Wheat is the most widely grown food crop and the most traded cereal in the world today. It is therefore a perfect foundation for raising the nutritional quality of the food supply to help improve overall health of communities worldwide. Selective breeding of commercial wheat has produces a variety which is very high in resistant starch, a type of dietary fibre which has documented beneficial metabolic effects for glucose and lipid metabolism. Dietary fibre is the nearest thing we have to a super-food with the known beneficial effects on the gut microbiome, gastrointestinal cancers and metabolic disease, but intakes fall well below recommended levels. The question is, can this new type of wheat can fill this fibre-gap?This high-amylose wheat clearly has a great potential to improve human health if it enters the food chain, but at the moment there are several challenges which need to be overcome such as understanding how to incorporate this high insoluble-fibre wheat into food staples in the diet such as bread, biscuits and pastry, and further define the metabolic effects of consumption in humans.Using a combination of cutting-edge food technology methods and dietary interventions in human volunteers, this project aims to investigate and maximise the incorporation of this wheat into different food products; evaluate the sensory qualities and consumer attitudes to this novel wheat variety and quantitate the glucose lowering effects of consumption in a dietary intervention trial.

小麦是当今世界上最广泛种植的粮食作物，也是世界上谷物最多的谷物。因此，它是提高粮食供应的营养质量，以帮助改善全球整体健康状况的理想基础。商业小麦的选择性繁殖产生了一种耐药性淀粉的种类，这是一种饮食纤维，它记录了对葡萄糖和脂质代谢的有益代谢作用。饮食纤维是我们与肠道微生物组，胃肠道癌和代谢疾病的已知有益作用的最接近的东西，但摄入量远低于推荐水平。问题是，这种新型的小麦可以填补这种纤维间隙吗？这种高淀粉蛋白的小麦显然具有巨大的潜力，可以改善人类健康，但目前存在一些挑战克服诸如了解如何将这种高的不溶性纤维小麦融入饮食中的食物主食，例如面包，饼干和糕点，并进一步定义了人类消费的代谢影响。该项目对人类志愿者的干预措施旨在调查和最大化这种小麦融入不同的食品。评估对这种新颖的小麦品种的感觉品质和消费者态度，并在一项饮食干预试验中量化消费的葡萄糖降低作用。
