The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 105 calories for USDA reference amount at 39 grams. On a fixed-weight basis, the same record contains 270 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 7.3 g protein, 1.5 g fiber, and 6 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is tofu, fried, representing 100% of the record’s listed input weight. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and 1 oz 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 77–105 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 2707448: “Soybean curd, deep 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 2707448, each row multiplies the published per-100-gram values by its stated weight. “1 oz” 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 ozUSDA-listed household measure | 28.4 g | 77 kcal | 5.3 g | 1.1 g | 5 mg |
| 75% of the reference weightArithmetic scenario from the reference weight | 29.3 g | 79 kcal | 5.5 g | 1.1 g | 5 mg |
| USDA reference amountExact record reference weight | 39 g | 105 kcal | 7.3 g | 1.5 g | 6 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, “middle half” describes FDC 2707448’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 2707448’s 39 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Calcium; 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

04 · Highest-impact checks
The three levers most worth resolving first
For “Soybean curd, deep fried,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707449 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 39 g
A 25% weight move in either direction spans 29.3–48.8 g. When composition is held constant, those endpoints calculate to 79 kcal and 132 kcal.
- 02
Record choice: compare with FDC 2707449
At an equal 100 g, this record has 75 mg less sodium than “Soybean curd, breaded, fried.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Tofu, fried
USDA derives this record from one listed source-input row at 100 g. Real preparations can still differ in water, cooking state, brand, and served weight.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “deep fried” fits. Inspect FDC 2707449 when “breaded; fried” is the more literal description of the food and preparation.

Plain-English read
At the fixed 100-gram basis, this record lists 120 more calories, 10.4 g more protein, and 10.6 g more total fat than “Soybean curd, breaded, fried.”
Only this record lists Tofu, fried. Only the comparison record lists Tofu, soft, prepared with calcium sulfate and magnesium chloride (nigari); Eggs, Grade A, Large, egg whole; Bread, crumbs, dry, grated, plain; Beverages, water, tap, municipal. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
5 of the six displayed differences clear the documented materiality screen. It is a reading aid, not a health rating.

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, deep 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 2707448 comes from FoodData Central Survey Foods (FNDDS). Its 270 kcal per 100 g becomes 105 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: 2707448
FNDDS food code: 41421010
The scaling for FDC 2707448 can be exact while the match to “Soybean curd, deep fried” is wrong. That is why this profile keeps its 39 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
