Breast milk has long been known to play an important role in increasing the resilience of the baby’s body. Greatest compositions contained in milk is lactose (50-60 g / L), followed by fat (30-50 g / L), oligosaccharides (10-12 g / L), and protein (8-10 g / L).
Milk plays an important role for the development of good bacteria in the gastrointestinal tract. Breast milk contains oligosaccharides are not digested by enzymes, so that remains there as prebiotics in the gut. Furthermore, these prebiotics in the gut will be metabolized by bacteria that dominate the gastrointestinal tract in infants who are breastfed.
However, what exactly is meant by the good bacteria? Good bacteria in question is the flora Bifidobacteria. The flora associated with increased susceptibility to infection in the digestive tract and play an important role in the development of a healthy immune system and the induction of oral tolerance.
Further explained also that these good bacteria have beneficial effects on health due support optimal function of the gastrointestinal tract, reduce bad bacteria colonies, and strengthen the immune system.
Layer supports gastrointestinal (gut barrier)
This function is very important because the baby’s digestive tract defense mechanisms against pathogens is still not well developed, so that can cause serious illness in infants. Mucosal lining keep bad bacteria can not get into the bloodstream and the body and hold allergens to enter the blood so as to prevent the occurrence of allergies. Bifidobacteria helps keep the gastrointestinal tract by producing short chain fatty acids (SCFA). SCFA is the source of energy for gastrointestinal cells, so the cells can produce a more viscous mucus.
Lowering bad bacteria colonies
Bifidobacteria also produce acids (acetate and lactate) that lowers the pH of the gastrointestinal tract. Made acidic intestinal environment to be anti-bacterial and suppress the growth of bad bacteria. These bacteria suppress the growth of bad bacteria compete for nutrients in the gastrointestinal tract.
Supports the immune system
Bifidobacteria supports the development of the GALT (gut associated lymphoid tissue) which is 2/3 part of the immune system. Bifidobacteria affect the amount and distribution of GALT cells that play an important role in the maturation and regulation of the immune system.
From the description, it is clear that Bifidobacteria are necessary to improve baby’s immune system and fight bad bacteria.
