Effects of Maternal Diet on Infant Health: A Review Based on Entero-Mammary Pathway of Intestinal Microbiota.

ABSTRACT

SCOPE The microbes in breast milk are critical for the early establishment of infant gut microbiota and have important implications for infant health. Breast milk microbes primarily derive from the migration of maternal intestinal microbiota. This review suggests that the regulation of maternal diet on gut microbiota may be an effective strategy to improve infant health. METHODS AND RESULTS: This article reviews the impact of breast milk microbiota on infant development and intestinal health. The close relationship between the microbiota in the maternal gut and breast through the entero-mammary pathway is discussed. Based on the effect of diet on gut microbiota, it is proposed that changing the maternal dietary structure is a new strategy for regulating breast milk microbiota and infant intestinal microbiota, which would have a positive impact on infant health. CONCLUSION: Breast milk microbes have beneficial effects on infant development and regulation of the immune system. The mother's gut and breast can undergo certain bacterial migration through the entero-mammary pathway. Research has shown that intervening in a mother's diet during breastfeeding can affect the composition of the mother's gut microbiota, thereby regulating the microbiota of breast milk and infant intestines, and is closely related to infant health.
