The gut is also physically connected to the brain by the Vagus Nerve, which can be bound by bacterial produced molecules like the short chain fatty acids, which then send impulses to the brain to modulate our brain, which is also implicated in depression, anxiety etc!

As far as I remember as of a couple of years ago, there was good evidence of probiotics reducing depressive/anxiety symptoms in mice, but nothing significant enough for recommended diets has been found in humans yet. It’s a relatively new area so there’s lots of new trials going on etc
