Delivering dietary fibre via improved

项目摘要

Dietary fibre (DF) is essential for human health, improving gastro-intestinal function and reducing the risk of a range of chronic diseases (including type 2 diabetes, cardio-vascular disease and types of cancer). However, most UK consumers do not eat DF, with the average daily intake being 17.2 g for women and 20.1g for men, compared with a target of 30g. Cereal products are the major source of DF in the UK diet, with bread alone contributing about 20%. However, the contribution from wheat is limited by the fact that most wheat products are made from white flour, which contains about 3.5% DF compared with 11.5-15.5% in wholemeal. We have therefore identified wheat lines with high DF in white flour, which can be used to develop high fibre wheat lines for UK farmers and products for UK consumers. The proposal will remove the constraints to the development of high fibre lines and products in the UK, by collaborating with four wheat breeders, 2 milling and baking companies and the organisations representing the milling (NABIM) and baking (Federation of Bakers) sectors.This will be achieved in two ways: by providing high fibre pre-breeding lines and molecular makers to wheat breeders, and high fibre lines to millers and bakers to optimise their processes. These advances will be disseminated by the BBSRC Designing Future Wheat programmes and by NABIM and FoB. It will therefore have a fundamental impact on the diet and health of UK consumers.

饮食纤维（DF）对于人类健康至关重要，改善胃肠道功能并降低各种慢性疾病的风险（包括2型糖尿病，心血管疾病和癌症类型）。但是，大多数英国消费者不吃DF，女性的平均每日摄入量为17.2 g，男性为20.1克，而目标的平均摄入量为30克。谷物产品是英国饮食中DF的主要来源，仅面包贡献了约20％。但是，小麦的贡献受到以下事实的限制：大多数小麦产品是由白面粉制成的，该面粉含有约3.5％的DF，而全麦则为11.5-15.5％。因此，我们已经确定了白色面粉中DF高的小麦线，可用于为英国农民开发高纤维小麦线，并为英国消费者开发产品。该提案将通过与四个小麦育种者，2家磨坊和烘焙公司以及代表铣削（NABIM）和烘焙（面包师联合会）领域的组织合作，通过两种方式与高光纤前的生产者和培养基的生产商来实现磨坊（Nabim）和烘焙（联合会），从而消除英国高纤维生产线和产品开发的限制。优化他们的流程。这些进步将被BBSRC设计未来的小麦计划以及Nabim和FOB传播。因此，这将对英国消费者的饮食和健康产生根本影响。
