US Food Glucosinolate Content
The glucosinolate content of cruciferous vegetables - the sulphur compounds in broccoli, cabbage, mustard and radish that chemoprevention and nutrition research studies, and that appear in no standard nutrition table. USDA and NIH's Office of Dietary Supplements published the first substantial public dataset as one Excel workbook of very wide tables (a Mean/SD/Min/Max block per compound, ~25 compounds, names on a merged header row); we parse every sheet into one tidy long table of (food × glucosinolate → mg per 100 g fresh weight), with the plant's scientific name. Public domain (U.S. Government work).

Built only from a named, redistributable official source under a documented open licence - not scraped web data. No copyright grey zone, no personal data. Ships machine-readable Croissant metadata (ML Commons - loads in Hugging Face / Kaggle / Google), an AI training-licence manifest documenting source, licence and provenance for your model's data governance, and a machine-readable data dictionary (drop it into an agent / RAG prompt so the model knows every column) - all inspectable before you buy.
What's included
- Glucosinolate content (mg/100 g FW) of cruciferous vegetables - nowhere else as a clean table
- ~25 individual glucosinolates (glucoraphanin, sinigrin, glucobrassicin, …) per food
- Mean, SD, min and max, with the plant's scientific name; tidy long shape
- Audience: chemoprevention / phytochemical / nutrition research, health apps
- Public domain (USDA & NIH Office of Dietary Supplements) - no personal data
