Breastfeeding benefits: Human breast milk ingredient adjusts to optimize for beneficial gut bacteria over time

Breastfeeding benefits: Human breast milk ingredient adjusts to optimize for beneficial gut bacteria over time: A new study shows that human milk oligosaccharides, or HMO, produce short-chain fatty acids that feed a beneficial microbial population in the infant gut. Not only that, the bacterial composition adjusts as the baby grows older and its needs change. For the first time, scientists have shown that a complex mixture of HMO and a single HMO component produce patterns of short-chain fatty acids that change as the infant gets older.
