Thanks for this article. I think it places a lot of the gut microbiome studies and findings in context.
As a note for the author in case they are reading - you should do a quick Find/Replace on the article keyed on the word "git". There is more than one instance in the text where it clearly should read "gut microbiome" (or similar) and instead reads "git microbiome".
Perhaps I am mistaken and "git" in this context is simply an acronymn for "gastro-intestinal tract". Maybe capitalization would make this more obvious to those of us not directly involved in that space or a definition of "git" somewhere in the paper that defines use of the term in that context. If that already happened then I missed it.
