@kdfrawg It seems the current state of knowledge is that it’s not a great idea to kill off all those bacteria, but we don’t know another way to wipe out the ones that are making you ill, and we don’t have a reliable way to repair the damage afterwards.
So, probiotics, prebiotics, yoghurt, sauerkraut & a bit of help from Bembo is about the best we can do for now. The snazziest probiotics have a dozen or so species, compared with 12,000 or so even in our weedy modern microbiota.
