Seed oils are not toxic; they should be consumed in moderation as part of a diet composed primarily of whole foods, without giving in to media-driven fear.

The current scientific consensus does not support the idea that seed oils (such as sunflower or rapeseed oil) are metabolic poisons. A meta-analysis published in 'Circulation' (AHA) confirms that replacing saturated fats with polyunsaturated fats, which are present in these oils, is associated with a reduction in cardiovascular risk. The evidence is derived mainly from observational studies and robust randomized controlled trials (RCTs). The claim that they are systematically inflammatory is widely considered to be exaggerated or unproven in humans at usual doses. The scientific focus is instead on the quality of industrial processing and the overall balance of omega-6 and omega-3 intake, rather than the intrinsic toxicity of the oils themselves. Michael Israetel favors an approach here based on 'big rocks' (the foundations of nutrition), which aligns with public health recommendations.
