A new study by scientists at Nova Southeastern University (NSU) in Florida (USA) shows that poor sleep is linked to poor gut microbiota diversity, which in turns affects overall health.
A recent study, from researchers at University of California-Los Angeles (UCLA), provides further evidence that a correlation exists between the gut microbiota composition and emotional and behavioural responses.

To what extent targeting the gut microbiota as a potential treatment for depression and anxiety is unknown. A new systematic review and meta-analysis of 34 controlled clinical trials concludes that probioticsbut not prebioticsmay exert potential antidepressant and anxiolytic effects.
The effects of antidepressants are partly mediated by specific gut bacteria in mice

Researchers at KU Leuven in Belgium have found most human gut bacteria produce neurotransmitters, which are chemicals (e.g. dopamine and serotonin) that let neurons communicate with each other.
A large study of Belgian and Dutch people finds new associations between gut microbes and depression

Alterations in the crosstalk between the gastrointestinal tract and the nervous system could play a role in the global obesity pandemic. New findings shed light on the role of the probiotic Bifidobacterium pseudocatenulatum CECT 7765 in restoring behavioral changes found in diet-induced obesity in mice.
