US Food Purine Content
How much purine is in each food and drink - the number people managing gout or high uric acid (and the diet apps serving them) actually need, and which exists nowhere as a clean table. USDA and NIH's Office of Dietary Supplements published the analytically-measured Purine Database (Release 2.0, 2025) as a multi-sheet Excel workbook with merged two-row headers and food-group headers interleaved with the data; we parse it into one tidy long table of (food × purine → mg per 100 g). Covers North-American and internationally-sourced foods plus alcoholic beverages, for the four measured purine bases - adenine, guanine, hypoxanthine, xanthine - and their total, each with mean, SEM, min and max. Public domain (U.S. Government work).
