The type of fat considered the "heart-healthy" fat is monounsaturated fat. Found in foods like olive oil, avocados, and nuts, monounsaturated fats can help reduce bad cholesterol levels in the blood, potentially lowering the risk of heart disease. In contrast, trans fats and saturated fats can contribute to cardiovascular issues. Incorporating healthy fats into the diet not only benefits heart health but also provides essential fatty acids and promotes satiety, making it a crucial aspect of a balanced diet.
