Dietary Triggers of Gastrointestinal Symptoms in IBS Patients

This crossover randomized controlled trial will evaluate the effects of gluten and gluten combined with amylase-trypsin inhibitors (ATIs) on inducing intestinal and extra-intestinal symptoms in irritable bowel syndrome (IBS) patients. All participants will be put on a gluten-free diet and then challenged with muesli bars containing either purified gluten, gluten with ATIs, or nocebo.

Purified gluten

1 low FODMAPs, vegan muesli bar containing purified gluten per day for 1 week, for a total of 10 g purified gluten per day.

Non-purified gluten (containing ATIs)

1 low FODMAPs, vegan muesli bar containing whole wheat flour with non-purified gluten per day for 1 week, for a total of 10 g non-purified gluten per day.

Nocebo

1 gluten-free, ATI-free, low FODMAPs, vegan muesli bar per day for 1 week. This is a nocebo because we expect that participants will feel worse even though there is no potential irritant.
