Live longer and live better through science- Dr. Kara Fitzgerald joins on episode 44 of the Practically Healthy podcast to share that “our genes are not our destiny” and the implications of her groundbreaking scientific trial showing biological age reversal in humans.   The doctors explain the difference between chronological age (your age in years) and biologic age- the age of your cells that determines why people may have a more youthful appearance, feel younger and most importantly, a lower risk of every major disease, since aging is the biggest contributing factor for each.   Dr. Fitzgerald explains that DNA methylation is one of the main ways we influence which genes get "turned on” and “turned off”, which is influenced by lifestyle factors. By favorably influencing DNA methylation, we can not only reduce biological age, but increase our health span and lifespan.   You’ll learn the top methylation accelerators including drinking alcohol, lack of sleep, stress along with methylation decelerators- exercise, quality sleep, decreasing sedentary activity and nutrition which is one of the most powerful ways to influence methylation. The doctors highlight a food first approach and share foods (including herbs and spices!)  that help slow aging and maximize your genetic potential- tune in to hear their top recommends!   Learn more about Dr. Fitzgerald and her body of work at drkarafitzgerald.com or follow @drkarafitzgerald. Dr. Fitzgerald also hosts a podcast called “New Frontiers in Functional Medicine, Longevity, Epigenetics” where she discussed the science and research behind medicine, longevity, epigenetics and more.
