The Biology of Breast Milk

Published: Aug. 25, 2020, 8:38 p.m.

This episode aims to be the most comprehensive compendium on the biology of breast milk ever recorded. Looking at the converging clinical and animal evidence of the impact of breast milk paints a complex and beautiful mosaic of developmentally supportive effects that range from allowing the mother to act as a “compensatory” immune system to possibly supporting the development of entire organ systems through the integration of maternal stem cells found in breast milk.
