FAQ: The Seed Oil Audit<\/strong><\/h2>\n\n\n\n

Q: Aren’t vegetable oils “heart-healthy” because they are plant-based?<\/strong> A:<\/strong> “Plant-based” is a marketing term, not a biochemical one. Industrial seed oils are highly processed (RBD: Refined, Bleached, Deodorized) using petroleum-derived solvents like hexane. The 2026 guidelines now classify them as primary markers of NOVA Group 4 (Ultra-Processed Foods)<\/strong>.<\/p>\n\n\n\n

Q: What about the “Smoke Point”? I thought seed oils were better for high-heat cooking.<\/strong> A:<\/strong> This is a common metric error. Smoke point only measures the temperature at which an oil produces visible smoke; it does not measure Oxidative Stability<\/strong>. Saturated fats (tallow, butter) are far more resistant to the creation of toxic lipid metabolites when heated, even if their smoke point is lower than refined oils.<\/p>\n\n\n\n

Q: Why is there a “Firewall” against these oils now?<\/strong> A:<\/strong> Because of the Linoleic Acid Half-Life<\/strong>. Linoleic acid (the primary fat in seed oils) accumulates in human tissue with a half-life of approximately two years. This means the inflammatory impact of these oils can persist in your cell membranes long after you stop eating them.<\/p>\n\n\n\n

Q: Is Canola oil different?<\/strong> A:<\/strong> While marketed as “heart-healthy,” Canola oil still undergoes the industrial RBD process and contains significant PUFA content. The 2026 audit treats it as an industrial formulation that should be avoided in favor of mechanically pressed fruit oils like Olive or Avocado.<\/p>\n","protected":false},"excerpt":{"rendered":"
