Earlier quoted context omitted.
It's not impossible, and it might even be plausible... But it's a really, really difficult question. People outside of science: don't make the mistake of thinking that scientists haven't thought about this before! haha
What is that supposed to mean?

#33About ten years ago my former PI (second author in the below paper) did quite a job on this in Burkina Faso, analyzing the composition of the gut in children living outside cities, in cities, and a comparison with European children. Obligatory disclaimer: I was working in his laboratory at the time, but I wasn't involved in that research. https://www.pnas.org/doi/10.1073/pnas.1005963107
What's a "former PI"?

Re: Modern city dwellers have lost about half their gut microbes
#38Does anyone know of probiotics with a variety of bacteria? Currently they (and yoghurts) seem to be just a single type, which doesn't make a lot of sense to me. If there are unusual bacteria out there where do they come from and how can we get them? I've done a bunch of anti-biotics in the last few years so what to get back to what I was.

#40>people in U.S. cities...people in less developed parts of the world What about people in the US who are not in cities? That's the more interesting comparison to me. Why would that be left out?
I'm curious why that comparison is more interesting to you? I can see great value in having both data points when trying to formulate a hypothesis about what causes the decline in gut-microbes in us city folks, but I find it hard to think of a use-case for solely a urban/rural comparison without other context. (Update: I was thinking about this from a scientific perspective, ignoring the idea that people might be int…
