1. 11. Our gut bacteria are messing with us in ways we could never have imagined. New research has revealed that neurodegenerative diseases like Parkinson's might actually start out in the gut, rather than the brain, and there's mounting evidence that the human microbiome could be to blame for chronic fatigue syndrome.
