A groundbreaking study reveals that breast milk is a powerhouse for infant gut health and brain development. Researchers found that breast milk proteins regulate immune function and help diversify gut bacteria in newborns, offering superior protection compared to formula. Even partial breastfeeding can significantly benefit infants, with 30-40% of a very-low-birth-weight infant's gut microbiota originating from mother's milk.
The study highlights that breast milk contains essential nutrients, vitamins, and hormones crucial for newborn development. Specific proteins like OPN and κ-casein influence the abundance of intestinal microorganisms in infants. Direct breastfeeding enhances microbial transmission, even in the face of antibiotic exposure.
Moreover, breast milk intake is directly correlated with greater microbial diversity in the infant gut, potentially improving long-term health outcomes. These findings could revolutionize infant formula design, aiming to replicate breast milk's unique properties more closely.
