Calories in Nuts, macadamia nuts

What makes nuts so powerful?

Macadamia nuts are native to the eastern coast of Australia and were a prized food source for Aboriginal Australians for thousands of years before commercial cultivation began. The nuts grow on trees belonging to the genus Macadamia, and only two of the four species produce edible nuts, as the other two contain toxic cyanogenic glycosides. From a biochemical perspective, macadamias boast the highest fat content of any commercial nut, yet over half of this fat is monounsaturated, specifically oleic acid, the same heart-healthy fat found in olive oil. They also uniquely contain significant amounts of palmitoleic acid, a rare omega-7 fatty acid rarely found in plant foods, which is studied for its potential role in regulating insulin sensitivity and reducing inflammation. The extreme hardness of the macadamia shell requires industrial-grade cracking equipment; applying roughly 300 pounds of pressure per square inch to break without fracturing the delicate kernel inside. This mechanical difficulty, combined with their slow tree maturation, explains why macadamia nuts remain among the most expensive nuts globally.
