The Truth About Seed Oils, From a Scientist | Dr. Jessica Knurick

Dr. Jessica Knurick reveals a truth most nutrition experts won't admit: our food system is designed for profit, not health, and over half of American adults are living with chronic disease as a result. As a science-based dietitian who lost her grandfather to preventable illness at 60, she's spent her career fighting back against fear-mongering and misinformation that keeps people confused and sick. In this eye-opening conversation, she exposes why seed oils aren't the villain everyone claims, how ultra-processed foods hijack your brain to make you overeat 500 calories a day, and why the most effective health advice is actually boring. You'll walk away understanding that 90 percent of nutrition science is settled and simple, but social media algorithms profit from making you believe everything is controversial and complicated.
