Why do some sources say macadamia nut oil is one of the healthiest oils?
The nutrition benefits of macadamia oil stem from the type of fat it contains. It is mostly monounsaturated fat, which does not raise blood cholesterol and does not seem to promote inflammation. From a cooking perspective, it has a high smoke point, meaning it can be used in high-temperature stir-frying or sautéing without smoking. However, macadamia nut oil can be difficult to find in stores in some locations and is often rather expensive. Macadamia nut oil is a healthy choice, but other oils with mostly monounsaturated fat and smoke points as high or higher include not only the equally expensive almond and avocado oils, but also the more reasonably priced peanut and pure or extra light (not extra virgin) olive oils. Calorie content of all these oils is the same, so enjoy the flavor they add to food, but don’t overdo.
