Not Applicable
Completed
Conditions
Diabetes Type 2
Interventions
Dietary Supplement: Maltodextrin
Registration Number
NCT02569684
Lead Sponsor
Oslo University Hospital
Brief Summary

The aim of the study is to compare the effects of prebiotics versus placebo on blood concentrations of glucagon-like peptide-1 in subjects with diabetes type 2.

Detailed Description

We looked at 6 weeks supplementation with a prebiotic fibre mix of inulin and FOS. Cross over design compared to maltodextrin as placebo. Additional outcome measures: blood glucose, insulin, GLP-2, ghrelin, PYY and leptin after a standardized mixed meal test. Also measured changes in microbiota composition and SCFA in feces before and after intervention/placebo periods, and subjective measures of appetite.

Primary Outcome Measures
NameTimeMethod
Changes in plasma GLP-1 in response to standardized test meal before and after six weeks of ingestion of prebiotic fibers or placebosix weeks

The changes in GLP-1 response to either prebiotic fibers or placebo will be compared in a cross-over manner where the participants are their own controls. In between the intervention periods there will be a wash-out period of 4 weeks.
