Two types of cholesterol

Cholesterol is a white and waxy substance. There are two types of cholesterol:
Low density lipoprotein (LDL) cholesterol – called the ‘bad’ cholesterol because it goes into the bloodstream and clogs up your arteries. High density lipoprotein (HDL) cholesterol – called the ‘good’ cholesterol because it helps to take the ‘bad’ cholesterol out of the bloodstream.
