I read on this site: http://digestivehealthinstitute.org/2014/03/24/resistant-starch/#_edn11 that prevotella growth can be exacerbated by RS. This is troubling to me because I already know that prevotella tends to be overgrown for me (via fecal testing). In fact, I am on long term metronidazole and sometimes I suspect that the reason it makes me feel better is because it keeps the prevotella at bay. I don't want to go against that by taking RS if it make prevotella worse, though. Thoughts?
