Are Plant-based Proteins Actually Superior? Iron Culture

- Salud y forma física
After their recent reconciliation, the Erics got together for this duo episode to bond over their mutual love of protein. But, dear listener, this might not be the home-cooked high-protein meal you hoped for. Dr. Trexler tackles the question of whether or not, GASP, protein restriction might extend lifespan! Then, to add insult to injury, the Erics dig into the question of whether or not plant-based protein sources could be superior to animal sources for improving healthy aging! Along the way, you’ll also learn about the limitations of both epidemiological and mechanistic protein research, and how the two can complement each other to lead to more robust conclusions. So grab your pea protein shakes - or maybe your protein-free placebo - and tune in for another monster episode of Iron Culture.
