The milk (in Latin: lac, 'milk')? Is an opaque whitish nutritional secretion produced by the secretory cells of mammary glands or mammals of females of mammals, including monotremes.1 2 3 4 The main function of milk is to nourish the young until they are Capable of digesting other foods, in addition to protecting their gastrointestinal tract against pathogens, toxins and inflammation, and contributing to their metabolic health by regulating the processes of obtaining energy, especially the metabolism of glucose and insulin.5 This capacity is one of the Characteristics that define mammals. It is the only fluid that the offspring of mammals (from the infant of the breast in the case of humans) ingest until weaning. The milk secretion of a female in the days before and after calving is called colostrum.
Milk from some of the domestic mammals (mainly cows but also buffalo, sheep, goats, mare, camels, elk, sows and others) are part of the common human diet in some cultures, the basis of numerous dairy products, Such as butter, cheese and yogurt, among others.6 The use of milk derivatives in the agri-food, chemical and pharmaceutical industries, such as condensed milk, milk powder, casein or lactose, is very common. Cow's milk is also used in animal feed. It is composed mainly of water, ions (salt, minerals and calcium), carbohydrates (lactose), fat and protein.2 There is evidence that milk from almost all mammals (including humans) contains morphine derivatives Called casomorphins, which are responsible for maintaining a certain level of addiction in infants to stimulate their appetite, as well as reassure them in their early stages of new life. These substances could explain why many people are addicted to milk or its derivatives even in adulthood. Milk from marine mammals, such as whales (for example), is much richer in fats and nutrients than that of terrestrial mammals
