Nice find!!
Thanks for the share. I've only a read a bit in, but I think the exploration of gut flora seems like a really interesting field to be a part of right now.
Things like this really give a whole new meaning to phrases like "Trust your gut". So many implications and possible connections ramble in my head..
You can see why eating well and taking care of your body really matters in terms of cultivating a nice, biodiverse culture of these friends. Thinking about dietas practiced for various plant medicine practices is interesting too and how it might prime one's physiology for more powerful experiences. DMT particularly has been shown to act at the nervous system and immune 'interface', as characterized recently by the Hungarian lab. They showed a modulation of the immune system's inflammatory responses by DMT I think, and it's fun to wonder about it's ties to the gut flora/serotonergic activity.
Ramble ramble
