The editorial read
Portion: the cited record reports about 186 calories for USDA reference amount at 35 grams. On a fixed-weight basis, the same record contains 530 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 3.1 g protein, 3.5 g fiber, and 267 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is snacks, popcorn, air-popped, representing 68.6% of the record’s listed input weight. The record contains 3 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and 1 small bag 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 1–451 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
This analysis belongs to USDA FDC 2708235: “Popcorn, ready-to-eat, butter 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
For FDC 2708235, each row multiplies the published per-100-gram values by its stated weight. “1 kernel” through “1 large single serving bag” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 kernelUSDA-listed household measure | 0.2 g | 1 kcal | 0 g | 0 g | 2 mg |
| 1 small single serving bagUSDA-listed household measure | 28 g | 148 kcal | 2.5 g | 2.8 g | 214 mg |
| 1 large single serving bagUSDA-listed household measure | 85 g | 451 kcal | 7.5 g | 8.5 g | 649 mg |
02 · Fixed-weight context
The comparison set contains 23 exact records in the Popcorn USDA category. Here, “upper quarter” describes FDC 2708235’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
At FDC 2708235’s 35 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Dietary fiber; 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.
Dietary fiber3.5 g
≈ 13% DV. This does not cross the FDA’s 20% ‘high’ guide.
Magnesium35 mg
≈ 8% DV. This does not cross the FDA’s 20% ‘high’ guide.
Sodium267 mg

04 · Highest-impact checks
For “Popcorn, ready-to-eat, butter flavored,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708232 alternative, and its source-formulation identity.
USDA assigns those measures 0.2 g and 85 g. At this record’s fixed composition, scaled energy moves from 1 kcal to 451 kcal.
At an equal 100 g, this record has 9.2 g more total fat than “Popcorn, ready-to-eat, plain.” That is a record-level contrast; it does not identify which ingredient caused the difference.
The source formulation has 3 input rows; Snacks, popcorn, air-popped supplies 68.6% of listed input weight. Those are standardized formulation inputs, not final plated percentages.

5 of the six displayed differences clear the documented materiality screen. It is a reading aid, not a health rating.
Formulation evidence
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: Snacks, popcorn, air-popped; Oil, corn; Salt, table.
The ingredient codes overlap, while at least one listed amount, weight, sequence, or formulation detail differs.
Portion evidence
This record’s reference amount is 35 g; a familiar listed measure is 1 small bag (28 g).
The comparison record’s reference amount is 28 g; a familiar listed measure is 1 small bag (28 g).
Use the 100-gram row to compare FDC 2708235 with FDC 2708232 at equal mass; use their 35 g and 28 g source amounts only for portion matching.
Evidence boundary: FDC 2708235 versus FDC 2708232 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.

FDC 2708235 appears in 2 pair pages that passed semantic, material-difference, source-evidence, and diversity gates. Each preserves a 100-gram denominator and both primary records.
From record to familiar meal
These 2 guides place “Popcorn, ready-to-eat, butter flavored” beside explicitly linked source records; use them to compare preparations without turning FDC 2708235 into a universal recipe.
Uncertainty, made actionable
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with piece or portion size, recipe or brand, fillings or frosting, added fats and sugars.
For “Popcorn, ready-to-eat, butter flavored,” resolve piece or portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
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
FDC 2708235 comes from FoodData Central Survey Foods (FNDDS). Its 530 kcal per 100 g becomes 186 kcal at 35 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: 2708235
FNDDS food code: 54403085
The scaling for FDC 2708235 can be exact while the match to “Popcorn, ready-to-eat, butter flavored” is wrong. That is why this profile keeps its 35 g weight, 3-row source formulation, and selection uncertainty beside the arithmetic.
