Compare all 4 food records, nutrition tables and USDA sources

The 4 exact records in this guide report 191–211 calories in the records' own listed source servings and 681–754 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.

Match my meal

Start with the description closest to what you ate

For Pecans, begin by separating “Pecans, honey roasted” from “Pecans, unsalted.” Choosing a card filters this source set; it does not infer the portion or fill in ingredients the chosen description does not name.

What this page compares

Named source records, not one universal meal

This guide keeps 4 named USDA records in view: 4 direct matches. All sit within “Nuts and seeds.” The exact descriptions remain the unit of comparison; the familiar heading is only the doorway into the evidence.

Why these records appear together: The deterministic grouping rule “normalized first description segment” placed these 4 records together under the exact grouping key “pecans.” That rule determines membership before any nutrition result is read.

For Pecans, this page can compare 4 named records from FDC 2707525 through FDC 2707524. It cannot observe which preparation was eaten, recover unnamed additions, or supply the eaten grams.

Editor’s decision brief

The three facts to carry into the table

Carry the denominator, exact identity, and strongest observed contrast into every number below.

Portion

A shared 28 g comparison anchor

Equal source weights make the selected Pecans serving totals easier to compare, but the eaten portion still has to be measured or estimated.

Composition

73 kcal separates the fixed-weight endpoints

The lower endpoint is “honey roasted”; the higher is “unsalted.” This isolates density, not ingredient causation.

Discriminator

383 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “unroasted” (0 mg) and “salted” (383 mg).

Observed source examples

Three landmarks inside this source set—not universal endpoints

These 4 records each use a 28 g serving. Their serving calories compare equal weights within this set. They do not define a calorie range for every pecans; match the preparation and adjust to your portion.

Important: “Lower” begins with Pecans, honey roasted; “higher” ends with Pecans, unsalted, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every pecans meal.

Full comparison

Compare every selected FNDDS record

For Pecans, serving columns preserve each record’s own listed amount, while calories per 100 g hold weight constant. A dash means the cited record does not supply that field; it does not mean the nutrient is absent.

On smaller screens, focus the table and scroll horizontally to read every column.

Portion analysis

Serving total and calorie density answer different questions

Every selected record uses a 28-gram source amount, so serving-weight differences do not explain the calorie spread inside this set. Their own source servings run from 191 calories for “honey roasted” to 211 for “unsalted.” At a fixed 100 grams, “honey roasted” is 681 calories and “unsalted” is 754—a fixed-weight separation of 73 calories. For Pecans, the serving view answers “how much is in the database portion?”; the 100-gram view answers “how concentrated is the matched record?” Neither reveals how many grams were actually eaten.

The scaling rule: multiply a per-100-gram value by eaten grams ÷ 100. The arithmetic is exact; the result is only as defensible as the record match and portion estimate.

Preparation analysis

The long description carries the evidence

The published descriptions distinguish forms such as “honey roasted”, “salted”, “unroasted”, and “unsalted”. Across the source formulations, the shared backbone includes nuts, pecans, halves, raw; differentiating rows include vegetable oil, nfs, salt, table, and sugars, granulated. On this Pecans page, those rows make the records inspectable, but they are not a controlled experiment: they cannot tell us that one named input, by itself, caused a nutrient difference.

Database precision is not meal certainty. Retain the exact description beside the number so later corrections remain possible.

What changes the comparison

Four drivers worth checking before choosing a record

The family label “Pecans” cannot resolve the differences between Pecans, honey roasted and Pecans, unsalted. The four checks below identify the record wording, source weight, and formulation evidence that can.

  1. 01

    A shared source weight

    Every selected record uses 28 grams. Inside this set, serving-calorie differences therefore reflect the published composition rather than a change in source weight.

  2. 02

    The words that split the family

    Representative record-level distinctions include “honey roasted”, “salted”, “unroasted”, and “unsalted”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    Shared source rows include nuts, pecans, halves, raw; rows that vary across the set include vegetable oil, nfs, salt, table, and sugars, granulated. Presence is inspectable evidence, not proof of nutrient causation.

  4. 04

    The unresolved plate

    Even “Pecans, honey roasted” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Pecans unknowns for correction instead of converting them into false precision.

Record matching

Match identity first; scale quantity second

Read the source name as a sequence of decisions. First confirm that pecans is the right meal family. Then resolve the phrases that actually separate this set—“honey roasted”, “salted”, “unroasted”, and “unsalted”—before comparing gram weight. If a package, menu, or known recipe provides a closer first-party description, prefer it and keep this USDA record as a transparent fallback.

A practical matching checklist

  1. Read the complete Pecans source description, including preparation and additions.
  2. Compare the listed source weight with the amount actually eaten.
  3. Prefer a current package or restaurant source when a specific branded item is known.
  4. Record toppings, sauces, cooking fat, sides, and substitutions that the selected description does not name.

Decision support from the exact records on this page

Turn source data into a better next decision

These conclusions and reading paths are computed from 4 exact records behind Pecans source-record guide. Links are chosen by record identity, controlled contrast, formulation input, nutrient spread, or serving context—not by loose keyword similarity.

Equal-weight result

Pecans, salted is higher in sodium per 100 g

Pecans, salted reports 383 mg versus 0 mg for Pecans, unroasted: a 383 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

These listed servings have equal weights

4 listed servings each weigh 28 g

The 4 records with a listed serving weight on this page each use 28 g. Their serving totals therefore compare equal weights, even if the household labels differ. Match the preparation and adjust the weight to the amount you eat.

Choose the record before reading the number

Pecans, salted and Pecans, unsalted are not interchangeable

The page keeps both records at the same 100 g denominator and makes Sodium wording (salted versus unsalted) the explicit record-description contrast. It does not show that the wording difference caused a nutrient difference. Pick the description that matches the food in front of you rather than averaging away the distinction.
