Longitudinal Evolution of True Protein, Amino Acids, and Bioactive Proteins in Breast Milk: A Developmental Perspective

The protein content of breast milk provides a foundation for estimating protein requirements of infants. Because it serves as a guideline for regulatory agencies issuing regulations for infant formula composition, it is critical that information on the protein content of breast milk is reliable. We have therefore carried out a meta-analysis of the protein and amino acid contents of breast milk and how they evolve during lactation. As several bioactive proteins are not completely digested in the infant and therefore represent “non-utilizable” protein, we evaluated the quantity, mechanism of action, and digestive fate of several major breast milk proteins.
