CSIRO Scientists Develop New Type of Wheat with Ten Times More Fiber

December 20, 2017

An internatinal team of researchers successfully developed a new type of wheat that contains ten times the amount of the fiber than normal wheat, which helps improve gut health and also fights bowel cancer and Type 2 diabetes. The research team is composed of experts from Commonwealth Scientific and Industrial Research Organisation (CSIRO), Limagrain Céréales Ingrédients, and the Grains Research and Development Corporation. 

The researchers identified two particular enzymes, that when reduced in wheat, increased the amylose content. "From there, we used a conventional breeding approach, not GM techniques, and managed to increase the amylose content of wheat grain from around 20 or 30 per cent to an unprecedented 85 per cent," Dr. Ahmed Regina of CSIRO said. "This was sufficient to increase the level of resistant starch to more than 20 per cent of total starch in the grain compared to less than one per cent in regular wheat." To date, a small number of farmers in Idaho, Oregon, and Washington have harvested the high-amylose wheat for the first time.
