Breastmilk and the Infant Microbiome
Mother’s milk, the original “superfood,” not only nourishes babies directly; it also feeds friendly gut microbes that support digestion, immune system development, and long-term health.
The resources listed here explain the composition of breast milk and how it contributes to the development of the infant gut microbiome and infant health.
Most of the articles below are open-access and freely available to the public. The only restricted article, “Daughter Dearest…” is available electronically to UC Davis affiliates while on-campus, or from offsite by logging in or using the Library VPN.
