Why Do Most Diets Fail? The Science of Nutrient Deficiencies | Ty Beal PhD

<p>In this episode, I’m joined by Dr. Ty Beal—global nutrition researcher and Senior Technical Specialist at the Global Alliance for Improved Nutrition (GAIN)—to uncover the hidden epidemic of micronutrient deficiencies worldwide. From food access and affordability to ultra-processed diets and nutrient bioavailability, we explore how modern food systems are failing billions and what needs to change to truly make the world healthier.</p><p>We cover:</p><ul><li>Why 3 billion people can’t afford a healthy diet—and how that affects nutrient status</li><li>The most common global and U.S. micronutrient deficiencies (and why they’re often overlooked)</li><li>Why women and children are especially vulnerable during pregnancy, infancy, and adolescence</li><li>The role of ultra-processed foods in displacing nutrient-rich options</li><li>How bioavailability, anti-nutrients, and the “food matrix” impact your real nutrient intake</li><li>Why plant-based diets aren’t always safer—and the hidden risks...
