Macadamia nuts are packed with phytochemicals; compounds found in plants that show anti-inflammatory and antioxidant behaviour^{3,16,36,37,38}. Oxidative stress is caused by harmful free radicals that form in the body due to the numerous chemical reactions occurring³⁹. This cell damage contributes to inflammation, premature ageing and chronic diseases like heart disease, type 2 diabetes and dementia⁴⁰. Studies show that eating naturally antioxidant-rich nuts, such as macadamias, as part of a diet rich in fruits, vegetables, legumes and whole grains, improves markers of oxidative stress therefore reducing the risk of chronic disease and premature ageing^41,42. Macadamias also contain antioxidant minerals, such as manganese, magnesium and copper, which play an important role keeping us and our immune systems healthy. They are a source of tocotrienols too, a form of vitamin E with antioxidant properties, that may help lower cholesterol and protect against certain cancers and brain diseases⁴³.
