Clinical Trial Summary

The goal of this randomized, double-blind, placebo-controlled study is to investigate the effect of expectancy related to gluten consumption versus actual gluten intake on overall GI symptoms in individuals with non-coeliac gluten sensitivity (NCGS) The main questions it aims to answer are: - what is the effect of consumer expectancy, related to either gluten-containing or gluten-free oat bread, on short-term (within 8 hours) overall GI symptoms in individuals with NCGS? - what is the effect of actual gluten intake on short-term (within 8 hours) overall GI symptoms in individuals with NCGS Participants will be randomised into four groups: 1. Participants with the expectation of receiving gluten-containing bread and actually receiving gluten-containing oat bread during the test day. (E+ G+) 2. Participants with the expectation of receiving gluten-containing bread, but actually receiving gluten-free oat bread during the test day. (E+ G-) 3. Participants with the expectation of receiving gluten-free bread but actually receiving gluten-containing oat bread during the test day. (E- G+) 4. Participants with the expectation of receiving gluten-free bread and actually receiving gluten-free oat bread during the test day. (E- G-)


Clinical Trial Description

One on-site test, starting with baseline measurement (T = 0). Thereafter, subjects are told that they will receive two slices of gluten-containing bread (E+) or gluten-free bread (E-). Consequently, they receive breakfast with two slices of bread (gluten-containing (G+) or gluten-free (G-)). After breakfast, questionnaires will be completed every hour for 8 hours. After T = 4 hours, participants receive lunch with two slices of the same bread, combined with the same expectancy, that they received at breakfast. Follow-up measurements include the same questionnaires at the end of day 1 (from end of test day until they go to sleep), at the end of day 2 and at the end of day 3. ;
