The cow's milk industry was historically born in a time of malnutrition and lack of food. Milk is a product rich in carbohydrates. The cow's milk has a fairly high nutritional value.
Due to the great influence of veganism in current societies, vegetable drinks are being sold to the public as a substitute for cow's milk. It is important to note that the nutritional quality of these drinks is not necessarily equivalent to that of cow's milk.
