The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 149 calories for 1 cup at 40 grams. On a fixed-weight basis, the same record contains 372 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2 g protein, 0.1 g fiber, and 142 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is flour, rice, white, unenriched, representing 58.8% of the record’s listed input weight. The record contains 8 source-input rows in all. 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 cup 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 112–149 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 2708458: “Cereal, rice crispy, flavored.” 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 2708458, each row multiplies the published per-100-gram values by its stated weight. “1 prepackaged single serving” through “125% of the reference weight” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 prepackaged single servingUSDA-listed household measure | 30 g | 112 kcal | 1.5 g | 0.1 g | 107 mg |
| 1 cupUSDA-listed household measure | 40 g | 149 kcal | 2 g | 0.1 g | 142 mg |
| 125% of the reference weightArithmetic scenario from the reference weight | 50 g | 186 kcal | 2.5 g | 0.2 g | 178 mg |
02 · Fixed-weight context
Where 100 grams sits inside Ready-to-eat cereal, higher sugar (>21.2g/100g)
The comparison set contains 20 exact records in the Ready-to-eat cereal, higher sugar (>21.2g/100g) USDA category. Here, “lower quarter” describes FDC 2708458’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 2708458’s 40 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Iron; 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.

04 · Highest-impact checks
The three levers most worth resolving first
For “Cereal, rice crispy, flavored,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708451 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 prepackaged single serving to 1 cup
USDA assigns those measures 30 g and 40 g. At this record’s fixed composition, scaled energy moves from 112 kcal to 149 kcal.
- 02
Record choice: compare with FDC 2708451
At an equal 100 g, this record has 1.1 g less dietary fiber than “Cereal, chocolate crispy.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Flour, rice, white, unenriched
The source formulation has 8 input rows; Flour, rice, white, unenriched supplies 58.8% 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 “rice crispy; flavored” fits. Inspect FDC 2708451 when “chocolate crispy” is the more literal description of the food and preparation.

Only the comparison record lists Oil, canola; Cocoa, dry powder, unsweetened. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
3 of the six displayed differences clear the documented materiality screen. It is a reading aid, not a health rating.
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: Flour, rice, white, unenriched; Sugars, granulated; Salt, table; Soy protein isolate; and 4 more.
Listed only in the comparison: Oil, canola; Cocoa, dry powder, unsweetened.
Portion evidence
The listed portion sets match
This record’s reference amount is 40 g; a familiar listed measure is 1 cup (40 g).
The comparison record’s reference amount is 40 g; a familiar listed measure is 1 cup (40 g).
Use the 100-gram row to compare FDC 2708458 with FDC 2708451 at equal mass; use their 40 g and 40 g source amounts only for portion matching.
Evidence boundary: FDC 2708458 versus FDC 2708451 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, recipe or brand, cooking fat, toppings and add-ins.
For “Cereal, rice crispy, flavored,” 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
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
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
toppings and add-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.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2708458 comes from FoodData Central Survey Foods (FNDDS). Its 372 kcal per 100 g becomes 149 kcal at 40 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 cup 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: 2708458
FNDDS food code: 57216000
The scaling for FDC 2708458 can be exact while the match to “Cereal, rice crispy, flavored” is wrong. That is why this profile keeps its 40 g weight, 8-row source formulation, and selection uncertainty beside the arithmetic.
