HDL is pretty much the general opposite of all other answer options. HDL Cholesterol or High Density Lipoproteins, is considered a "Good" cholesterol. These cholesterol are, just as they are named, Dense. This density means that you have more calorie rich cholesterol packed into smaller bits. This reduces the chance of plague buildup and clots.
