Final answer:
Our bodies need fuel in the form of food, which is broken down into nutrients that our body can use. Carbohydrates, fats, and proteins are the main sources of fuel for our bodies.
Step-by-step explanation:
Our bodies need fuel in order to carry out essential functions and provide energy for daily activities. This fuel comes in the form of food, which is broken down into nutrients that our body can use. The main sources of fuel for our bodies are carbohydrates, fats, and proteins.
Carbohydrates, such as bread, pasta, and fruits, are a quick source of energy as they are easily broken down into glucose. Fats, found in foods like oils and butter, provide a more sustained source of energy. Proteins, found in foods like meat, eggs, and beans, serve as building blocks for our muscles and tissues, but can also be used as an energy source when needed.
In summary, our bodies need fuel (food) to provide energy for various bodily functions. This fuel comes from carbohydrates, fats, and proteins found in the foods we eat.
