Roll, sour dough calories: 122 per 1 medium roll (45 g)
This exact USDA record reports 122 calories for 1 medium roll (45 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 medium roll at 45 grams. On a fixed-weight basis, the same record contains 272 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 4.9 g protein, 1 g fiber, and 271 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is bread, french or vienna (includes sourdough), 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 medium roll 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 92–155 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 2707665: “Roll, sour dough.” 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 2707665, each row multiplies the published per-100-gram values by its stated weight. “1 miniature/small roll” through “1 large roll” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 miniature/small rollUSDA-listed household measure | 34 g | 92 kcal | 3.7 g | 0.7 g | 205 mg |
| 1 medium/regular/sandwich size rollUSDA-listed household measure | 45 g | 122 kcal | 4.9 g | 1 g | 271 mg |
| 1 large rollUSDA-listed household measure | 57 g | 155 kcal | 6.2 g | 1.3 g | 343 mg |
02 · Fixed-weight context

The comparison set contains 17 exact records in the Rolls and buns USDA category. Here, “middle half” describes FDC 2707665’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 2707665’s 45 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 “Roll, sour dough,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707661 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 miniature/small roll to 1 large roll
USDA assigns those measures 34 g and 57 g. At this record’s fixed composition, scaled energy moves from 92 kcal to 155 kcal.
- 02
Record choice: compare with FDC 2707661
At an equal 100 g, this record has calories than “Roll, French or Vienna.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Bread, french or vienna (includes sourdough)
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 “sour dough” fits. Inspect FDC 2707661 when “French or Vienna” is the more literal description of the food and preparation.

Plain-English read
The six displayed nutrient values are close under a conservative materiality screen. Small differences remain exact source values, not evidence that one food is preferable.
Formulation evidence
The listed formulations match
The USDA input rows shown on these profiles are identical. The nutrient or portion distinction therefore should not be attributed to a different named input.
Shared listed inputs: Bread, french or vienna (includes sourdough).
Portion evidence
The listed portion sets differ
This record’s reference amount is 45 g; a familiar listed measure is 1 medium roll (45 g).
The comparison record’s reference amount is 45 g; a familiar listed measure is 1 medium (45 g).
Use the 100-gram row to compare FDC 2707665 with FDC 2707661 at equal mass; use their 45 g and 45 g source amounts only for portion matching.
Evidence boundary: FDC 2707665 versus FDC 2707661 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 “Roll, sour dough,” 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 2707665 comes from FoodData Central Survey Foods (FNDDS). Its 272 kcal per 100 g becomes 122 kcal at 45 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 medium roll 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: 2707665
FNDDS food code: 51159000
The scaling for FDC 2707665 can be exact while the match to “Roll, sour dough” is wrong. That is why this profile keeps its 45 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
