Gut Microbiota Shifts During a 12-Week Indigenous Arctic Diet Intervention

29 fecal samples were collected from a single participant before, during, and after a 12-week dietary intervention switching from a Western to an Indigenous Arctic diet. The data, generated via 16S rRNA gene sequencing and analyzed for diversity metrics and taxonomic composition, was authored by Mads B. W. Bjørnsen and published on figshare in 2026. The study provides preliminary evidence of significant gut microbiota restructuring linked to the dietary change.

Use Cases

• Analyzing longitudinal changes in alpha and beta diversity based on fecal sample collection over a dietary intervention period
• Investigating shifts in Firmicutes/Bacteroidota ratios based on measurements taken before, during, and after the Arctic diet phase
• Tracking the presence and absence of specific bacterial genera like Prevotella 9 and Photobacterium based on taxonomic composition analysis
• Studying the partial reversibility of microbial community structure based on comparisons between diet phases

Strengths

• Includes 29 longitudinally collected fecal samples from a single participant
• Provides specific metrics like Firmicutes/Bacteroidota ratios increasing from 1.31 to 2.12
• Documents the appearance of genera like Photobacterium during the Arctic diet phase

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Based on a single-participant pilot study, limiting generalizability
