The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 30 calories for USDA reference amount at 78 grams. On a fixed-weight basis, the same record contains 38 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 0.6 g protein, 0.6 g fiber, and 23 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is melons, cantaloupe, 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 1 medium wedge/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 6–310 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 2709226: “Cantaloupe, raw.” 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 2709226, each row multiplies the published per-100-gram values by its stated weight. “1 cube” through “1 large melon” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 cubeUSDA-listed household measure | 15 g | 6 kcal | 0.1 g | 0.1 g | 5 mg |
| 1 medium wedge/sliceUSDA-listed household measure | 70 g | 27 kcal | 0.6 g | 0.6 g | 21 mg |
| 1 large melonUSDA-listed household measure | 815 g | 310 kcal | 6.7 g | 6.5 g | 245 mg |
02 · Fixed-weight context

04 · Highest-impact checks
The three levers most worth resolving first
For “Cantaloupe, raw,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709270 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 cube to 1 large melon
USDA assigns those measures 15 g and 815 g. At this record’s fixed composition, scaled energy moves from 6 kcal to 310 kcal.
- 02
Record choice: compare with FDC 2709270
At an equal 100 g, this record has 29 mg more sodium than “Watermelon, raw.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Melons, cantaloupe, 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 “raw” fits. Inspect FDC 2709270 when “raw” 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 Melons, cantaloupe, raw. Only the comparison record lists Watermelon, 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: Melons, cantaloupe, raw.
Listed only in the comparison: Watermelon, raw.
Portion evidence
The listed portion sets differ
This record’s reference amount is 78 g; a familiar listed measure is 1 medium wedge/slice (70 g).
The comparison record’s reference amount is 78 g; a familiar listed measure is 1 cup (155 g).
Use the 100-gram row to compare FDC 2709226 with FDC 2709270 at equal mass; use their 78 g and 78 g source amounts only for portion matching.
Evidence boundary: FDC 2709226 versus FDC 2709270 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 piece or portion size, variety and ripeness, fresh versus cooked form, added sweeteners.
For “Cantaloupe, raw,” 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.
- 01
piece or 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
variety and ripeness
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
fresh versus cooked form
Match the food state before matching the number. Cooking, draining, or added liquid can change grams and concentration even when the food name barely changes.
- 04
added sweeteners
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 2709226 comes from FoodData Central Survey Foods (FNDDS). Its 38 kcal per 100 g becomes 30 kcal at 78 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: 2709226
FNDDS food code: 63109010
The scaling for FDC 2709226 can be exact while the match to “Cantaloupe, raw” is wrong. That is why this profile keeps its 78 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
