The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 96 calories for USDA reference amount at 125 grams. On a fixed-weight basis, the same record contains 77 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.7 g protein, 1.3 g fiber, and 251 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is beverages, water, tap, drinking, representing 55.1% of the record’s listed input weight. The record contains 5 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and 1 cup answer different portion questions. Their values are scaled independently from the same per-100-gram source record.
The household measures attached to this record span roughly 96–193 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 2709502: “Potato, mashed, from school lunch.” 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 2709502, each row multiplies the published per-100-gram values by its stated weight. “75% of the reference weight” through “1 cup” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 75% of the reference weightArithmetic scenario from the reference weight | 93.8 g | 72 kcal | 2 g | 0.9 g | 188 mg |
| USDA reference amountExact record reference weight | 125 g | 96 kcal | 2.7 g | 1.3 g | 251 mg |
| 1 cupUSDA-listed household measure | 250 g | 193 kcal | 5.4 g | 2.5 g | 503 mg |
02 · Fixed-weight context
Where 100 grams sits inside Mashed potatoes and white potato mixtures
The comparison set contains 41 exact records in the Mashed potatoes and white potato mixtures USDA category. Here, “lower quarter” describes FDC 2709502’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2709502’s 125 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Vitamin C; the larger tradeoff-side percentage is Sodium. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.

04 · Highest-impact checks
The three levers most worth resolving first
For “Potato, mashed, from school lunch,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709496 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 125 g
A 25% weight move in either direction spans 93.8–156.3 g. When composition is held constant, those endpoints calculate to 72 kcal and 120 kcal.
- 02
Record choice: compare with FDC 2709496
At an equal 100 g, this record has 2.2 g less total fat than “Potato, mashed, from fresh, made with milk.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Beverages, water, tap, drinking
The source formulation has 5 input rows; Beverages, water, tap, drinking supplies 55.1% 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 “mashed; from school lunch” fits. Inspect FDC 2709496 when “mashed; from fresh; made with milk” 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 portion size, raw versus cooked weight, cooking method, added fat or sauce.
For “Potato, mashed, from school lunch,” resolve portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
portion 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
raw versus cooked weight
Match the food state before matching the number. Cooking, draining, or added liquid can change grams and concentration even when the food name barely changes.
- 03
cooking method
Match the method named by the source—such as baked, fried, boiled, or grilled—before scaling. Preparation can change both water content and the ingredients retained in the finished food.
- 04
added fat or sauce
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 2709502 comes from FoodData Central Survey Foods (FNDDS). Its 77 kcal per 100 g becomes 96 kcal at 125 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.” We display it as a USDA reference amount because it is a database comparison point—not a suggested portion or a claim about what most people should eat.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2709502
FNDDS food code: 71501018
The scaling for FDC 2709502 can be exact while the match to “Potato, mashed, from school lunch” is wrong. That is why this profile keeps its 125 g weight, 5-row source formulation, and selection uncertainty beside the arithmetic.
