Do you have a source for this? I remember seeing an article on (I think) HN about research indicating gut bacteria influences emotions which would seem to me to indicate cause rather than effect. Perhaps it’s impossible to definitively say either way. I can certainly see anxiety being the sort of thing where a feedback loop spirals out of control.
- osacial 6y agoGut bacteria affects brain, by migrating from guts to brain - IT DOES NOT AFFECT BRAIN, WHEN IT IS IN GUT! FFS, just, read those articles properly. I've read it as well, but somehow I don't think, that my gut is as smart as my brain...

A misbalance in your gut microbiome and the brain's reactions ca be influenced - e.g. cannot transmit effective enough different signals. To clear out any misunderstanding, your gut microbiome cannot 'make' you feel anything on its own. It can either make it easier or more difficult to experience certain emotions. This is an emerging field - look at these 2 publications and see how questionable the conclusions can be: https://www.nature.com/articles/nrgastro.2013.76 https://www.nature.com/articles/nrgastro.2013.76 and https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0179017 https://journals.plos.org/plosone/article?id=10.1371/journal...
