Tree nuts are the original superfoods. Packed full of protein, fibre, essential fats, vitamins and minerals, nuts are now considered so important to our health that the most recent Australian Dietary Guidelines recommends eating a serving of nuts every day (roughly one handful). The Guidelines also advise replacing foods that are high in saturated fat with foods containing polyunsaturated and monounsaturated otherwise known as ‘good’ fats that are found in nuts, avocados and olive oil.
Eating ‘good’ fats is a relatively new concept for Australians, and is at odds with the low fat diet mantra that was popularised in the ‘80s. As a result, nuts and other healthy, natural foods are still avoided by many health conscious shoppers because they are seen as fattening. But this is changing thanks to the work of the Australian Nut Industry initiative Nuts For Life, which is dedicated to debunking the ‘fat myth.’ Chris Joyce, pistachio grower and Chair of Nuts for Life explains:
“By the end of the ‘90s, nuts had such a bad rep that people weren’t eating them at all. But new studies were coming out that showed that people who ate nuts five times a week had half the risk of developing heart disease than those who didn’t. And what really surprised everyone was that there was also research showing that if you eat nuts you don’t put on weight, in fact your more likely to loose weight. We started Nuts for Life around 2002 to make sure this new information was getting out to GPs, nutritionists, health professionals and the general community.”
Research shows that nuts can help people maintain healthy weight levels because they are high in protein and fibre, which suppress hunger. The crunchy texture of nuts also sends satiating signals to the brain, so there is less chance of overindulging.
Nuts can also play a role in the prevention and management of type 2 diabetes. A study of almost 84 000 women found that those who ate a 28g serving of nuts, five times or more per week had a 27 per cent lower risk of diabetes than those who never or rarely ate nuts. The addition of nuts to carb heavy meals also reduces the rise in blood glucose levels after eating
Which nuts should I buy?
Australia produces some of the highest quality nuts in the world, and being an island nation, local farmers have been protected from the pests and diseases that affect nut crops in other countries. As a result most of Australian’s nut production is pesticide free or requires minimal pesticide application.
Australian’s currently eat around 50 per cent domestic product with 50 per cent of nuts still imported from overseas. The unrivalled flavour, freshness and quality of new season nuts mean they are definitely worth seeking out, as Chris Joyce explains:
“Nuts are like fresh fruit and vegetables, they’ve got a finite life – the oils will go rancid. Anything imported is on a boat for the best part of two months, whereas local produce is usually freighted overnight ready for the stores.”
An Australian native bush food, macadamias are full of healthy monounsaturated fats, plant sterols, dietary fibre, copper, magnesium and zinc, which all work together to promote heart health and lower blood cholesterol.
