Yeah, I know that the effect is minor, but the same foods that have a lot of cholesterol, also tend to have a lot of fats and whatnot, so it's not a bad idea to moderate.
Eating fats doesn't raise your blood cholesterol level either. Diet is complicated, but all these myths about cholesterol/fat in leading to blood cholesterol have been debunked. People who avoid eating them tend to eat a lot more carbs and end up with higher cholesterol.
I’ve heard of a connection between carb intake and triglycerides, but this is the first I’ve heard about there being a connection to cholesterol levels.
