You Are What You Eat – Starting at Birth or Even Before!
However, a recently published study by researchers at Baylor College of Medicine found no differences in the microbiome of infants at 4 to 6 weeks of age between those delivered by C-section or born vaginally. According to the researchers, one explanation is that the microbiome may actually have been established in utero from the placenta during pregnancy and even undergone some maturation prior to birth. 3,4
Infants who are breastfed after birth continue to exhibit colonization and maturation of their gut microbiome. According to a recent study from UCLA5, breast milk contributed more than 25% of the bacteria to the infant gut with an additional 10% coming from the areolar skin - findings that were most pronounced during the first month of life. More importantly, infants who continued to breast feed through 6 months of age after the introduction of solid foods had a lower incidence of obesity and asthma. Although these findings need to be corroborated, they potentially add to the body of evidence supporting the benefits of breast feeding.
