What are LDL and HDL?

• LDL stands for low-density lipoproteins. These
  are often referred to as bad cholesterol.
• Low density lipoproteins don't move around the
  bloodstream very well. They tend to get "left
  behind" and can clog up the arteries. Such
  clogging can contribute to atherosclerosis. If a
  blood clot occurs in a blocked region then it can
  result in heart attack and/or stroke.
• HDL stands for high-density lipoproteins. These
  are often referred to as good cholesterol.
• Unlike LDLs, HDLs can be carried around the
  bloodstream much more easily. As such they don't
  contribute to dangerous hardening of the
  arteries. In fact many experts believe that HDL
  cholestrol can actually help to remove LDLs and
  other substances that are blocking the arteries.
