The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 409 calories for 1 piece, NFS at 158 grams. On a fixed-weight basis, the same record contains 259 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 22.8 g protein, 6.8 g fiber, and 749 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is school lunch, pizza, pepperoni topping, thick crust, whole grain, frozen, cooked, 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 piece, NFS 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 16–461 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 2708645: “Pizza with pepperoni, from school lunch, thick crust.” 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 2708645, each row multiplies the published per-100-gram values by its stated weight. “1 surface inch” through “1 personal size pizza (5-7" diameter)” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 surface inchUSDA-listed household measure | 6.3 g | 16 kcal | 0.9 g | 0.3 g | 30 mg |
| 1 piece, NFSUSDA-listed household measure | 158 g | 409 kcal | 22.8 g | 6.8 g | 749 mg |
| 1 personal size pizza (5-7" diameter)USDA-listed household measure | 178 g | 461 kcal | 25.6 g | 7.7 g | 844 mg |
02 · Fixed-weight context
Where 100 grams sits inside Pizza
The comparison set contains 86 exact records in the Pizza USDA category. Here, “middle half” describes FDC 2708645’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 2708645’s 158 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Dietary fiber; 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.

04 · Highest-impact checks
The three levers most worth resolving first
For “Pizza with pepperoni, from school lunch, thick crust,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708644 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 surface inch to 1 personal size pizza (5-7" diameter)
USDA assigns those measures 6.3 g and 178 g. At this record’s fixed composition, scaled energy moves from 16 kcal to 461 kcal.
- 02
Record choice: compare with FDC 2708644
At an equal 100 g, this record has 0.6 g more total fat than “Pizza, with pepperoni, from school lunch, medium crust.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: School Lunch, pizza, pepperoni topping, thick crust, whole grain, frozen, cooked
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 “from school lunch; thick crust” fits. Inspect FDC 2708644 when “with pepperoni; from school lunch; medium crust” is the more literal description of the food and preparation.

Exact-record context
What makes this USDA record distinct?
For FDC 2708645, the close-record rule searches the USDA “Pizza” 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.
Only the comparison record lists School Lunch, pizza, pepperoni topping, thin crust, whole grain, frozen, cooked. 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: School Lunch, pizza, pepperoni topping, thick crust, whole grain, frozen, cooked.
Listed only in the comparison: School Lunch, pizza, pepperoni topping, thin crust, whole grain, frozen, cooked.
Portion evidence
The listed portion sets differ
This record’s reference amount is 158 g; a familiar listed measure is 1 piece, NFS (158 g).
The comparison record’s reference amount is 147 g; a familiar listed measure is 1 piece, NFS (147 g).
Use the 100-gram row to compare FDC 2708645 with FDC 2708644 at equal mass; use their 158 g and 147 g source amounts only for portion matching.
Evidence boundary: FDC 2708645 versus FDC 2708644 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 amount served, recipe and ingredient ratios, added cooking fat, sauces and toppings.
For “Pizza with pepperoni, from school lunch, thick crust,” 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
recipe and ingredient ratios
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
added cooking 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.
- 04
sauces and toppings
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2708645 comes from FoodData Central Survey Foods (FNDDS). Its 259 kcal per 100 g becomes 409 kcal at 158 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 piece, NFS 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: 2708645
FNDDS food code: 58106580
The scaling for FDC 2708645 can be exact while the match to “Pizza with pepperoni, from school lunch, thick crust” is wrong. That is why this profile keeps its 158 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
