Unsaturated fats, such as those found in olive oil, avocados, and nuts, are considered healthy and beneficial for heart health. These fats help lower bad cholesterol levels (LDL) while raising good cholesterol (HDL), contributing to improved overall cardiovascular health. They also provide essential fatty acids needed for various bodily functions and promote nutrient absorption. Incorporating sources of unsaturated fats into a balanced diet can enhance heart health and lower the risk of heart disease.
