Description
A randomized, double-blinded, controlled pilot study of 124 healthy male adults, conducted by Caroline Perreau, investigating the effects of resistant dextrin supplementation on gut microbiota composition and function. The dataset includes results from participants with high and low baseline fiber intake, with measurements taken before, during, and after a 4-week intervention period. The data was last updated on May 20, 2026.
Use Cases
Analyzing changes in the relative abundance of the Parabacteroides genus based on supplementation and baseline diet.
Comparing gut microbiota functional gene activity, such as α- and β-glucosidase, between treatment and placebo groups.
Investigating the differential response of specific bacterial species like P. distasonis to dietary fiber intervention.
Evaluating the effect of supplementation on fecal parameters like pH, short-chain fatty acids, and secretory IgA.
Strengths
Dataset is derived from a randomized, double-blinded, placebo-controlled trial, a robust study design.
Includes results from 124 subjects with detailed subgroup analysis (57 high-fiber, 67 low-fiber).
Measures multiple outcome variables including microbiota composition, function, and fecal biomarkers.
Limitations
The dataset is very small at 19.2 KB, indicating limited raw data or summary-level results only.
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for certain analyses.
