The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 157 calories for 1 egg at 70 grams. On a fixed-weight basis, the same record contains 224 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 8.4 g protein, 0 g fiber, and 185 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is egg, duck, whole, fresh, raw, representing 93.2% 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 egg 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 157–302 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 2707176: “Duck egg, cooked.” 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 2707176, 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 | 52.5 g | 118 kcal | 6.3 g | 0 g | 139 mg |
| 1 eggUSDA-listed household measure | 70 g | 157 kcal | 8.4 g | 0 g | 185 mg |
| 1 cupUSDA-listed household measure | 135 g | 302 kcal | 16.2 g | 0 g | 356 mg |

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2707176’s 70 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Vitamin A; 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 “Duck egg, cooked,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707177 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 egg to 1 cup
USDA assigns those measures 70 g and 135 g. At this record’s fixed composition, scaled energy moves from 157 kcal to 302 kcal.
- 02
Record choice: compare with FDC 2707177
At an equal 100 g, this record has 0.9 g less protein than “Goose egg, cooked.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Egg, duck, whole, fresh, raw
The source formulation has 3 input rows; Egg, duck, whole, fresh, raw supplies 93.2% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice

Exact-record context
What makes this USDA record distinct?
For FDC 2707176, the close-record rule searches the USDA “Eggs and omelets” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

Plain-English read
The six displayed nutrient values are close under a conservative materiality screen. Small differences remain exact source values, not evidence that one food is preferable.
Only this record lists Egg, duck, whole, fresh, raw. Only the comparison record lists Egg, goose, whole, fresh, raw. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
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: Salt, table; Oil or table fat, NFS.
Listed only in this record: Egg, duck, whole, fresh, raw.
Listed only in the comparison: Egg, goose, whole, fresh, raw.
Portion evidence
The listed portion sets differ
This record’s reference amount is 70 g; a familiar listed measure is 1 egg (70 g).
The comparison record’s reference amount is 144 g; a familiar listed measure is 1 egg (144 g).
Use the 100-gram row to compare FDC 2707176 with FDC 2707177 at equal mass; use their 70 g and 144 g source amounts only for portion matching.
Evidence boundary: FDC 2707176 versus FDC 2707177 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, recipe or brand, cooking fat, toppings and add-ins.
For “Duck egg, cooked,” 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
recipe or brand
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
cooking fat
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
- 04
toppings and add-ins
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 2707176 comes from FoodData Central Survey Foods (FNDDS). Its 224 kcal per 100 g becomes 157 kcal at 70 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 egg 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: 2707176
FNDDS food code: 31201000
The scaling for FDC 2707176 can be exact while the match to “Duck egg, cooked” is wrong. That is why this profile keeps its 70 g weight, 3-row source formulation, and selection uncertainty beside the arithmetic.
