The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 2 calories for USDA reference amount at 8 grams. On a fixed-weight basis, the same record contains 22 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 0 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is lemon juice, raw, representing 100% of the record’s listed input weight. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and Juice of 1 wedge or slice 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 0–10 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 2709181: “Lemon juice, 100%, freshly squeezed.” 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 2709181, each row multiplies the published per-100-gram values by its stated weight. “1 drop” through “Juice of 1 lemon (2-1/8" dia)” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 dropUSDA-listed household measure | 0.1 g | 0 kcal | 0 g | 0 g | 0 mg |
| Juice of 1 wedge or sliceUSDA-listed household measure | 6 g | 1 kcal | 0 g | 0 g | 0 mg |
| Juice of 1 lemon (2-1/8" dia)USDA-listed household measure | 47 g | 10 kcal | 0.2 g | 0.1 g | 0 mg |
02 · Fixed-weight context
Where 100 grams sits inside Mustard and other condiments
The comparison set contains 11 exact records in the Mustard and other condiments USDA category. Here, “lower quarter” describes FDC 2709181’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 2709181’s 8 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.
Sodium0 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 “Lemon juice, 100%, freshly squeezed,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709184 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 drop to Juice of 1 lemon (2-1/8" dia)
USDA assigns those measures 0.1 g and 47 g. At this record’s fixed composition, scaled energy moves from 0 kcal to 10 kcal.
- 02
Record choice: compare with FDC 2709184
At an equal 100 g, this record has 0.2 g more total fat than “Lime juice, 100%, freshly squeezed.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Lemon juice, raw
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 “100%; freshly squeezed” fits. Inspect FDC 2709184 when “100%; freshly squeezed” is the more literal description of the food and preparation.

Which USDA record fits your meal?
Treat the long description as data. The phrases doing the most work here are “100%” and “freshly squeezed”. Match those details first; then compare the database weight with the amount you mean.
On smaller screens, focus a nutrition table and scroll horizontally to read every column.
| Exact record | Source serving | Calories / 100 g | Protein / 100 g | Fat / 100 g | Fiber / 100 g | Sodium / 100 g |
|---|---|---|---|---|---|---|

| Lime juice, 100%, canned or bottled | 8 g2 kcal | 21 kcal | 0.3 g | 0.2 g | 0.4 g | 16 mg |
How to compare FDC 2709181: its source amount is 8 g; every 100-gram column removes portion size from the record-to-record comparison. Neither denominator determines your plate’s weight or recipe.

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 Lemon juice, raw. Only the comparison record lists Lime juice, raw. 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: Lemon juice, raw.
Listed only in the comparison: Lime juice, raw.
Portion evidence
The listed portion sets differ
This record’s reference amount is 8 g; a familiar listed measure is Juice of 1 wedge or slice (6 g).
The comparison record’s reference amount is 8 g; a familiar listed measure is Juice of 1 wedge or slice (5 g).
Use the 100-gram row to compare FDC 2709181 with FDC 2709184 at equal mass; use their 8 g and 8 g source amounts only for portion matching.
Evidence boundary: FDC 2709181 versus FDC 2709184 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 amount used, recipe or brand, concentration, oil, sugar, and salt formulation.
For “Lemon juice, 100%, freshly squeezed,” resolve amount used first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
amount used
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
concentration
Estimate what was actually consumed, including liquid left behind. The same bowl volume can contain a different mass and solid-to-liquid balance.
- 04
oil, sugar, and salt formulation
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
The arithmetic is simple; the provenance is the point
FDC 2709181 comes from FoodData Central Survey Foods (FNDDS). Its 22 kcal per 100 g becomes 2 kcal at 8 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: 2709181
FNDDS food code: 61204010
The scaling for FDC 2709181 can be exact while the match to “Lemon juice, 100%, freshly squeezed” is wrong. That is why this profile keeps its 8 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
