Compare all 4 food records, nutrition tables and USDA sources

The 4 exact records in this guide report 7–61 calories in the records' own listed source servings and 64–680 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.

Match my meal

Start with the description closest to what you ate

For Mayonnaise, begin by separating “Mayonnaise, fat free” from “Mayonnaise, regular.” 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 4 named USDA records in view: 4 direct matches. All sit within “Mayonnaise.” 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 “mayonnaise.” That rule determines membership before any nutrition result is read.

For Mayonnaise, this page can compare 4 named records from FDC 2710235 through FDC 2710204. 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

9–11 g before composition

The largest source amount is 1.2× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

616 kcal separates the fixed-weight endpoints

The lower endpoint is “fat free”; the higher is “regular.” This isolates density, not ingredient causation.

Discriminator

2.0 g fiber gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “light” (0.0 g) and “fat free” (2.0 g).

Observed source examples

Three landmarks inside this source set—not universal endpoints

The cards are ordered by calories in each record's listed serving. Serving weights differ, so use per-100-gram values to compare composition. These selected records do not define a calorie range for every mayonnaise.

Important: “Lower” begins with Mayonnaise, fat free; “higher” ends with Mayonnaise, regular, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every mayonnaise meal.

Full comparison

Compare every selected FNDDS record

For Mayonnaise, 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

The listed source amounts run from 9 to 11 grams—a 2-gram gap before composition enters the comparison. Their own source servings run from 7 calories for “fat free” to 61 for “regular.” At a fixed 100 grams, “fat free” is 64 calories and “regular” is 680—a fixed-weight separation of 616 calories. For Mayonnaise, 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 “fat free”, “light”, “reduced fat, with olive oil”, and “regular”. The source formulations contain 4 distinct ingredient codes; examples that appear in only part of the set include mayonnaise, reduced fat, with olive oil, salad dressing, kraft mayo fat free mayonnaise dressing, salad dressing, mayonnaise, light, and salad dressing, mayonnaise, regular. On this Mayonnaise 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 “Mayonnaise” cannot resolve the differences between Mayonnaise, fat free and Mayonnaise, regular. The four checks below identify the record wording, source weight, and formulation evidence that can.

  1. 01

    Source weight before serving calories

    The source amounts span 9–11 grams. Compare per 100 grams before reading a serving-calorie gap as a composition gap.

  2. 02

    The words that split the family

    Representative record-level distinctions include “fat free”, “light”, “reduced fat, with olive oil”, and “regular”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    4 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 “Mayonnaise, fat free” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Mayonnaise 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 mayonnaise is the right meal family. Then resolve the phrases that actually separate this set—“fat free”, “light”, “reduced fat, with olive oil”, and “regular”—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 Mayonnaise 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 Mayonnaise 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

Mayonnaise, fat free is higher in dietary fiber per 100 g

Mayonnaise, fat free reports 2 g versus 0 g for Mayonnaise, light: a 2 g difference when both are normalized to 100 g.

Inspect the underlying evidence

The denominator changes the answer

Mayonnaise, reduced fat, with olive oil is denser; Mayonnaise, fat free is higher in its source amount

Mayonnaise, reduced fat, with olive oil reports 800 mg per 100 g and 72 mg in USDA source amount (9 g). Mayonnaise, fat free reports a lower 750 mg per 100 g but a higher 83 mg in USDA source amount (11 g).

Choose the record before reading the number

Mayonnaise, fat free and Mayonnaise, light are not interchangeable

The page keeps both records at the same 100 g denominator and makes Fat-level wording (nonfat or fat-free wording 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.
