The editorial read

The useful answer has a weight, a composition, and an identity

Portion: the cited record reports about 82 calories for USDA reference amount at 85 grams. On a fixed-weight basis, the same record contains 97 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.

Composition: that source amount also reports 17.8 g protein, 0 g fiber, and 455 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.

Identity: the largest listed formulation input is crustaceans, lobster, northern, raw, representing 100% of the record’s listed input weight. 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 49–194 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 2706349: “Lobster.” 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 2706349, each row multiplies the published per-100-gram values by its stated weight. “1 claw” through “1 lobster” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.

The comparison set contains 30 exact records in the Shellfish USDA category. Here, “middle half” describes FDC 2706349’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 2706349’s 85 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Magnesium; 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.

Strength-side signals

Magnesium41 mg

≈ 10% DV. This does not cross the FDA’s 20% ‘high’ guide.

Calcium90 mg

04 · Highest-impact checks

The three levers most worth resolving first

For “Lobster,” the first-pass checks follow the evidence actually published: its named weights, the absence of a qualifying close alternative, and its source-formulation identity.

  1. 01

    Listed portion span: 1 claw to 1 lobster

    USDA assigns those measures 50 g and 200 g. At this record’s fixed composition, scaled energy moves from 49 kcal to 194 kcal.

  2. 02

    Record identity: FDC 2706349

    No second entry passed the close-record rule for this page. Keep the exact USDA description “Lobster” attached to any value copied from this profile.

  3. 03

    Single listed source: Crustaceans, lobster, northern, raw

    USDA derives this record from one listed source-input row at 100 g. Real preparations can still differ in water, cooking state, brand, and served weight.

05 · Exact-record choice

Select by literal evidence, not the shortest name

Use this profile only when “Lobster” is the closest available description and the 85 g reference can be scaled to the amount you mean.

How to compare FDC 2706349: its source amount is 85 g; every 100-gram column removes portion size from the record-to-record comparison. Neither denominator determines your plate’s weight or recipe.

Inside the source record

Source formulation behind this USDA record

USDA links FDC 2706349 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Lobster” inspectable beside similarly named records.

How to read this

A single-source formulation

Crustaceans, lobster, northern, raw is the only listed source input for this record. That does not mean every real-world version is identical; brands, preparation, water content, and portion weight can still differ.

100 g total listed input weight across the formulation.

Use this formulation to choose a closer record—not to reverse-engineer a recipe. If your meal adds, removes, or substantially changes one of these components, another source entry or a photo-based estimate may fit better.

Exact-record context

What makes this USDA record distinct?

For FDC 2706349, the close-record rule searches the USDA “Shellfish” 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.

No forced match

This record does not have a sufficiently close direct comparator in the published corpus.

No other published “Shellfish” entry shares enough description or exact source-input evidence with FDC 2706349 to clear Feast’s close-record rule. A broad category neighbor would look relevant without establishing a defensible pair.

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 “Lobster,” resolve portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.

  1. 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.

  2. 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.

  3. 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.

  4. 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 2706349 comes from FoodData Central Survey Foods (FNDDS). Its 97 kcal per 100 g becomes 82 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: 2706349

FNDDS food code: 26311110

The scaling for FDC 2706349 can be exact while the match to “Lobster” is wrong. That is why this profile keeps its 85 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
