From Peter Attia, MD:
Rick Johnson, Professor of Nephrology at the University of Colorado and a previous guest on The Drive, returns for a follow-up about unique features of fructose metabolism, and how this system that aided the survival of human ancestors has become potentially hazardous based on our culture’s dietary norms. In this episode, Rick explains how the body can generate fructose from glucose and how circulating glucose and salt levels can activate this conversion. He discusses the decline in metabolic flexibility associated with aging, as well as how factors such as sugar intake or menopause-associated hormone changes can alter responses to sugar across a lifetime. In addition, Rick lays out strategies for combating the development of metabolic illness using dietary changes and pharmaceutical therapies, and he discusses the impact of fructose metabolism and uric acid on kidney function and blood pressure. He concludes with a discussion of vasopressin, a hormone that facilitates fructose’s effects on weight gain and insulin resistance.
