Most people ask the wrong question. They ask: “Is olive oil healthier than seed oils?” That’s not the decision. The real question is: What fat causes the least damage when you heat it? 🫠 Heat is the constraint Cooking applies heat. Heat breaks fragile fats. Broken fats don’t stay neutral. They turn into inflammatory byproducts. So the best cooking fat is the one that stays stable under heat. 💔 Why fats break Fats break through oxidation. Oxidation increases with: - Heat - Light - Time Polyunsaturated fats are fragile. Saturated fats are stable. This difference explains most diet-related inflammation. 😵 Linoleic acid is the bottleneck Linoleic acid is a polyunsaturated fat. Because of that, it: - Oxidizes easily - Accumulates in body fat and cell membranes - Persists for years once stored High tissue levels of linoleic acid are associated with: - Chronic inflammation - Insulin resistance - Obesity - Cardiometabolic disease This isn’t about one meal. It's about long-term accumulation. 🧪 How much linoleic acid is in common fats - Butter / tallow: ~1–2% - Coconut oil: ~2% - Olive oil: ~8–12% - Avocado oil: ~15–20% - Seed oils: 50–70%+ Lower linoleic acid = less oxidation Less oxidation = lower inflammatory burden 🫒 Where olive oil fits Olive oil is better than seed oils. It contains: - Mostly monounsaturated fat - Polyphenols - Vitamin E These compounds are associated with improved lipid markers and reduced cardiovascular risk. But here’s the constraint: Olive oil still delivers meaningful linoleic acid. And heating it still accelerates oxidation. So while olive oil may be beneficial in some contexts, it is not an optimal cooking fat if the goal is lowering long-term metabolic stress. 🐮 Why animal fats and coconut oil perform better Butter, ghee, tallow, and coconut oil are predominantly saturated. That makes them: - Heat-stable - Resistant to oxidation - Far less likely to contribute to inflammatory byproducts
