Concentrations of selected human milk components influence the infant oral microbiome to a greater degree than estimated intakes

Human milk is characterised by its complex composition, consisting of nutrient and bioactive components that play a crucial role in infant health. Although the infant oral cavity is directly exposed to these components during breastfeeding, their effects on the developing oral microbiome remains underexplored.

Abstract:
Human milk is characterised by its complex composition, consisting of nutrient and bioactive components that play a crucial role in infant health. Although the infant oral cavity is directly exposed to these components during breastfeeding, their effects on the developing oral microbiome remains underexplored.
