13TSB_N4L2CRD: High fibre wheat for healthier white bread
Lead Research Organisation:
Rothamsted Research
Department Name: Plant Sciences
Abstract
The aim of this industry led project is to increase the intake of soluble dietary fibre of the general population, providing Nutrition for Life to consumers of white bread, many of which are children. Today, almost 55% of all bread consumed is white bread with very little fibre content, and partly responsible for the low fibre intake by the majority of the population. This project will use already identified high fibre wheat to develop a wheat variety suitable for UK conditions with good bread making quality. KWS, the plant breeding company in the project, will work closely with academic partners to make this possible, while M&S will investigate the quality and nutritional value of bread made from high soluble fibre wheat, as well as exploit initial market opportunities. This project involving a unique composition of plant breeders, retail industry, quality and genetic experts will only be feasible with financial support from TSB.

Planned Impact
Cereal products contribute 29/30% of the total energy daily intake of adult males/females, 22/21% of the intake of protein and 39/37% of the intake of non-starch polysaccharides (ie. dietary fibre, DF) (NDNS, 2011). Similarly, Steer et al. (Proceedings of the Nutrition Society 2008, Vol 67, E363) showed that bread products alone contributed 12% of the protein, 20% of the fibre and 16% of the iron to the adult UK diet, with white bread alone contributing 11% of the dietary fibre.
There is a clear and widely accepted need to increase the intake of dietary fibre in the UK diet, from the current 1.3g per day to the recommended intake of 18g per day. Doubling the content of DF in white bread could therefore contribute an additional 1.43g fibre to the daily intake.
The financial benefits of increasing dietary fibre to consumers are more difficult to quantify as they relate to quality of life and reduced health care costs. However, there are massive projected increases in disease for which the risk factors include low dietary fibre: clinical obesity in UK adults to 50% of the population by 2050, type 2 diabetes by 20-fold, hypertension by 5-fold, CVD by 2.5-fold and some cancers by 3-fold. These figure indicate that even small improvements in diet could have a significant impact on health, with associated reductions in health care costs.

Description | The project has shown that increasing the content of arabinoxylan fibre in white bread reduces the rate of food breakdown and glucose release in model gastro-intestinal system, which should reduce the glycaemic index of the food. QTL analysis of the fibre (arabinoxylan) content of white flour has identified two major QTLs, on chromosomes 1B and 6B. A molecular marker has been developed for the 1B QTL and validated using high AX lines produced by conventional breeding. This knowledge is underpinning the development of high fibre cultivars in a project funded by Innovate UK. |
Exploitation Route | Development of commercial high fibre wheat lines and high fibre white flour products including bread. This is addressed in a new LINK proposal to BBSRC |
Sectors | Agriculture, Food and Drink,Healthcare |
Description | The outcomes from the project, and in particular the demonstration that it is possible to produce good white bread from high fibre wheat, have underpinned an Innovate UK project on developing new types of wheat for the commercial production of high fibre white bread. This project includes 2 commercial partners: KWS wheat Breeding and M & S. The results from the project form the basis for a new LINK proposal submitted to BBSRC: this includes 4 breeders and 2 milling/baking companies |
