The recommended type of fat for heart-healthy cooking is unsaturated fats, which include both monounsaturated and polyunsaturated fats. These fats can improve cholesterol levels by reducing low-density lipoprotein (LDL) cholesterol, commonly known as "bad" cholesterol. Sources of unsaturated fats include olive oil, avocados, nuts, and fatty fish rich in omega-3 fatty acids. In contrast, saturated and trans fats should be limited, as they can increase cardiovascular disease risk. Incorporating healthy fats into one’s diet can support overall heart health and enhance the flavor of meals, making them more enjoyable.
