STUDY OBJECTIVES

ROQUETTE has developed solutions contributing to the prevention of major health concerns worldwide. Among these solutions, NUTRIOSE® is a soluble non-viscous fiber produced from wheat or maize starch with a fiber content of 85% (on D.S). The objectives of the present research were to demonstrate in healthy volunteers that NUTRIOSE® shows:

 

  a modulation of gut microbiota   
   an attenuation of blood glucose spikes following a carbs challenge
    a sustained release of energy through colonic fermentations

 

METHODS

Short term impact on glucose management (study 1)

  • Cross-over study (Eurofins Optimed)
  • Healthy volunteers (n=6)
  • 50g intake of NUTRIOSE® or glucose
  • 1-day study

Long term impact on microbiota and glucose management (study 2)

  • Cross-over study (University of Reading)
  • Normal weight (n=20) and overweight (n=16) volunteers
  • 14g/day of NUTRIOSE® or an energy-matched placebo as a mid-morning and mid-afternoon drinks
  • 28-day study

Sustained energy release (study 3)

  • Cross-over study (CRNH Rhône-Alpes)
  • Healthy volunteers (n=12) 
  • Standardized breakfast with 50g of NUTRIOSE® or maltodextrin enriched in 13C to follow their metabolic fate
  • 1-day study

RESULTS

 Blood glucose management  

 

Figure 2: Evolution of Glycaemia after product intake 

Glycaemic response of NUTRIOSE® : 25%
 

Figure 3: Evolution of Glycaemia after carbohydrates challenge

  • After 14 and 28 days of NUTRIOSE® consumption, attenuation of the maximum blood glucose concentration following orange juice intake
  • AUC (from 0 to 30 min) different at day 14 and day 28 between groups (p<0.05)
 NUTRIOSE® limits hyperglycaemic peaks and attenuates the blood glucose impact of carbohydrates intake
Digestive health    

Figure 4: Relative abundance using faecal 16S rRNA sequencing 

  • Increase in the saccharolytic Parabacteroides genus (a Bacteroides subgroup of the phylum Bacteroidetes) 
  • Lower microbial diversity (Shannon Index) in normal weight volunteers (p<0.003); data not shown 

Figure 5: Faecal bacterial data from FISH analysis

  • Increase in Clostridium cluster IX, a propionate producing bacterial group 
  • Increase in faecal propionate within the NUTRIOSE® group (p<0.05); data not shown
  NUTRIOSE® selectively modulates the gut microbiota composition 

 

Sustained energy release   

 

Figure 6: Breath hydrogen response 

  • Significant increase in breath H2 excretion 
  • Demonstration of prolonged colonic fermentations

Figure 7: Metabolites oxidation levels occuring during intestinal digestion and colonic fermentation through 13CO2 expired 

 

  • Control group: Breath 13CO2 increase shortly after breakfast ingestion, reflecting intestinal digestion into glucose and further glucose oxidation
  • NUTRIOSE® group: 
    - Immediate slight 13CO2 appearance reflecting a poor digestion in the small intestine
    - Followed by a steady and prolonged 13CO2 appearance reflecting oxidation of Short Chain Fatty 
      Acids from the prolonged colonic fermentation pattern
 

NUTRIOSE® displays prolonged colonic fermentations and subsequent prolonged metabolites oxidation

 

CONCLUSION

NUTRIOSE® acts as a highly targeting prebiotic. This soluble fiber may be used as an integrated solution to improve blood glucose management as NUTRIOSE® helps maintaining healthy blood glucose levels and controls fluctuations after a carbohydrates challenge. Sustained colonic fermentations from NUTRIOSE® contribute to the daily energy supply for whole-body metabolism, and may be a key factor in providing long-lasting energy. The potential health benefits of NUTRIOSE® may be attributed to a specific gut ecosystem modulation
