Compare all 3 food records, nutrition tables and USDA sources

The 3 exact records in this guide report 164–164 calories in the records' own listed source servings and 584–587 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.

What this page compares

Named source records, not one universal meal

This guide keeps 3 named USDA records in view: 3 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 two description segments” placed these 3 records together under the exact grouping key “peanuts dry roasted.” That rule determines membership before any nutrition result is read.

For Peanuts, dry roasted, this page can compare 3 named records from FDC 2707518 through FDC 2707519. 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 Peanuts, dry roasted serving totals easier to compare, but the eaten portion still has to be measured or estimated.

Composition

3 kcal separates the fixed-weight endpoints

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

Discriminator

404 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “unsalted” (6 mg) and “salted” (410 mg).

Observed source examples

Three landmarks inside this source set—not universal endpoints

These 3 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 peanuts, dry roasted; match the preparation and adjust to your portion.

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

Full comparison

Compare every selected FNDDS record

For Peanuts, dry roasted, 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.

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 164 calories for “lightly salted” to 164 for “unsalted.” At a fixed 100 grams, “lightly salted” is 584 calories and “unsalted” is 587—a fixed-weight separation of 3 calories. For Peanuts, dry roasted, 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 “dry roasted, lightly salted”, “dry roasted, salted”, and “dry roasted, unsalted”. The source formulations contain 3 distinct ingredient codes; examples that appear in only part of the set include peanuts, all types, dry-roasted, without salt, peanuts, all types, dry-roasted, with salt, and salt, table. On this Peanuts, dry roasted 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 “Peanuts, dry roasted” cannot resolve the differences between Peanuts, dry roasted, lightly salted and Peanuts, dry roasted, 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 “dry roasted, lightly salted”, “dry roasted, salted”, and “dry roasted, unsalted”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    3 source-input codes appear across the selected records. Their presence and listed weights describe USDA formulations, not finished plated proportions.

  4. 04

    The unresolved plate

    Even “Peanuts, dry roasted, lightly salted” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Peanuts, dry roasted 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 peanuts, dry roasted is the right meal family. Then resolve the phrases that actually separate this set—“dry roasted, lightly salted”, “dry roasted, salted”, and “dry roasted, 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 Peanuts, dry roasted 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 3 exact records behind Peanuts, dry roasted 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

Peanuts, dry roasted, salted is higher in sodium per 100 g

Peanuts, dry roasted, salted reports 410 mg versus 6 mg for Peanuts, dry roasted, unsalted: a 404 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

These listed servings have equal weights

3 listed servings each weigh 28 g

The 3 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

Peanuts, dry roasted, lightly salted and Peanuts, dry roasted, 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.
