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 Certainty (fructose = 0) Evidence tier: Lab-verified Animal products (meat, seafood, eggs, plain dairy) contain no fructose by biochemical composition.

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.
