Increased Exclusivity of Breastfeeding Associated with Reduced Gut Inflammation in Infants

Abstract Introduction: The development of the intestinal gut is largely influenced by early nutrition. Infant immunity is challenged by the exposure of the gut to foreign bodies, which mediate inflammation of the gut. This study assessed the levels of gut inflammation in relation to the percentage of breastmilk consumed/the exclusivity of breastfeeding in South African infants. This is the first study to examine markers of gut inflammation in infants in relation to exclusivity of breastfeeding measured by a gold standard method. Methodology: Twenty-four black South African infants were included in this study. The categorization of different degrees of exclusivity of breastfeeding was made using an objective gold standard method developed by the International Atomic Energy Agency (deuterium dilution method). Markers of gut inflammation were measured noninvasively by sampling stool from the infants averaging 6 months of age. Gut inflammation was investigated by running multiple Droplet Digital™ (Bio-Rad, He...
