Our bodies are incredible machines! They take the food we eat and transform it into energy that fuels everything we do, from running and jumping to even thinking and breathing. This energy comes from the nutrients in our food, like carbohydrates, proteins, and fats. These nutrients are broken down through digestion and then used to power our muscles and keep us moving. Think of food as the fuel that keeps your body's engine running!
