1. Biological Importance of Food Growth, Energy, and Repair

2. Definition of Food • Food is any substance consumed to provide the nutrients essential for life, growth, and health. • Food is essential for energy, supporting bodily functions, growth, and tissue repair.

3. Function of Food • Growth: Food provides the building blocks (proteins, vitamins, minerals) needed for the development and maintenance of body tissues. • Energy: Carbohydrates, fats, and proteins from food are broken down to provide energy for bodily functions and activities. • Repair: Nutrients help repair tissues, regenerate cells, and maintain bodily structures.

4. Importance of Food • Growth: Proper nutrition is essential for physical development and cellular growth. • Energy: Food provides the energy needed for metabolism, physical activity, and mental functions. • Repair: Nutrients aid in tissue repair and recovery from injury or daily wear and tear.

5. Biological Food • Biological food refers to natural sources of food that provide essential nutrients. • These foods are often unprocessed or minimally processed, coming from plant or animal sources. • Examples include fruits, vegetables, whole grains, meats, and dairy products.
