Potato chips, plain calories: 149 per 1 small bag (28 g)
This exact USDA record reports 149 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 149 calories for 1 small bag at 28 grams. On a fixed-weight basis, the same record contains 532 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, 0.9 g fiber, and 148 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is snacks, potato chips, plain, salted, 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 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 11–452 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 2709422: “Potato chips, plain.” 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 2709422, 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 | 11 mg |
| 1 small single serving bagUSDA-listed household measure | 28 g | 149 kcal | 1.8 g | 0.9 g | 148 mg |
| 1 large single serving bagUSDA-listed household measure | 85 g | 452 kcal | 5.4 g | 2.6 g | 448 mg |
02 · Fixed-weight context

The strongest strength-side and tradeoff-side signals
At FDC 2709422’s 28 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Potassium; 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 “Potato chips, plain,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709427 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 452 kcal.
- 02
Record choice: compare with FDC 2709427
At an equal 100 g, this record has calories than “Potato chips, ruffled, plain.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Snacks, potato chips, plain, salted
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 “plain” fits. Inspect FDC 2709427 when “ruffled; plain” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2709422 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Potato chips, plain” inspectable beside similarly named records.
How to read this
A single-source formulation
Snacks, potato chips, plain, salted is the only listed source input for this record. That does not mean every real-world version is identical; brands, preparation, water content, and portion weight can still differ.

Exact-record context
What makes this USDA record distinct?
For FDC 2709422, the close-record rule searches the USDA “Potato chips” 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
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: Snacks, potato chips, plain, salted.
Portion evidence
The listed portion sets differ
This record’s reference amount is 28 g; a familiar listed measure is 1 small bag (28 g).
The comparison record’s reference amount is 28 g; a familiar listed measure is 1 small bag (28 g).
Use the 100-gram row to compare FDC 2709422 with FDC 2709427 at equal mass; use their 28 g and 28 g source amounts only for portion matching.
Evidence boundary: FDC 2709422 versus FDC 2709427 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 piece or portion size, recipe or brand, fillings or frosting, added fats and sugars.
For “Potato chips, plain,” 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 2709422 comes from FoodData Central Survey Foods (FNDDS). Its 532 kcal per 100 g becomes 149 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: 2709422
FNDDS food code: 71200100
The scaling for FDC 2709422 can be exact while the match to “Potato chips, plain” is wrong. That is why this profile keeps its 28 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
