Dr. Rachel Marynowski shared a perspective on cholesterol history that makes you pause. In the 1970s, doctors weren’t aggressively screening for high cholesterol because levels up to around 300 mg/dL were often still considered within a normal range. Cholesterol is something the body produces and needs for many essential... functions, including cell membranes and hormone production. Then in 1984, the National Institutes of Health launched the National Cholesterol Education Program. This coincided with pharmaceutical companies developing the first statin drugs (the first one, lovastatin, was approved in 1987). Over time, guidelines from groups like the American Heart Association and American College of Cardiology lowered the thresholds for what was considered “high” cholesterol. The result? Millions more people became candidates for cholesterol-lowering medication. Dr. Marynowski, an integrative physician, points out that this shift happened alongside heavy pharmaceutical involvement in research, education, and guideline development — raising questions about how much science versus commercial interests shaped the narrative that cholesterol is primarily a villain. Science nugget: Cholesterol is vital for human physiology. The body synthesizes most of what it needs (about 75–80% in the liver), and it plays critical roles in producing steroid hormones (like cortisol, estrogen, and testosterone), vitamin D, and bile acids for digestion. Extremely low cholesterol levels have been associated in some studies with higher risks of certain health issues, though optimal ranges remain debated. It’s a reminder that medical guidelines and “standard care” can evolve — sometimes influenced by more than just pure science. What are your thoughts on how cholesterol guidelines have changed over the decades, or how much weight you give to the role of pharmaceutical funding in shaping them?show more
