Fatty acids in breast milk linked to early baby brain development

Gut-Brain Axis Weekly Brief ↗PubMed ↗DOI ↗

Updated Nov 2, 2026

Abstract

Population-based evidence on odd-chain and branched-chain fatty acids (OBCFAs) and their link to neurodevelopment is limited.

Odd-chain and branched-chain fatty acids are associated with human gut bacteria.
These fatty acids may have a role in influencing neurodevelopment through the microbiota-gut-brain axis.
Current understanding of the relationship between OBCFAs and neurodevelopment is not well-established.
