To reduce fats, health experts recommend an eating pattern rich in a variety of grains, fruits and vegetables. Lean meats, poultry and fish, lowfat dairy products and fats and oils found in margarine products, butter, oil and salad dressings should be used in moderation. As one step to help reduce saturated fat intake, the American Heart Association recommends soft margarine and spreads instead of butter and other solid fats. The type and amount of dietary fats may affect levels of blood cholesterol. High blood cholesterol levels are one risk factor for coronary heart disease.
Studies show some saturated fats raise blood cholesterol levels and unsaturated fats lower levels.
Saturated fats are typically found in higher amounts in meats, egg yolks, whole milk and milk products. Unsaturated fats are found in higher amounts in nuts and liquid vegetable oils. More research is needed to determine the overall impact of trans fats on heart disease risk. Most nutritionists agree, however, that the most important priority for Americans is to reduce saturated and total fat in the diet, especially if you are at high risk of heart disease. Cholesterol is a part of all body cells and plays key roles in the formation of brain and nerve tissues and some hormones.
