Every tracked menu scored on nutrient density using USDA data — not opinion, not a dietitian's shortlist.
We track 266 items across 13 chains. 172 carry a complete USDA nutrient panel and are scored on NRF9.3, the academic nutrient-density index — nine nutrients to encourage against three to limit, normalised per 100 kcal so a large item cannot win by being large. Of those, 20 score below zero: their sodium, saturated fat, and sugar outweigh everything they supply. 121 items are single-serving meals rather than sauces, sides, or family packs, which is the distinction most rankings of this kind quietly skip.
