Healthy Bacteria and the Intertwingularity

I read this Mother Jones article this morning, Are Happy Gut Bacteria Key to Weight Loss? Reading it made me very happy, as so many different strands of knowledge were pulled together. Ted Nelson said "Everything is deeply intertwingled" (Intertwingularity at Wikipedia), and seeing it makes the treated subject more plausible to me (as does citing scientific studies that control for some bias). And that makes me twingle!
