Gut Microbiota Shifts During a 12-Week Transition to an Indigenous Arctic Diet

A longitudinal pilot study tracks gut microbiota changes in a single participant switching from a Western diet to a 12-week Indigenous Arctic animal-based diet. The dataset includes 29 fecal samples analyzed via 16S rRNA gene sequencing, measuring diversity metrics and taxonomic composition. The data was published by Mads B. W. Bjørnsen under a CC-BY-4.0 license.

Use Cases

• Analyzing shifts in Firmicutes/Bacteroidota ratios based on dietary phases described in the study
• Modeling beta diversity changes in gut microbiota during a dietary transition
• Investigating the prevalence of taxa like Prevotella 9 and Bifidobacterium in response to diet changes
• Studying the potential microbial transfer from gastrophagy (consuming dried whole fish with intestinal contents)

Strengths

• 29 fecal samples provide a dense longitudinal profile for a single participant
• Analysis includes specific metrics like Firmicutes/Bacteroidota ratio, which increased from 1.31 to 2.12
• Data captures a unique dietary intervention involving raw, dried, and fermented animal-source foods

Limitations

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