But we also have a biological age, which scientists can measure by assessing how our genes are expressed through epigenetics.This week on The Dhru Purohit Podcast, Dhru sat down with Dr. Kara Fitzgerald to talk about the exciting new research that shows that our biological age can actually move in reverse and her groundbreaking, clinical trial that proved it’s possible.Dr. Fitzgerald received her doctorate of naturopathic medicine from the National College of Natural Medicine in Portland, Oregon. She is on faculty at the Institute for Functional Medicine, and is in private practice in Sandy Hook, Connecticut. Her study Potential Reversal of Epigenetic Age Using a Diet and Lifestyle Intervention: A Pilot Randomized Clinical Trial is the first of its kind to show biological age reversal in humans.In this episode, we dive into:  -The top three things you can do to age in reverse (6:56)-Why stress is one of the biggest drives of aging (8:43) -How much of our genes are set in stone (13:17) -How epigenetics are involved in cellular aging (18:58)-DNA methylation and how it powerfully influences epigenetic expression (22:03)-Zombie cells and aging (32:35)-What we can learn from the centenarians of Sardinia (41:33) -Biological age vs. chronological age (45:56)-Dr. Fitzgerald’s study for aging in reverse (50:41)-How trauma can impact genetic expression (1:15:34) This episode is brought to you by InsideTracker, BiOptimizers, and Eight Sleep.InsideTracker looks at everything from metabolic and inflammatory markers to nutrients and hormones.
