Compare all 5 food records, nutrition tables and USDA sources

The 5 exact records in this guide report 8–40 calories in the records' own listed source servings and 19–53 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.

Match my meal

Start with the description closest to what you ate

For Mustard greens, begin by separating “Mustard greens, fresh, cooked, fat added” from “Mustard greens, raw.” Choosing a card filters this source set; it does not infer the portion or fill in ingredients the chosen description does not name.

What this page compares

Named source records, not one universal meal

This guide keeps 5 named USDA records in view: 5 direct matches. All sit within “Other dark green vegetables.” The exact descriptions remain the unit of comparison; the familiar heading is only the doorway into the evidence.

Why these records appear together: The deterministic grouping rule “normalized first description segment” placed these 5 records together under the exact grouping key “mustard greens.” That rule determines membership before any nutrition result is read.

For Mustard greens, this page can compare 5 named records from FDC 2709610 through FDC 2709606. It cannot observe which preparation was eaten, recover unnamed additions, or supply the eaten grams.

Editor’s decision brief

The three facts to carry into the table

Carry the denominator, exact identity, and strongest observed contrast into every number below.

Portion

28–85 g before composition

The largest source amount is 3.0× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

34 kcal separates the fixed-weight endpoints

The lower endpoint is “frozen, cooked, no added fat”; the higher is “fresh, cooked, fat added.” This isolates density, not ingredient causation.

Discriminator

131 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “raw” (20 mg) and “fresh, cooked, fat added” (151 mg).

Observed source examples

Three landmarks inside this source set—not universal endpoints

The cards are ordered by calories in each record's listed serving. Serving weights differ, so use per-100-gram values to compare composition. These selected records do not define a calorie range for every mustard greens.

Important: “Lower” begins with Mustard greens, raw; “higher” ends with Mustard greens, fresh, cooked, fat added, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every mustard greens meal.

Full comparison

Compare every selected FNDDS record

For Mustard greens, serving columns preserve each record’s own listed amount, while calories per 100 g hold weight constant. A dash means the cited record does not supply that field; it does not mean the nutrient is absent.

On smaller screens, focus the table and scroll horizontally to read every column.

Portion analysis

Serving total and calorie density answer different questions

The listed source amounts run from 28 to 85 grams—a 57-gram gap before composition enters the comparison. Their own source servings run from 8 calories for “raw” to 40 for “fresh, cooked, fat added.” At a fixed 100 grams, “frozen, cooked, no added fat” is 19 calories and “fresh, cooked, fat added” is 53—a fixed-weight separation of 34 calories. For Mustard greens, the serving view answers “how much is in the database portion?”; the 100-gram view answers “how concentrated is the matched record?” Neither reveals how many grams were actually eaten.

The scaling rule: multiply a per-100-gram value by eaten grams ÷ 100. The arithmetic is exact; the result is only as defensible as the record match and portion estimate.

Preparation analysis

The long description carries the evidence

The published descriptions distinguish forms such as “fresh, cooked, fat added”, “fresh, cooked, no added fat”, “frozen, cooked, fat added”, “frozen, cooked, no added fat”, and “raw”. The source formulations contain 4 distinct ingredient codes; examples that appear in only part of the set include salt, table, mustard greens, raw, mustard greens, frozen, cooked, boiled, drained, without salt, and oil or table fat, nfs. On this Mustard greens page, those rows make the records inspectable, but they are not a controlled experiment: they cannot tell us that one named input, by itself, caused a nutrient difference.

Database precision is not meal certainty. Retain the exact description beside the number so later corrections remain possible.

What changes the comparison

Four drivers worth checking before choosing a record

The family label “Mustard greens” cannot resolve the differences between Mustard greens, fresh, cooked, fat added and Mustard greens, raw. The four checks below identify the record wording, source weight, and formulation evidence that can.

  1. 01

    Source weight before serving calories

    The source amounts span 28–85 grams. Compare per 100 grams before reading a serving-calorie gap as a composition gap.

  2. 02

    The words that split the family

    Representative record-level distinctions include “fresh, cooked, fat added”, “fresh, cooked, no added fat”, “frozen, cooked, fat added”, “frozen, cooked, no added fat”, and “raw”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    4 source-input codes appear across the selected records. Their presence and listed weights describe USDA formulations, not finished plated proportions.

  4. 04

    The unresolved plate

    Even “Mustard greens, fresh, cooked, fat added” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Mustard greens unknowns for correction instead of converting them into false precision.

Record matching

Match identity first; scale quantity second

Read the source name as a sequence of decisions. First confirm that mustard greens is the right meal family. Then resolve the phrases that actually separate this set—“fresh, cooked, fat added”, “fresh, cooked, no added fat”, “frozen, cooked, no added fat”, and “raw”—before comparing gram weight. If a package, menu, or known recipe provides a closer first-party description, prefer it and keep this USDA record as a transparent fallback.

A practical matching checklist

  1. Read the complete Mustard greens source description, including preparation and additions.
  2. Compare the listed source weight with the amount actually eaten.
  3. Prefer a current package or restaurant source when a specific branded item is known.
  4. Record toppings, sauces, cooking fat, sides, and substitutions that the selected description does not name.

Decision support from the exact records on this page

Turn source data into a better next decision

These conclusions and reading paths are computed from 5 exact records behind Mustard greens source-record guide. Links are chosen by record identity, controlled contrast, formulation input, nutrient spread, or serving context—not by loose keyword similarity.

Equal-weight result

Mustard greens, fresh, cooked, fat added is higher in total fat per 100 g

Mustard greens, fresh, cooked, fat added reports 3.2 g versus 0.3 g for Mustard greens, frozen, cooked, no added fat: a 2.9 g difference when both are normalized to 100 g.

Inspect the underlying evidence

The denominator changes the answer

Mustard greens, raw is denser; Mustard greens, frozen, cooked, no added fat is higher in its source amount

Mustard greens, raw reports 27 kcal per 100 g and 8 kcal in USDA source amount (28 g). Mustard greens, frozen, cooked, no added fat reports a lower 19 kcal per 100 g but a higher 16 kcal in USDA source amount (83 g).

Choose the record before reading the number

Mustard greens, fresh, cooked, fat added and Mustard greens, raw are not interchangeable

The page keeps both records at the same 100 g denominator and makes Preparation wording (No matching controlled term in the source name versus raw) the explicit record-description contrast. It does not show that the wording difference caused a nutrient difference. Pick the description that matches the food in front of you rather than averaging away the distinction.
