Studies Clear Seed Oils of Inflammation Claims as 0.3% of Linoleic Acid Converts in the Body

Summary
Higher omega-6 intake is not linked to more inflammation; studies cited in the report instead associate it with lower inflammation and reduced cardiovascular disease and type 2 diabetes risk.
Linoleic acid—the main target of criticism—converts to Arachidonic acid at only about 0.3%, undercutting claims that seed oils broadly drive chronic inflammation.
Toxicity claims also lack support: Hexane used in extraction is removed to trace levels, and harmful compounds from heating would require temperatures above seed oils’ roughly 250°C smoke points for prolonged periods.
Seed oils are classified as processed culinary ingredients rather than ultra-processed foods, and the report says replacing them with animal fats such as butter would raise saturated fat intake and cardiovascular risk.
The broader takeaway is to focus less on demonizing single nutrients and more on overall diet quality, including adequate omega-3 intake alongside unsaturated plant fats.
