The editorial read
Portion: the cited record reports about 210 calories for USDA reference amount at 28 grams. On a fixed-weight basis, the same record contains 750 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.8 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 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 11–750 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
This analysis belongs to USDA FDC 2707522: “Pecans, unroasted.” 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
For FDC 2707522, 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 | 213 kcal | 2.8 g | 1.6 g | 0 mg |
| 1 cupUSDA-listed household measure | 100 g | 750 kcal | 10 g | 5.8 g | 0 mg |
02 · Fixed-weight context
The comparison set contains 68 exact records in the Nuts and seeds USDA category. Here, “upper quarter” describes FDC 2707522’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
At FDC 2707522’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.
Magnesium29 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.
Saturated fat1.8 g
≈ 9% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
For “Pecans, unroasted,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707524 alternative, and its source-formulation identity.
USDA assigns those measures 1.5 g and 100 g. At this record’s fixed composition, scaled energy moves from 11 kcal to 750 kcal.
At an equal 100 g, this record has 0.2 g more dietary fiber than “Pecans, unsalted.” That is a record-level contrast; it does not identify which ingredient caused the difference.
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
Keep this record when “unroasted” fits. Inspect FDC 2707524 when “unsalted” is the more literal description of the food and preparation.

How to compare FDC 2707522: its source amount is 28 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
USDA links FDC 2707522 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Pecans, unroasted” inspectable beside similarly named records.
How to read this
Nuts, pecans, halves, 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.

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 the comparison record lists Vegetable oil, NFS. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
Formulation evidence
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.
Listed only in the comparison: Vegetable oil, NFS.
Portion evidence
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 2707522 with FDC 2707524 at equal mass; use their 28 g and 28 g source amounts only for portion matching.
Evidence boundary: FDC 2707522 versus FDC 2707524 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
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, unroasted,” resolve portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
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.
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
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
FDC 2707522 comes from FoodData Central Survey Foods (FNDDS). Its 750 kcal per 100 g becomes 210 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.

The scaling for FDC 2707522 can be exact while the match to “Pecans, unroasted” is wrong. That is why this profile keeps its 28 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
