The notion that the state of our gut governs our state of mind dates back more than 100 years. Many thinkers and scientists believed, that accumulating wastes in the colon triggers a state of “auto-intoxication,” at which the poisons emanating from the gut produced infections, that could be linked to depression, anxiety or psychosis. But is it really true? Do we have a cumulative scientific evidence backing the hundreds of on-line articles presented on popular health-and-diet portals? What are the other diseases related affected by lower quality of gut microbiota?
The word “microbiota” represents an ensemble of microorganisms, located in a previously established environment. Human beings have clusters of such bacteria in different parts of the body – on the surface and deep layers of skin (skin microbiota), in the mouth (oral microbiota), or in vagina (vaginal microbiota). Gut microbiota (also called gut flora) is the name given to specific microbe population living in our intestines.
