Choose canned, cooked, or raw tuna to match what you weighed. Then enter the edible amount; a can size, a steak, and a scoop of tuna salad need different checks.

A worked portion example

The canned-tuna reference portion

Illustrative calculation: 1 standard can weighs 115 g using the linked record's portion weight. At 85 calories per 100 g, 115 × 85 ÷ 100 = about 98 calories and 21.9 g protein. This uses the example's 115 g can measure. Check your own can's label and drained-weight basis before using that amount.

For canned tuna, read the packing and serving details

The canned example uses light tuna canned in water, drained solids, and lists a standard can as 115 g. Your product may use different sizes or packing liquid. Check whether its label describes drained tuna or the contents as sold, then use the matching weight and number of servings. Oil-packed tuna needs its own product information.

Food records behind this advice

Keep raw and cooked steak weights separate

Use the raw entry for a raw tuna weight and the cooked entry for the cooked edible portion. These two entries are not a universal before-and-after conversion for the same steak. For a batch you cook yourself, keep the raw ingredient totals and divide them across the finished batch.

Food records behind this advice

Tuna salad needs the dressing too

The canned tuna entry is not a finished tuna-salad or sandwich estimate. Include mayonnaise, oil, bread, and other ingredients you used, or choose a matching complete dish. If you eat only part of a mixed batch, apply that portion to the full recipe rather than to the tuna alone.

Compare all 3 food records, nutrition tables and USDA sources

The 3 exact records in this guide report 72–158 calories in the records' own listed source servings and 85–176 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.

Across all 3 named USDA examples, a cup contains 115–238 calories. Each included example lists 135 g for that measure. The same household label can carry a different gram weight elsewhere in USDA data.

Match my meal

Start with the description closest to what you ate

For Tuna, begin by separating “Fish, tuna, canned” from “Fish, tuna, 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 3 named USDA records in view: 3 direct matches. All sit within “Fish.” 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 two description segments” placed these 3 records together under the exact grouping key “fish tuna.” That rule determines membership before any nutrition result is read.

For Tuna, this page can compare 3 named records from FDC 2706311 through FDC 2706308. 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

85–90 g before composition

The largest source amount is 1.1× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

91 kcal separates the fixed-weight endpoints

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

Discriminator

226 mg sodium gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “raw” (45 mg) and “cooked” (271 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 tuna.

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

Full comparison

Compare every selected FNDDS record

For Tuna, 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 90 grams—a 5-gram gap before composition enters the comparison. Their own source servings run from 72 calories for “canned” to 158 for “cooked.” At a fixed 100 grams, “canned” is 85 calories and “cooked” is 176—a fixed-weight separation of 91 calories. For Tuna, 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 “tuna, canned”, “tuna, cooked”, and “tuna, raw”. The source formulations contain 4 distinct ingredient codes; examples that appear in only part of the set include fish, tuna, fresh, yellowfin, raw, fish, tuna, light, canned in water, drained solids, oil or table fat, nfs, and salt, table. On this Tuna 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 “Tuna” cannot resolve the differences between Fish, tuna, canned and Fish, tuna, 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 85–90 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 “tuna, canned”, “tuna, cooked”, and “tuna, 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 “Fish, tuna, canned” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Tuna 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 tuna is the right meal family. Then resolve the phrases that actually separate this set—“tuna, canned”, “tuna, cooked”, and “tuna, 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 Tuna 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 Tuna 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

Fish, tuna, cooked is higher in total fat per 100 g

Fish, tuna, cooked reports 5.1 g versus 0.5 g for Fish, tuna, raw: a 4.6 g difference when both are normalized to 100 g.

Inspect the underlying evidence

Check the weight before comparing serving totals

Source amounts span 85–90 g

Fish, tuna, canned uses USDA source amount (85 g), while Fish, tuna, cooked uses USDA source amount (90 g). Use per 100 g for equal-weight composition; use the serving column only when those named source amounts answer your question.

Record identity is part of the estimate

Distinguish “Fish, tuna, canned” from “Fish, tuna, raw”

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.
