Gut Microbiota Response to Resistant Dextrin Supplementation in a Pilot Clinical Study

124 healthy male adults participated in a 4-week randomized, double-blind, placebo-controlled trial to evaluate the effects of 15 g/day resistant dextrin on gut microbiota. The dataset likely contains measurements of fecal bacteria abundance, short-chain fatty acids, pH, and stool consistency. It was authored by Caroline Perreau and uploaded to figshare in May 2026.

Use Cases

• Analyzing changes in Parabacteroides genus abundance based on fiber supplementation and diet group.
• Comparing gut microbiota functional gene activity related to glucosidase and propionate production between treatment arms.
• Investigating the relationship between dietary fiber intake level and the magnitude of microbiome modulation.

Strengths

• Data originates from a randomized, double-blind, placebo-controlled trial, a robust study design.
• Includes results from 124 participants with a mean age of 36.2 ± 11.6 years.
• Measures multiple outcomes: microbiota composition, SCFAs, pH, secretory IgA, and stool frequency/consistency.

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 small (17.0 KB), indicating limited scope, likely containing summary results rather than raw individual-level data.
