Exact nutrition reference, complete food catalog and source methodology

For calories, macros, portions, and household measures, use Watermelon, raw, the exact cited complete FNDDS profile. This page answers the separate formulation question: where USDA lists input code 9326 across Feast’s reference corpus.

What the code means

One exact source label across 4 complete records.

Every occurrence collected here uses ingredient code 9326 and the source description “Watermelon, raw.” The code is preserved exactly as it appears in the FNDDS input-food rows. It is not a FoodData Central FDC ID, so this page does not invent a standalone ingredient-record URL.

The strongest concentrations of linked records are currently Other fruits and fruit salads (2), Melons (1), Soups, broth-based (1). These are category counts within Feast’s selected 3,850-record corpus. They do not estimate how often the ingredient is eaten, how common it is in recipes generally, or its prevalence across every FNDDS release.

Collection-level interpretation

Grounded ways to understand this source label

These summaries describe the linked FNDDS records in this exact corpus. They do not estimate consumer frequency, market share, or the composition of a meal. This is a very small set of 4 records: each observation can move the percentages, buckets, and interpolated quartiles substantially, so read the complete catalog rather than treating the summaries as stable population estimates.

Typical listed-weight range

10.7%–40%

The middle half of linked records spans 29.3 percentage points from the 25th to the 75th percentile. This is more resistant to a single extreme record than the full minimum-to-maximum range.

Largest linked category

Other fruits and fruit salads

2 of 4 linked records (50%) sit in this USDA category. The remainder span 2 other categories.

Most populated share band

5% to under 15%

2 records (50%) fall in this band after repeated rows for code 9326 are combined within each food.

Most frequent eligible co-input

Melons, cantaloupe, raw

It appears alongside code 9326 in 3 linked records (75%). Co-occurrence describes database structure, not a required recipe.

Where USDA uses this input

Linked records by source-food category

Each record is counted once even if ingredient code 9326 appears on more than one input row inside that formulation. The category grouping describes the complete linked foods, not a culinary rule about the ingredient.

How the share of listed input weight changes

Repeated rows for code 9326 inside one food are combined before the percentage is calculated. The denominator is the sum of all positive-weight inputs listed for that USDA formulation.

The role changes by food type

Median listed share in the largest USDA categories

Category medians summarize source-formulation shares, not nutrient content or consumption frequency.

Listed-weight share distribution across the largest complete-food categories
Complete-food category	Records	Median	Middle 50%	Observed span
Other fruits and fruit salads	2	10.1%	9.5%–10.7%	8.9%–11.3%

What the spread can tell you

In this collection, “Watermelon, raw” ranges from 8.9% to 100% of listed source-input weight, with a median of 15.6%. That variation can help distinguish a food where the input is a small supporting component from a record where it makes up much more of the standardized source formulation.

The spread remains descriptive. It does not show uncertainty around a single recipe, and a high source-weight share does not automatically mean the food supplies more of any particular nutrient. To compare nutrients, use the complete linked records below.

Verified consumer reference

Household measures and per-100-gram nutrition for Watermelon, raw

The values here come from Watermelon, raw, the exact complete FNDDS food cited as USDA FoodData Central record 2709270. Household totals are calculated only from gram weights USDA lists for that same record.

They are not an average of this ingredient collection, and they do not transfer automatically to a different product, recipe, preparation, or portion.

A reviewed identity map connects source-input code 9326 to its unique sole-source FNDDS record.

Nutrient span across the linked foods

Every value in this table describes an entire USDA survey-food record per 100 grams. The values are not the nutrient content of ingredient code 9326, and differences cannot be attributed to this one input.

The minimum and maximum preserve the complete observed span. The median is the middle linked-record value, not a prediction for a meal and not an ingredient-specific nutrient estimate.

Method and provenance

How this ingredient-centered page was calculated

Feast begins with its pinned 3,850-record USDA FoodData Central Survey Foods reference corpus for FNDDS 2021–2023. Each exact food profile retains its FDC identifier, source-food description, nutrient values, household measures, and positive-weight input-food rows. This page groups those input rows by the exact ingredient code 9326; it does not merge similar-looking ingredient names or infer synonyms.

The distinct-record count deduplicates by FDC food record. When the same code is listed more than once inside one source formulation, its input weights are added before the listed-weight share is calculated. Category counts also count each food once. The 25th percentile, median, and 75th percentile use the sorted one-share-per-food values with linear interpolation between adjacent ranks when a percentile falls between two records.

USDA’s current FNDDS documentation explains that many nutrient profiles are generated with calculation recipes designed to represent multiple variants, and that their input codes are not necessarily the exact ingredients in a retail product or an ingredient declaration. It also documents moisture and nutrient-retention adjustments. Feast therefore treats these rows as transparent source-calculation evidence—not as a reverse-engineered recipe.

The complete-food nutrient table uses each linked record’s available published per-100-gram values so the denominator remains consistent; its middle-50% ranges use the same interpolated percentile method. It is presented for record selection and comparison only. No nutrient value is reassigned to the ingredient, no causal effect is inferred, and no “healthy” score is manufactured from the collection.

How to apply the evidence to a meal

Use the ingredient as a discovery clue. Compare the linked record names, food categories, preparation wording, source formulation, and portion measures. If a close record exists, its complete profile can provide a defensible reference estimate. If the meal differs materially in cooking fat, sauce, ingredient ratios, or portion size, keep looking or use recipe weights, a package label, or an editable photo estimate instead.

These pages are educational source indexes. They do not provide medical advice, personalized nutrient targets, food-safety guidance, or a recipe. If a clinician has given you individualized dietary instructions, follow that guidance and use the most specific current source available for the food you actually consumed.
