The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 153 calories for 1 small drink at 372 grams. On a fixed-weight basis, the same record contains 41 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 0 g protein, 0 g fiber, and 48 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is beverages, carbonated, root beer, 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 small drink 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 9–419 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 2710557: “Soft drink, root beer.” 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 2710557, each row multiplies the published per-100-gram values by its stated weight. “1 fl oz (with ice)” through “1 extra large drink” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 fl oz (with ice)USDA-listed household measure | 23 g | 9 kcal | 0 g | 0 g | 3 mg |
| 1 can (12 fl oz)USDA-listed household measure | 372 g | 153 kcal | 0 g | 0 g | 48 mg |
| 1 extra large drinkUSDA-listed household measure | 1,023 g | 419 kcal | 0 g | 0 g | 133 mg |
02 · Fixed-weight context
Where 100 grams sits inside Soft drinks
The comparison set contains 12 exact records in the Soft drinks USDA category. Here, “middle half” describes FDC 2710557’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 2710557’s 372 g reference weight, none of the compatible strength-side nutrients evaluated here reaches 5% Daily Value; 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.
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
Sodium48 mg
≈ 2% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Soft drink, root beer,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2710541 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 fl oz (with ice) to 1 extra large drink
USDA assigns those measures 23 g and 1,023 g. At this record’s fixed composition, scaled energy moves from 9 kcal to 419 kcal.
- 02
Record choice: compare with FDC 2710541
At an equal 100 g, this record has 0.3 g less total fat than “Soft drink, cola.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Beverages, carbonated, root beer
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 “root beer” fits. Inspect FDC 2710541 when “cola” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2710557 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Soft drink, root beer” inspectable beside similarly named records.
How to read this
A single-source formulation
Beverages, carbonated, root beer 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 2710557, the close-record rule searches the USDA “Soft drinks” 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 this record lists Beverages, carbonated, root beer. Only the comparison record lists Beverages, carbonated, cola, regular. 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.
Listed only in this record: Beverages, carbonated, root beer.
Listed only in the comparison: Beverages, carbonated, cola, regular.
Portion evidence
The listed portion sets match
This record’s reference amount is 372 g; a familiar listed measure is 1 small drink (372 g).
The comparison record’s reference amount is 372 g; a familiar listed measure is 1 small drink (372 g).
Use the 100-gram row to compare FDC 2710557 with FDC 2710541 at equal mass; use their 372 g and 372 g source amounts only for portion matching.
Evidence boundary: FDC 2710557 versus FDC 2710541 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 drink size, recipe or formulation, milk or cream, sweeteners and add-ins.
For “Soft drink, root beer,” resolve drink size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
drink size
Resolve drink size only when the meal or its source gives you evidence. If it is unknown, leave the uncertainty visible instead of choosing the most convenient variant.
- 02
recipe 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.
- 03
milk or cream
Identify the liquid base and fat level when you can. Dairy, plant-based beverages, cream, and water are different record choices—not interchangeable volume adjustments.
- 04
sweeteners and add-ins
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 2710557 comes from FoodData Central Survey Foods (FNDDS). Its 41 kcal per 100 g becomes 153 kcal at 372 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 small drink 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: 2710557
FNDDS food code: 92410710
The scaling for FDC 2710557 can be exact while the match to “Soft drink, root beer” is wrong. That is why this profile keeps its 372 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
