结局指标
主要结局
The effect of gluten acutely and sub-acutely on extraintestinal symptoms in HV measured on the Positive and Negative Affect Schedule
时间窗: At the beginning of test visit 0 (day 0), visit 1 (at day 15), test visit 2 (at day 20), after test visit 3 (at day 36), after test visit 4 (at day 41)
Change from baseline. Scores can be 'very slightly or not at all', 'a little', 'moderately', 'quite a bit', 'extremely'. Measured at day 0, day 15, day 20, day 36 and day 41.
The effect of gluten acutely and sub-acutely on extraintestinal symptoms in HV measured on the Profile of Mood State.
时间窗: At the beginning of test visit 0 (day 0), visit 1 (at day 15), test visit 2 (at day 21), after test visit 3 (at day 36), after test visit 4 (at day 41)
Change from baseline. Scores are measured on the Visual Analogue Scale. The scale is ranged 0 - 10, in which 0 no occurrence of the symptom and 10 a lot occurrence of the symptom. Measured at day 0, day 15, day 20, day 36 and day 41.

- Effect of acute and sub-acute gluten administration on gut microbiota composition (stool samples)(After test visit 0 (day 0), day 13 and day 14, after test visit 1 (day 15), day 16, 17, 18, 19 and 20, two days before test visit 3 (day 34 and 35), day 36, 37, 38, 39, 40)
- The effect of gluten acutely and sub-acutely on gastrointestinal symptoms in HV measured on the visual analogue scale for gastrointestinal symptoms(At the beginning of test visit 0 (day 0), visit 1 (at day 15), test visit 2 (at day 21), after test visit 3 (at day 36), after test visit 4 (at day 41))
- Effect of acute and sub-acute gluten administration on high sensitive reactive protein levels in blood samples(During test visit 0 (day 0), test visit 2 (at day 21), after test visit 4 (at day 41))
- Effect of acute and sub-acute gluten administration on Lipopolysaccharide-Binding Protein levels in blood samples(During test visit 0 (day 0), test visit 2 (at day 21), after test visit 4 (at day 41))
