Macadamia nuts are a type of nut with a subtle, butter-like flavor and creamy texture. This nut oil, known as macadamia oil or macadamia nut oil, is produced by extracting oil from the fruit or walnut of the Australian Macadamia integrifolia tree. Apart from its use in cooking, many people use this oil to treat hair and improve skin health. The oil provides some health and beauty benefits, but not all of them are backed by strong scientific evidence.
Macadamia oil contains a high concentration of palmitoleic acid, which is rich in omega 7. Macadamia nuts are native to Australia, also grown in the temperate climates of California and Hawaii. These nuts have high content of zinc, selenium and fatty acids that help the body burn fat more effectively. Other common names are Queensland hazelnuts, Maroochi hazelnuts, Bush hazelnuts, Hawaiian hazelnuts, Bauple hazelnuts, Australian peanuts, Smooth-shelled Macadamia, Bush nut, Bopple Nut, Poppel Nut, Huile de Macadamia, Macadamia Oil, Macadamia integrifolia, Macadamia tetraphylla.
Fats in Macadamia Oil
Macadamia nut oil contains different types of fat, including saturated fat, polyunsaturated fat and monounsaturated fat. More specifically, the compounds contained in the oil are as follows:
- Oleic acid (about 55-67 percent): Oleic acid is a monounsaturated fat that can improve cardiovascular health when used in place of saturated fats or refined carbohydrates.
- Palmitoleic acid (about 18-25 percent): A monounsaturated fatty acid that may have beneficial effects on insulin sensitivity, cholesterol metabolism.
- Palmitic acid (about 7-9 percent): A saturated fatty acid that can increase LDL cholesterol and negatively affect heart health.
- Stearic acid (about 2-5 percent): It is a saturated fatty acid that can lower LDL cholesterol and is not as effective as unsaturated fats.
- Linoleic acid (about 1-4 percent) or omega-6 fatty acids: These polyunsaturated fats are sometimes associated with weight loss, but evidence is lacking.
Most of the fat in macadamia oil is monounsaturated fat, according to USDA data. The expert at the Academy of Nutrition and Dietetics recommends choosing foods containing monounsaturated fat instead of saturated fat whenever possible and consuming 15-20 percent of the calorie intake from monounsaturated fat. In addition, some polyunsaturated fat is consumed with this nut oil consumption. Studies have shown that these essential fatty acids can help lower LDL (bad) cholesterol and prevent cardiovascular disease. Nutritionists recommend that 3-10 percent of daily calorie intake be taken from polyunsaturated fat.
The saturated fat in macadamia nut oil (stearic acid) may have a beneficial effect on heart health, but in general, health experts recommend reducing saturated fat intake, instead consuming mono and polyunsaturated fats. Also, this fat has no carbohydrates or proteins.
