ATP : adenosine triphosphate, the substrate enabling cells to convert energy into muscular exercise.
Carbohydrates : nutrients that must represent 50 to 55% of the daily energy in a balanced diet. We distinguish foods rich in complex carbohydrates (starchy foods) from those rich in simple carbohydrates (sugar, fruit, sweets, etc.). In a balanced diet, foods rich in complex carbohydrates should form the larger part of the daily diet.
