The director of the M Clinic in Virginia, Dr. Bush has published peer-reviewed articles and book chapters in the areas of infectious disease, endocrinology, and cancer.

In this podcast Rich Roll interviews Dr. Bush. Roll reports "This is a mind-blowing conversation that explores new insights into the mechanisms behind human health and longevity. It's about the massive and misunderstood impact of industrial farming, chemical pesticides, the pharmaceutical industry and even errant Western medical practices have on both human and planetary health."

"It's a conversation about the difference between the science of disease and the science of health. It's about the microbiome as a critical predictor of and protector against illness. And it's an exploration of autism, epigenetics and the mechanics of intercellular communication."
