RHR: Seed Oils and Colon Cancer – What the New Research Really Shows

RHR: Seed Oils and Colon Cancer – What the New Research Really Shows

Author: Chris Kresser December 16, 2025 Duration: 19:55

Seed oils have become one of the most controversial topics in nutrition, especially after a 2024 University of South Florida study linked high omega-6 levels with inflammation in colon tumors. In this episode of Revolution Health Radio, Chris takes a deep, evidence-based look at what the study actually means — and what it doesn’t. You’ll learn the crucial difference between naturally occurring omega-6 fats in whole foods like nuts, chicken, and avocados and oxidized omega-6 fats found in ultra-processed foods and industrial seed oils. He explains why awareness of the omega-6 to omega-3 ratio and the issues of the modern Western diet are far more important than demonizing individual oils and offers practical advice on which cooking oils to use, which to limit, how to improve omega-3 intake, and how to adopt a balanced approach to dietary fats without fear or obsession.
