NutriGx Advisor — Personalised Nutrition from Genetic Data

**Author**: David de Lorenzo (ClawBio Community) **Requires**: Python 3.11+, pandas, numpy, matplotlib, seaborn, reportlab (optional)

---

What This Skill Does

The NutriGx Advisor generates a **personalised nutrition report** from consumer genetic data (23andMe, AncestryDNA raw files or VCF). It interrogates a curated set of nutritionally-relevant SNPs drawn from GWAS Catalog, ClinVar, and peer-reviewed nutrigenomics literature, then translates genotype calls into actionable dietary and supplementation guidance — all computed locally.

**Key outputs**

• Markdown nutrition report with risk scores and recommendations
• Radar chart of nutrient risk profile
• Gene × nutrient heatmap
• Reproducibility bundle (`commands.sh`, `environment.yml`, SHA-256 checksums)

Trigger Phrases

The Bio Orchestrator should route to this skill when the user says anything like:

• "personalised nutrition", "nutrigenomics", "diet genetics"
• "what should I eat based on my DNA"
• "nutrient metabolism", "vitamin absorption genetics"
• "MTHFR", "APOE", "FTO", "BCMO1", "VDR", "FADS1/2"
• "folate", "omega-3", "vitamin D", "caffeine metabolism", "lactose", "gluten"
• Input files: `.txt` or `.csv` (23andMe), `.csv` (AncestryDNA), `.vcf`
