The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 75 calories for 1 slice at 21 grams. On a fixed-weight basis, the same record contains 356 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 5.2 g protein, 0 g fiber, and 172 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is cheese, gouda, representing 100% of the record’s listed input weight. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 slice at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 32–470 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 2705732: “Cheese, Port du Salut.” 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 2705732, each row multiplies the published per-100-gram values by its stated weight. “1 cracker-size slice” through “1 cup, diced” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 cracker-size sliceUSDA-listed household measure | 9 g | 32 kcal | 2.2 g | 0 g | 74 mg |
| 1 sliceUSDA-listed household measure | 21 g | 75 kcal | 5.2 g | 0 g | 172 mg |
| 1 cup, dicedUSDA-listed household measure | 132 g | 470 kcal | 32.9 g | 0 g | 1,081 mg |
02 · Fixed-weight context
Where 100 grams sits inside Cheese
The comparison set contains 41 exact records in the Cheese USDA category. Here, “middle half” describes FDC 2705732’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 2705732’s 21 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
Calcium147 mg
≈ 11% DV. This does not cross the FDA’s 20% ‘high’ guide.
Tradeoff-side signals
Saturated fat3.7 g
≈ 18% DV. This does not cross the FDA’s 20% ‘high’ guide.
Sodium172 mg
≈ 7% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Cheese, Port du Salut,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2705717 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 cracker-size slice to 1 cup, diced
USDA assigns those measures 9 g and 132 g. At this record’s fixed composition, scaled energy moves from 32 kcal to 470 kcal.
- 02
Record choice: compare with FDC 2705717
At an equal 100 g, this record has calories than “Cheese, Gouda or Edam.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Cheese, gouda
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 “Port du Salut” fits. Inspect FDC 2705717 when “Gouda or Edam” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2705732 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Cheese, Port du Salut” inspectable beside similarly named records.
How to read this
A single-source formulation
Cheese, gouda is the only listed source input for this record. That does not mean every real-world version is identical; brands, preparation, water content, and portion weight can still differ.

Exact-record context
What makes this USDA record distinct?
For FDC 2705732, the close-record rule searches the USDA “Cheese” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

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.
Formulation evidence
The listed formulations match
The USDA input rows shown on these profiles are identical. The nutrient or portion distinction therefore should not be attributed to a different named input.
Shared listed inputs: Cheese, gouda.
Portion evidence
The listed portion sets differ
This record’s reference amount is 21 g; a familiar listed measure is 1 slice (21 g).
The comparison record’s reference amount is 21 g; a familiar listed measure is 1 slice (21 g).
Use the 100-gram row to compare FDC 2705732 with FDC 2705717 at equal mass; use their 21 g and 21 g source amounts only for portion matching.
Evidence boundary: FDC 2705732 versus FDC 2705717 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 portion size, fat level, brand or formulation, added flavors or sweeteners.
For “Cheese, Port du Salut,” resolve portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
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.
- 02
fat level
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
- 03
brand or formulation
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 04
added flavors or sweeteners
Use a label or known recipe when available, because sweetness does not reveal dose. Keep syrups, sugars, and concentrated add-ins separate when the base record does not name them.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2705732 comes from FoodData Central Survey Foods (FNDDS). Its 356 kcal per 100 g becomes 75 kcal at 21 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.” The separately listed 1 slice has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2705732
FNDDS food code: 14108200
The scaling for FDC 2705732 can be exact while the match to “Cheese, Port du Salut” is wrong. That is why this profile keeps its 21 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
