The Cholesterol Code follows Dave Feldman's own health journey into a question mainstream cardiology thought was settled: what cholesterol numbers actually mean for heart risk. The 2026 documentary is now streaming on K-Time with Persian dubbing and subtitles.
What is The Cholesterol Code about?
Millions of Americans take statins as a matter of course, and The Cholesterol Code starts from that fact before turning it into a question. Dave Feldman's personal experiment with a ketogenic diet produces cholesterol readings that do not fit the standard model, and the documentary uses that anomaly to pull in cardiologists, researchers and metabolic-health specialists who have been arguing about lipid science for years. Rather than delivering a single verdict, the film lays out competing interpretations of the same data and lets viewers see where the disagreement actually sits, from statin guidelines to how a high-fat diet interacts with blood markers doctors have relied on for decades.
About the cast
Dave Feldman anchors the documentary as its central case study, with physicians and researchers including Bret Scher, Arthur Agatston, Matthew Budoff, Nick Norwitz, Gary Taubes, Georgia Ede and Dr. Shawn Baker appearing to give the science its competing sides. Jennifer Isenhart directs, assembling interview and explanatory material rather than a single narrator's argument.
Context & significance
The Cholesterol Code sits alongside a growing run of nutrition-science documentaries built around a single patient's data rather than a general health survey, which lets it go deeper into one specific and contested question instead of covering the field broadly. At 106 minutes, it has room to let each expert make a full case rather than reducing the debate to soundbites.
