The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 265 calories for 1 cup at 245 grams. On a fixed-weight basis, the same record contains 108 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 13.4 g protein, 2.7 g fiber, and 926 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is onions, cooked, as ingredient, representing 39.6% of the record’s listed input weight. The record contains 7 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 cup 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 265–567 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 2710108: “Soup, French onion.” 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 2710108, each row multiplies the published per-100-gram values by its stated weight. “1 cup” through “1 can” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 cupUSDA-listed household measure | 245 g | 265 kcal | 13.4 g | 2.7 g | 926 mg |
| 1 individual containerUSDA-listed household measure | 440 g | 475 kcal | 24 g | 4.8 g | 1,663 mg |

04 · Highest-impact checks
The three levers most worth resolving first
For “Soup, French onion,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709556 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 cup to 1 can
USDA assigns those measures 245 g and 525 g. At this record’s fixed composition, scaled energy moves from 265 kcal to 567 kcal.
- 02
Record choice: compare with FDC 2709556
At an equal 100 g, this record has 3.9 g more protein than “Soup, potato.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Onions, cooked, as ingredient
The source formulation has 7 input rows; Onions, cooked, as ingredient supplies 39.6% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “French onion” fits. Inspect FDC 2709556 when “potato” is the more literal description of the food and preparation.

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 bowl size, solid-to-broth ratio, recipe, added cream, oil, or toppings.
For “Soup, French onion,” resolve bowl size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
bowl size
Resolve bowl 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.
- 02
solid-to-broth ratio
Estimate what was actually consumed, including liquid left behind. The same bowl volume can contain a different mass and solid-to-liquid balance.
- 03
recipe
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 04
added cream, oil, or toppings
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2710108 comes from FoodData Central Survey Foods (FNDDS). Its 108 kcal per 100 g becomes 265 kcal at 245 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 cup 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: 2710108
FNDDS food code: 75608100
The scaling for FDC 2710108 can be exact while the match to “Soup, French onion” is wrong. That is why this profile keeps its 245 g weight, 7-row source formulation, and selection uncertainty beside the arithmetic.
