Study reveals benefits of chicory root fiber intake

It promotes significant growth of Bifidobacteria in the gut microbiome in all age groups and improves bowel function, according to BENEO.

A new systematic literature review with meta-analyses, conducted by Dávid U. Nagy et al., revealed that chicory root fiber intake (starting at 3g/day) promotes significant growth of Bifidobacteria in the gut microbiome in all age groups and improves bowel function parameters, according to BENEO.

It is the first study of this kind, based on randomized control trials, that has investigated the effect of inulin-type fructans derived from chicory root on Bifidobacteria abundance in gut microbiota and health-related outcomes, BENEO added.

Included in the systematic review with meta-analyses, considered the strongest methodology in the hierarchy of scientific evidence, were 50 human intervention studies, with a total of 2,495 participants. These were selected based on an extensive literature search and review process that followed the guidelines of the Cochrane Handbook for Systematic Reviews and Interventions.

This research evidenced that inulin, oligofructose, and combinations thereof, derived from the chicory root as the source of origin, act as a bifidogenic factor, promoting the selective growth of Bifidobacteria. The systematic review with meta-analyses also demonstrates that chicory root fiber is a prebiotic that complies with the ISAPP (International Scientific Association for Probiotics and Prebiotics) definition of prebiotics.

The researchers further reported that the bifidogenic effects of the chicory root fibers were accompanied by improved bowel regularity. This was validated by increased stool frequency in healthy adults, and by softer stools in healthy infants and children.

“I am extremely pleased that this detailed critical systematic review with meta-analyses has been conducted," said Anke Sentko, vice president, regulatory affairs & nutrition communication at BENEO. "Following the highest quality scientific evidence methodology, the prebiotic effect of inulin-type fructans sourced from the chicory root is confirmed. It yet again shows that integrating chicory root fibers into a person’s daily diet supports Bifidobacteria and thus their gut microbiome, while also improving the bowel functions of the very young to the very old."
