Overview

Narrative review reveals how breast milk bioactives alter gene regulation in infants, highlighting potential epigenetic convergence through shared breastfeeding.

Key Points

To evaluate how breast milk bioactive components regulate early-life epigenetic programming and assess the biological plausibility of epigenetic convergence resulting from shared breastfeeding.
Synthesized mechanistic, clinical, and epidemiological evidence within the Developmental Origins of Health and Disease (DOHaD) framework.
Evaluated bioactive factors including microRNAs, extracellular vesicles, human milk oligosaccharides, hormones, and immune factors influencing infant gene expression and chromatin architecture.
Breast milk bioactives actively modulate infant DNA methylation, chromatin structure, and gene expression across metabolic, immune, and developmental pathways during critical early-life windows.
Common exposure to breast milk bioactive signals provides biological plausibility for partial epigenetic convergence among unrelated infants sharing milk, though direct human evidence remains scarce.
Longitudinal multi-omics studies integrating epigenomics, transcriptomics, and microbiomics are required to determine the functional stability and disease-prevention implications of shared lactational exposures.
