Yes, there are two types of LDL cholesterol: the small, dense kind and the large, fluffy kind. The small, dense ones are the troublemakers because they’re more likely to sneak into artery walls, get oxidised, and cause plaque buildup, which can lead to heart problems. On the other hand, the big, fluffy LDL particles are pretty harmless and don’t cause much trouble. The issue is that high blood sugar can damage LDL particles through a process called glycation, making them smaller and denser—and that’s when they become a problem. So the key is to keep you blood sugar levels low.
