The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 243 calories for 1 cup at 45 grams. On a fixed-weight basis, the same record contains 539 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.8 g protein, 1.8 g fiber, and 231 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is snacks, corn-based, extruded, chips, plain, 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 cup 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 5–458 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 2708198: “Corn chips, plain (Fritos).” 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 2708198, 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 | 1 g | 5 kcal | 0.1 g | 0 g | 5 mg |
| 1 cupUSDA-listed household measure | 45 g | 243 kcal | 2.8 g | 1.8 g | 231 mg |
| 1 large single serving bagUSDA-listed household measure | 85 g | 458 kcal | 5.2 g | 3.4 g | 437 mg |

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2708198’s 45 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Magnesium; 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 “Corn chips, plain (Fritos),” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708199 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 chip to 1 large single serving bag
USDA assigns those measures 1 g and 85 g. At this record’s fixed composition, scaled energy moves from 5 kcal to 458 kcal.
- 02
Record choice: compare with FDC 2708199
At an equal 100 g, this record has 190 mg less sodium than “Corn chips, flavored (Fritos).” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Snacks, corn-based, extruded, chips, plain
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 (Fritos)” fits. Inspect FDC 2708199 when “flavored (Fritos)” is the more literal description of the food and preparation.

Plain-English read
At the fixed 100-gram basis, this record lists 190 mg less sodium than “Corn chips, flavored (Fritos).”
Only the comparison record lists Salt, table. 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.
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: Snacks, corn-based, extruded, chips, plain.
Listed only in the comparison: Salt, table.
Portion evidence
The listed portion sets match
This record’s reference amount is 45 g; a familiar listed measure is 1 cup (45 g).
The comparison record’s reference amount is 45 g; a familiar listed measure is 1 cup (45 g).
Use the 100-gram row to compare FDC 2708198 with FDC 2708199 at equal mass; use their 45 g and 45 g source amounts only for portion matching.
Evidence boundary: FDC 2708198 versus FDC 2708199 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 “Corn chips, plain (Fritos),” 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 2708198 comes from FoodData Central Survey Foods (FNDDS). Its 539 kcal per 100 g becomes 243 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 cup 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: 2708198
FNDDS food code: 54401031
The scaling for FDC 2708198 can be exact while the match to “Corn chips, plain (Fritos)” is wrong. That is why this profile keeps its 45 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
