Breast milk from each individual contains a unique assemblage of antibodies that are surprisingly stable throughout lactation and across pregnancies, according to a new study.
Breast milk carries personalized antibodies to babies
In a fascinating new study, researchers have discovered that a mother’s breast milk contains a personalized collection of antibodies that are remarkably consistent over time and pregnancies. It’s like each mother has her own special army of superheroes to protect her baby from infections and diseases! Just as every superhero possesses unique powers and strengths, each mother’s breast milk carries a distinctive set of antibodies tailored specifically for her baby’s needs. These antibodies act as superheroes, defending the baby against harmful pathogens and boosting their immune system. The stability of these antibodies throughout lactation and different pregnancies is truly remarkable, providing long-lasting protection for the baby.
