A protein (or protide) is a blend of amino acids. Generally referred to as protein over 100 amino acids linked in a chain. There are animal protein and vegetable protein.
What are proteins?
Elements of construction and repair of the body, proteins play an important role.
They participate in the daily renewal of the skin, nails, hair and muscle tissue. They are also involved in the functioning of the body, especially in its defense against disease. They act by means of enzymes in numerous biological functions. Proteins are also essential for the growth of children and adolescents, as well as the formation of the fetus in pregnant women.
Protein: Where to find them?
Foods rich in animal protein are meat, fish, crustaceans, molluscs, eggs, milk and dairy products.
Foods rich in vegetable proteins are cereals, legumes (soybeans, lentils, beans, peas ...).
Vegetable proteins do not have the same nutritional qualities as animal proteins, because they lack one or more essential amino acids. Also, people on vegetarian diets, but especially those not eating or eggs, or dairy products, will compensate for any lack of certain amino acids.
