Macronutrients
Carbohydrates, proteins and fats are considered macronutrients. Our body uses these nutrients either to produce energy, or as "building material" for its various constituent parts, e.g. muscles, organs, bones, fat, cells, hormones, enzymes, etc. In addition to water and micronutrients, macronutrients are, in some cases, essential for survival and ensure the normal function of the entire organism.
Carbohydrates
Carbohydrates, unlike proteins and fats, are not essential for humans. Nevertheless, they play an essential role because they are important sources of energy for our body and give us the necessary power for our training and for our daily lives. Some examples of foods rich in carbohydrates are: bread, pasta, potatoes, rice, vegetables, fruit.
