Fat = Cholesterol.

Cholesterol in your food is not the biggest culprit for raising your blood cholesterol level. Saturated fat (red meat and whole dairy) and trans fats (fast foods and processed foods) are the primary dietary contributors to high cholesterol. Egg yolks, for example, may have lots of cholesterol, but are considered unlikely to raise your cholesterol level if eaten in moderation as part of a diet low in saturated fat. High-fiber foods, such as oats and beans, help diminish "bad" cholesterol levels, as will regular moderate physical activity.
