The editorial read

The useful answer has a weight, a composition, and an identity

Portion: the cited record reports about 142 calories for 1 cup at 30 grams. On a fixed-weight basis, the same record contains 472 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.

Composition: that source amount also reports 2.1 g protein, 1.6 g fiber, and 98 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.

Identity: the largest listed formulation input is snacks, tortilla chips, plain, white corn, 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 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 14–401 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 2708202: “Tortilla 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 2708202, 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.

03 · FDA label lens

The strongest strength-side and tradeoff-side signals

At FDC 2708202’s 30 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.

Strength-side signals

Magnesium25 mg

≈ 6% DV. This does not cross the FDA’s 20% ‘high’ guide.

Dietary fiber1.6 g

04 · Highest-impact checks

The three levers most worth resolving first

For “Tortilla chips, plain,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708204 alternative, and its source-formulation identity.

  1. 01

    Listed portion span: 1 chip to 1 large single serving bag

    USDA assigns those measures 3 g and 85 g. At this record’s fixed composition, scaled energy moves from 14 kcal to 401 kcal.

  2. 02

    Record choice: compare with FDC 2708204

    At an equal 100 g, this record has 363 mg less sodium than “Tortilla chips, flavored.” That is a record-level contrast; it does not identify which ingredient caused the difference.

  3. 03

    Single listed source: Snacks, tortilla chips, plain, white corn, 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 2708204 when “flavored” is the more literal description of the food and preparation.

Inside the source record

Source formulation behind this USDA record

USDA links FDC 2708202 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Tortilla chips, plain” inspectable beside similarly named records.

How to read this

A single-source formulation

Snacks, tortilla chips, plain, white corn, 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.

100 g total listed input weight across the formulation.

Use this formulation to choose a closer record—not to reverse-engineer a recipe. If your meal adds, removes, or substantially changes one of these components, another source entry or a photo-based estimate may fit better.

Exact-record context

What makes this USDA record distinct?

For FDC 2708202, the close-record rule searches the USDA “Tortilla, corn, other 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

At the fixed 100-gram basis, this record lists 47 less calories, 7 g more carbohydrate, and 6.7 g less total fat than “Tortilla chips, flavored.”

Only this record lists Snacks, tortilla chips, plain, white corn, salted. Only the comparison record lists Snacks, tortilla chips, nacho cheese. 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.

Listed only in this record: Snacks, tortilla chips, plain, white corn, salted.

Portion evidence

The listed portion sets match

This record’s reference amount is 30 g; a familiar listed measure is 1 cup (30 g).

The comparison record’s reference amount is 30 g; a familiar listed measure is 1 cup (30 g).

Use the 100-gram row to compare FDC 2708202 with FDC 2708204 at equal mass; use their 30 g and 30 g source amounts only for portion matching.

Evidence boundary: FDC 2708202 versus FDC 2708204 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 “Tortilla 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.

  1. 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.

  2. 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.

  3. 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.

  4. 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 2708202 comes from FoodData Central Survey Foods (FNDDS). Its 472 kcal per 100 g becomes 142 kcal at 30 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: 2708202

FNDDS food code: 54401075

The scaling for FDC 2708202 can be exact while the match to “Tortilla chips, plain” is wrong. That is why this profile keeps its 30 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
