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

A longitudinal pilot study of gut microbiota dynamics during a dietary transition from a Western to an Indigenous Arctic animal-based diet. The dataset includes 29 fecal samples analyzed via 16S rRNA gene sequencing, profiling bacterial community shifts. The study was authored by Mads B. W. Bjørnsen and published on figshare under a CC-BY-4.0 license.

Use Cases

• Analyzing changes in Firmicutes/Bacteroidota ratios based on dietary phases described in the study
• Modeling beta diversity shifts in gut microbiota associated with the introduction of an Arctic diet
• Investigating the prevalence of protein- and fat-associated taxa like Bacteroides and Alistipes during dietary intervention
• Studying the potential microbial transfer via gastrophagy by tracking genera like Photobacterium

Strengths

• Longitudinal design with 29 fecal samples collected before, during, and after the intervention
• Specific metrics reported, including F/B ratio changes from 1.31 to 2.12 during the Arctic diet phase
• Detailed methodological description using 16S rRNA gene sequencing of the V3-V4 region

Limitations

• Single-participant study, which limits generalizability of findings
• Row count and column-level documentation are unknown, requiring manual inspection after download
• Dataset size is 184.7 KB, indicating a very limited scope and scale
