Breast milk secrets revealed: study tracks sugars and microbes

This study looks at how the sugars, fats, and proteins in breast milk change from mother to mother and over time. Researchers want to see how these differences, along with the mother's diet and health, affect the development of the baby's gut bacteria. About 395 pregnant women who plan to breastfeed for at least 6 months are taking part. No treatments or drugs are given—this is purely an observation study.
