In this section, we explore the nutritional health and well-being of preschool children aged 1-6 years. As children transition from infancy to preschool, their nutritional needs evolve while their activity levels increase. The section focuses on their specific dietary requirements, which include a balance of macronutrients such as carbohydrates, protein, and fat, along with essential vitamins and minerals. The section emphasizes the importance of developing healthy eating habits, which should be nurtured through family mealtimes, variety in diet, and exposure to different food textures, tastes, and colors. Additionally, the section provides insights into planning balanced meals and healthy snacks that cater to the energy needs of preschoolers, supported by guidelines from the Indian Council of Medical Research (ICMR) for recommended dietary allowances (RDAs). Ultimately, proper nutrition not only fuels their physical activity but also plays a crucial role in cognitive development and overall well-being.
