Episode Summary

Why is vitamin C—a nutrient most people take for granted—still at the center of scientific debate and miraculous recoveries? In “The Vitamin C Paradox,” Dr. Ravi Kumar explores the hidden complexity behind this essential molecule, from our evolutionary dependence to it...

Episode Summary 

In this deep-dive episode, Dr. Ravi Kumar explores why omega-3 fatty acids are foundational to human health—touching on their biochemistry, evolutionary history, robust clinical evidence, and practical strategies for optimizing intake. You’ll learn: 

What “omega-3” really means and why your body can’t make these fats on its ownEarly discoveries by George and Mildred Burr in the 1920sThe Inuit paradox: high-fat diets with low cardiovascular diseaseLandmark trials such as REDUCE-IT and EVAPORATE demonstrating cardioprotective effectsRoles across the lifespan: brain development, mood regulation, eye health, immune function, muscle maintenance, liver health, skin integrity, and moreEvol...

 Episode 7: Why You Should Be Taking Vitamin K2 

 

Host: Dr. Ravi Kumar MD

Topic: A comprehensive look at vitamin K2’s discovery, mechanisms, clinical evidence, and why it’s essential for calcium homeostasis, bone strength, and vascular health. 

 

📖 Episode Overview 

Historical journey from Weston A. Price’s “Activator X” to the Nobel‐winning discovery of vitamin KBiochemical roles of K1 vs. K2: activating clotting factors vs. directing calcium into bones and out of arteriesAncestral dietary patterns that once guaranteed year-round vitamin K2 intakeKey clinical findings on bone mineral density, fracture ris...

 In this episode, Dr. Ravi Kumar uncovers the powerful, misunderstood role of vitamin D in your health—and why nearly half the world is deficient. Far more than a bone vitamin, vitamin D acts as a hormone that regulates over 1,000 genes and plays a role in everything from immune function and mood to metabolism, muscle strength, and even cancer prevention. 

 

Dr. Kumar shares stories from his family, travels, and medical practice—including a powerful transformation in his grandmother’s health—to reveal the often-overlooked symptoms of deficiency and how to fix them. You’ll learn about testing...

 Episode 5: The Untold Power of Diet and Lifestyle (Cardiovascular Disease: Part 5) 

 
In this episode, we uncover why real-world interventions—whole-food diets, metabolic health markers, and the simplest “medicine” of all—walking—outperform any pill in preventing and reversing heart disease. 

 

Topics include 

Ancestral lessons from the Mediterranean, Panama, Japan, and the Nordic countriesKey RCTs: Lyon Diet Heart, PREDIMED, CORDIOPREVMechanisms: refined carbs & seed oils driving insulin resistance and endocannabinoid activationVisceral fat & hormones: aromatization of testosterone, GLUT4 dysfunctionAtherogenic cascade: ↑VLDL → CETP exchange → small dense, oxidized LDL → plaque formationDysfunctional HDL and breakdown of reverse cholesterol transportTri...

 Episode 4: Should You Take a Statin? (Cardiovascular Series: Part 4)

 

In this episode, we dive deep into statins—the most widely prescribed cholesterol-lowering drugs—and ask the hard questions: 

Do they really prevent heart disease? Are the benefits worth the risks? What does the data really say? 

 

Topics include: 

The history of statins and how they were discoveredThe role of LDL in healing vs. harmRisks: muscle pain, cognitive issues, diabetes, mitochondrial dysfunction, and moreBenefit vs. risk by ASCVD scoreMajor trials like JUPITER, FOURIER, and the CTT meta-analysisThe role of PCSK9 inhi...

In this episode of the Dr. Kumar Discovery Podcast, we dive deep into one of the most controversial questions in human health: 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 d...

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...

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 Co...
