About the chapter

Our food gives us energy and keeps us healthy. This chapter tells us about the nutrients in food and a balanced diet. We learn about deficiency diseases. We also learn how to cook food without losing its nutrients.

Key points

  • Carbohydrates give energy. Proteins help in growth and repair of the body.
  • Vitamins and minerals protect us from diseases.
  • Fibres keep the stomach clean. Water removes wastes from the body.
