No, butter does contain monounsaturated fats, but it is not considered a primary source. This is because the predominant type of fat in butter is saturated fat.
An average pat of butter, weighing about 14 grams, contains nearly 3 grams of monounsaturated fat. However, it also contains around 7 grams of saturated fat. Hence, while butter does contain monounsaturated fats, its higher saturated fat content necessitates moderate consumption.
