Fiber Blend Changed Gut Bacteria Without Worsening IBS Symptoms in Small Trial
IBS can cause abdominal pain, bloating, gas, diarrhea and constipation, and symptoms vary from person to person.
A low-FODMAP diet can ease symptoms by limiting certain carbohydrates, but it may also reduce fiber intake and beneficial gut bacteria.
Researchers at Edith Cowan University in Australia tested a fiber blend called ur gut in people with IBS who were following this diet.
The blend combines resistant starch and psyllium, and the small trial found changes in gut bacteria without worsening symptoms.
Participants also showed improvements in gut-related anxiety, according to the researchers.
They think psyllium may slow the fermentation of resistant starch, helping it reach farther into the colon, but the trial does not establish how the blend works.
A small clinical trial found that a fiber blend changed gut bacteria in people with irritable bowel syndrome without worsening their symptoms.
Participants were following a low-FODMAP diet, which can reduce fiber intake and beneficial gut bacteria.
The blend, called ur gut, combines high-amylose maize resistant starch with psyllium husk powder.
Researchers at Edith Cowan University developed and tested the blend.
The study also reported improvements in participants’ gut-related anxiety.

What people are saying
We wanted to find a way to build better gut health while following a low-FODMAP diet.
What’s exciting about this study is that participants maintained stable symptoms while showing meaningful improvements in their gut microbiota as well as in their gut-related anxiety.
Changes of this magnitude are rarely seen with such a short intervention.
Our findings suggest we may also be able to actively rebuild gut health and the microbiome while not making IBS symptoms worse.
