"Infant Gut Microbiomes Sync with Circadian Rhythm"
Infant gut microbiomes develop circadian rhythms as early as two weeks after birth, becoming more distinct with age and showing resilience and adaptability independent of external cues. A study with 210 infants found that diet plays a secondary role to age in influencing microbiome development, challenging previous assumptions about nutrition's impact. The research also revealed rhythmic 24-hour fluctuations in microbiome species abundance and metabolites, with breast milk and GOS-supplemented formula impacting gut metabolite profiles differently. This study opens new avenues for understanding gut health and its implications for human well-being.
