The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 211 calories for USDA reference amount at 28 grams. On a fixed-weight basis, the same record contains 754 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.7 g protein, 1.6 g fiber, and 0 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is nuts, pecans, halves, raw, 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 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 11–754 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 2707524: “Pecans, 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 2707524, each row multiplies the published per-100-gram values by its stated weight. “1 nut” through “1 cup” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 nutUSDA-listed household measure | 1.5 g | 11 kcal | 0.1 g | 0.1 g | 0 mg |
| 1 ozUSDA-listed household measure | 28.4 g | 214 kcal | 2.7 g | 1.6 g | 0 mg |
| 1 cupUSDA-listed household measure | 100 g | 754 kcal | 9.7 g | 5.6 g | 0 mg |
02 · Fixed-weight context
Where 100 grams sits inside Nuts and seeds
The comparison set contains 68 exact records in the Nuts and seeds USDA category. Here, “upper quarter” describes FDC 2707524’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 2707524’s 28 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Magnesium; 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.
Strength-side signals
Magnesium28 mg
≈ 7% DV. This does not cross the FDA’s 20% ‘high’ guide.
Dietary fiber1.6 g
≈ 6% DV. This does not cross the FDA’s 20% ‘high’ guide.
Tradeoff-side signals
Saturated fat1.9 g
≈ 9% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Pecans, unsalted,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707523 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 nut to 1 cup
USDA assigns those measures 1.5 g and 100 g. At this record’s fixed composition, scaled energy moves from 11 kcal to 754 kcal.
- 02
Record choice: compare with FDC 2707523
At an equal 100 g, this record has 383 mg less sodium than “Pecans, salted.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Nuts, pecans, halves, raw
The source formulation has 2 input rows; Nuts, pecans, halves, raw supplies 97% 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 “unsalted” fits. Inspect FDC 2707523 when “salted” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2707524 to 2 source inputs totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Pecans, unsalted” inspectable beside similarly named records.
How to read this
2 listed components
The largest listed inputs by source weight are Nuts, pecans, halves, raw, Vegetable oil, NFS. The order and weights below come from the standardized USDA formulation, so they offer context for this exact database entry.

USDA shorthand in this evidence
- NFS means “not further specified.” The record intentionally leaves the exact subtype, size, or preparation unresolved.
Exact-record context
What makes this USDA record distinct?
For FDC 2707524, the close-record rule searches the USDA “Nuts and seeds” 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
At the fixed 100-gram basis, this record lists 383 mg less sodium than “Pecans, salted.”
Only the comparison record lists Salt, table. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
1 of the six displayed differences clears the documented materiality screen. It is a reading aid, not a health rating.
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: Nuts, pecans, halves, raw; Vegetable oil, NFS.
Listed only in the comparison: Salt, table.
Portion evidence
The listed portion sets match
This record’s reference amount is 28 g; a familiar listed measure is 1 cup (100 g).
The comparison record’s reference amount is 28 g; a familiar listed measure is 1 cup (100 g).
Use the 100-gram row to compare FDC 2707524 with FDC 2707523 at equal mass; use their 28 g and 28 g source amounts only for portion matching.
Evidence boundary: FDC 2707524 versus FDC 2707523 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, preparation, added fat, sauce or seasoning.
For “Pecans, unsalted,” 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
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.
- 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.
- 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 2707524 comes from FoodData Central Survey Foods (FNDDS). Its 754 kcal per 100 g becomes 211 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: 2707524
FNDDS food code: 42112210
The scaling for FDC 2707524 can be exact while the match to “Pecans, unsalted” is wrong. That is why this profile keeps its 28 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
