Compare all 2 food records, nutrition tables and USDA sources

The 2 exact records in this guide report 8–48 calories in the records' own listed source servings and 31–62 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 Fennel bulb, begin by separating “Fennel bulb, cooked” from “Fennel bulb, 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 2 named USDA records in view: 2 direct matches. All sit within “Other vegetables and combinations.” 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 2 records together under the exact grouping key “fennel bulb.” That rule determines membership before any nutrition result is read.

For Fennel bulb, this page can compare 2 named records from FDC 2709907 through FDC 2709779. 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

25–78 g before composition

The largest source amount is 3.1× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

31 kcal separates the fixed-weight endpoints

The lower endpoint is “raw”; the higher is “cooked.” This isolates density, not ingredient causation.

Discriminator

150 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “raw” (52 mg) and “cooked” (202 mg).

Observed source examples

Both records, with their own serving weights intact

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 fennel bulb.

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

Full comparison

Compare every selected FNDDS record

For Fennel bulb, 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 25 to 78 grams—a 53-gram gap before composition enters the comparison. Their own source servings run from 8 calories for “raw” to 48 for “cooked.” At a fixed 100 grams, “raw” is 31 calories and “cooked” is 62—a fixed-weight separation of 31 calories. For Fennel bulb, 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 “cooked” and “raw”. Across the source formulations, the shared backbone includes fennel, bulb, raw; differentiating rows include oil or table fat, nfs and salt, table. On this Fennel bulb 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 “Fennel bulb” cannot resolve the differences between Fennel bulb, cooked and Fennel bulb, 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 25–78 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 “cooked” and “raw”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    Shared source rows include fennel, bulb, raw; rows that vary across the set include oil or table fat, nfs and salt, table. Presence is inspectable evidence, not proof of nutrient causation.

  4. 04

    The unresolved plate

    Even “Fennel bulb, cooked” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Fennel bulb 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 fennel bulb is the right meal family. Then resolve the phrases that actually separate this set—“cooked” 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 Fennel bulb 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 2 exact records behind Fennel bulb 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

Fennel bulb, cooked is higher in total fat per 100 g

Fennel bulb, cooked reports 3.2 g versus 0.2 g for Fennel bulb, raw: a 3 g difference when both are normalized to 100 g.

Inspect the underlying evidence

Check the weight before comparing serving totals

Source amounts span 25–78 g

Fennel bulb, raw uses USDA source amount (25 g), while Fennel bulb, cooked uses USDA source amount (78 g). Use per 100 g for equal-weight composition; use the serving column only when those named source amounts answer your question.

Choose the record before reading the number

Fennel bulb, cooked and Fennel bulb, 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.
