Introducing sorghum

Climate and weight friendly grain
Sorghum is the fifth most important cereal crop in the world after wheat, rice, corn and barley. And it's easy to understand why - sorghum is highly drought and heat tolerant plus lab tests have found it has higher antioxidant activity than other cereals and fruit.

Typically a stock feed, with the majority of Australia's harvest used as feed grains to the beef, dairy, pig, poultry or pet food industry, sorghum is not used widely as a food for human consumption in Australia. Sorghum is highly drought and heat tolerant, with about 60% of Australia's crop grown in the hot regions of Queensland and Northern NSW. Able to grow without much water, sorghum is generally very economical and also a good rotation crop. With constant reminders of climate change a concern amoungst scientists, politicians and everyday Australian's, sorghum could be utilised as a sustainable crop for human consumption.

Food chemist and researcher Stuart Johnson from Curtin University is working with food manufacturers Sanitarium and George Weston Foods who are already using sorgham in some products like breads and breakfast cereals, to help boost the use of this former stock-feed grain in the Australian food industry. This idea is not new in some parts of the world, where sorghum is relied upon as a staple food crop in Africa, Central America, and South Asia. Foods prepared with sorghum include popcorn, porridge, flour for baked goods and it is even brewed into beer. As sorghum is naturally gluten free, it is a great alternative to gluten-containing grains like wheat, barley and rye for those people with coeliac disease.

Although more research needs to be done, lab studies have found that wholegrain sorghum has a higher antioxidant activity compared to other cereals and fruits. It has a lower protein content than other cereals, but is a good source of B vitamins such as thiamin, riboflavin, vitamin b6, biotin and niacin; important for many vital body processes including energy metabolism. Also relatively high in potassium and phosphorus, like most other wholegrains sorghum is also high in dietary fibre.

Coloured varieties of sorghum (red, brown and black) are particularly rich sources of various phytochemicals, and animal studies have shown encouraging results for the use of this grain to help in the fight against type 2 diabetes, heart disease and some cancers via its antioxidant properties, and obesity by suppressing appetite.

According to some, sorghum has huge potential, given its agronomic properties in favour of climate change and cost effectiveness, in addition to the emerging science behind its promising benefits in human health and disease. Whilst currently limited to health food shops and a small range of supermarket product lines, stay tuned as prospective clinical research trials are expected to give support to sorghum becoming more widespread in our food supply to aid in the battle against chronic disease.

Research proves wholegrain benefits

Cereals & snacks provide antioxidant boost!

Dietitians often recommend green tea, red wine, nuts and fruits (especially berries) for their antioxidant boost! New research has discovered that many wholegrain breakfast cereals, and wholegrain snacks like popcorn and wholegrain crispbreads, have surprisingly large amounts of polyphenols, regarded as great antioxidants.

Researchers investigated the total polyphenol content of around 40 breakfast cereals and 20 snacks and found that wholegrain products have comparable antioxidants per gram to fruits and vegetables. The study revealed higher antioxidant levels than previous studies because the researchers analysed total polyphenol content rather than focusing on free antioxidants, which are not bound to sugar.

Ready to eat, cold breakfast cereals made with oats were found to have the highest antioxidants, followed by corn and wheat. Popcorn was at the top of the snack list, blitzing the competition with as much as five times as many antioxidants as the nearest rival.

Packed with vitamins, minerals and fibre along with polyphenols, scientific studies have found that regular consumption of wholegrain foods can reduce the risk of coronary heart disease, diabetes, certain cancers and even help you to manage your weight. So jump on the wholegrain train!

• Try air popping your own corn kernels and use herbs to replace salt. Garlic powder, chilli powder, basil and oregano work well.
  
• Did you know plain popcorn, without added butter or sugar, contains around 4 times less saturated fat and 5 times more fibre than you average potato crisps? So choose low fat or homemade popcorn next time you feel like a snack.
  
• Popcorn is a wholegrain! One 20g serve of plain popcorn contains around 15g of wholegrains - that's 30% of your daily target intake for wholegrains! (as recommended by Go Grains Health & Nutrition).
