About 20% of your cholesterol comes from your diet, the other 80% is made by the liver and intestines. Genetics play heavily on your cholesterol numbers. I think Ticka's point is many people have a misconception that diet has a larger contribution to the cholesterol numbers. If that were true compliant patient would not have the need for statins or other cholesterol medications. Your primary physician and/or cardiologist will still recommend a healthy diet and exercise to achieve or maintain a healthy body weight plus other metabolic benefits.

If you are interested in the biological processes behind cholesterol production, a quick google search will quench your thirst, just pick reliable sources.
