"The aim is to bring novel microbiome diagnostic systems to populations, then use food and probiotics to try and improve biomarkers of health," says study co-author Gregor Reid, a professor at Western University's Schulich School of Medicine & Dentistry and a scientist at Lawson Health Research Institute. However, the study cannot explain causality. As Prof. Reid explains, "It begs the question "if you can stay active and eat well, will you age better, or is healthy aging predicated by the bacteria in your gut?" Either way, there remains a strong and undeniable correlation between a healthy gut and healthy aging.

"The main conclusion is that if you are ridiculously healthy and 90 years old, your gut microbiota is not that different from a healthy 30-year-old in the same population." – Prof. Grg Gloor 

"Whether this is cause or effect is unknown," write the authors. However, Prof. Gloor explains, "This demonstrates that maintaining [the] diversity of your gut as you age is a biomarker of healthy aging, just like low-cholesterol is a biomarker of a healthy circulatory system." "By studying healthy people, we hope to know what we are striving for when people get sick," notes Prof. Reid.

The results of the study, the authors write, "[suggest] that resetting an elderly microbiota to that of a 30-year-old might help promote health."
