Gut microbes are vulnerable to wide range of drugs (opens in new tab)

> to put the effect into context I'd be interested in the effect of, for example, normal food.

I bet that it's also gonna depend alot on the person, and their history. This has always stuck with me:

> After he was fired for incompetence, he took it on himself to sue the restaurant, claiming that his gastrointestinal problem, caused apparently by amoebas, was a result of his work there. Management took this litigation seriously enough to engage the services of an epidemiologist, who obtained stool samples from every employee. The results-which I was privy to-were enlightening to say the least. The waiter's strain of amoebas, it was concluded, was common to persons of his lifestyle, and to many others. What was interesting were the results of our Mexican and South American prep cooks. These guys were teeming wWh numerous varieties of critters, none of which, in their cases, caused illness or discomfort. It was explained that the results in our restaurant were no different from results at any other restaurant and that, particularly amongst my recently arrived Latino brethren, this sort of thing is normal-that their systems are used to it, and it causes them no difficulties at all.

People sure are different!

"All organisms, plants, fungi and animals/humans produce chemicals that kill bacteria, i.e. antibiotics. ... The flavoring chemicals in herbs and spices have a far more important use in food preparation than titillation of taste buds, since those chemicals kill common food pathogens. More profoundly, it is important to realize that the selective advantage of phytochemicals/polyphenols/alkaloids/essential oils to the plants that make them, is as natural antibiotics. Plants kill bacteria, as well as fungi and insects, for a living."

Yes and no? I'm sure it's a fierce fight, but AFAIK a diet of fermented foods is considered healthy, and good for digestion. So presumably a diet of fermented foods can result in some beneficial equilibrium

Yes, a battle too horrible to contemplate! Imagine the slaughter consequent on ingesting coffee,chocolate,tea,sourdough bread,cheese,buttermilk,crème fraîche,yogurt,kefir,salami,wine,beer,sauerkraut,dill pickles,kimchi,kombucha,fish sauce,vinegar,miso or tempeh.

I suggest reading the current wisdom from Dr. Les Dethlefson, human microbiota researcher at Stanford's Relman lab [0].

In the link he addresses the difference between addressing an acute condition with probiotics versus long-term maintenance of health. Your question seems to land somewhere in the middle. So see what he has to say and please remember, this is far from settled science!

I work in the microbiome field, and colleagues and i discussed this paper a few days ago. The overall impression seems to be that this is not for the practically-minded but primarily science for scientists. A lot of microbiome studies have suffered from inadequate exclusion critera because of the lack of this systematic knowledge.

I think that the best thing one can do for their microbiome is to stop trying to kill germs in everything around us. Also, when a dog wants to kiss you, accept it. They are good at maintaining theirs.

Look at the ingredients on all the products you use. Unless it's Dr. Bronner's soap or something similar, chances it's harmful to both humans and microbes. Just stop using and stop buying that shit!

Sterility is good for the operating table, but not for everyday life.

Why would you limit yourself only to probiotics when prebiotics/symbiotics exist? I recently learned about them - bear with me as I have zero experience and lack of terminology in pharma - prebiotics will create a better environment/surface for probiotics to feed on and symbiotics are both pre and pro in a single pill.

You could always opt for a fecal transplant.

If you took any of the quinolones you may have gotten floxed. The drugs are very dangerous and should only used as last resorts, according to the FDA. Mechanisms of toxicity are multiple but the common theories are iron/magnesium chelation and mitochondrial toxicity. Both of which can lead to long term severe and potentially life threatening side effects.
