Cooking Advantage: Although this isn’t a definitive health benefit, macadamia nut oil has a higher smoke point than other vegetable oils, like olive oil. Therefore, when you’re cooking with macadamia nut oil, you are far less likely to burn off the beneficial fats, which are the main reason why you are using the oil in the first place. This will also help to retain the flavor of the oil, which is pleasant and beneficial to many meals, particularly when used as a salad oil.
