What if the secret to thriving in your 70s and beyond started with what’s on your plate in your 40s? In this episode, we unpack a groundbreaking 2025 Nature Medicine study that tracked the diets and health outcomes of U.S. health professionals over three decades. Researchers explored how eight different eating patterns impacted cognitive function, physical and mental health, and the ability to live disease-free past age 70. You’ll learn which diets came out on top (hint: plant-forward wins again), why ultraprocessed foods may be aging you faster, and how the Alternative Healthy Eating Index became the star of the study. Tune in for science-backed insights on how your daily meals could shape a healthier, longer life.
