Proteins, fats, carbohydrates, vitamins and minerals are necessary for the proper functioning of the organism.
Proteins bring amino acids essential to creating and renewing every tissue in our body.
In addition, proteins help chemical reactions in the organism.
Common sources of proteins are meats, fishes, eggs or milk.
Proteins are characterized by their high content in essential amino acids and their digestibility. Animal proteins are richer in essential amino acids than vegetable proteins and are generally more digestible.
Fats (or lipids)highly energetic, are essential for proper functioning of cells and of the organism. they play a role in the production of hormones and in the absorption of fat-soluble vitamins.
One can distinguish saturated fats (vital in very small quantities) and unsaturated fats (mono- or poly-unsaturated), beneficial for the cardiovascular system.
Depending their level of saturation, fats serve different objectives in the organism.
Carbohydrates are the main energy source of the organism. They contain simple or quick-burning sugars such as glucose or fructose and the complex or slow-burning sugars such as starch or dietary fibers.
Carbohydrates are the only source of energy for the brain. The starch is necessary to the diet. It is recommended to consume some every meal.
Dietary fibers keep your digestive system healthy and improve intestinal transit.
Vitamins, minerals and trace elements must be obtained through the diet because the organism can’t produce them otherwise. Some vitamins are fat-soluble (A, D, E, K) and others are soluble in the water contained by the food (B vitamins and vitamin C). Minerals are involved at all levels of the metabolic process.
A balanced and varied diet is essential to provide the organism with all indispensable vitamins.
Some vitamins are antioxidant and allow to neutralize the free-radicals and delay the muscle fatigue.
