Effect of Two Different Rye Bread Types in Irritable Bowel Syndrome

March 28, 2015 updated by: Oy Karl Fazer Ab

Effects of Traditional and Low-FODMAP Rye Bread in Irritable Bowel Syndrome.

The purpose of this study is to evaluate if low-FODMAP (Fermented Oligo-, Di-, Monosaccharides And Polyols) rye bread is better tolerated in irritable bowel syndrome than commonly available traditional rye bread higher in FODMAP carbohydrates. The study also aims to investigate patients' compliance to rye bread regimen, potential changes is gut microbiota and hydrogen production during the test periods (a marker of large bowel fermentation of poorly absorbed carbohydrates).
