Dietary cholesterol actually has very little to do with body cholesterol levels. Even if you ate an extremely high cholesterol diet, your body would still produce 80% of the cholesterol it needs. The amount of cholesterol you eat each day only contributes to a small amount of the cholesterol your body needs each day. The vast majority of cholesterol in the body is produced by the body itself.
Poor cholesterol levels are due to a diet high in refined carbohydrates, sugar, and trans fats.
The best thing you can do to improve cholesterol levels is to eat a cholesterol friendly diet - high in omega 3 fatty acids, fruits and vegetables.
