It’s Macadamia Day!

Our friends at Brookfarm are a leading Australian gourmet food producer committed to sustainable agriculture and premium food production. “It starts on the family farm” with their prized macadamias, Australia’s indigenous nut. Their passion is to produce the highest quality real food and to make a difference to the community and environment.

Native to Australia, the macadamia tree is an Indigenous Australian rainforest tree which grows along the eastern coast of New South Wales and Queensland. Approximately 60 million years ago the first macadamia tree evolved in the north east coast. From Port Macquarie to the Atherton Tablelands in the north, half the crop is grown in New South Wales and the other half in Queensland.

Due to the sub-tropical climate they provide optimum growing conditions for the trees, with ideal growth happening between 20-25 degrees Celsius. The macadamia trees can grow as high as 12 to 15 metres and can take 10 to 15 years before they reach their full growth and harvest potential.

Whilst Australia contributes to over 30% of the global crop, macadamia trees can also be found growing in Kenya, Guatemala, Hawaii and South Africa. According to French culinary chef Bertrand Simon, the macadamia nuts high fat content brings out other flavours extraordinary well, permitting them to be a very versatile ingredient in cooking.

A serving of macadamia nuts is 30g which is comparable to 15 nuts. They’re very nutritious; providing an abundance of vitamins, minerals and antioxidants which are beneficial to overall health. Macadamias are a source of dietary fibre and protein, they contain good amounts of monounsaturated and polyunsaturated fats and are low in glycaemic index, sugar and sodium. Furthermore, they contain the antioxidant minerals manganese, magnesium and copper.

Fast fact: Macadamias freeze very well! So well, they can last for around six months in a sealed bag or container.

Additionally, they show an association with the following health benefits.

• Macadamias are a high source of monounsaturated fats and contain polyphenol compounds. Research suggests regular consumption of macadamia nuts reduces oxidative stress and inflammation, thus preventing risk of heart disease (Manohar et al. 2007)
• Full of phytochemicals which have anti-inflammatory and antioxidant properties. The antioxidants work by reutilizing free radicals caused by oxidative stress, reducing cell damage whilst improving cognitive function and overall aging (Manohar et al. 2007)
• Macadamias contain natural plant sterols which contribute to limiting cholesterol reabsorption in the intestines and thus helping reduce LDL cholesterol levels (Patch et al. 2006)
• A source of manganese which contributes to the metabolism of amino acids, carbohydrates and cholesterol and is crucial for bone formation (Aschner & Erikson 2017)
• Tocotrienols, a form of vitamin E that is found in macadamias acts as a preventative factor to diseases such as Alzheimer’s and Parkinson’s due to their antioxidant effect (Bolling et. al 2011)
• 81% of the total fat content of macadamias is from monounsaturated fats (Australian Macadamia Society n.d.). The high monounsaturated fatty acid content of macadamia nuts is understood to reduce the risk of cardiovascular disease, with a study revealing that intake of 42.5g of macadamias daily over 5 weeks reduced serum concentrations of total cholesterol and LDL cholesterol (Griel et. al 2008)
• Nuts including macadamia nuts show an association in managing weight by reducing weight gain and additionally preventing the risk of obesity. This is believed to be due to their fibre and protein content which increases satiety and reduces appetite (de Souza et. al 2017)
• A great source of the water-soluble vitamin, Thiamin, which is imperative for providing the body with energy (Nuts for Life 2020)

The food production of the Northern Rivers region of New South Wales, Australia delivers an abundant harvest in a complex range of soil featuring dry lands and extending to a lush, sub-tropical landscape nestled amongst an idyllic hinterland. Geographically the region stretches from the Clarence River up to the Tweed Heads and Coolangatta border. This area has a diverse agricultural and food production sector with 7.9% of the region’s population were employed in agriculture and 8.5% in manufacturing in 2001.

During this time the local manufacturing strengths were dairy; meat; fruit and vegetable; and bakery production and continues to grow exponentially.  For many, there’s a magnetic attraction to the area with its robust regional landscape, temperate climate and laidback lifestyle – no wonder it has become a haven for so many in recent years. My relationship to the landscape however is all about the sea – at least that is what drew me here over four years ago. Although I love my hometown of Melbourne, I miss its trams, its Chinatown and Asian food, her fine dining, compelling sporting events and my old glamorous city-life, this is a magical place where dolphins dance in a beautiful bay, the food is good and the people laugh – a lot!

The key food industry sectors here include:

• Agriculture
• Value adding/Manufacture
• Distribution
• Retail
• Food Service
• Food Tourism- farm based and regional

It is home to significant market leaders and generates export businesses with regional distributors servicing the market. As a creative hub it is a vibrant and nurturing hotpot for niche market businesses to start up simmer and thrive – especially in gourmet and wellbeing food service.
