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.
Polyunsaturated fats are also thought to help lower total and bad cholesterol. But monounsaturated fats tend to be favored over polyunsaturated fats because some research suggests that polyunsaturated fats are less stable, and can reduce levels of good cholesterol as well as bad.
