Monounsaturated and polyunsaturated fats are considered beneficial for heart health. These types of healthy fats can help improve cholesterol levels by reducing low-density lipoprotein (LDL) or "bad" cholesterol while increasing high-density lipoprotein (HDL) or "good" cholesterol. Foods rich in these fats include olive oil, avocados, and fatty fish. They provide essential fatty acids that support cellular function and reduce inflammation. Incorporating these fats into the diet can lower the risk of cardiovascular disease and improve overall heart health.
