In this episode of Bulletproof Radio, my guest is Dr. David Perlmutter, a board-certified neurologist and fellow of the American College of Nutrition. He’s spent his career focusing critical attention on brain health, lifestyle and nutrition that maintains health and prevents diseases.We spend time discussing the coronavirus impact on physical and mental health, as well as ways to keep the immune system going strong.“Fear destroys immune function, and so does lack of sleep, so does eating poorly, and all of these threaten our first line of defense,” Dr. Perlmutter says. “We can make decisions either from an impulsive part of the brain, the amygdala, that are short term and really interested only in “myself,” or we can tap into the prefrontal cortex and make decisions that have much more long view.”Dr. Perlmutter’s also a New York Times bestselling author of multiple books. His newest was co-written with his son Austin Perlmutter, M.D. Brain Wash: Detox Your Mind for Clearer Thinking, Deeper Relationships, and Lasting Happiness approaches America's growing epidemics of chronic illness from a simple premise: “We know what we need to do for better health and happiness, but our ability to make good decisions has been hijacked by unhealthy digital media usage, processed food, lack of sleep, chronic stress, and other aspects of modern life—and our physical and mental health is suffering.”He shows you how to recognize the negative impact of these exposures and then offers a set of practical interventions for reclaiming your brain and improving your health.As for coronavirus? “The sooner we realize that the party's not going to resume in the near term, and that life is forever going to be changed in our world, the better we can take a deep breath and become pragmatic and make decisions from the prefrontal cortex,” Dr. Perlmutter says.Enjoy the show!Get links, resources and show notes at Dave.Asprey/podcasts.Watch the Instagram live Q&A video of Dave and Dr. Perlmutter on YouTube.
