The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 114 calories for USDA reference amount at 85 grams. On a fixed-weight basis, the same record contains 134 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 6.5 g protein, 1.6 g fiber, and 366 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is mollusks, oyster, eastern, wild, raw, representing 41.8% 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 reference amount and 1 oyster 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 40–114 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 2706849: “Oysters Rockefeller.” 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 2706849, each row multiplies the published per-100-gram values by its stated weight. “1 oyster” through “USDA reference amount” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 oysterUSDA-listed household measure | 30 g | 40 kcal | 2.3 g | 0.6 g | 129 mg |
| 75% of the reference weightArithmetic scenario from the reference weight | 63.8 g | 85 kcal | 4.9 g | 1.2 g | 274 mg |
| USDA reference amountExact record reference weight | 85 g | 114 kcal | 6.5 g | 1.6 g | 366 mg |

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2706849’s 85 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Vitamin A; 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 “Oysters Rockefeller,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2706564 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 85 g
A 25% weight move in either direction spans 63.8–106.3 g. When composition is held constant, those endpoints calculate to 85 kcal and 142 kcal.
- 02
Record choice: compare with FDC 2706564
At an equal 100 g, this record has 0.9 g more dietary fiber than “Clams Casino.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Mollusks, oyster, eastern, wild, raw
The source formulation has 7 input rows; Mollusks, oyster, eastern, wild, raw supplies 41.8% 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 the exact wording “Oysters Rockefeller” fits. Inspect FDC 2706564 when the exact wording “Clams Casino” 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, species or cut, cooking method, breading, butter, or sauce.
For “Oysters Rockefeller,” 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
species or cut
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 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
breading, butter, 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 2706849 comes from FoodData Central Survey Foods (FNDDS). Its 134 kcal per 100 g becomes 114 kcal at 85 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: 2706849
FNDDS food code: 27450250
The scaling for FDC 2706849 can be exact while the match to “Oysters Rockefeller” is wrong. That is why this profile keeps its 85 g weight, 7-row source formulation, and selection uncertainty beside the arithmetic.
