How are macadamia nuts beneficial for my health?

The health benefits of macadamia nuts are similar to those of other nuts that provide a high content of monounsaturated fat and arginine. Several studies conducted at the University of Hawaii have shown significant health benefits of macadamia nuts. For example, the latest study was conducted to assess the cholesterol-lowering potential of macadamia nuts. 17 men with elevated cholesterol levels were given macadamia nuts (40 to 90 g per day), equivalent to 15 percent energy intake, for four weeks. At the end of four weeks, their plasma total cholesterol and LDL cholesterol concentrations had decreased by 3.0 and 5.3 percent, respectively, and their HDL cholesterol levels had increased by 7.9 percent.

Macadamia nut oil also provides significant health benefits. While olive oil and canola oil are by far the most popular monounsaturated fats in use, macadamia nut oil is superior to cook with because of its lower level of polyunsaturated fat (3 percent for macadamia nut oil, versus 8 percent for olive oil, and 23 percent for canola oil). As a result, while olive oil and canola oil can form lipid peroxides at relatively low cooking temperatures, macadamia nut oil is stable at much higher temperatures (over twice more stable than olive oil and four times more stable than canola). Macadamia oil, like olive oil, is also very high in natural antioxidants. In fact, it contains more than 4.5 times the amount of vitamin E as olive oil.
