Bread, native, water, toasted, Puerto Rican style calories: 70 per 1 slice (23 g)
This exact USDA record reports 70 calories for 1 slice (23 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 70 calories for 1 slice at 23 grams. On a fixed-weight basis, the same record contains 306 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.6 g protein, 0.5 g fiber, and 138 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is bread, native, water, puerto rican style, representing 100% of the record’s listed input weight. 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 slice at the identical weight. We use the familiar household label here without changing the source calculation.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2707607: “Bread, native, water, toasted, Puerto Rican style.” 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 2707607, each row multiplies the published per-100-gram values by its stated weight. “75% of the reference weight” through “125% of the reference weight” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 75% of the reference weightArithmetic scenario from the reference weight | 17.3 g | 53 kcal | 2 g | 0.3 g | 103 mg |
| 1 sliceUSDA-listed household measure | 23 g | 70 kcal | 2.6 g | 0.5 g | 138 mg |
| 125% of the reference weightArithmetic scenario from the reference weight | 28.8 g | 88 kcal | 3.3 g | 0.6 g | 172 mg |

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2707607’s 23 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Iron; 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.

04 · Highest-impact checks
The three levers most worth resolving first
For “Bread, native, water, toasted, Puerto Rican style,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707606 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 23 g
A 25% weight move in either direction spans 17.3–28.8 g. When composition is held constant, those endpoints calculate to 53 kcal and 88 kcal.
- 02
Record choice: compare with FDC 2707606
At an equal 100 g, this record has 27 kcal more calories than “Bread, native, water, Puerto Rican style.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Bread, native, water, Puerto Rican style
USDA derives this record from one listed source-input row at 100 g. Real preparations can still differ in water, cooking state, brand, and served weight.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “native; water; toasted; Puerto Rican style” fits. Inspect FDC 2707606 when “native; water; Puerto Rican style” is the more literal description of the food and preparation.

Which USDA record fits your meal?
Treat the long description as data. The phrases doing the most work here are “native”, “water”, “toasted”, and “Puerto Rican style”. Match those details first; then compare the database weight with the amount you mean.
On smaller screens, focus a nutrition table and scroll horizontally to read every column.

Plain-English read
At the fixed 100-gram basis, this record lists 27 more calories than “Bread, native, water, Puerto Rican style.”
Only this record lists Bread, native, water, Puerto Rican style. Only the comparison record lists Flour, bread, white, enriched, unbleached; Beverages, water, tap, municipal; Salt, table; Leavening agents, yeast, baker's, compressed. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
1 of the six displayed differences clears the documented materiality screen. It is a reading aid, not a health rating.

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, recipe or brand, moisture and density, spreads or toppings.
For “Bread, native, water, toasted, Puerto Rican style,” 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
recipe or brand
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
moisture and density
Match the food state before matching the number. Cooking, draining, or added liquid can change grams and concentration even when the food name barely changes.
- 04
spreads or toppings
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 2707607 comes from FoodData Central Survey Foods (FNDDS). Its 306 kcal per 100 g becomes 70 kcal at 23 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 slice 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: 2707607
FNDDS food code: 51106020
The scaling for FDC 2707607 can be exact while the match to “Bread, native, water, toasted, Puerto Rican style” is wrong. That is why this profile keeps its 23 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
