The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 59 calories for USDA reference amount at 39 grams. On a fixed-weight basis, the same record contains 150 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 3.3 g protein, 0.3 g fiber, and 35 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is tofu, soft, prepared with calcium sulfate and magnesium chloride (nigari), representing 80% of the record’s listed input weight. The record contains 5 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and 1 slice answer different portion questions. Their values are scaled independently from the same per-100-gram source record.
The household measures attached to this record span roughly 26–59 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 2707449: “Soybean curd, breaded, fried.” 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 2707449, each row multiplies the published per-100-gram values by its stated weight. “1 cubic inch” through “USDA reference amount” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 cubic inchUSDA-listed household measure | 17 g | 26 kcal | 1.4 g | 0.1 g | 15 mg |
| 1 slice (2-3/4" x 1" x 1/2")USDA-listed household measure | 29 g | 44 kcal | 2.4 g | 0.2 g | 26 mg |
| USDA reference amountExact record reference weight | 39 g | 59 kcal | 3.3 g | 0.3 g | 35 mg |
02 · Fixed-weight context
Where 100 grams sits inside Soy and meat-alternative products
The comparison set contains 18 exact records in the Soy and meat-alternative products USDA category. Here, “lower quarter” describes FDC 2707449’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2707449’s 39 g reference weight, none of the compatible strength-side nutrients evaluated here reaches 5% Daily Value; the larger tradeoff-side percentage is Saturated fat. 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.
Strength-side signals
No compatible strength-side nutrient evaluated here reaches 5% DV at this reference weight, so this page does not manufacture a “strength” from a negligible percentage.
Tradeoff-side signals
Saturated fat0.8 g
≈ 4% DV. This does not cross the FDA’s 20% ‘high’ guide.
Sodium35 mg
≈ 2% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Soybean curd, breaded, fried,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707435 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 cubic inch to 1 slice (2-3/4" x 1" x 1/2")
USDA assigns those measures 17 g and 29 g. At this record’s fixed composition, scaled energy moves from 26 kcal to 44 kcal.
- 02
Record choice: compare with FDC 2707435
At an equal 100 g, this record has 83 mg more sodium than “Soybean curd.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Tofu, soft, prepared with calcium sulfate and magnesium chloride (nigari)
The source formulation has 5 input rows; Tofu, soft, prepared with calcium sulfate and magnesium chloride (nigari) supplies 80% 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 “breaded; fried” fits. Inspect FDC 2707435 when the exact wording “Soybean curd” is the more literal description of the food and preparation.

Plain-English read
At the fixed 100-gram basis, this record lists 89 more calories, 1.2 g more protein, and 7.5 g more carbohydrate than “Soybean curd.”
Only this record lists Eggs, Grade A, Large, egg whole; Bread, crumbs, dry, grated, plain; Beverages, water, tap, municipal; Shortening, vegetable, household, composite. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
6 of the six displayed differences clear 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.
Shared listed inputs: Tofu, soft, prepared with calcium sulfate and magnesium chloride (nigari).
Listed only in this record: Eggs, Grade A, Large, egg whole; Bread, crumbs, dry, grated, plain; Beverages, water, tap, municipal; Shortening, vegetable, household, composite.
Portion evidence
The listed portion sets differ
This record’s reference amount is 39 g; a familiar listed measure is 1 slice (29 g).
The comparison record’s reference amount is 62 g; a familiar listed measure is 1 piece (120 g).
Use the 100-gram row to compare FDC 2707449 with FDC 2707435 at equal mass; use their 39 g and 62 g source amounts only for portion matching.
Evidence boundary: FDC 2707449 versus FDC 2707435 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 amount of absorbed frying fat, portion size, preparation, added fat.
For “Soybean curd, breaded, fried,” resolve amount of absorbed frying fat first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
amount of absorbed frying fat
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
- 02
portion 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.
- 03
preparation
Match the method named by the source—such as baked, fried, boiled, or grilled—before scaling. Preparation can change both water content and the ingredients retained in the finished food.
- 04
added fat
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2707449 comes from FoodData Central Survey Foods (FNDDS). Its 150 kcal per 100 g becomes 59 kcal at 39 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.” We display it as a USDA reference amount because it is a database comparison point—not a suggested portion or a claim about what most people should eat.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2707449
FNDDS food code: 41421020
The scaling for FDC 2707449 can be exact while the match to “Soybean curd, breaded, fried” is wrong. That is why this profile keeps its 39 g weight, 5-row source formulation, and selection uncertainty beside the arithmetic.
