Dr Hyman is not just a silly GP out there, you can research that. The idea that the health of the gut is related to inflammatory and autoimmune conditions is not new, has been researched over 70 years ago too.
Just wondering, what do you know about this? Have you ever had a GP talk to you about the huge importance of what you eat for your PBC and related conditions? Or about the connection between gut /digestive conditions and autoimmunes? Leaky gut syndrome, among many others?
