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.

小麦是当今世界上种植最广泛的粮食作物和交易量最大的谷物。因此，它是提高食品供应营养质量的完美基础，有助于改善全球社区的整体健康状况。商品小麦的选择性育种已经产生了抗性淀粉含量非常高的品种，抗性淀粉是一种膳食纤维，已经证明对葡萄糖和脂质代谢具有有益的代谢作用。膳食纤维是我们拥有的最接近超级食物的东西，对肠道微生物组，胃肠道癌症和代谢疾病具有已知的有益作用，但摄入量远远低于推荐水平。问题是，这种新型小麦能填补纤维缺口吗？这种高直链淀粉小麦如果进入食物链，显然具有改善人类健康的巨大潜力，但目前需要克服几个挑战，例如了解如何将这种高不溶性纤维小麦纳入面包，饼干和糕点等饮食中的斯台普斯，并进一步确定人类消费的代谢效应。使用尖端食品技术方法和人类志愿者的饮食干预相结合，这项计划旨在研究及尽量将这种小麦加入不同的食品中;评估这种新品种小麦的感官品质及消费者的态度;以及在饮食干预试验中量化食用这种小麦对降低血糖的效果。
