Study A and B
- Develops self-reported GI symptoms within 12 hours after a single intake of
bread;
- Aged between 18-70 years;
- Asymptomatic or mildly symptomatic (overall symptoms score with VAS below or
equal to 30 mm) while on their symptom-free diet;
- Must have a freezer (-18ºC) to store the study breads during the study.
Follow-up measurement
- (1) NCWS subject: develops GI symptoms within 12 hours after consumption of
at least one of the study breads of study A or B (+15 mm on VAS); OR (2)
Healthy control (sex matched to NCWS subjects): eats bread regularly (min. 5
days per week)
- Age between 18-70 years;
- Must have a fridge (4-7ºC) to shortly store the collected faecal sample.
Study A and B
- Medical history of coeliac disease, wheat allergy, presence of an organic
gastrointestinal (GI) disease (such as inflammatory bowel disease) or other
disease which may interfere with NCWS symptoms (upon judgment of the
physician-clinical investigator (prof. Keszthelyi, Gastroenterologist MUMC+/
prof. Witteman, PI and consulting gastroenterologist WUR));
- Previous major abdominal surgery or radiotherapy interfering with
gastrointestinal function;
- Use of medication potentially influencing gastrointestinal function and/or
NCWS symptoms is allowed, provided that dosing has been stable for * 1 month
before enrolment;
- Administration of probiotic, prebiotic supplements, investigational drugs or
participation in any scientific intervention study, which may interfere with
this study (to be decided by the principle investigator), in the 14 days prior
to the study.
Follow-up measurement - in addition to the criteria listed above:
- Use of antibiotics during the 6 past months prior to faecal sampling;
- Healthy controls: developing GI symptoms after consumption of bread, or
following a gluten-free or wheat-free diet.
