1. Purine data: USDA Purine Database 2025 - Table 2 (International) Evidence tier: Peer-reviewed literature Replication: 1 sample International literature sources
2. Fructose data: Biochemical derivation Evidence tier: Estimated

Source details
Biochemically derived value: (1) Distilled spirits contain no purines post-distillation; all nitrogen compounds are removed in the still. (2) Animal muscle tissue contains no fructose; mammalian/avian/fish cells do not synthesise or store fructose. Source: standard biochemistry references.

Values are per 100g unless a note says otherwise, rounded to three significant figures; per-serving figures are calculated from the unrounded measurement, so recomputing from the rounded number can differ by a milligram or so. A single determination is normal in food composition tables, not a defect. Last reviewed July 18, 2026.

How we grade foods

Grades combine purine and fructose data with known gout triggers and benefits. We show our confidence on every food.
