Dr. Paul Mason - Peak Human Podcast


Listen on


Hi again everyone, another week has begun! We’ve slipped into season 7 without a break in the action. There’s no time for a pause, there’s so many interesting people to talk to. If you're new to this podcast, I’m Brian Sanders and I'm making a film called Food Lies that goes to the beginning of human history to find out what we should be eating. We go through all the bad science that has led us astray, the new science that vindicates ancestral eating, and we even get into how we can eat meat in a not only sustainable way, but one that it is regenerative to the environment. All of these topics have been covered in the last 83 episodes of this podcast, so please start back at episode 1.

Today Dr. Paul Mason and I get into a wide variety of topics including salt, blood pressure, lectins, gluten, intestinal permeability, the microbiome, fiber myths, autoimmune issues, animal based diets, and we end on how this all lines up with staying healthy and protecting yourself from viruses like COVID-19. Get out your notepad for this one!
