European molecular biologists found that an important factor in the creation of intestinal microflora in newborns is the PNGA enzyme. The research results may become the basis for developing methods to support healthy microflora in young children. University researcher Lucy Crouch emphasized that breast milk contains many components that cannot yet be fully reproduced in artificial milk formulas. According to her, studying substances that stimulate the growth of beneficial bacteria will help bring the composition of such products closer to breast milk and ensure a more natural formation of intestinal microflora in babies. As the researchers explain, breast milk is not only a source of fats and carbohydrates. It contains a large number of biologically active molecules involved in the establishment of the child's developing immune system, affecting its interaction with intestinal microorganisms and regulating the formation of the microflora. Therefore, scientists continue to study the specific effects of breast milk on the baby's body and its differences from artificial formulas. I will add why breast milk (and not formula) is the most effective medicine on the planet In 1981, the 34th World Health Assembly adopted resolution WHA34.22, which included the International Code of Marketing of Breast Milk Substitutes. In turn, many studies (and systematic reviews) have shown that formula feeding not only leads to rapid weight gain, but also significantly increases the likelihood of childhood obesity in adulthood. Breast milk contains many complex bioactive molecules that allow the mother to continuously support the growth and health of her baby, such as: - a large number of essential growth factors (for example, those that contribute to the development of the digestive system,1,2,3,4).
