How diet and gut bacteria interact with the gut-brain system and their possible treatments for mental health disorders

Updated

Abstract

Dysbiosis is increasingly associated with neurological, psychiatric, and neurodevelopmental disorders, including Alzheimer's disease and depression.

  • The gut microbiota influences host health through the microbiota-gut-brain axis, impacting immune, metabolic, and neuroendocrine functions.
  • Diet significantly shapes the gut microbiota, affecting microbial composition and the production of neuroactive compounds.
  • Experimental studies suggest mechanisms linking gut microbiota to brain function, such as immune system modulation and signaling through the vagus nerve.
  • Human studies face challenges due to genetic diversity, dietary differences, medication effects, and other lifestyle factors.
  • Microbiota-targeted interventions like precision nutrition and probiotics show potential but also have current limitations.
