Another Ecosystem Analogy

"....The idea [is] that fewer excess carbs in the gut leads to more competition which favors indigenous gut microbes over bad or pathogenic bacteria. A good example in this paper likens friendly gut microbes to your lawn. “It is thought that our commensal, or friendly, bacteria serve as a kind of lawn that, in commandeering the rich fertilizer (carbs) that courses through our gut, out-competes the less-well-behaved pathogenic “weeds.” The more healthy grass you have, the fewer weeds will be able to become established.” But if you were to spray your lawn with roundup (like antibiotics) and continue to add fertilizer, soon you will have a weed-filled yard. According to the authors: “Resident microbes hold pathogens at bay by competing for nutrients.”
