Lettuce calories and nutrition: 10 USDA records compared
The 10 exact records in this guide report 2–70 calories in the records' own listed source servings and 18–91 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.
What this page compares
Named source records, not one universal meal
This page includes every selected Feast nutrition record whose normalized USDA description begins with “Lettuce” under the documented one-segment family rule. The records fall within Lettuce and lettuce salads and Vegetables on a sandwich. Exact descriptions remain visible so this grouping does not erase preparation, ingredient, or source-serving differences.
How this guide was assembled: Feast deterministically grouped exact USDA FNDDS records by their source descriptions. Every nutrient number is computed from the linked source fields; this page does not use generated or invented nutrition estimates.
Every number on this page comes from the exact linked record. Values are descriptive observations from the selected records; they are not personalized estimates, recommended portions, or measurements of a meal in front of you.

Serving values preserve each record's listed amount. Per-100-gram calories provide a shared weight basis. Dashes indicate that a value is not available, not that the nutrient is absent.

Portion analysis
Serving total and calorie density answer different questions
The listed source amounts span 8–88 grams, a 11.0× difference in mass before recipe or preparation is considered. Within the selected set, the source servings report 2–70 calories in the records' own listed source servings; the fixed-weight view reports 18–91 calories per 100 grams. A serving total and a per-100-gram value answer different questions, so neither should be substituted for the amount actually eaten.
To scale a record, divide the eaten grams by the record's source grams and multiply the listed serving values by that ratio. This assumes the eaten meal has the same composition as the matched record.
Preparation analysis
The dish name leaves ingredients unresolved
The record names distinguish salad with egg, arugula, boston, for use on a sandwich, and raw. USDA formulation rows also identify 18 distinct source-input codes across the set, including celery, raw, cucumber, with peel, raw, mixed salad greens, raw, and carrots, mature, raw. These details can help select a closer record, but they do not isolate the cause of a nutrient difference or reconstruct a recipe.
A precise-looking result is only as specific as the record match and the portion information supporting it.
What changes the comparison
Four drivers worth checking before choosing a record
The visible dish name is a starting point. These details usually explain more of the variation in the selected source records.
- 01
Source-serving weight
The exact records list 8–88 grams, so serving totals can move even before composition is compared.
- 02
Named source variant
The set explicitly distinguishes salad with egg, arugula, boston, for use on a sandwich, and raw; those words identify different records rather than optional SEO phrasing.
- 03
Nutrient profile
Across each record's own source serving, the displayed data span protein 0.1–3.8 g, fiber 0.1–2.3 g, sodium 2–112 mg. Different serving weights remain visible beside those values.
- 04
Formulation evidence
The source rows include 18 distinct input codes across this set. Input presence and weight describe standardized source formulations, not final plated proportions.
Record matching
How to find the closest description
Begin with the full source description rather than the shortest dish name. Check whether the named form—such as salad with egg, arugula, boston, for use on a sandwich, and raw—matches the meal, then compare the listed source weight with the portion actually eaten. If the brand, recipe, toppings, cooking fat, or portion is known, keep that information with the estimate instead of assuming the generic record already includes it.
A practical matching checklist
- Read the complete lettuce source description, including preparation and additions.
- Compare the listed source weight with the amount actually eaten.
- Prefer a current package or restaurant source when a specific branded item is known.
- Record toppings, sauces, cooking fat, sides, and substitutions that the selected description does not name.
