Infant Gut Microbiomes Exhibit Circadian Rhythms Independent of External Cues

New research shows that infant gut microbiomes have circadian rhythms, even when cultured outside the body. The study found that age plays a more crucial role in microbiome development than diet, debunking the common belief that diet significantly impacts the composition of the infant microbiome. The study also revealed that GOS-supplemented infant formula was more effective at promoting sustained levels of Bifidobacteria compared to formula containing Bifidobacteria.
