“Mother’s milk holds a mix of 200-plus oligosaccharides that can change from one day to the next”. I have liked this line as it states how complex the human body is and how the breastmilk can change in function of the baby’s needs! I have always found the breastfeeding a very interesting phenomenon.The paper state that the breast milk can protect the babies from necrotizing enterocolitis, which is a common fatal intestinal disorder. The breast milk has also antibacterial activity against Group B Streptococcus and other bacteria along with antibiofilm activity against a drug-resistant Staphylocccus aureus strain.
