Gut Microbiota Response to Resistant Dextrin in a Randomized Controlled Pilot Study

A 2026 pilot study of 124 healthy male adults, split by high or low dietary fiber intake, who received a 4-week supplementation of resistant dextrin or a placebo. The dataset, authored by Caroline Perreau, captures changes in gut microbiota composition, fecal parameters, and stool characteristics from this randomized, double-blinded, controlled trial.

Use Cases

• Modeling the relationship between fiber supplementation and Parabacteroides genus abundance based on trial results.
• Analyzing differential gut microbiota responses in high-fiber versus low-fiber diet populations as described in the study.
• Investigating correlations between resistant dextrin intake and changes in specific bacterial species like P. distasonis.
• Studying the functional impact of supplementation on bacterial gene activities for glucosidase and propionate production.

Strengths

• Data originates from a randomized, double-blind, placebo-controlled trial, a rigorous study design.
• Includes results for 124 subjects with a mean age of 36.2 ± 11.6 years, providing a specific demographic.
• Reports specific, statistically significant findings, such as Parabacteroides increasing to 5.5% from 1.4% with active supplementation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 22.0 KB, indicating limited scope, likely containing summary results rather than raw individual-level data.
