The community of microbes in the human gastrointestinal tract is vast and very influential on human health and well-being. The gut microbiome has been linked to a wide range of health conditions and biological systems. Now, researchers have connected the gut microbe to healthspan, aging, and longevity. A study published in Scientific Reports<\/a> has determined that changes in bacteria may explain around 15% of the differences in biological aging from one study participant to another.\u00a0<\/p>\n

“This study advances our understanding of the relationship between the gut microbiome and biological aging,” said senior study author Alika K. Maunakea of the University of Hawai\u02bbi at M\u0101noa\u2019s John A. Burns School of Medicine.<\/p>\n

“We found that microbial patterns in the gut were significantly associated with molecular measures of aging, even after accounting for chronological age. These findings open important new directions for understanding how modifiable biological systems influence long-term health trajectories and longevity.”<\/p>\n

In this study, the scientists assessed blood and stool samples, to capture a variety of biomarkers and DNA from blood, and the composition of the gut microbiome from the stool. The researchers identified the gut microbes carried by individual participants and biomarkers of aging, instead of relying on chronological age; one biomarker in particular called DunedinPACE is specifically meant for estimating the rate of biological aging.\u00a0<\/p>\n

The research indicated that some gut bacteria have very significant links to aging trajectories. For example, Bifidobacterium adolescentis had a strong association with slower biological aging in carriers. But aging was accelerated in carriers of Succinivibrio dextrinosolvens.<\/p>\n

“The gut microbiome is highly responsive to lifestyle, diet, environment and other everyday exposures,” said first study author Braden P. Kunihiro. “Our findings suggest that the microbiome may reflect important aspects of biological resilience and aging in ways that could eventually help inform future wellness and healthy aging strategies.”<\/p>\n

This study has not yet shown that any of these bacterial strains are directly slowing or accelerating again, however. More research will be needed to establish causal links between aging rates and certain gut microbes.<\/p>\n

“This is an important early step toward understanding the gut microbiome’s relationship with healthy aging,” Maunakea said. “Future research will help clarify the mechanisms involved and whether these microbial signatures may eventually contribute to precision approaches for promoting long-term health and wellness.”<\/p>\n
