God fat-bad fat, good cholesterol-bad cholesterol

Question
Hi a friend of mine told me that if I eat low/good cholestral butter or magarine this will help get rid of any bad cholestral I eat?

Is this true in other words should I eat lots of it or is it better not to have it at all.

The thing I was wondering is, apart from we need a certain amount of fat in our diets, does this good cholestral combine with bad cholestral to get rid of it or is it still bad for you, just not as bad as the saturated fats?

Many thanks indeed

Steve

Answer
Steve, first of all, here are some definitions:

LDL, or low-density lipoprotein, is "bad" cholesterol. LPL levels should be below 160.

HDL, or high-density lipoprotein, is "good " cholesterol. HDL levels should be above 45.
