Gut health and ageing: a look at whether the microbiome might influence how we age

Researchers and clinicians are exploring whether the gut microbiome influences ageing, and the author visited St Mary’s Hospital to discuss personal gut analysis with Dr James Kinross.

Guts have become a source of public interest, with influencers and some food brands promoting products said to support good bacteria. Many doctors think the gut microbiome may influence a range of health outcomes, including mental health and the likelihood of some cancers. One question under study is whether the microbiome affects how well people age. The author visited St Mary’s Hospital in London to learn about personal gut analysis from Dr James Kinross, a surgeon at Imperial College London who examines stool samples. Key points: - Social media influencers promote supplements and some brands advertise products meant to nourish ‘good bacteria’. - Many doctors think the gut microbiome might affect mental health and the likelihood of certain cancers. - Scientists are examining whether the gut influences ageing and related health outcomes. - The author went to St Mary’s Hospital in London to explore personal gut analysis. - Dr James Kinross is a professor in surgery at Imperial College London and a practising colorectal surgeon who analyses stool samples. - St Mary’s Hospital is noted for its historical link to the discovery of penicillin. Summary: Scientists and clinicians are investigating whether the gut microbiome influences aspects of ageing, but clear conclusions have not been reached. Undetermined at this time.
