Bread, zucchini calories: 122 per 1 slice (40 g)
This exact USDA record reports 122 calories for 1 slice (40 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 122 calories for 1 slice at 40 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 g protein, 0.4 g fiber, and 116 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is flour, wheat, all-purpose, enriched, bleached, representing 21.4% of the record’s listed input weight. The record contains 10 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 slice 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 20–122 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 2707851: “Bread, zucchini.” 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 2707851, each row multiplies the published per-100-gram values by its stated weight. “1 cubic inch” through “1 slice” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 cubic inchUSDA-listed household measure | 6.6 g | 20 kcal | 0.3 g | 0.1 g | 19 mg |
| 75% of the reference weightArithmetic scenario from the reference weight | 30 g | 92 kcal | 1.5 g | 0.3 g | 87 mg |
| 1 sliceUSDA-listed household measure | 40 g | 122 kcal | 2 g | 0.4 g | 116 mg |
02 · Fixed-weight context
Where 100 grams sits inside Biscuits, muffins, quick breads
The comparison set contains 34 exact records in the Biscuits, muffins, quick breads USDA category. Here, “middle half” describes FDC 2707851’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2707851’s 40 g reference weight, none of the compatible strength-side nutrients evaluated here reaches 5% Daily Value; 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.
Strength-side signals
No compatible strength-side nutrient evaluated here reaches 5% DV at this reference weight, so this page does not manufacture a “strength” from a negligible percentage.
Tradeoff-side signals
Sodium116 mg
≈ 5% DV. This does not cross the FDA’s 20% ‘high’ guide.
Saturated fat0.9 g
≈ 4% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Bread, zucchini,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707848 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 cubic inch to 1 slice
USDA assigns those measures 6.6 g and 40 g. At this record’s fixed composition, scaled energy moves from 20 kcal to 122 kcal.
- 02
Record choice: compare with FDC 2707848
At an equal 100 g, this record has 7 g less total fat than “Bread, nut.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Flour, wheat, all-purpose, enriched, bleached
The source formulation has 10 input rows; Flour, wheat, all-purpose, enriched, bleached supplies 21.4% 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 “zucchini” fits. Inspect FDC 2707848 when “nut” is the more literal description of the food and preparation.

USDA shorthand in this evidence
- NFS means “not further specified.” The record intentionally leaves the exact subtype, size, or preparation unresolved.
Exact-record context
What makes this USDA record distinct?
For FDC 2707851, the close-record rule searches the USDA “Biscuits, muffins, quick breads” 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 97 less calories, 1.5 g less protein, and 7.1 g less carbohydrate than “Bread, nut.”
Only this record lists Squash, summer, zucchini, includes skin, raw. Only the comparison record lists Nuts, walnuts, English, halves, raw. 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: Flour, wheat, all-purpose, enriched, bleached; Leavening agents, baking powder, double-acting, sodium aluminum sulfate; Salt, table; Eggs, Grade A, Large, egg whole; and 5 more.
Listed only in this record: Squash, summer, zucchini, includes skin, raw.
Listed only in the comparison: Nuts, walnuts, English, halves, raw.
Portion evidence
The listed portion sets differ
This record’s reference amount is 40 g; a familiar listed measure is 1 slice (40 g).
The comparison record’s reference amount is 49 g; a familiar listed measure is 1 slice (49 g).
Use the 100-gram row to compare FDC 2707851 with FDC 2707848 at equal mass; use their 40 g and 49 g source amounts only for portion matching.
Evidence boundary: FDC 2707851 versus FDC 2707848 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, recipe or brand, moisture and density, spreads or toppings.
For “Bread, zucchini,” 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 2707851 comes from FoodData Central Survey Foods (FNDDS). Its 306 kcal per 100 g becomes 122 kcal at 40 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: 2707851
FNDDS food code: 52407000
The scaling for FDC 2707851 can be exact while the match to “Bread, zucchini” is wrong. That is why this profile keeps its 40 g weight, 10-row source formulation, and selection uncertainty beside the arithmetic.
