Chicken eggs are high in cholesterol. And a high-cholesterol diet contributes to high blood cholesterol levels. However, how much the cholesterol in your diet can increase your blood cholesterol varies from person to person. Although eating too many eggs can increase your cholesterol, eating four egg yolks or fewer on a weekly basis hasn't been found to increase your risk of heart disease. If you like eggs but don't want the extra cholesterol, use egg whites, which don't have cholesterol. Or use cholesterol-free egg substitutes, which are made with egg whites. If you want to reduce cholesterol in a recipe that calls for eggs, use two egg whites or 1/4 cup cholesterol-free egg substitute instead of one whole egg.
