The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 209 calories for 1 medium at 170 grams. On a fixed-weight basis, the same record contains 123 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 3.2 g protein, 2.4 g fiber, and 299 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is potatoes, baked, flesh, without salt, representing 94.9% of the record’s listed input weight. The record contains 3 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 medium 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 74–369 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 2709413: “Potato, roasted, from fresh, peel not eaten, made with butter.” 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 2709413, each row multiplies the published per-100-gram values by its stated weight. “1 baby potato” through “1 large” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 baby potatoUSDA-listed household measure | 60 g | 74 kcal | 1.1 g | 0.8 g | 106 mg |
| 1 mediumUSDA-listed household measure | 170 g | 209 kcal | 3.2 g | 2.4 g | 299 mg |
| 1 largeUSDA-listed household measure | 300 g | 369 kcal | 5.7 g | 4.2 g | 528 mg |
02 · Fixed-weight context

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2709413’s 170 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Vitamin C; the larger tradeoff-side percentage is Saturated fat. 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, roasted, from fresh, peel not eaten, made with butter,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709391 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 baby potato to 1 large
USDA assigns those measures 60 g and 300 g. At this record’s fixed composition, scaled energy moves from 74 kcal to 369 kcal.
- 02
Source identity: FDC 2709413 versus 2709391
The closest published neighbor currently carries the same nutrient, portion, and source-input evidence. The FDC IDs still identify separate source records, so the exact citation remains the deciding field.
- 03
Formulation anchor: Potatoes, baked, flesh, without salt
The source formulation has 3 input rows; Potatoes, baked, flesh, without salt supplies 94.9% 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
The published nutrient, portion, and formulation evidence is identical for this pair. Preserve FDC 2709413 when this is the cited source; do not manufacture a nutritional distinction that the records do not show.

Source-equivalent fields
Different source identities, matching published reference fields
Across the nutrient, portion, and formulation fields published here, FDC 2709413 and FDC 2709391 match exactly. Their descriptions and source identities remain distinct provenance; matching database fields do not make every real-world version interchangeable.
Practical reading: do not infer a nutrient difference from the names alone. Choose the description that more closely matches what was reported, while treating the shared values as a standardized reference rather than a measurement of your plate.
Evidence boundary: FDC 2709413 versus FDC 2709391 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 portion size, raw versus cooked weight, cooking method, added fat or sauce.
For “Potato, roasted, from fresh, peel not eaten, made with butter,” 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 2709413 comes from FoodData Central Survey Foods (FNDDS). Its 123 kcal per 100 g becomes 209 kcal at 170 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 medium 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: 2709413
FNDDS food code: 71104140
The scaling for FDC 2709413 can be exact while the match to “Potato, roasted, from fresh, peel not eaten, made with butter” is wrong. That is why this profile keeps its 170 g weight, 3-row source formulation, and selection uncertainty beside the arithmetic.
