Danielle Belardo has built a reputation on one impolite question: where is the evidence? A preventive cardiologist who treats the disease that kills more Americans than any other, she joined Sean Kelly on the Digital Social Hour to sort out what actually protects the heart — and which wellness trends are simply expensive noise.
Across nearly an hour, Dr. Belardo runs the internet's favorite health claims — carnivore diets, fish oil pills, parasite cleanses, detoxes, intermittent fasting — through the filter of published research, and shows how anyone can learn to tell a real study from lab-coat marketing.
About Danielle Belardo
Dr. Danielle Belardo is a preventive cardiologist and the founder of Precision Preventive Cardiology, a practice devoted to stopping heart disease before it starts. She has become one of medicine's most visible advocates for evidence-based care, known for separating sound science from supplement marketing.
That advocacy extends well beyond the clinic. Through her podcast Wellness: Fact vs. Fiction and a substantial social media presence, Belardo has challenged health misinformation while making the fundamentals — LDL and ApoB, a plant-predominant Mediterranean diet, statins for those who truly need them — genuinely understandable.

Why This Conversation Matters
Health misinformation travels faster than peer review, and most people have no referee for the claims filling their feeds. Danielle Belardo provides one: a working cardiologist's framework for deciding what deserves your trust, your money, and your arteries. It is one of the most practically useful hours the show has aired.
