NCT02308397

Brief Summary

The aim of the study is to produce a tolerable alternative to normal wheat bread which would be suitable for subjects with self-reported non-coeliac gluten sensitivity (NCGS). The bread would be made from wheat so, in contrast to gluten-free bread, would be more comparable to standard bread. To make this bread, the investigators will use advanced enzyme technology and/or novel formulations to target the digestion or removal of wheat proteins, which might be involved in the etiology of non-coeliac gluten sensitivity, preferentially over other those that are more useful for baking quality. The investigators will determine palatability and tolerance of this new product in a human cross-over, randomised, blind and placebo-controlled intervention study. It has been estimated 6-10% of the population are sensitive to gluten who do not have coeliac disease (CD). Three breads will be produced and tested in this study against a suitable reference based on standard wheat flour and baking process

Outcome Measures

Primary Outcomes (1)

  • Change in the presence and severity of overall and individual gastrointestinal symptoms (daily diary cards via a 100-mm VAS to score)

    Gastrointestinal symptoms will be assessed by the participant completing daily diary cards via a 100-mm VAS to score the presence and severity of abdominal pain, bloating, wind and nausea.

    These will be assessed daily during baseline week (0), treatment week (1, 4, 7 and 10) and washout week (3, 6 and 9)

Secondary Outcomes (1)

  • Change in the presence and severity of daily fatigue (Daily-Fatigue Impact Scale (D-FIS)

    Fatigue will be assessed daily during baseline week (0), treatment week (1, 4, 7 and 10) and washout week (3, 6 and 9)

Other Outcomes (1)

  • Measurement of biomarkers as in detailed description of the study section

    These will be measured singularly during baseline week (0)
