A study conducted by researchers from the University of Hawaii at Manoa revealed a link between certain types of gut bacteria and the speed of biological aging in humans. Differences in the composition of gut bacterial communities accounted for approximately 15 percent of the variation in aging rates among participants.
The science website Science Daily reported on Tuesday that the study, published in the journal Scientific Reports on July 14, analyzed blood samples from 123 adults and found an association between gut microbiome composition and the "DunedinPoAm" index used to estimate the speed of biological aging.
The results showed that Bifidobacterium adolescentis was associated with a slower rate of biological aging, while Sussivefibrinus dextrinosulfan was associated with a faster rate. The researchers noted that the gut microbiome is influenced by multiple factors, including diet, physical activity, medications, stress, and the environment.
The researchers emphasized that the results reveal an association between gut bacteria composition and biological aging markers, but do not prove that these bacteria cause accelerated or slowed aging. They pointed out the need for further studies to determine the mechanisms explaining this relationship.
The study provides new insights into understanding the relationship between gut health and aging, opening the door for future research to explore the role of the microbiome in supporting health as people age, without implying that current results mean aging can be slowed by changing gut bacteria types.
