Data Sources & Methodology
Data source: USDA FoodData Central.
Ranking method: Foods are sorted by the criterion value computed directly from per-100g USDA data. The per-calorie view is computed as criterionPer100g / caloriesPer100g × 100. Tier groupings use equal-interval breaks on the criterion range. No subjective scoring or editorial ranking 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.
