LDL cholesterol is part of what causes heart disease, but that doesn't mean high cholesterol alone causes it or that everyone with high LDL needs treatment. The confusion is treating causality as sufficiency.
What's the biggest misconception people have about cholesterol and LDL? I think it's the confusion between the ideas of causality and importance.
So one area of, I would say, debate is whether or not LDL cholesterol is quote-unquote, heavy quotes, causal in cardiovascular disease. And I just see like, you know, bickering on social media, people saying it is causal, isn't causal, without really understanding what that word means. The word by definition means it's part of a causal cascade. It's involved in the chain, but that doesn't mean it alone is sufficient to cause disease, and really importantly, it doesn't mean that you need to treat high cholesterol in all cases.
