Lowering Cholesterol Killed: A Study Buried for 40 Years

In this video, I break down a forgotten ‘gold-standard’ randomized controlled trial from the late 1960s and early 1970s: the Minnesota Coronary Experiment. This uniquely rigorous study tested whether replacing saturated fat (butter, beef) with vegetable oils rich in linoleic acid would reduce heart disease and mortality. The results were shocking. Cholesterol dropped—but deaths increased. Even more unsettling, the greater the cholesterol reduction, the higher the risk of death. Cardiovascular outcomes didn’t improve either. The cholesterol reducing diet was even associated with a trend towards increased atherosclerosis on autopsy. So why were these results buried for decades? Were they inconvenient? Misunderstood? Or simply too complex for a simple narrative? We’ll walk through the study design, the actual outcomes, and the major criticisms—then evaluate whether those critiques really hold up.
