Worksheet 2: Class 6 Science - Components of Food

Welcome! This worksheet will help you understand the different components of the food we eat and their importance for our body. Let's explore the world of nutrients and balanced diets!

What Are the Components of Food?

Our food contains several components that are essential for our body's growth and health. These are called **nutrients**. The main nutrients found in food are:

• Carbohydrates: These are the body's main source of energy. They are found in foods like rice, wheat, and potatoes.
• Proteins: Known as the "body-building food," proteins help in the growth and repair of our body tissues. Pulses, milk, eggs, and meat are rich in protein.
• Fats: Fats also provide energy, and they give us even more energy than carbohydrates. Butter, oil, and nuts are sources of fat.
• Vitamins: Vitamins help protect our body against diseases. We need them in small amounts. Different vitamins like A, C, D, and E are found in fruits, vegetables, and milk.
• Minerals: Minerals are also needed in small quantities for the proper functioning of our body. Examples include iron, calcium, and iodine.
• Water: Water helps our body absorb nutrients from food and gets rid of waste.
• Roughage (Dietary Fibre): This helps our body get rid of undigested food and is found in whole grains, fruits, and vegetables.

To stay healthy, we must eat a **balanced diet** that contains all these nutrients in the right amounts.
