- In 2017, the International Scientific Association for Probiotics and Prebiotics (ISAPP) has defined a prebiotic as “a substrate that is selectively utilized by host microorganisms conferring a health benefit”. NUTRIOSE® is a soluble non-viscous fiber produced from wheat, maize or pea starch with supporting science showing that this fiber is slightly digested in the small intestine and progressively fermented all along the colon.
The objective of the present research was to investigate the impact of NUTRIOSE® soluble fiber on gut microbiota modulation in healthy volunteers.
| Healthy volunteers
| Daily intake:
- 20g glucose (control)
- 10.15 or 20g NUTRIOSE®
|Fecal microbiota using culture methods|
| Daily intake:
- 8g glucose (control)
- 8g NUTRIOSE®
|Fecal microbiota using real-time PCR analysis|
n=20 normal weight
| Daily intake:
- 7g maltodextrin (control)
- 14g NUTRIOSE®
Fecal microbiota using using fluorescence in situhybridization & 16S rRNA sequencing
Significant increase in the saccharolytic bacteria following the administration of 10g/day (study 1) or 8g/day (study 2) of NUTRIOSE® compared to baseline.

Significant decrease following the administration of 15g/day (study 1) or 8g/day (study 2) of NUTRIOSE® compared to baseline.

Significant increase in the saccharolytic Parabacteroides genus, a Bacteroides subgroup of the phylum Bacteroidetes.
NUTRIOSE® supplementation selectively modulates gut microbiota to a healthier composition. Previously, several studies have demonstrated the health benefits of NUTRIOSE® in blood glucose management, digestive health and sustained energy release. Many of these health benefits produced by NUTRIOSE® were thought to be driven by the selective modulation of the gut microbiota. Collectively all these results show that NUTRIOSE® meets the requirement of the definition of a prebiotic as defined by ISAPP. NUTRIOSE® soluble fiber can be considered as an emerging prebiotic.
