The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 38 calories for USDA reference amount at 33 grams. On a fixed-weight basis, the same record contains 115 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 0.5 g protein, 0.6 g fiber, and 269 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, blue or roquefort cheese dressing, fat-free, 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 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 19–305 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 2710229: “Blue or roquefort cheese 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 2710229, 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 | 16.6 g | 19 kcal | 0.3 g | 0.3 g | 135 mg |
| 1 packetUSDA-listed household measure | 44 g | 51 kcal | 0.7 g | 0.8 g | 358 mg |
| 1 cupUSDA-listed household measure | 265 g | 305 kcal | 4 g | 4.8 g | 2,157 mg |

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2710229’s 33 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
Sodium269 mg
≈ 12% 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 “Blue or roquefort cheese dressing, fat free,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2710216 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 tablespoon to 1 cup
USDA assigns those measures 16.6 g and 265 g. At this record’s fixed composition, scaled energy moves from 19 kcal to 305 kcal.
- 02
Record choice: compare with FDC 2710216
At an equal 100 g, this record has 25.1 g less total fat than “Blue or roquefort cheese dressing, light.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Salad dressing, blue or roquefort cheese dressing, fat-free
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 “fat free” fits. Inspect FDC 2710216 when “light” 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 used, recipe or brand, concentration, oil, sugar, and salt formulation.
For “Blue or roquefort cheese 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 2710229 comes from FoodData Central Survey Foods (FNDDS). Its 115 kcal per 100 g becomes 38 kcal at 33 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: 2710229
FNDDS food code: 83300100
The scaling for FDC 2710229 can be exact while the match to “Blue or roquefort cheese dressing, fat free” is wrong. That is why this profile keeps its 33 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
