Compare all 2 food records, nutrition tables and USDA sources

The 2 exact records in this guide report 139–157 calories in the records' own listed source servings and 348–376 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 Breakfast bar, begin by separating “Breakfast bar, cereal crust with fruit filling, lowfat” from “Breakfast bar, date, with yogurt coating.” 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 “Cereal bars.” 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 “breakfast bar.” That rule determines membership before any nutrition result is read.

For Breakfast bar, this page can compare 2 named records from FDC 2708116 through FDC 2708115. 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

37–45 g before composition

The largest source amount is 1.2× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

28 kcal separates the fixed-weight endpoints

The lower endpoint is “date; with yogurt coating”; the higher is “cereal crust with fruit filling; lowfat.” This isolates density, not ingredient causation.

Discriminator

2.5 g fiber gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “cereal crust with fruit filling; lowfat” (2.1 g) and “date; with yogurt coating” (4.6 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 breakfast bar.

Important: “Lower” begins with Breakfast bar, cereal crust with fruit filling, lowfat; “higher” ends with Breakfast bar, date, with yogurt coating, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every breakfast bar meal.

Full comparison

Compare every selected FNDDS record

For Breakfast bar, 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 37 to 45 grams—a 8-gram gap before composition enters the comparison. Their own source servings run from 139 calories for “cereal crust with fruit filling; lowfat” to 157 for “date; with yogurt coating.” At a fixed 100 grams, “date; with yogurt coating” is 348 calories and “cereal crust with fruit filling; lowfat” is 376—a fixed-weight separation of 28 calories. For Breakfast bar, 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 “cereal crust with fruit filling, lowfat” and “date, with yogurt coating”. The source formulations contain 2 distinct ingredient codes; examples that appear in only part of the set include breakfast bar, corn flake crust with fruit and cookies, fig bars. On this Breakfast bar 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 “Breakfast bar” cannot resolve the differences between Breakfast bar, cereal crust with fruit filling, lowfat and Breakfast bar, date, with yogurt coating. 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 37–45 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 “cereal crust with fruit filling, lowfat” and “date, with yogurt coating”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    2 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 “Breakfast bar, cereal crust with fruit filling, lowfat” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Breakfast bar 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 breakfast bar is the right meal family. Then resolve the phrases that actually separate this set—“cereal crust with fruit filling, lowfat” and “date, with yogurt coating”—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 Breakfast bar 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.
