Mother's breast milk contains a large number of secreted human immunoglobulin, which can protect the respiratory tract and digestive tract mucosa of newborns, and also contains a large number of lactoferrin, reticulocytes, neutrophils and histiocytes, which can prevent the metabolism and reproduction of germs and their swallowing and solve various microbial strains, giving the baby a natural passive immunity.
Compared with mature milk, human colostrum contains less fat, but contains protein, fat-soluble biological substances and higher inorganic substances. The human immunoglobulin in the first sip of milk is just the best food for newborn children, which will protect them from the influence of bacteria. In addition, the first sip of milk also contains a lot of antigens and white blood cell count, which is the evil force for newborn babies to resist many diseases. The first sip of milk contains nutrients such as iron, copper and zinc that are indispensable for newborn babies. This will be very beneficial to the baby's nutrition and healthy and happy growth. Therefore, raw milk has multiple effects of nutrition and immunity. Although the secretion of newborn milk is small, it is enough for normal babies. Pregnant women should cherish their first sip of milk and never throw it away. It can make newborn babies start sucking their breasts from mammary gland secretion, even before mammary gland secretion, which can effectively preserve the first milk and promote pregnant women to metabolize more first milk.
The first sip of milk contains five times more protein than normal milk, mainly whey protein powder, which is very easy to absorb and digest, and plays an important role in promoting the growth of newborn babies. In particular, it contains more abundant and diverse human immunoglobulins, lactoferrin, cell growth factors, phagocytes, neutrophils and neutrophils than ordinary milk. This substance can prevent infection and improve immunity. Among them, the immunochemical substance of secretory IgA can cover the baby's immature inspiratory and digestive tract mucosal surface like paint, avoiding the adhesion and invasion of Escherichia coli, typhoid Bacillus and virus infection and causing digestive tract diseases, and improving the baby's human immunity and immune ability; There is lysozyme in the first sip of milk, which also has the function of preventing germs and virus infections from invading the baby's body.
Raw milk also contains a large number of cell growth factors, especially epithelial growth factors, which can promote the growth and development of squamous epithelial cells in digestive tract of newborn babies, promote the rapid growth and development of squamous epithelial cells in liver and other tissues, and regulate the pH of gastric acid. In addition, the first sip of milk has the function of relieving diarrhea, which is beneficial to the metabolism of fetal feces. The first milk can promote lipid metabolism and reduce the occurrence of jaundice in infants.
