Although the interaction between our brain and gut has been studied for years, its complexities run deeper than initially thought. It seems that our minds are, in some part, controlled by the bacteria in our bowels.
The gut has defenses against pathogens, but, at the same time, it encourages the survival and growth of "healthy" gut bacteria.
The vast majority of these single-celled visitors are based in the colon, where no less than 1 trillion reside in each gram of intestinal content.
Estimating the number of bacterial guests in our gut is challenging; to date, the best guess is that 40 trillion bacteria call our intestines home - partially dependent on the size of your last bowel movement (poop's major ingredient is bacteria).
