Potato chips, unsalted calories: 150 per 1 small bag (28 g)
This exact USDA record reports 150 calories for 1 small bag (28 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 150 calories for 1 small bag at 28 grams. On a fixed-weight basis, the same record contains 537 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 1.8 g protein, 1.5 g fiber, and 2 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is potato chips, without salt, reduced fat, representing 88% of the record’s listed input weight. The record contains 2 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 bag 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 11–456 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 2709438: “Potato chips, unsalted.” 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 2709438, each row multiplies the published per-100-gram values by its stated weight. “1 chip” through “1 large single serving bag” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 chipUSDA-listed household measure | 2 g | 11 kcal | 0.1 g | 0.1 g | 0 mg |
| 1 small single serving bagUSDA-listed household measure | 28 g | 150 kcal | 1.8 g | 1.5 g | 2 mg |
| 1 large single serving bagUSDA-listed household measure | 85 g | 456 kcal | 5.3 g | 4.6 g | 6 mg |
02 · Fixed-weight context

The strongest strength-side and tradeoff-side signals
At FDC 2709438’s 28 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Potassium; the larger tradeoff-side percentage is Saturated fat. 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 “Potato chips, unsalted,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709422 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 chip to 1 large single serving bag
USDA assigns those measures 2 g and 85 g. At this record’s fixed composition, scaled energy moves from 11 kcal to 456 kcal.
- 02
Record choice: compare with FDC 2709422
At an equal 100 g, this record has 520 mg less sodium than “Potato chips, plain.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Potato chips, without salt, reduced fat
The source formulation has 2 input rows; Potato chips, without salt, reduced fat supplies 88% 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 “unsalted” fits. Inspect FDC 2709422 when “plain” is the more literal description of the food and preparation.

Only this record lists Potato chips, without salt, reduced fat; Oil, corn. Only the comparison record lists Snacks, potato chips, plain, salted. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
3 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.
Listed only in this record: Potato chips, without salt, reduced fat; Oil, corn.

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 piece or portion size, recipe or brand, fillings or frosting, added fats and sugars.
For “Potato chips, unsalted,” resolve piece or portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
piece or portion 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
fillings or frosting
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
added fats and sugars
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2709438 comes from FoodData Central Survey Foods (FNDDS). Its 537 kcal per 100 g becomes 150 kcal at 28 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 bag 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: 2709438
FNDDS food code: 71202000
The scaling for FDC 2709438 can be exact while the match to “Potato chips, unsalted” is wrong. That is why this profile keeps its 28 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
