A Canadian-Chinese study on the intestional microbiome of over very healthy 1000 Chinese people, aged from 3 to 100 years, found that a healthy older person is more likely to have a young” intestinal tract microbiome composition. Gut microbe composition of an extremely healthy 90-year-old may be similar to a 30-years-old. This suggests that maintaining the diversity of the intestinal flora is a biomarker of healthy aging, just as low cholesterol is the biomarker of a healthy circulatory system, and opens avenues to introduce new microbiological diagnostic systems and then suggest adequate food and probiotics to improve healthy ageing, http://msphere.asm.org/content/2/5/e00327-17″
