Individual skill
tooluniverse-nutrition-food-composition
Look up nutrient composition, ingredients, allergens, additives, and processing-level classification for foods and branded products via USDA FoodData Central (authoritative US nutrient values, generic + branded foods) and Open Food Facts (crowdsourced global product database — barcode lookup, allergens, additives, Nutri-Score, NOVA processing classification). Use when someone asks 'how much [nutrient] is in [food]', 'what are the ingredients/allergens in [branded product]', 'look up this barcode', 'find products containing/free of [additive/allergen]', or needs dietary/nutrient data for a clinical or research calculation.

# Nutrition & Food Composition Lookup
Looks up what's actually in a food or branded product — nutrient values, ingredients, allergens, additives, processing classification — from two complementary sources. Does not itself perform toxicological or epidemiological analysis; feed the retrieved data into `tooluniverse-toxicology` (food additive/allergen safety questions) or `tooluniverse-epidemiological-analysis` (dietary-exposure questions) for that.
**LOOK UP, DON'T GUESS**: Never state a nutrient value, ingredient list, allergen, or Nutri-Score from memory — both sources are live and current; query them.
## When to Use This Skill
- "How much [protein/sodium/vitamin C/...] is in [food]?" -> FoodDataCentral
- "What's the full nutrient profile of [generic or USDA reference food]?" -> FoodDataCentral
- "What are the ingredients/allergens in [branded product]?" -> OpenFoodFacts
- "Look up this barcode" -> `OpenFoodFacts_get_product`
- "Find products with/without [additive, allergen, Nutri-Score grade, label]" -> `OpenFoodFacts_filter_products_by_tags`
