Seed oils have recently become a hotly debated topic in nutrition, fueled by sensational claims on social media. In this episode, the central theme is examining whether seed oils are truly harmful or if they’ve been unjustly demonized.
The discussion tackles prevalent claims – that seed oils drive inflammation, oxidation, and chronic disease – and compares them against the current scientific evidence.
This is highly relevant to nutrition science and clinical practice today, as many patients and practitioners are encountering conflicting information about vegetable oils.
By exploring the origins of seed oils, their biochemical effects, health outcome data, and the misinformation ecosystem, the episode aims to clarify how omega-6 rich seed oils fit into a healthy diet and what evidence-based guidelines say.
