Breast milk is often described as the perfect food for babies. Now new bacteria identified in breast milk has been found to help infants digest mother’s milk or give their immune system a boost, because living bacteria are crucial for good health. The recent study published in The American Journal of Clinical Nutrition has discovered more than 700 species of bacteria in breast milk – more than previously thought. It is through breastfeeding that babies make some of their first contact with the bacteria that will colonize their bodies.
Pediatricians say breastfeeding has health benefits for both infants and mothers. The boost to the immune system includes a lower risk of respiratory and ear infections, skin allergies and asthma. Breastfed babies are also better protected from SIDS (sudden infant death syndrome), diabetes and obesity later in childhood. For women, breastfeeding can decrease risk of breast and ovarian cancers.
With the new study on bacteria in breast milk, Spanish researchers used large-scale DNA sequencing to map out the species of micro-organisms. Scientists also determined the mother’s health could affect the make-up of breast milk:
There are fewer bacteria in the milk of overweight mothers or those who put on more than weight than recommended during pregnancy.
Mode of delivery
Women who have planned Cesarean sections, who do not go through labor, have fewer micro-organisms in their breast milk. Women who have unplanned C-sections have similar milk composition to women who deliver traditionally. Researchers suggest hormones during labor could influence breast milk composition.
If a mother is unable to or does not wish to breastfeed, the scientists say their study could help redesign infant formula to more closely match breast milk.
