Taco, fish calories: 275 per 1 small/regular (100 g)
This exact USDA record reports 275 calories for 1 small/regular (100 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 275 calories for 1 small/regular at 100 grams. On a fixed-weight basis, the same record contains 275 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 11.6 g protein, 2.5 g fiber, and 447 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is fish, ns as to type, fried, representing 59.7% of the record’s listed input weight. The record contains 4 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 small/regular at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 138–413 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.
Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2708529: “Taco, fish.” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.
01 · Portion arithmetic
Three weights, one fixed composition
For FDC 2708529, each row multiplies the published per-100-gram values by its stated weight. “1 miniature” through “1 large” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 miniatureUSDA-listed household measure | 50 g | 138 kcal | 5.8 g | 1.3 g | 224 mg |
| 1 small/regularUSDA-listed household measure | 100 g | 275 kcal | 11.6 g | 2.5 g | 447 mg |
| 1 largeUSDA-listed household measure | 150 g | 413 kcal | 17.4 g | 3.8 g | 671 mg |

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2708529’s 100 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Vitamin D; the larger tradeoff-side percentage is Sodium. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.

≈ 13% DV. This does not cross the FDA’s 20% ‘high’ guide.

04 · Highest-impact checks
The three levers most worth resolving first
For “Taco, fish,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708532 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 miniature to 1 large
USDA assigns those measures 50 g and 150 g. At this record’s fixed composition, scaled energy moves from 138 kcal to 413 kcal.
- 02
Record choice: compare with FDC 2708532
At an equal 100 g, this record has 9.1 g more total fat than “Taco, with beans, no cheese.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Fish, NS as to type, fried
The source formulation has 4 input rows; Fish, NS as to type, fried supplies 59.7% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “fish” fits. Inspect FDC 2708532 when “with beans; no cheese” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2708529 to 4 source inputs totaling 100.5 g in its standardized formulation. Publishing that exact provenance makes “Taco, fish” inspectable beside similarly named records.
How to read this
4 listed components
The largest listed inputs by source weight are Fish, NS as to type, fried, Tortillas, ready-to-bake or -fry, corn, Vegetable oil, NFS. The order and weights below come from the standardized USDA formulation, so they offer context for this exact database entry.

USDA shorthand in this evidence
- NFS means “not further specified.” The record intentionally leaves the exact subtype, size, or preparation unresolved.
- NS as to… means “not specified as to…” the detail that follows. It preserves an unknown distinction; it does not mean the ingredient or characteristic is absent.
Exact-record context
What makes this USDA record distinct?
For FDC 2708529, the close-record rule searches the USDA “Burritos and tacos” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

Plain-English read
At the fixed 100-gram basis, this record lists 108 more calories, 6.6 g more protein, and 9.1 g more total fat than “Taco, with beans, no cheese.”
Only this record lists Fish, NS as to type, fried. Only the comparison record lists Refried beans, canned, traditional, reduced sodium. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
4 of the six displayed differences clear the documented materiality screen. It is a reading aid, not a health rating.
Formulation evidence
The listed formulations differ
The formulation rows differ, but the source data do not isolate which component caused any nutrient difference. Input weights describe the standardized formulation—not final plated proportions.
Shared listed inputs: Tortillas, ready-to-bake or -fry, corn; Vegetable oil, NFS; Salt, table.
Listed only in this record: Fish, NS as to type, fried.
Listed only in the comparison: Refried beans, canned, traditional, reduced sodium.
Portion evidence
The listed portion sets match
This record’s reference amount is 100 g; a familiar listed measure is 1 small/regular (100 g).
The comparison record’s reference amount is 100 g; a familiar listed measure is 1 small/regular (100 g).
Use the 100-gram row to compare FDC 2708529 with FDC 2708532 at equal mass; use their 100 g and 100 g source amounts only for portion matching.
Evidence boundary: FDC 2708529 versus FDC 2708532 is a comparison of standardized source records—not a measurement of your meal, an overall food-quality rank, or proof that one input caused a difference.

Uncertainty, made actionable
What can change this estimate?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with item size, bread or wrapper size, fillings, sauces and cheese.
For “Taco, fish,” resolve item size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
item size
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
- 02
bread or wrapper size
Resolve bread or wrapper size only when the meal or its source gives you evidence. If it is unknown, leave the uncertainty visible instead of choosing the most convenient variant.
- 03
fillings
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
- 04
sauces and cheese
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2708529 comes from FoodData Central Survey Foods (FNDDS). Its 275 kcal per 100 g becomes 275 kcal at 100 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.
About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 small/regular has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2708529
FNDDS food code: 58102210
The scaling for FDC 2708529 can be exact while the match to “Taco, fish” is wrong. That is why this profile keeps its 100 g weight, 4-row source formulation, and selection uncertainty beside the arithmetic.
