Seed oils are not harmful to the body and prove more beneficial for our long-term vitality than saturated fats such as butter, provided they are consumed as part of an unprocessed diet.

The creator relies on a large-scale cohort study published in the journal JAMA Internal Medicine (2025, PMID 40048719), which followed more than 220,000 adults for 33 years. This observational work shows that replacing butter with vegetable oils (including canola and soybean) is associated with a notable decrease in the risk of death. Furthermore, several meta-analyses of randomized controlled trials (such as that of Wang et al., 2023 in Foods) confirm that linoleic acid—the primary omega-6 in these oils—does not increase bodily inflammation. On the contrary, these clinical studies indicate that it helps favorably regulate circulating fat levels. The poor reputation of these oils stems from theoretical models regarding inflammation that have not been verified in actual human testing. Although the 2025 study is observational and involves complex lifestyle variables, the global consensus confirms that incorporating quality seed oils in place of saturated animal fats supports our fitness and well-being.
