This type of analysis will probably be a cornerstone in future health assessment. Since there are more cells and genes in the microbiome than in the human body, it seems reasonable that different compositions may have profound effects. Untangling this might take a while, meanwhile, changes in food production, environmental degradation and pollution are probably affecting microbial “landscapes” in detrimental ways. For now, options are limited to experimenting with diets, switching to organic alternatives, and the most radical method, temporarily change environment to isolate or eliminate the causes. All these more or less worked for me, the last one most effective, restoring a dysfunctional gut flora, however not permanently which speaks for environmental factors beyond diet.
