How Bacteria Are Changing Your Mood
The brain is the most complex object in the known universe so how could it be reacting to bacteria in the gut?
-One route is the vagus nerve, it's an information superhighway connecting the brain and the gut.
-Bacteria break down fibre in the diet into chemicals called short-chain fatty acids, which can have effects throughout the body.
-The microbiome influences the immune system, which has also been implicated in brain disorders.
-There is even emerging evidence that gut bugs could be using tiny strips of genetic code called microRNAs to alter how DNA works in nerve cells.
