Ultra-processed foods (UPFs) are identified as the leading cause of preventable death globally. These foods are chemically altered, stripped of their natural structures, and filled with additives, sugars, unhealthy fats, and preservatives, resulting in products that offer little to no nutritional benefit while contributing significantly to chronic disease. In this episode, I talk with Vani Hari and Dr. Shebani Sethi about why ultra-processed foods are not just a health risk—they are a public health crisis. Vani Hari is the food activist behind FoodBabe.com, a NY Times best-selling author of 4 books, founder of the organic products brand Truvani, and was named one of the “Most Influential People on the Internet” by Time magazine. Hari’s viral testimony before the US Senate sparked a massive movement to stop American food companies from poisoning their own citizens with ingredients they don’t use in other countries. Hari founded Food Babe to spread information about what is really in the American food supply. She teaches people how to make the right purchasing decisions at the grocery store, how to live an organic lifestyle, and how to travel healthfully around the world. Vani has gathered hundreds of thousands of petitions to change the food system and influenced how major food giants like Kraft, Subway, Chipotle, Chick-fil-A, and Starbucks create their products, steering them towards more healthful policies. Dr. Shebani Sethi is a double board-certified physician in Obesity Medicine and Psychiatry. She is the Founding Director of Stanford University’s Metabolic Psychiatry program and Silicon Valley Metabolic Psychiatry, a new center in the San Francisco Bay Area focused on optimizing brain health by integrating low carb nutrition, comprehensive psychiatric care, and treatment of obesity with associated metabolic disease.  Full length episodes can be found here: Why the Last Thing that Should Ever Eat is Ultra Processed Foods How To Be A Food Activist In Your Own Kitchen How Does Ultra-Processed Food Affect Our Mental Health?
