  • Episode 3: Is High LDL Really the Culprit? (Cardiovascular Disease Part 3)

    Episode 3: Is High LDL Really the Culprit? (Cardiovascular Disease Part 3)
    May 9 2025
    In this episode of the Dr. Kumar Discovery Podcast, we dive deep into one of the most controversial questions in cardiology: Does high LDL cholesterol actually cause heart disease? We explore the historical origins of the cholesterol hypothesis, unpack evidence from traditional societies and modern studies, and challenge the “lower is better” narrative. You’ll learn how cholesterol functions in the body, why LDL may not be the villain it’s made out to be, and when lowering it actually makes sense. We cover: The story of President Roosevelt and how his death led to the Framingham Heart StudyWhat traditional cultures like the Tsimane, Maasai, and Inuit reveal about “normal” cholesterolWhy very low LDL is associated with higher all-cause mortalityWhat CAC scans tell us about real cardiovascular riskThe Injury Response Hypothesis — a new way to view atherosclerosisWhether statins make sense in every case — and how to personalize your approachWhether you’re taking a statin, being told to start one, or just want a deeper understanding of cholesterol and cardiovascular risk, this episode offers a balanced, evidence-based perspective that cuts through the noise. References & Key Studies 1. The Origins of Cholesterol GuidelinesThe Framingham Heart StudyNIH Open AccessA landmark cohort study launched in 1948 to uncover causes of cardiovascular disease. It helped establish cholesterol, smoking, and blood pressure as key risk factors. 2.

  • Episode 2: The Seed Oil Problem — How Linoleic Acid Fuels Heart Disease (Cardiovascular Disease Part 2)

    Episode 2: The Seed Oil Problem — How Linoleic Acid Fuels Heart Disease (Cardiovascular Disease Part 2)
    May 3 2025

    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 scrutiny
    • The disturbing truth behind how seed oils are chemically extracted using hexane
    • How linoleic acid disrupts the body’s inflammatory balance and contributes to chronic disease
    • Why LDL isn’t the villain—but what’s inside LDL particles might be
    • The striking findings from forgotten studies like the Sydney Diet Heart Study, the Minnesota Coronary Experiment, and Dr. Malhotra’s Indian railway worker research
    • Practical steps to reduce seed oil intake and rebalance your omega-6 to omega-3 ratio

    If 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.

  • Cardiovascular Disease Part 1: Is Saturated Fat Really the Villain?

    Cardiovascular Disease Part 1: Is Saturated Fat Really the Villain?
    Apr 26 2025


    Cardiovascular Disease Part 1: Is Saturated Fat Really the Villain?

    Description:

    In this first full episode of The Dr Kumar Discovery, we kick off a multi-part series on cardiovascular disease — a condition that touches nearly every family.


    Today, we take a critical look at the long-standing belief that saturated fat is the primary driver of heart disease.

    Where did this idea come from? How strong is the evidence? And have we overlooked something important along the way?

    From the early cholesterol discoveries to the Seven Countries Study, to forgotten randomized controlled trials like the Sydney Diet Heart Study and the Minnesota Coronary Experiment, we dig into the real story behind the diet-heart hypothesis — and why it’s time to rethink what we’ve been told about saturated fat and heart health.

    In this episode, you’ll learn:


    • Why cholesterol is essential to life — not a villain
    • How cholesterol travels in your body and why LDL isn’t “bad”
    • The origins of the diet-heart hypothesis
    • How early observational studies shaped decades of nutrition policy
    • Why correlation doesn’t mean causation — and why that matters
    • What major randomized controlled trials really showed about saturated fat
    • The role of trans fats and industrial oils in heart disease
    • What we can learn from traditional cultures like the Tokelauans
    • Why saturated fat was likely scapegoated — and what we should really be focusing on


    If you’ve ever questioned the mainstream advice on diet and heart health — or if you just want to understand your body and your health better — this episode is for you.
