Advances in breast milk microecology and neonatal immunity
As the most important source of nutrients for newborns,breast milk is not only rich in protein,fat,carbohydrates,vitamins,minerals and other nutrients,but also contains hundreds of bioactive factors,such as hormones,cytokines,white blood cells,immunoglobulins,lactoferrin,lysozyme,stem cells,breast milk oligosaccharides,micropopulation and microRNA.The comprehensive action of all components of breast milk can regulate the development of neonatal immune system.Various microorganisms in breast milk interact with each other to form a breast milk microecosystem.More and more attention has been paid to the role of breast milk microflora in promoting the development of neonatal immune system.This article reviews the relationship between breast milk microecology and neonatal immune function.
