You can totally disagree till the cows come home but that does not change the fact that probiotics either in cultured food or store bought will not implant and will not cure dysbiosis.
And you can claim I am wrong all day long while you patiently wait for the tooth fairy to come leave a quarter under your pillow. But you need to know that the tooth fairy does not exist, and there is no real basis for your claim.
Do you have any clue to how many functions the intestinal flora provide for the body? If the bacteria were not present in the intestines all the time we would be in some serious trouble if we survived at all.
These beneficial effects are part of the real science. So is the fact that the intestines also harbor bad bacteria and other pathogens. Again if it were not for the CONTINUAL presence of these beneficial bacteria these pathogens would do us in if the toxins they help break down don't get us first.
Again according to your hypothesis the intestines would be completely sterile of beneficial bacteria in a short time if someone goes on a fast. Yet this does not happen. So how does your fairytale version of "science" explain this discrepancy? For that matter how do you think babies who are not breast fed survive without any beneficial flora since they don't get any from formula? Why don't you stop and really think about the facts before going off telling other people they are wrong?
