Description
Tim Wehnes and co-authors present a 2025 study of mouth bacteria, body age, and thinking in the oldest old. The group held 311 adults aged 85 and up, most of them Chinese, living in the community. Body age was read from DNA marks by four known aging clocks. Mouth bacteria were typed by gene reads, and mind and body function were scored by standard tests.
People whose body age ran young for their years held a less varied mouth mix. No single germ kind passed strict proof bars. Still, germ kinds that make short fatty acids leaned with both age gap and marks on brain-linked genes. One such kind tracked with better mind scores. Mouth care may join the map of healthy late aging.
