Dietary Fibre Blend Improves Gut Health in Irritable Bowel Syndrome Patients
A specific dietary fibre blend combining resistant starch and psyllium husks improves gut health in irritable bowel syndrome (IBS) patients following a low-FODMAP diet, without worsening symptoms like abdominal pain and bloating, according to research published in the European Journal of Nutrition. Researchers at the Edith Cowan University Nutrition and Health Innovation Research Institute conducted a randomized, double-blind controlled study examining the effects of the fibre blend, marketed as ur gut®. The findings show that the formulation stabilizes IBS symptoms while positively altering the gut microbiota and reducing gut-related anxiety.
Edith Cowan University Trial Results and Fermentation Mechanism
The study investigated participants who had previously completed a low-FODMAP diet, an eating pattern that restricts fermentable oligo-, di-, monosaccharides, and polyols. While this dietary approach reduces gastrointestinal distress, it often significantly limits long-term fibre intake. The tested fibre blend relies on an interaction between resistant starch and psyllium husks. The psyllium delays the fermentation process of the resistant starch. This slowing mechanism allows the nutrient to travel deeper into the large intestine rather than being rapidly broken down in the upper section where it typically triggers discomfort.
Fibre Regimen Improves Gut Microbiota and Reduces Anxiety
Study participants exhibited notable improvements across multiple health markers during the intervention period. Alongside the stability of their IBS symptoms, which did not increase under the fibre regimen, subjects showed measurable enhancements in their gut microbiota composition. Investigators observed a decrease in gut-related anxiety among the participants. This reduction points to an alleviation of stress within the complex signaling network connecting the gastrointestinal tract and the central nervous system.
Prevalence of Irritable Bowel Syndrome in Australia
Irritable bowel syndrome represents a widespread public health burden, affecting nearly eleven percent of the Australian population. To help patients manage their condition practically, the research team at Edith Cowan University developed a companion cookbook to accompany the scientific investigation. The commercial fibre product ur gut® remains available for regular purchase through retail channels, providing an accessible dietary option for individuals managing functional gastrointestinal disorders after completing restrictive elimination diets.
