‘Ridiculously healthy’ elderly have the same gut microbiome as healthy 30-year-olds, by Science Daily.

In one of the largest microbiota studies conducted in humans, researchers at Western University, Lawson Health Research Institute and Tianyi Health Science Institute in Zhenjiang, Jiangsu, China have shown a potential link between healthy aging and a healthy gut. …

The results showed a direct correlation between health and the microbes in the intestine. …

“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,” said Greg Gloor, the principal investigator on the study … Whether this is cause or effect is unknown …

“This demonstrates that maintaining 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,” Gloor said. The researchers suggest that resetting an elderly microbiota to that of a 30-year-old might help promote health.
