Bread, soy calories: 75 per 1 medium or regular slice (28 g)
This exact USDA record reports 75 calories for 1 medium or regular slice (28 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 75 calories for 1 medium or regular slice at 28 grams. On a fixed-weight basis, the same record contains 267 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 4.6 g protein, 1.2 g fiber, and 165 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is flour, bread, white, enriched, unbleached, representing 41.4% of the record’s listed input weight. The record contains 9 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 medium or regular slice at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 27–115 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.
Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2707790: “Bread, soy.” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.
01 · Portion arithmetic
Three weights, one fixed composition
For FDC 2707790, each row multiplies the published per-100-gram values by its stated weight. “1 slice, snack-size” through “1 large or thick slice” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 slice, snack-sizeUSDA-listed household measure | 10 g | 27 kcal | 1.6 g | 0.4 g | 59 mg |
| 1 medium or regular sliceUSDA-listed household measure | 28 g | 75 kcal | 4.6 g | 1.2 g | 165 mg |
| 1 large or thick sliceUSDA-listed household measure | 43 g | 115 kcal | 7.1 g | 1.9 g | 253 mg |

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2707790’s 28 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Iron; the larger tradeoff-side percentage is Sodium. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.

04 · Highest-impact checks
The three levers most worth resolving first
For “Bread, soy,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707791 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 slice, snack-size to 1 large or thick slice
USDA assigns those measures 10 g and 43 g. At this record’s fixed composition, scaled energy moves from 27 kcal to 115 kcal.
- 02
Record choice: compare with FDC 2707791
At an equal 100 g, this record has 26 kcal less calories than “Bread, soy, toasted.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Flour, bread, white, enriched, unbleached
The source formulation has 9 input rows; Flour, bread, white, enriched, unbleached supplies 41.4% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “soy” fits. Inspect FDC 2707791 when “soy; toasted” is the more literal description of the food and preparation.

Exact-record context
What makes this USDA record distinct?
For FDC 2707790, the close-record rule searches the USDA “Yeast breads” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

Plain-English read
At the fixed 100-gram basis, this record lists 26 less calories than “Bread, soy, toasted.”
Only this record lists Beverages, water, tap, drinking; Milk, NFS; Salt, table; Sugars, granulated. Only the comparison record lists Bread, soy. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
1 of the six displayed differences clears the documented materiality screen. It is a reading aid, not a health rating.
Formulation evidence
The listed formulations differ
The formulation rows differ, but the source data do not isolate which component caused any nutrient difference. Input weights describe the standardized formulation—not final plated proportions.
Listed only in this record: Beverages, water, tap, drinking; Milk, NFS; Salt, table; Sugars, granulated; and 5 more.
Listed only in the comparison: Bread, soy.
Portion evidence
The listed portion sets differ
This record’s reference amount is 28 g; a familiar listed measure is 1 medium or regular slice (28 g).
The comparison record’s reference amount is 25 g; a familiar listed measure is 1 medium or regular slice (25 g).
Use the 100-gram row to compare FDC 2707790 with FDC 2707791 at equal mass; use their 28 g and 25 g source amounts only for portion matching.
Evidence boundary: FDC 2707790 versus FDC 2707791 is a comparison of standardized source records—not a measurement of your meal, an overall food-quality rank, or proof that one input caused a difference.

Uncertainty, made actionable
What can change this estimate?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with item size, recipe or brand, moisture and density, spreads or toppings.
For “Bread, soy,” resolve item size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
item size
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
- 02
recipe or brand
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
moisture and density
Match the food state before matching the number. Cooking, draining, or added liquid can change grams and concentration even when the food name barely changes.
- 04
spreads or toppings
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2707790 comes from FoodData Central Survey Foods (FNDDS). Its 267 kcal per 100 g becomes 75 kcal at 28 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.
About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 medium or regular slice has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2707790
FNDDS food code: 51804010
The scaling for FDC 2707790 can be exact while the match to “Bread, soy” is wrong. That is why this profile keeps its 28 g weight, 9-row source formulation, and selection uncertainty beside the arithmetic.
