Data Sources & Methodology
Data source: USDA FoodData Central.
Comparison method: All macro values are calculated from the same USDA per-100g baseline. Percentage differences are computed as ((foodA − foodB) / foodB) × 100. Winners are determined per individual macro — a food can win on protein and lose on fat simultaneously. No weighting or aggregation is applied.
Accuracy note: Macro values represent averages across measured samples; individual items may vary ±5–10% depending on brand, farming method, and preparation technique. For clinical nutrition, consult a registered dietitian.
Update policy: Macro values are reviewed quarterly against USDA FoodData Central updates. Page last verified: 2026.
