Compare all 2 food records, nutrition tables and USDA sources

The 2 exact records in this guide report 187–198 calories in the records' own listed source servings and 287–330 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 Cornbread, begin by separating “Cornbread, made from home recipe” from “Cornbread, prepared from mix.” 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 2 named USDA records in view: 2 direct matches. All sit within “Biscuits, muffins, quick breads.” 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 2 records together under the exact grouping key “cornbread.” That rule determines membership before any nutrition result is read.

For Cornbread, this page can compare 2 named records from FDC 2707811 through FDC 2707810. 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

60–65 g before composition

The largest source amount is 1.1× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

43 kcal separates the fixed-weight endpoints

The lower endpoint is “made from home recipe”; the higher is “prepared from mix.” This isolates density, not ingredient causation.

Discriminator

0.8 g fiber gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “made from home recipe” (1.5 g) and “prepared from mix” (2.3 g).

Observed source examples

Both records, with their own serving weights intact

The cards are ordered by calories in each record's listed serving. Serving weights differ, so use per-100-gram values to compare composition. These selected records do not define a calorie range for every cornbread.

Important: “Lower” begins with Cornbread, made from home recipe; “higher” ends with Cornbread, prepared from mix, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every cornbread meal.

Full comparison

Compare every selected FNDDS record

For Cornbread, 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

The listed source amounts run from 60 to 65 grams—a 5-gram gap before composition enters the comparison. Their own source servings run from 187 calories for “made from home recipe” to 198 for “prepared from mix.” At a fixed 100 grams, “made from home recipe” is 287 calories and “prepared from mix” is 330—a fixed-weight separation of 43 calories. For Cornbread, 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 “made from home recipe” and “prepared from mix”. The source formulations contain 9 distinct ingredient codes; examples that appear in only part of the set include bread, cornbread, dry mix, prepared with 2% milk, 80% margarine, and eggs, cornmeal, degermed, enriched, yellow, eggs, grade a, large, egg whole, and flour, wheat, all-purpose, enriched, bleached. On this Cornbread 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 “Cornbread” cannot resolve the differences between Cornbread, made from home recipe and Cornbread, prepared from mix. The four checks below identify the record wording, source weight, and formulation evidence that can.

  1. 01

    Source weight before serving calories

    The source amounts span 60–65 grams. Compare per 100 grams before reading a serving-calorie gap as a composition gap.

  2. 02

    The words that split the family

    Representative record-level distinctions include “made from home recipe” and “prepared from mix”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    9 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 “Cornbread, made from home recipe” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Cornbread 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 cornbread is the right meal family. Then resolve the phrases that actually separate this set—“made from home recipe” and “prepared from mix”—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 Cornbread 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 2 exact records behind Cornbread 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

Cornbread, made from home recipe is higher in vitamin D per 100 g

Cornbread, made from home recipe reports 0.7 µg versus 0 µg for Cornbread, prepared from mix: a 0.7 µg difference when both are normalized to 100 g.

Inspect the underlying evidence

The denominator changes the answer

Cornbread, prepared from mix is denser; Cornbread, made from home recipe is higher in its source amount

Cornbread, prepared from mix reports 6.6 g per 100 g and 4 g in USDA source amount (60 g). Cornbread, made from home recipe reports a lower 6.6 g per 100 g but a higher 4.3 g in USDA source amount (65 g).

Record identity is part of the estimate

Distinguish “Cornbread, made from home recipe” from “Cornbread, prepared from mix”

These are separate USDA records with separate formulations or survey descriptions. Match preparation, additions, and the named household amount before borrowing either record’s nutrients.
