Two people the same age can be aging at measurably different rates, and researchers now have molecular tools to detect the difference. A study from the University of Hawaii at Manoa reports that differences in gut bacteria accounted for roughly 15 percent of the variation in how quickly participants' bodies were aging biologically.
The findings were published in Scientific Reports on July 14. Two organisms stood out. Bifidobacterium adolescentis was among the strongest microbial signatures associated with slower biological aging, while Succinivibrio dextrinosolvens showed one of the strongest associations with accelerated aging.
