The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 33 calories for USDA reference amount at 65 grams. On a fixed-weight basis, the same record contains 51 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 0.9 g protein, 1.2 g fiber, and 20 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is sauce, pasta, spaghetti/marinara, ready-to-serve, low sodium, 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 cup 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 33–133 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 2709747: “Spaghetti sauce, reduced sodium.” 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 2709747, each row multiplies the published per-100-gram values by its stated weight. “75% of the reference weight” through “1 cup” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 75% of the reference weightArithmetic scenario from the reference weight | 48.8 g | 25 kcal | 0.7 g | 0.9 g | 15 mg |
| USDA reference amountExact record reference weight | 65 g | 33 kcal | 0.9 g | 1.2 g | 20 mg |
| 1 cupUSDA-listed household measure | 260 g | 133 kcal | 3.7 g | 4.7 g | 78 mg |
02 · Fixed-weight context

The comparison set contains 10 exact records in the Pasta sauces, tomato-based USDA category. Here, “middle half” describes FDC 2709747’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 2709747’s 65 g reference weight, none of the compatible strength-side nutrients evaluated here reaches 5% Daily Value; 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.
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
Sodium20 mg
≈ 1% DV. This does not cross the FDA’s 20% ‘high’ guide.
Saturated fat0.1 g
≈ 1% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Spaghetti sauce, reduced sodium,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709745 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 65 g
A 25% weight move in either direction spans 48.8–81.3 g. When composition is held constant, those endpoints calculate to 25 kcal and 41 kcal.
- 02
Record choice: compare with FDC 2709745
At an equal 100 g, this record has 389 mg less sodium than “Spaghetti sauce.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Sauce, pasta, spaghetti/marinara, ready-to-serve, low sodium
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 “reduced sodium” fits. Inspect FDC 2709745 when the exact wording “Spaghetti sauce” is the more literal description of the food and preparation.

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 served, cooked-to-dry ratio, sauce or mix-ins, added fat.
For “Spaghetti sauce, reduced sodium,” resolve amount served first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
amount served
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
cooked-to-dry ratio
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.
- 03
sauce or mix-ins
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
- 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 2709747 comes from FoodData Central Survey Foods (FNDDS). Its 51 kcal per 100 g becomes 33 kcal at 65 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: 2709747
FNDDS food code: 74404050
The scaling for FDC 2709747 can be exact while the match to “Spaghetti sauce, reduced sodium” is wrong. That is why this profile keeps its 65 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
