1) Low-density lipoprotein (LDL): LDL, or ‘bad’ cholesterol, will increase the build-up of fats in the arteries, and may cause the arteries to be clogged.
2) High-density lipoprotein (HDL): HDL, or ‘good’ cholesterol, removes cholesterol from the cells before they are deposited as plaque in the arteries, thus preventing the build-up of fats in the arteries.
