Start with the description closest to what you ate

For Potato, mashed, begin by separating “Potato, mashed, from fast food” from “Potato, mashed, ready-to-heat, with gravy.” Choosing a card filters this source set; it does not infer the portion or fill in ingredients the chosen description does not name.

What this page compares

Named source records, not one universal meal

This guide keeps 11 named USDA records in view: 11 direct matches. All sit within “Mashed potatoes and white potato mixtures.” 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 two description segments” placed these 11 records together under the exact grouping key “potato mashed.” That rule determines membership before any nutrition result is read.

For Potato, mashed, this page can compare 11 named records from FDC 2709493 through FDC 2709509. 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 125 g comparison anchor

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

Composition

68 kcal separates the fixed-weight endpoints

The lower endpoint is “from school lunch”; the higher is “mashed, from fresh, made with milk, with cheese.” This isolates density, not ingredient causation.

Discriminator

3.0 g protein gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “mashed, from fast food, with gravy” (1.5 g) and “mashed, from fresh, made with milk, with cheese” (4.4 g).

Observed source examples

Three landmarks inside this source set—not universal endpoints

These 11 records each use a 125 g serving. Their serving calories compare equal weights within this set. They do not define a calorie range for every potato, mashed; match the preparation and adjust to your portion.

Important: “Lower” begins with Potato, mashed, from school lunch; “higher” ends with Potato, mashed, from fresh, made with milk, with cheese, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every potato, mashed meal.

Full comparison

Compare every selected FNDDS record

For Potato, mashed, 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 125-gram source amount, so serving-weight differences do not explain the calorie spread inside this set. Their own source servings run from 96 calories for “from school lunch” to 181 for “mashed, from fresh, made with milk, with cheese.” At a fixed 100 grams, “from school lunch” is 77 calories and “mashed, from fresh, made with milk, with cheese” is 145—a fixed-weight separation of 68 calories. For Potato, mashed, 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 “mashed, from fast food”, “mashed, from fresh, made with milk, with cheese”, “mashed, from restaurant”, “mashed, ready-to-heat”, and “mashed, ready-to-heat, with gravy”. The source formulations contain 14 distinct ingredient codes; examples that appear in only part of the set include gravy, chicken, canned or bottled, ready-to-serve, potatoes, mashed, ready-to-eat, salt, table, and cheese, cheddar. On this Potato, mashed 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 “Potato, mashed” cannot resolve the differences between Potato, mashed, from fast food and Potato, mashed, ready-to-heat, with gravy. 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 125 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 “mashed, from fast food”, “mashed, from fresh, made with milk, with cheese”, “mashed, from restaurant”, “mashed, ready-to-heat”, and “mashed, ready-to-heat, with gravy”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    14 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 “Potato, mashed, from fast food” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Potato, mashed 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 potato, mashed is the right meal family. Then resolve the phrases that actually separate this set—“mashed, from fast food”, “mashed, from fresh, made with milk, with cheese”, “mashed, from school lunch”, and “mashed, ready-to-heat, with gravy”—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 Potato, mashed 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 11 exact records behind Potato, mashed 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

Potato, mashed, ready-to-heat, with cheese is higher in calcium per 100 g

Potato, mashed, ready-to-heat, with cheese reports 106 mg versus 16 mg for Potato, mashed, from fast food, with gravy: a 90 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

These listed servings have equal weights

11 listed servings each weigh 125 g

The 11 records with a listed serving weight on this page each use 125 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

Potato, mashed, from fresh, made with milk, with gravy and Potato, mashed, from restaurant, with gravy are not interchangeable

The page keeps both records at the same 100 g denominator and makes Source form (fresh versus No matching controlled term in the source name) 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.
