Choose the bread type and slice size, then count the slices you ate. A regular packaged slice and a thick bakery slice can have very different weights.
A worked portion example
Illustrative calculation: 2 medium or regular slices weighs 56 g using the linked record's portion weight × 2. At 267 calories per 100 g, 56 × 267 ÷ 100 = about 150 calories and 5.3 g protein. This counts the bread for a sandwich; fillings and spreads are separate.
Check the exact food and household measure →The packaged white-bread example lists a thin slice as 24 g, regular as 28 g, and thick as 43 g. Two regular slices use 56 g in this example. Use your loaf's label or a scale for slices that do not match those sizes.
This guide separates toasted bread from untoasted bread, including bakery versions. Match the state you measured. If you know the original slices and use their package calories, keep that basis and add any butter or other spread rather than swapping to an unrelated slice weight after toasting.
A bread-only calculation does not include peanut butter, cheese, mayonnaise, or meat. Add the fillings for a sandwich you assemble yourself. If you use a complete sandwich entry instead, check its description before adding the bread again.
Editorial update: . Portion examples are calculations from the linked USDA records.
The 6 exact records in this guide report 66–120 calories in the records' own listed source servings and 238–299 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.
Across all 6 named USDA examples, a large or thick slice contains 102–150 calories. Their listed weights span 39–55 g, so each calorie value is calculated from that example's own gram weight and published calories per 100 g.
Match my meal
For White bread, begin by separating “Bread, white” from “Bread, white, toasted.” 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
This guide keeps 6 named USDA records in view: 6 direct matches. All sit within “Yeast 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 two description segments” placed these 6 records together under the exact grouping key “bread white.” That rule determines membership before any nutrition result is read.
For White bread, this page can compare 6 named records from FDC 2707598 through FDC 2707599. It cannot observe which preparation was eaten, recover unnamed additions, or supply the eaten grams.

Editor’s decision brief
Carry the denominator, exact identity, and strongest observed contrast into every number below.
Portion
The largest source amount is 1.8× the smallest. Read per-serving calorie differences with that mass gap in view.
Composition
The lower endpoint is “white, special formula, added fiber”; the higher is “white, made from home recipe or purchased at a bakery, toasted.” This isolates density, not ingredient causation.
Discriminator
Of protein, fiber, and sodium, the strongest normalized contrast is between “white, made from home recipe or purchased at a bakery” (1.7 g) and “white, special formula, added fiber, toasted” (10.1 g).
Observed source examples
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 white bread.

Full comparison
For White 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.

Portion analysis
The listed source amounts run from 25 to 44 grams—a 19-gram gap before composition enters the comparison. Their own source servings run from 66 calories for “white, special formula, added fiber, toasted” to 120 for “white, made from home recipe or purchased at a bakery.” At a fixed 100 grams, “white, special formula, added fiber” is 238 calories and “white, made from home recipe or purchased at a bakery, toasted” is 299—a fixed-weight separation of 61 calories. For White 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 published descriptions distinguish forms such as “white”, “white, made from home recipe or purchased at a bakery”, “white, special formula, added fiber”, “white, special formula, added fiber, toasted”, and “white, toasted”. The source formulations contain 12 distinct ingredient codes; examples that appear in only part of the set include bread, white, commercially prepared, beverages, water, tap, drinking, bread, white wheat, and bread, white, made from home recipe or purchased at a bakery. On this White 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
The family label “White bread” cannot resolve the differences between Bread, white and Bread, white, toasted. The four checks below identify the record wording, source weight, and formulation evidence that can.
The source amounts span 25–44 grams. Compare per 100 grams before reading a serving-calorie gap as a composition gap.
Representative record-level distinctions include “white”, “white, made from home recipe or purchased at a bakery”, “white, special formula, added fiber”, “white, special formula, added fiber, toasted”, and “white, toasted”. Those phrases are evidence for choosing a record, not decorative subtitle text.
12 source-input codes appear across the selected records. Their presence and listed weights describe USDA formulations, not finished plated proportions.
Even “Bread, white” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those White bread unknowns for correction instead of converting them into false precision.
Record matching
Read the source name as a sequence of decisions. First confirm that white bread is the right meal family. Then resolve the phrases that actually separate this set—“white”, “white, made from home recipe or purchased at a bakery, toasted”, “white, special formula, added fiber”, and “white, toasted”—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.
Decision support from the exact records on this page
These conclusions and reading paths are computed from 6 exact records behind White 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, white, special formula, added fiber, toasted reports 752 mg versus 38 mg for Bread, white, made from home recipe or purchased at a bakery: a 714 mg difference when both are normalized to 100 g.
Inspect the underlying evidenceThe denominator changes the answer
Bread, white, made from home recipe or purchased at a bakery, toasted reports 299 kcal per 100 g and 120 kcal in USDA source amount (40 g). Bread, white, made from home recipe or purchased at a bakery reports a lower 272 kcal per 100 g but a higher 120 kcal in USDA source amount (44 g).
Record identity is part of the estimate
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.
