Cereal, plain puffs calories: 54 per 1 cup (15 g)
This exact USDA record reports 54 calories for 1 cup (15 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 54 calories for 1 cup at 15 grams. On a fixed-weight basis, the same record contains 357 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 1.4 g protein, 1.3 g fiber, and 1 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 49.7% of the record’s listed input weight. The record contains 4 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 54–107 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 2708478: “Cereal, plain puffs.” 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 2708478, each row multiplies the published per-100-gram values by its stated weight. “75% of the reference weight” through “1 prepackaged single serving” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 75% of the reference weightArithmetic scenario from the reference weight | 11.3 g | 40 kcal | 1.1 g | 1 g | 0 mg |
| 1 cupUSDA-listed household measure | 15 g | 54 kcal | 1.4 g | 1.3 g | 1 mg |
| 1 prepackaged single servingUSDA-listed household measure | 30 g | 107 kcal | 2.9 g | 2.6 g | 1 mg |
02 · Fixed-weight context
Where 100 grams sits inside Ready-to-eat cereal, lower sugar (=<21.2g/100g)
The comparison set contains 19 exact records in the Ready-to-eat cereal, lower sugar (=<21.2g/100g) USDA category. Here, “lower quarter” describes FDC 2708478’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 2708478’s 15 g reference weight, none of the compatible strength-side nutrients evaluated here reaches 5% Daily Value; 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
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
Saturated fat0 g
≈ 0% DV. This does not cross the FDA’s 20% ‘high’ guide.
Sodium1 mg
≈ 0% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Cereal, plain puffs,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708454 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 cup to 1 prepackaged single serving
USDA assigns those measures 15 g and 30 g. At this record’s fixed composition, scaled energy moves from 54 kcal to 107 kcal.
- 02
Record choice: compare with FDC 2708454
At an equal 100 g, this record has 521 mg less sodium than “Cereal, corn puffs.” 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 4 input rows; Flour, rice, white, unenriched supplies 49.7% 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 “plain puffs” fits. Inspect FDC 2708454 when “corn puffs” is the more literal description of the food and preparation.

Plain-English read
At the fixed 100-gram basis, this record lists 1.8 g more protein and 521 mg less sodium than “Cereal, corn puffs.”
Only this record lists Flour, rice, white, unenriched; Flour, wheat, all-purpose, unenriched, unbleached; Millet, puffed. Only the comparison record lists Cornmeal, degermed, unenriched, yellow; Sugars, granulated; Salt, table; Oil, canola. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
2 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: Fiber, total dietary, as ingredient.
Listed only in this record: Flour, rice, white, unenriched; Flour, wheat, all-purpose, unenriched, unbleached; Millet, puffed.
Listed only in the comparison: Cornmeal, degermed, unenriched, yellow; Sugars, granulated; Salt, table; Oil, canola; and 7 more.
Portion evidence
The listed portion sets differ
This record’s reference amount is 15 g; a familiar listed measure is 1 cup (15 g).
The comparison record’s reference amount is 25 g; a familiar listed measure is 1 cup (25 g).
Use the 100-gram row to compare FDC 2708478 with FDC 2708454 at equal mass; use their 15 g and 25 g source amounts only for portion matching.
Evidence boundary: FDC 2708478 versus FDC 2708454 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, plain puffs,” 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 2708478 comes from FoodData Central Survey Foods (FNDDS). Its 357 kcal per 100 g becomes 54 kcal at 15 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: 2708478
FNDDS food code: 57416000
The scaling for FDC 2708478 can be exact while the match to “Cereal, plain puffs” is wrong. That is why this profile keeps its 15 g weight, 4-row source formulation, and selection uncertainty beside the arithmetic.
