What this page compares

Named source records, not one universal meal

This guide keeps 4 named USDA records in view: 4 direct matches. All sit within “Fried vegetables.” The exact descriptions remain the unit of comparison; the familiar heading is only the doorway into the evidence.

Why these records appear together: The deterministic grouping rule “normalized first description segment” placed these 4 records together under the exact grouping key “sweet potato fries.” That rule determines membership before any nutrition result is read.

For Sweet potato fries, this page can compare 4 named records from FDC 2709713 through FDC 2709714. It cannot observe which preparation was eaten, recover unnamed additions, or supply the eaten grams.

Editor’s decision brief

The three facts to carry into the table

Carry the denominator, exact identity, and strongest observed contrast into every number below.

Portion

A shared 90 g comparison anchor

Equal source weights make the selected Sweet potato fries serving totals easier to compare, but the eaten portion still has to be measured or estimated.

Composition

149 kcal separates the fixed-weight endpoints

The lower endpoint is “from fresh”; the higher is “fast food / restaurant.” This isolates density, not ingredient causation.

Discriminator

3.2 g fiber gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “from fresh” (2.8 g) and “school” (6.0 g).

Observed source examples

Three landmarks inside this source set—not universal endpoints

These 4 records each use a 90 g serving. Their serving calories compare equal weights within this set. They do not define a calorie range for every sweet potato fries; match the preparation and adjust to your portion.

Important: “Lower” begins with Sweet potato fries, from fresh; “higher” ends with Sweet potato fries, fast food / restaurant, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every sweet potato fries meal.

Full comparison

Compare every selected FNDDS record

For Sweet potato fries, serving columns preserve each record’s own listed amount, while calories per 100 g hold weight constant. A dash means the cited record does not supply that field; it does not mean the nutrient is absent.

On smaller screens, focus the table and scroll horizontally to read every column.

Portion analysis

Serving total and calorie density answer different questions

Every selected record uses a 90-gram source amount, so serving-weight differences do not explain the calorie spread inside this set. Their own source servings run from 140 calories for “from fresh” to 275 for “fast food / restaurant.” At a fixed 100 grams, “from fresh” is 156 calories and “fast food / restaurant” is 305—a fixed-weight separation of 149 calories. For Sweet potato fries, the serving view answers “how much is in the database portion?”; the 100-gram view answers “how concentrated is the matched record?” Neither reveals how many grams were actually eaten.

The scaling rule: multiply a per-100-gram value by eaten grams ÷ 100. The arithmetic is exact; the result is only as defensible as the record match and portion estimate.

Preparation analysis

The long description carries the evidence

The published descriptions distinguish forms such as “fast food / restaurant”, “from fresh”, “frozen”, and “school”. The source formulations contain 5 distinct ingredient codes; examples that appear in only part of the set include sweet potatoes, french fried, frozen as packaged, salt added in processing, salt, table, industrial oil as ingredient in food, and sweet potato, cooked, as ingredient. On this Sweet potato fries page, those rows make the records inspectable, but they are not a controlled experiment: they cannot tell us that one named input, by itself, caused a nutrient difference.

Database precision is not meal certainty. Retain the exact description beside the number so later corrections remain possible.

What changes the comparison

Four drivers worth checking before choosing a record

The family label “Sweet potato fries” cannot resolve the differences between Sweet potato fries, fast food / restaurant and Sweet potato fries, school. The four checks below identify the record wording, source weight, and formulation evidence that can.

  1. 01

    A shared source weight

    Every selected record uses 90 grams. Inside this set, serving-calorie differences therefore reflect the published composition rather than a change in source weight.

  2. 02

    The words that split the family

    Representative record-level distinctions include “fast food / restaurant”, “from fresh”, “frozen”, and “school”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    5 source-input codes appear across the selected records. Their presence and listed weights describe USDA formulations, not finished plated proportions.

  4. 04

    The unresolved plate

    Even “Sweet potato fries, fast food / restaurant” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Sweet potato fries unknowns for correction instead of converting them into false precision.

Record matching

Match identity first; scale quantity second

Read the source name as a sequence of decisions. First confirm that sweet potato fries is the right meal family. Then resolve the phrases that actually separate this set—“fast food / restaurant”, “from fresh”, “frozen”, and “school”—before comparing gram weight. If a package, menu, or known recipe provides a closer first-party description, prefer it and keep this USDA record as a transparent fallback.

A practical matching checklist

  1. Read the complete Sweet potato fries source description, including preparation and additions.
  2. Compare the listed source weight with the amount actually eaten.
  3. Prefer a current package or restaurant source when a specific branded item is known.
  4. Record toppings, sauces, cooking fat, sides, and substitutions that the selected description does not name.

Decision support from the exact records on this page

Turn source data into a better next decision

These conclusions and reading paths are computed from 4 exact records behind Sweet potato fries source-record guide. Links are chosen by record identity, controlled contrast, formulation input, nutrient spread, or serving context—not by loose keyword similarity.

Equal-weight result

Sweet potato fries, school is higher in calcium per 100 g

Sweet potato fries, school reports 55 mg versus 21 mg for Sweet potato fries, from fresh: a 34 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

These listed servings have equal weights

4 listed servings each weigh 90 g

The 4 records with a listed serving weight on this page each use 90 g. Their serving totals therefore compare equal weights, even if the household labels differ. Match the preparation and adjust the weight to the amount you eat.

Choose the record before reading the number

Sweet potato fries, fast food / restaurant and Sweet potato fries, from fresh are not interchangeable

The page keeps both records at the same 100 g denominator and makes Source form (No matching controlled term in the source name versus fresh) the explicit record-description contrast. It does not show that the wording difference caused a nutrient difference. Pick the description that matches the food in front of you rather than averaging away the distinction.
