Bread calories per large or thick slice: 81–263 across 79 of 103 named USDA examples

Across 79 of 103 named USDA examples, a large or thick slice contains 81–263 calories. Their listed weights span 27–96 g, so each calorie value is calculated from that example's own gram weight and published calories per 100 g. The remaining 24 specifically named examples do not list that exact household measure.

Compare all 103 food records, nutrition tables and USDA sources

The 103 exact records in this guide report 49–296 calories in the records' own listed source servings and 188–448 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 Bread, begin by separating “Bread, barley” from “Bread, zucchini.” 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 103 named USDA records in view: 103 direct matches. They span 3 source categories, including Yeast breads, Biscuits, muffins, quick breads, and Doughnuts, sweet rolls, pastries. 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 103 records together under the exact grouping key “bread.” That rule determines membership before any nutrition result is read.

For Bread, this page can compare 103 named records from FDC 2707788 through FDC 2707851. 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

18–85 g before composition

The largest source amount is 4.7× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

260 kcal separates the fixed-weight endpoints

The lower endpoint is “sprouted wheat”; the higher is “cheese, toasted.” This isolates density, not ingredient causation.

Discriminator

809 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “Spanish coffee” (15 mg) and “cheese, toasted” (824 mg).

Observed source examples

Three landmarks inside this source set—not universal endpoints

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 bread.

Important: “Lower” begins with Bread, sprouted wheat; “higher” ends with Bread, Spanish coffee, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every bread meal.

Full comparison

Compare every selected FNDDS record

For Bread, 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 18 to 85 grams—a 67-gram gap before composition enters the comparison. Their own source servings run from 49 calories for “sprouted wheat” to 296 for “Spanish coffee.” At a fixed 100 grams, “sprouted wheat” is 188 calories and “cheese, toasted” is 448—a fixed-weight separation of 260 calories. For Bread, 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 “barley”, “Italian, Grecian, Armenian”, “pita, wheat or cracked wheat”, “vegetable, toasted”, and “zucchini”. The source formulations contain 84 distinct ingredient codes; examples that appear in only part of the set include salt, table, sugars, granulated, milk, nfs, and beverages, water, tap, drinking. On this Bread 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 “Bread” cannot resolve the differences between Bread, barley and Bread, zucchini. 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 18–85 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 “barley”, “Italian, Grecian, Armenian”, “pita, wheat or cracked wheat”, “vegetable, toasted”, and “zucchini”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    84 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 “Bread, barley” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Bread 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 bread is the right meal family. Then resolve the phrases that actually separate this set—“barley”, “multigrain, reduced calorie and/or high fiber, toasted”, “soy, toasted”, and “zucchini”—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 Bread 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 103 exact records behind Bread 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

Bread, whole grain white, toasted is higher in calcium per 100 g

Bread, whole grain white, toasted reports 752 mg versus 0 mg for Bread, sprouted wheat: a 752 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

The denominator changes the answer

Bread, barley is denser; Bread, French or Vienna is higher in its source amount

Bread, barley reports 274 kcal per 100 g and 77 kcal in USDA source amount (28 g). Bread, French or Vienna reports a lower 272 kcal per 100 g but a higher 174 kcal in USDA source amount (64 g).

Bread, gluten free, toasted and Bread, whole grain white are not interchangeable

The page keeps both records at the same 100 g denominator and makes Preparation wording (toasted versus No matching controlled term in the source name) 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.
