Feh. LDL gets a misunderstood rap. The liver only dumps it in the first place in response to arterial damaging agents that we consume on a daily basis. Avoid consuming Chlorine, hydrogenated oils and homogenized milk as much as possible and you will be fine, regardless of how much normal fats you eat.
In the “Black” spinoff, LDL agents are depicted as illegally burying cholesterol in the tunnel floors. The way I would depict it, would be a molecule of hydrogenated fat or homogenized lactose would be bouncing around like a piece of Flubber, only with sharp spikes sticking out, scratching and denting the tunnels here and there at random, as well as occasionally injuring a red cell. LDL agents would then show up to patch the damage with some cholesterol, like cement for a pothole, but when SWARMS of the damn things are ricocheting all over the place day after day they get overwhelmed, and patch too much. Chlorine doesn’t bounce, but damages the wall once per atom by stealing a sodium ion, becoming then after harmless salt, so it’s more like a bullets or shrapnel being fired into the walls. Same basic damage either way.
