In this week's series of The Brain Warrior's Way Podcast, we are honored to have friend of the show Dr. David Perlmutter return for a discussion centered around his new book "Brain Wash." Dr. Perlmutter and the Amens explain the fascinating reason why the poor decision-making and 'us vs. them' mentality in our society could be attributed to the changing function in certain areas of the brain as a result of our highly inflammatory diet.
