The healthiest picks at each
The three highest-scoring menu items (50+ calories) at each chain — a smarter order beats the menu average at either one.
Methodology. Every figure is computed from published nutrition data for 47 Subway items and 51 Jimmy John’s items, current as of June 27, 2026. Each item is graded A–F by the Nom Score, which weighs sodium, saturated fat, sugar, portion size, fiber, and protein per calorie against FDA Daily Values (sodium 2,300 mg).
Per-chain averages span each chain’s entire published menu — entrees, sides, drinks, and desserts — the same full-menu basis as our State of Fast Food Nutrition report, so the numbers reconcile across the site. Because menu mix differs between chains, an average describes a whole menu, not any single order.
We compare published nutrition data only; verdicts are by average Nom Score, not taste. Values may vary by location and over time. Restaurant names and trademarks belong to their owners; Nom is an independent guide.
