The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 391 calories for 1 regular at 180 grams. On a fixed-weight basis, the same record contains 217 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 18.9 g protein, 3.8 g fiber, and 765 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is tuna salad, made with mayonnaise, representing 66.7% of the record’s listed input weight. The record contains 2 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 regular at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 195–586 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.
Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2707036: “Tuna salad sandwich on wheat.” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.
01 · Portion arithmetic
Three weights, one fixed composition
For FDC 2707036, each row multiplies the published per-100-gram values by its stated weight. “1 miniature/slider” through “1 large” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 miniature/sliderUSDA-listed household measure | 90 g | 195 kcal | 9.5 g | 1.9 g | 383 mg |
| 1 regularUSDA-listed household measure | 180 g | 391 kcal | 18.9 g | 3.8 g | 765 mg |
| 1 largeUSDA-listed household measure | 270 g | 586 kcal | 28.4 g | 5.7 g | 1,148 mg |

04 · Highest-impact checks
The three levers most worth resolving first
For “Tuna salad sandwich on wheat,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707037 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 miniature/slider to 1 large
USDA assigns those measures 90 g and 270 g. At this record’s fixed composition, scaled energy moves from 195 kcal to 586 kcal.
- 02
Record choice: compare with FDC 2707037
At an equal 100 g, this record has 61 mg less sodium than “Tuna salad sandwich on wheat, with cheese.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Tuna salad, made with mayonnaise
The source formulation has 2 input rows; Tuna salad, made with mayonnaise supplies 66.7% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice

Formulation evidence
The listed formulations differ
The formulation rows differ, but the source data do not isolate which component caused any nutrient difference. Input weights describe the standardized formulation—not final plated proportions.
Shared listed inputs: Wheat bread as ingredient in sandwiches; Tuna salad, made with mayonnaise.
Listed only in the comparison: Cheese as ingredient in sandwiches.
Portion evidence
The listed portion sets differ
This record’s reference amount is 180 g; a familiar listed measure is 1 regular (180 g).
The comparison record’s reference amount is 200 g; a familiar listed measure is 1 regular (200 g).
Use the 100-gram row to compare FDC 2707036 with FDC 2707037 at equal mass; use their 180 g and 200 g source amounts only for portion matching.
Evidence boundary: FDC 2707036 versus FDC 2707037 is a comparison of standardized source records—not a measurement of your meal, an overall food-quality rank, or proof that one input caused a difference.

Uncertainty, made actionable
What can change this estimate?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with item size, bread or wrapper size, fillings, sauces and cheese.
For “Tuna salad sandwich on wheat,” resolve item size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
item size
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
- 02
bread or wrapper size
Resolve bread or wrapper size only when the meal or its source gives you evidence. If it is unknown, leave the uncertainty visible instead of choosing the most convenient variant.
- 03
fillings
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
- 04
sauces and cheese
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2707036 comes from FoodData Central Survey Foods (FNDDS). Its 217 kcal per 100 g becomes 391 kcal at 180 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.
About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 regular has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2707036
FNDDS food code: 27550735
The scaling for FDC 2707036 can be exact while the match to “Tuna salad sandwich on wheat” is wrong. That is why this profile keeps its 180 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
