Compare all 5 food records, nutrition tables and USDA sources

The 5 exact records in this guide report 241–247 calories in the records' own listed source servings and 535–549 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 Corn chips, begin by separating “Corn chips, flavored” from “Corn chips, 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 5 named USDA records in view: 5 direct matches. All sit within “Tortilla, corn, other chips.” 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 5 records together under the exact grouping key “corn chips.” That rule determines membership before any nutrition result is read.

For Corn chips, this page can compare 5 named records from FDC 2708197 through FDC 2708205. 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 45 g comparison anchor

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

Composition

14 kcal separates the fixed-weight endpoints

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

Discriminator

522 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “reduced sodium” (295 mg) and “plain” (817 mg).

Observed source examples

Three landmarks inside this source set—not universal endpoints

These 5 records each use a 45 g serving. Their serving calories compare equal weights within this set. They do not define a calorie range for every corn chips; match the preparation and adjust to your portion.

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

Full comparison

Compare every selected FNDDS record

For Corn chips, 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 45-gram source amount, so serving-weight differences do not explain the calorie spread inside this set. Their own source servings run from 241 calories for “plain” to 247 for “reduced sodium.” At a fixed 100 grams, “plain” is 535 calories and “reduced sodium” is 549—a fixed-weight separation of 14 calories. For Corn chips, 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 “flavored”, “flavored (Fritos)”, “plain”, “plain (Fritos)”, and “reduced sodium”. Across the source formulations, the shared backbone includes snacks, corn-based, extruded, chips, plain; differentiating rows include oil, corn, salt, table, and snacks, tortilla chips, low fat, unsalted. On this Corn chips 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 “Corn chips” cannot resolve the differences between Corn chips, flavored and Corn chips, 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 45 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 “flavored”, “flavored (Fritos)”, “plain”, “plain (Fritos)”, and “reduced sodium”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    Shared source rows include snacks, corn-based, extruded, chips, plain; rows that vary across the set include oil, corn, salt, table, and snacks, tortilla chips, low fat, unsalted. Presence is inspectable evidence, not proof of nutrient causation.

  4. 04

    The unresolved plate

    Even “Corn chips, flavored” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Corn chips 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 corn chips is the right meal family. Then resolve the phrases that actually separate this set—“flavored”, “flavored (Fritos)”, “plain (Fritos)”, 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 Corn chips 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 5 exact records behind Corn chips 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

Corn chips, plain is higher in sodium per 100 g

Corn chips, plain reports 817 mg versus 295 mg for Corn chips, reduced sodium: a 522 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

These listed servings have equal weights

5 listed servings each weigh 45 g

The 5 records with a listed serving weight on this page each use 45 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

Corn chips, plain and Corn chips, 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.
