Health & Nutrition

We all love that soft crunch and buttery flavour of macadamias, but did you know that macadamias also provide a range of health benefits? When a healthy handful of macadamias (30g) is consumed each day as part of a healthy diet, it may lower your risk of heart disease, type 2 diabetes, oxidative stress and can assist in weight management.

Rather than write heaps about how great macadamias are, we thought we just give you a taste of some of the great reasons why macadamias are good for you to eat!! And we know that there are other people who know more about the health benefits than us so a bit further down the page we have some links to good, credible sources of information about macadamias.

 

Macadamias and Health

Research has shown that eating macadamias can reduce heart disease risk. Macadamias have the highest percentage of monounsaturated fats of any tree nuts and also contain antioxidants in the form of Omega 3 that are noted to be beneficial to health. As with all tree nuts they contain no cholesterol.

Contrary to popular belief consumption of tree nuts is not fattening. Although macadamias are high in fat, research work has shown that eating nuts does not lead to weight gain. In fact nuts may help with managing weight.

A handful of macadamias contains around 30% of your daily requirements of thiamin – also known as B1. B1 is vital for turning food into energy.

Macadamias are rich in manganese – a mineral that is essential in bone formation and the breakdown of carbohydrate, cholesterol and amino acids. A handful of macadamias provides nearly 25% of RDI for manganese.

Did you know that a handful of macadamias contains about the the same amount of fibre as a slice of wholegrain bread? A high fibre diet is necessary for maintaining healthy bowel function.

Raw macadamias have been awarded a 5 star rating – the highest possible under the Australian Governments Health Star Rating System (www.healthstarrating.gov.au). The Health Star Rating is a front-of-pack labelling system that rates the overall nutritional profile of packaged food and assigns it a rating from ½ a star to 5 stars. The more stars, the healthier the choice.

Eating nuts and better health

Macadamia Kernels

Australian macadamia kernel is high in nutritional value. The natural oil content is primarily mono-unsaturated, which makes macadamias a favoured food with dieticians. More importantly, macadamias contain no cholesterol: a significant benefit to persons at risk of heart disease.

Macadamia Oil – The “No Cholesteroil”

Australian Macadamia Oil is a high quality, 100% PURE Virgin Oil obtained from the kernel of the world’s most delicious nuts, grown and processed in their native area of Northern New South Wales and Southern Queensland.

Through the cold pressing process Australian Macadamia Oil retains its unique flavour and aroma making it an ideal ingredient for salad dressings and sautéed foods. Because it is 85% monounsaturated and contains NO CHOLESTEROL it is a healthy alternative to other cooking oils.

Australian Macadamia Oil also contains high levels of palmitoleic acid and it has been pharmaceutically approved for use in cosmetics and skin preparations.

Macadamia Oil has a higher smoke point than olive oil, making it prized by many chefs.
