The type of dietary fat considered healthy is monounsaturated fat, found in foods like avocados and olive oil. These fats can improve heart health by lowering bad cholesterol levels while raising good cholesterol levels (HDL). Additionally, monounsaturated fats may provide anti-inflammatory benefits and are associated with a reduced risk of chronic diseases. Incorporating these healthy fats into the diet supports overall well-being and contributes to a balanced nutritional profile.
