I have tons of personal notes on this but nothing in a shareable state, so please excuse me getting an AI to give you an answer: https://www.perplexity.ai/search/explain-how-ldl-particle-size-3Zh8olsJQ2SUj91OoirKGA#0

Basic idea is: total cholesterol count is worse than irrelevant. LDL comes in various particle sizes: small dangerous, large okay. Other metabolic and diet factors are more predictive of cardiovascular health.

Add to that: dietary cholesterol (cholesterol on the label of what you're eating) has little to no impact on heart health either.
