“In a coarse way, dirty living is good for you and clean living is bad for. You are part bacteria, if you got rid of the life on your skin or in your gut, you would almost certainly die. But, what I had envisioned was an expansion of the slightly more complex idea called the hygiene hypothesis, whose argument goes something like this… Humans moved from rural lifestyles outdoors to hyper-clean lifestyles indoors in city apartments with central air, sealed windows and surfaces scrubbed clean, at every opportunity, with antimicrobial wipes. That transition led us to spend less time getting “dirty” outside. It also “cleaned up” many of the species we need around us indoors that would allow us to get dirty with life. This combination prevented many of our immune systems from developing normally. As a consequence, our immune systems tend to get “messed up” when we live in cities. They revolt against us in the form of asthma, allergies, Crohn’s disease, inflammatory bowel disease and, depending on who you ask, maybe even MS and autism. In other words, clean living of one sort or another may be at the root of the majority of modern, chronic, diseases.” Eating off the floor: How clean living is bad for you
