Combining Cereals With Pulses - Reduced Gastrointestinal Symptoms?

October 4, 2021 updated by: Kaisa Linderborg, University of Turku
The aim of the study is to compare self-reported gastrointestinal symptoms and intestinal fermentation rates of the study products as measured by breath hydrogen and methane in adult population with self-reported mild abdominal sensitivity to pulses. The study products are a pulse products with two different cereals.

Detailed Description

The study is a randomized, controlled, double-blind, cross-over intervention trial. The aim is to recruit 25 subjects to the trial. The study will be conducted with a cross-over setting, where the subjects will go through exposure meals and breath gas measurement two times (two different test products) in a randomized order. The study meals are identical in appearance but differ in fiber content. After study breakfast the breath gases are analyzed every 15 minutes during 8 hours.
