Keeping a healthy cholesterol level


How does a healthy cholesterol level help prevent a stroke?

There are 3 main types of fat in blood:

  • Low density lipoprotein (LDL). Often called “bad cholesterol”.  LDL sticks to the walls of your blood vessels making it harder for blood to flow through
  • High-density lipoprotein (HDL). Often called “good cholesterol”. HDL helps carry bad cholesterol away from the arteries making it easier for blood to flow through them. 
  • Triglycerides are another type of blood fat used in the body for energy. Too much will increase your chance of heart disease and stroke.
