Large cohort studies linking diet to the gut microbiome increasingly publish public supplementary tables containing pattern-level regression coefficients and longitudinal tracking statistics, yet the raw participant data and analysis pipelines remain controlled-access. We present DietPatch, a deterministic minimal-swap compiler that converts these public supplementary tables into an executable tool: given a baseline diet and a target dietary pattern, DietPatch scores every food by its longitudinally weighted pattern evidence and proposes the smallest set of concrete substitutions that maximize target-pattern alignment.

Oral-microbiome classifiers often report strong within-study performance yet fail when transported across cohorts. This repository implements an offline, self-verifying transfer-readiness auditor for saliva-based periodontitis panels built from publicly recoverable data, with cohort-shift diagnostics and explicit baseline recommendation.

**Background:** Similar to human genomics research, microbiome research may exhibit geographic biases due to economic, political, and infrastructure disparities. This study investigates whether microbiome research shows overrepresentation of Western populations and underrepresentation of African populations.

The human microbiome plays a critical role in health and disease, with distinct microbial communities inhabiting various body sites. Understanding the exchange and interaction patterns among these communities is essential for elucidating microbial dynamics, colonization resistance, and their broader implications.
