The food we take in is broken down into three energy nutrients in the course of digestion: proteins, fats and carbohydrates. It is through the bioenergetic conversion of these nutrients that our bodies are able to function and we are able to carry out physical activity.

They come to us almost entirely from foods that originate from plants, such as vegetable, fruits, and grain based foods, such as bread and pasta.
