, but carbohydrates are the body's primary fuel source for daily activities, whereas fats provide concentrated energy reserves for extended physical exertion.
4. Why do growing children need more nutrients than adults according to CBSE science curriculum?
Ans. Growing children require additional nutrients because their bodies are developing rapidly-bones are strengthening, muscles are building, and organs are maturing. Adequate protein, calcium, and vitamins support this growth process. Children need more food proportionally than adults to fuel physical activity, brain development, and the continuous building of new body tissues during childhood.
5. How do vitamins and minerals protect our bodies from diseases and illness?
Ans. Vitamins and minerals boost the immune system by strengthening the body's defence against infections and diseases. Vitamin C from citrus fruits protects against colds, calcium from milk builds strong bones, and iron from spinach prevents anaemia. These protective nutrients work together to keep the body functioning optimally and resist common illnesses in everyday life.
