FIGURE 6.

From an irritable bowel syndrome sub‐cohort, 392 persons (12.3% of the cohort, 307 females and 85 males), complained of gastrointestinal symptoms after the consumption of gluten‐containing foods. Of these patients 6.63% were diagnosed to suffer from coeliac disease and 0.51% from wheat allergy (WA). The remaining 337 persons were all put on a 6‐months strictly gluten‐free (GF) diet, followed by a reintroduction of gluten‐containing grains in their diet for 1 month. Despite their self‐diagnosis to be gluten sensitive, 85.96% of these individuals showed no specific reaction to gluten. CD, coeliac disease; NCGS, non‐coeliac gluten sensitivity.
