What is ...?
Nutrients: these are substances that represent the “building blocks” of food, and which we use after digesting the food we eat.
Slow sugars or carbohydrates: these are the best form of energy, because it is released little by little. This energy can last an entire afternoon (or morning), and is used up when you run, play, think...; when you make an effort to do things.
Fats or lipids: these are the nutrients that store most energy. Our body uses them to construct certain important molecules (hormones, cholesterol...), and is reluctant to lose them. Fats that are not used during exercise are stored as fatty tissue.
Proteins: these are the elements we need for growth and repair. They help form our muscles, skin, hair, internal defenses and many other body structures.
Vitamin A: very good for the eyesight, skin, growth and reproduction.
Group B vitamins: necessary for growth and skin. These vitamins make it possible to fully use carbohydrates and proteins.
