Liver calories per cup: 218–265 across all 3 named USDA examples

Across all 3 named USDA examples, a cup contains 218–265 calories. Their listed weights span 125–202 g, so each calorie value is calculated from that example's own gram weight and published calories per 100 g.

Compare all 3 food records, nutrition tables and USDA sources

The 3 exact records in this guide report 148–195 calories in the records' own listed source servings and 129–189 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 Liver, begin by separating “Liver, beef” from “Liver, chicken.” 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 3 named USDA records in view: 3 direct matches. They span 2 source categories, including Liver and organ meats and Meat mixed dishes. 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 3 records together under the exact grouping key “liver.” That rule determines membership before any nutrition result is read.

For Liver, this page can compare 3 named records from FDC 2706153 through FDC 2706154. 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

85–151 g before composition

The largest source amount is 1.8× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

60 kcal separates the fixed-weight endpoints

The lower endpoint is “beef or calves; and onions”; the higher is “chicken.” This isolates density, not ingredient causation.

Discriminator

177 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “beef or calves; and onions” (276 mg) and “chicken” (453 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 liver.

Important: “Lower” begins with Liver, beef; “higher” ends with Liver, beef or calves, and onions, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every liver meal.

Full comparison

Compare every selected FNDDS record

For Liver, 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 85 to 151 grams—a 66-gram gap before composition enters the comparison. Their own source servings run from 148 calories for “beef” to 195 for “beef or calves; and onions.” At a fixed 100 grams, “beef or calves; and onions” is 129 calories and “chicken” is 189—a fixed-weight separation of 60 calories. For Liver, 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 “beef”, “beef or calves, and onions”, and “chicken”. Across the source formulations, the shared backbone includes salt, table; differentiating rows include beef, variety meats and by-products, liver, cooked, pan-fried, chicken, liver, all classes, raw, flour, wheat, all-purpose, enriched, bleached, and margarine, stick. On this Liver 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 “Liver” cannot resolve the differences between Liver, beef and Liver, chicken. 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 85–151 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 “beef”, “beef or calves, and onions”, and “chicken”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    Shared source rows include salt, table; rows that vary across the set include beef, variety meats and by-products, liver, cooked, pan-fried, chicken, liver, all classes, raw, and flour, wheat, all-purpose, enriched, bleached. Presence is inspectable evidence, not proof of nutrient causation.

  4. 04

    The unresolved plate

    Even “Liver, beef” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Liver 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 liver is the right meal family. Then resolve the phrases that actually separate this set—“beef”, “beef or calves, and onions”, and “chicken”—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 Liver 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 3 exact records behind Liver 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

Liver, beef is higher in vitamin D per 100 g

Liver, beef reports 1.2 µg versus 0 µg for Liver, chicken: a 1.2 µg difference when both are normalized to 100 g.

Inspect the underlying evidence

The denominator changes the answer

Liver, beef is denser; Liver, beef or calves, and onions is higher in its source amount

Liver, beef reports 174 kcal per 100 g and 148 kcal in USDA source amount (85 g). Liver, beef or calves, and onions reports a lower 129 kcal per 100 g but a higher 195 kcal in USDA source amount (151 g).

Record identity is part of the estimate

Distinguish “Liver, beef” from “Liver, chicken”

These are separate USDA records with separate formulations or survey descriptions. Match preparation, additions, and the named household amount before borrowing either record’s nutrients.
