The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 4 calories for USDA reference amount at 360 grams. On a fixed-weight basis, the same record contains 1 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 0.2 g protein, 0 g fiber, and 14 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is beverages, water, tap, drinking, representing 99.7% of the record’s listed input weight. The record contains 2 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and 1 fl oz 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 0–4 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 2710498: “Tea, iced, instant, black, decaffeinated, unsweetened.” 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 2710498, each row multiplies the published per-100-gram values by its stated weight. “1 fl oz (with ice)” through “USDA reference amount” 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 | 0 kcal | 0 g | 0 g | 1 mg |
| 1 fl oz (no ice)USDA-listed household measure | 30 g | 0 kcal | 0 g | 0 g | 1 mg |
| USDA reference amountExact record reference weight | 360 g | 4 kcal | 0.2 g | 0 g | 14 mg |
02 · Fixed-weight context
Where 100 grams sits inside Tea
The comparison set contains 45 exact records in the Tea USDA category. Here, “middle half” describes FDC 2710498’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 2710498’s 360 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
Sodium14 mg
≈ 1% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Tea, iced, instant, black, decaffeinated, unsweetened,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2710493 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 fl oz (with ice) to 1 fl oz (no ice)
USDA assigns those measures 23 g and 30 g. At this record’s fixed composition, scaled energy moves from 0 kcal to 0 kcal.
- 02
Record choice: compare with FDC 2710493
At an equal 100 g, this record has 0 g more protein than “Tea, iced, instant, black, unsweetened.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Beverages, water, tap, drinking
The source formulation has 2 input rows; Beverages, water, tap, drinking supplies 99.7% 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 “iced; instant; black; decaffeinated” fits. Inspect FDC 2710493 when “iced; instant; black; unsweetened” is the more literal description of the food and preparation.

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, tea, instant, decaffeinated, unsweetened. Only the comparison record lists Beverages, tea, instant, lemon, unsweetened. 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: Beverages, water, tap, drinking.
Listed only in this record: Beverages, tea, instant, decaffeinated, unsweetened.
Listed only in the comparison: Beverages, tea, instant, lemon, unsweetened.
Portion evidence
The listed portion sets match
This record’s reference amount is 360 g; a familiar listed measure is 1 fl oz (30 g).
The comparison record’s reference amount is 360 g; a familiar listed measure is 1 fl oz (30 g).
Use the 100-gram row to compare FDC 2710498 with FDC 2710493 at equal mass; use their 360 g and 360 g source amounts only for portion matching.
Evidence boundary: FDC 2710498 versus FDC 2710493 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 “Tea, iced, instant, black, decaffeinated, unsweetened,” 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 2710498 comes from FoodData Central Survey Foods (FNDDS). Its 1 kcal per 100 g becomes 4 kcal at 360 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: 2710498
FNDDS food code: 92305180
The scaling for FDC 2710498 can be exact while the match to “Tea, iced, instant, black, decaffeinated, unsweetened” is wrong. That is why this profile keeps its 360 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
