Except that when you eat cholesterol, it is digested and absorbed from the food as cholesterol, not lipoproteins. So it's really silly to say there's "bad" or "good" cholesterol in food. The main purpose of lipoproteins such as LDL and HDL is to carry fatty fuel around the body. Cholesterol just gets a ride-share along with the fat since it is not water (and by extension blood) soluble. And the thing that makes levels of HDL and LDL in the blood "bad" has more to do with high blood sugar messing up the lipoproteins' ability to identify itself to the liver (search oxidation & glycation of lipoproteins) which causes excess levels in the blood, than it has to do with cholesterol. IMO the focus on cholesterol (edit: as the source of disease) in popular science and medicine has been a huge mistake.
