Enhanced analysis of Genova Report

A reader forward me their latest report and it would be good to show how you can work from it.

Standard Items

Classic desert of key bacteria…




So my matching deep-dive pages are (ignoring the lows):

Bottom Line Theoretical Items

The lists below are done by merging the lists from the deep dives linked above. Some items may encourage one genus and discourage another genus — those are placed in inconclusive. The impact on Lactobacillus, Bifidobacterium and E.Coli are intentionally ignored [See this post for the logic]. This is all based on applying logic to the results of studies — thus theoretical. The last one was only partially done because high levels are often deemed to be good. This is an addition (not a replacement) to this overview post.


In general, should try to avoid (helps some, inhibits some — we do not know the balance). These could be tried in isolation to other changes to infer their impact on your own microbiome.
