Monounsaturated fats are a type of healthy fat found in foods like olive oil, avocados, and nuts. They can help reduce bad cholesterol levels in the blood, which may lower the risk of heart disease. These fats are typically liquid at room temperature and are considered beneficial for overall health. Polyunsaturated fats include omega-3 and omega-6 fatty acids, which are essential for the body. Sources of polyunsaturated fats include fatty fish, flaxseeds, and walnuts. Like monounsaturated fats, they can also improve heart health and support brain function, making them an important part of a balanced diet.
