Stop Cooking With These: A Longevity Physician’s Guide to Seed Oils & Saturated Fat
We’ve been told the same story for 50 years: "Saturated fat is bad, vegetable oil is heart-healthy." But if that’s true, why are we in a global energy crisis of chronic fatigue and metabolic stalling?
As a longevity physician, I look at the body like an engineer looks at a high-performance machine. When the engine stalls, I don't blame the driver—I look at the fuel. In this masterclass, we dismantle the "Fat Wars" with clinical nuance. I explain why the Seed Oil debate is often missing the most dangerous variable: Oxidation. We explore the "Two-Hit Theory" of heart disease, how unstable fats create "zombie" membranes in your mitochondria, and why your Air Fryer might be an oxidation accelerator. Most importantly, I provide a practical kitchen protocol to help you rebuild your biology from the cell membrane out.
In this episode, we cover:
• The Two-Hit Theory: Why LDL volume is only half the problem (and why oxidation is the match that lights the fire).
• The Membrane Theory: How Linoleic Acid creates "fragile" cells that leak toxic waste (4-HNE) into your brain.
• The Migraine Connection: New NIH data on how specific oils chemically activate your pain receptors (TRPV1).
• The Smoke Point Lie: Why "high smoke point" oils can still rot your DNA.
• The Official Protocol: My Tier 1, 2, and 3 hierarchy for the longevity-focused kitchen.
