The type of fat considered heart-healthy and beneficial in moderation is monounsaturated fat. Common sources include olive oil, avocados, and nuts. These fats can help lower bad cholesterol levels (LDL) while increasing good cholesterol (HDL), promoting cardiovascular health. Furthermore, they possess anti-inflammatory properties and support overall well-being. Including monounsaturated fats in a balanced diet can aid in nutrient absorption and contribute to heart health. However, it is essential to consume them in moderation, as all fats are calorie-dense and excessive intake can lead to weight gain.
