Gut health is at the forefront of complaints of Americans. Some 80% of our population now recognizes some disorder within the gastrointestinal tract—everything from reflux, to food allergies, to inflammatory bowel syndrome, and inflammatory bowel diseases—we are a suffering population when it comes to gut health. 

In this episode of The Dhru Purohit Podcast, Dhru takes a deep dive into the topic of gut health with Dr. Zach Bush. They talk about how we are facing the largest disease epidemic in history due to the loss of microbiome diversity and that a connection to nature is our saving grace.
