The Science of Breast Feeding
Summary
Luke O'Neill explores the biochemistry and evolutionary origins of breast milk, highlighting its unique role in infant nutrition, microbiome development, and immune defense through antibodies and live cells. He compares breast milk to formula, noting that while formula is nutritionally adequate, breastfeeding offers superior protection against infections and provides health benefits for mothers, including reduced breast cancer risk. The episode concludes with a call for increased public health support and resources to help more women successfully breastfeed.
