Choosing what to eat sounds simple, but as this conversation reveals, it’s anything but. Food choices are shaped by powerful industries, global supply chains, government policy, and marketing systems that rarely prioritize human or planetary health. In this episode, Alita Guillen sits down with Marion Nestle, Professor of Nutrition, Food Studies, and Public Health at NYU and one of the world’s leading voices on food policy. Marion is the author of more than a dozen award-winning books, including her latest, What to Eat Now: The Indispensable Guide to Good Food, How to Find It, and Why It Matters. Together, they explore how modern food systems influence what ends up in our grocery carts, why eating “real food” has become so complicated, and how everyday decisions, from buying coffee to choosing juice, meat, or packaged snacks, ripple outward to affect climate change, labor conditions, public health, and global hunger. Marion breaks down how supermarkets are engineered for profit, what food labels really mean and don’t mean, how ultra-processed foods quietly drive overconsumption, and why eating more plants and fewer animal products is a rare win for both personal health and the planet. She also offers practical, grounded advice for making better choices without guilt, emphasizing that food should still be a source of pleasure. At 89 years old and still writing books, Marion brings decades of perspective, humor, and clarity to a conversation that will change how you think about food, not just as fuel, but as a powerful global force.
