Abstract:
Breast secretions of colostrum precede milk production in the first few days after birth, providing nutrition and playing a critical role in shaping the newborn's gut microbiome and immune system development. Infants fed commercial milk formula in the first few days consume less colostrum, and previous studies have found an associated increased risk of food allergy.
