An observational study links gut microbiome composition to anxiety and depression symptoms, though the design cannot prove causation.
A large observational study has identified associations between the composition of gut bacteria and self-reported symptoms of anxiety and depression, adding to a growing body of work on the gut-brain axis.
The authors were careful to note that the study design cannot establish causation, and that dietary and lifestyle factors may account for part of the observed relationship.
Experts not involved in the work described the findings as interesting but preliminary, cautioning against probiotic products marketed on the basis of similar research.
