Compare all 3 food records, nutrition tables and USDA sources

The 3 exact records in this guide report 16–33 calories in the records' own listed source servings and 24–51 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 Spaghetti sauce, begin by separating “Spaghetti sauce” from “Spaghetti sauce, reduced sodium.” 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 3 named USDA records in view: 3 direct matches. All sit within “Pasta sauces, tomato-based.” 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 3 records together under the exact grouping key “spaghetti sauce.” That rule determines membership before any nutrition result is read.

For Spaghetti sauce, this page can compare 3 named records from FDC 2709745 through FDC 2709747. 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 65 g comparison anchor

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

Composition

27 kcal separates the fixed-weight endpoints

The lower endpoint is “fat free”; the higher is “reduced sodium.” This isolates density, not ingredient causation.

Discriminator

444 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “reduced sodium” (30 mg) and “fat free” (474 mg).

Observed source examples

Three landmarks inside this source set—not universal endpoints

These 3 records each use a 65 g serving. Their serving calories compare equal weights within this set. They do not define a calorie range for every spaghetti sauce; match the preparation and adjust to your portion.

Important: “Lower” begins with Spaghetti sauce, fat free; “higher” ends with Spaghetti sauce, reduced sodium, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every spaghetti sauce meal.

Full comparison

Compare every selected FNDDS record

For Spaghetti sauce, 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 65-gram source amount, so serving-weight differences do not explain the calorie spread inside this set. Their own source servings run from 16 calories for “fat free” to 33 for “reduced sodium.” At a fixed 100 grams, “fat free” is 24 calories and “reduced sodium” is 51—a fixed-weight separation of 27 calories. For Spaghetti sauce, 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 “Spaghetti sauce”, “fat free”, and “reduced sodium”. The source formulations contain 3 distinct ingredient codes; examples that appear in only part of the set include sauce, pasta, spaghetti/marinara, ready-to-serve, sauce, pasta, spaghetti/marinara, ready-to-serve, low sodium, and tomato products, canned, sauce. On this Spaghetti sauce 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 “Spaghetti sauce” cannot resolve the differences between Spaghetti sauce and Spaghetti sauce, reduced sodium. 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 65 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 “Spaghetti sauce”, “fat free”, and “reduced sodium”. 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 “Spaghetti sauce” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Spaghetti sauce 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 spaghetti sauce is the right meal family. Then resolve the phrases that actually separate this set—“Spaghetti sauce”, “fat free”, and “reduced sodium”—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 Spaghetti sauce 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 Spaghetti sauce 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

Spaghetti sauce, fat free is higher in sodium per 100 g

Spaghetti sauce, fat free reports 474 mg versus 30 mg for Spaghetti sauce, reduced sodium: a 444 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

These listed servings have equal weights

3 listed servings each weigh 65 g

The 3 records with a listed serving weight on this page each use 65 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

Spaghetti sauce, fat free and Spaghetti sauce, reduced sodium are not interchangeable

The page keeps both records at the same 100 g denominator and makes Sodium wording (No matching controlled term in the source name versus reduced- or low-sodium wording) 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.
