In this eye-opening second installment of our series on cardiovascular disease, Dr. Ravi Kumar dives deep into the forgotten history and modern science behind one of the most controversial components of our diet: seed oils.  We’ll explore how linoleic acid—the dominant fat in seed oils—became a staple in the modern food supply, why its structure makes it chemically fragile and pro-inflammatory, and how its oxidation within LDL particles may be the real spark that ignites atherosclerosis.  You’ll learn: Why the diet-heart hypothesis linking saturated fat to heart disease falls apart under scrutinyThe disturbing truth behind how seed oils are chemically extracted using hexaneHow linoleic acid disrupts the body’s inflammatory balance and contributes to chronic diseaseWhy LDL isn’t the villain—but what’s inside LDL particles might beThe striking findings from forgotten studies like the Sydney Diet Heart Study, the Minnesota Coronary Experiment, and Dr. Malhotra’s Indian railway worker researchPractical steps to reduce seed oil intake and rebalance your omega-6 to omega-3 ratioIf you’ve ever wondered why heart disease remains the world’s #1 killer despite decades of low-fat advice, this episode will challenge what you think you know—and offer a clearer path forward.References:Seven Countries Study – Ancel Keys et al.
