The types of potentially helpful dietary fat are mostly unsaturated: Monounsaturated fatty acids. This is a type of fat found in a variety of foods and oils. Studies show that eating foods rich in monounsaturated fatty acids improves blood cholesterol levels, which can decrease your risk of heart disease.
To improve your cholesterol levels, avoid or limit food sources of cholesterol and saturated and trans fat while choosing food containing fiber and unsaturated fats. Only animal foods contain bad fats and cholesterol; plant foods and most fish do not. The Academy of Nutrition and Dietetics recommends eating 20 to 35 percent of your daily calories from mainly unsaturated fat while limiting saturated fat and avoiding trans fat altogether.
