The discovery of many novel anti-microbial peptides in human breast milk

This is the first time that a study has shown a vast amount of new peptides in human milk [1]. Founder Nora Khaldi and co-authors (Dallas, D. et al.) not only show that some breast milk proteins are digested into peptides prior infant digestion, but that many of these carry extroardinary anti-microbial functions as a protective shield to the breast fed infant.
