In this eye-opening episode, I am joined by renowned olive oil expert Dr. Rod Mailer to uncover the shocking truths behind one of the most misunderstood ingredients in our kitchens: olive oil.

Together, we explore the science, sourcing, and scandals behind olive oil—what it really means when a bottle says “extra virgin,” how processing and storage impact its quality, and why so much of what we buy may not be what it claims to be. We also dive into the science of why seed oils—like canola, soybean, and sunflower—pose serious health risks, and how they’ve infiltrated modern diets to a dangerous degree. Whether you’re a health-conscious consumer or just want to know what’s actually in your food, this episode will change the way you think about fat.
