The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 17 calories for USDA reference amount at 30 grams. On a fixed-weight basis, the same record contains 56 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 0.3 g protein, 0.2 g fiber, and 327 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is salad dressing, italian dressing, fat-free, representing 85% of the record’s listed input weight. The record contains 2 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and 1 tablespoon 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 8–134 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 2710231: “Creamy Italian dressing, fat free.” 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 2710231, each row multiplies the published per-100-gram values by its stated weight. “1 tablespoon” through “1 cup” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 tablespoonUSDA-listed household measure | 15 g | 8 kcal | 0.2 g | 0.1 g | 164 mg |
| 1 packetUSDA-listed household measure | 44 g | 25 kcal | 0.5 g | 0.2 g | 480 mg |
| 1 cupUSDA-listed household measure | 240 g | 134 kcal | 2.5 g | 1.2 g | 2,616 mg |
02 · Fixed-weight context
Where 100 grams sits inside Salad dressings and vegetable oils
The comparison set contains 47 exact records in the Salad dressings and vegetable oils USDA category. Here, “lower quarter” describes FDC 2710231’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 2710231’s 30 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
Sodium327 mg
≈ 14% DV. This does not cross the FDA’s 20% ‘high’ guide.
Saturated fat0.1 g
≈ 0% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Creamy Italian dressing, fat free,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2710234 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 tablespoon to 1 cup
USDA assigns those measures 15 g and 240 g. At this record’s fixed composition, scaled energy moves from 8 kcal to 134 kcal.
- 02
Record choice: compare with FDC 2710234
At an equal 100 g, this record has 0.3 g more total fat than “Italian dressing, fat free.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Salad dressing, italian dressing, fat-free
The source formulation has 2 input rows; Salad dressing, italian dressing, fat-free supplies 85% 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 “fat free” fits. Inspect FDC 2710234 when “fat free” is the more literal description of the food and preparation.

Plain-English read
The six displayed nutrient values are close under a conservative materiality screen. Small differences remain exact source values, not evidence that one food is preferable.
Only this record lists Creamy dressing, made with sour cream and/or buttermilk and oil, reduced calorie, fat-free. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
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: Salad dressing, italian dressing, fat-free.
Listed only in this record: Creamy dressing, made with sour cream and/or buttermilk and oil, reduced calorie, fat-free.
Portion evidence
The listed portion sets differ
This record’s reference amount is 30 g; a familiar listed measure is 1 tablespoon (15 g).
The comparison record’s reference amount is 28 g; a familiar listed measure is 1 Nutri System packet (28 g).

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 used, recipe or brand, concentration, oil, sugar, and salt formulation.
For “Creamy Italian dressing, fat free,” resolve amount used first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
amount used
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
concentration
Estimate what was actually consumed, including liquid left behind. The same bowl volume can contain a different mass and solid-to-liquid balance.
- 04
oil, sugar, and salt formulation
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 2710231 comes from FoodData Central Survey Foods (FNDDS). Its 56 kcal per 100 g becomes 17 kcal at 30 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: 2710231
FNDDS food code: 83300250
The scaling for FDC 2710231 can be exact while the match to “Creamy Italian dressing, fat free” is wrong. That is why this profile keeps its 30 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
