The editorial read

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

Portion: the cited record reports about 163 calories for USDA reference amount at 28 grams. On a fixed-weight basis, the same record contains 582 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.

Composition: that source amount also reports 5.7 g protein, 2.8 g fiber, and 2 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.

Identity: the largest listed formulation input is nuts, pistachio nuts, dry roasted, without salt added, representing 97% of the record’s listed input weight. The record contains 2 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.

The reference amount and 1 cup, in shell, yields 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 3–745 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 2707530: “Pistachio nuts, unsalted.” 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 2707530, each row multiplies the published per-100-gram values by its stated weight. “1 nut” through “1 cup, without shell” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.

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, preparation, added fat, sauce or seasoning.

For “Pistachio nuts, unsalted,” 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

    preparation

    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.

  3. 03

    added 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.

  4. 04

    sauce or seasoning

    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 2707530 comes from FoodData Central Survey Foods (FNDDS). Its 582 kcal per 100 g becomes 163 kcal at 28 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: 2707530

FNDDS food code: 42114145

The scaling for FDC 2707530 can be exact while the match to “Pistachio nuts, unsalted” is wrong. That is why this profile keeps its 28 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
