Both columns use the same mass, which compares nutrient concentration without allowing the two representative source amounts to change the denominator. “A +” or “B +” reports the arithmetic difference between the cited values; it is not a quality score.

Read the table by question

Every material primary-nutrient difference on this page is numerically higher in A (2 of 2).

These answers describe concentration per 100 grams. “More” and “less” identify the arithmetic direction only; they do not decide which record is a better match or which food is better for a person.

Which reports fewer calories?

Record B

Record B reports 52 kcal, compared with 100 kcal in the other record—a difference of 48 kcal.

Which reports more protein?

Record B

Record B reports 10.7 g, compared with 10 g in the other record—a difference of 0.7 g.

Which reports more fiber?

Same reported value

Both records report 0 g of fiber per 100 g.

Which reports less sodium?

Record B

Record B reports 281 mg, compared with 282 mg in the other record—a difference of 1 mg.

What differs in the source descriptions

The exact names carry information the numbers cannot.

USDA assigns both records to “Eggs and omelets,” but the topic label is broad. Record A is “Egg, white, cooked, fat added.” Record B is “Egg, white, cooked, no added fat.” Feast paired them because their contrast-neutral food identities are an exact match, not merely because they share a generic category.

The controlled name parser found 1 interpretable distinction. These labels organize wording already present in the names; they do not establish that a distinction caused a nutrient difference.

Controlled wording distinctions
Description dimensionRecord ARecord B
Added-fat wordingadded fatno added fat

Even a clean name contrast can carry hidden companions. A fried record may also include coating; a restaurant record can use a different recipe; a reduced-sodium description can differ in more than salt; and a source amount can reflect a different reporting convention. That is why this page reports the complete pair rather than treating one word as an intervention.

Portion context

A representative source amount is not a shared “serving.”

Record A uses USDA reference amount at 36 g. Record B uses USDA reference amount at 33 g. Those labels and gram weights come from their respective records. They are useful for scaling the chosen profile, but they are not recommendations and need not describe equal amounts.

The representative amounts do not cross Feast’s material portion-difference threshold of both 15 grams and 20%. They are still separate source measures, so the 100-gram table remains the appropriate place for an equal-weight comparison.

A cup, piece, slice, sandwich, fillet, or fluid ounce can have different gram weights across records. A matching label is not enough: check the listed grams. If accuracy matters more than convenience, weighing the food or using a current package label can be more specific than a generic survey-food measure.

One shared household label

1 cup: 135 g in A vs 135 g in B

Here the household label and listed gram weight match at displayed precision, so this particular table is also an equal-mass comparison. The values remain specific to these two source records, not a universal weight for every 1 cup.

USDA source formulation evidence

The listed inputs provide another way to audit the match.

FNDDS includes input-food rows behind each standardized survey-food record. Record A’s leading listed inputs include Eggs, Grade A, Large, egg white, Oil or table fat, NFS, Salt, table. Record B’s include Eggs, Grade A, Large, egg white, Salt, table. Ingredient-code overlap is 67%, and normalized listed-input-weight variation is 7%.

2 shared coded inputs

The largest shared entries include Eggs, Grade A, Large, egg white, Salt, table. Shared codes can still carry different listed weights.

1 A-only and 0 B-only coded inputs

A-only entries include Oil or table fat, NFS.

Important: repeated rows carrying the same ingredient code are combined before the shares and overlap are calculated. These weights belong to USDA’s source formulation: they are not a reconstructed plate, final cooked yield, visitor serving, ingredient declaration, or estimate of what is visible in a photo. USDA’s FNDDS documentation explains that these calculation recipes can represent multiple variants, may include retention or moisture adjustments, and are not product-label ingredient lists.

USDA shorthand in this evidence
  • NFS means “not further specified.” The record intentionally leaves the exact subtype, size, or preparation unresolved.

Choosing the closer record

Match context first; scale second.

  1. 01

    Read both names literally

    Compare cooking method, coating, edible skin or peel, sauce, additions, venue, source form, and food subtype. For this pair, the full A and B descriptions above are the evidence—not shortened search labels.

  2. 02

    Use listed inputs as a check

    If the name still leaves ambiguity, compare the leading and unique source inputs. They can reveal that two near names refer to meaningfully different standardized formulations, but they do not reconstruct your dish.

  3. 03

    Choose an amount for that record

    After choosing A or B, use its own named measure and gram weight. Do not transfer a cup, slice, or “typical amount” from the other record as if the measures were interchangeable.

  4. 04

    Account for missing details

    Brand, current restaurant recipe, cooking oil, drained weight, toppings, substitutions, and unfinished portions may not be captured. A label or weighed recipe can supersede a generic reference when it better matches the actual food.

Limits and responsible interpretation

This is a comparison of records, not a causal study.

The two records come from 2021–2023 FoodData Central Survey Foods data. The nutrient table faithfully compares their published values on the same weight basis. It does not measure two plates prepared at the same time, isolate one ingredient, or estimate the uncertainty around either value.

For this pair, the source names differ across 1 documented description dimension, while the listed formulations show 67% ingredient-code overlap and 7% normalized listed-weight variation. Moisture, ingredient proportions, preparation, and record construction can therefore move together. The page can describe the combined record difference; it cannot isolate the effect of one word.

A higher or lower number is not an overall verdict. Protein, fiber, sodium, energy, fat, micronutrients, preferences, allergies, budget, portion, and an individual’s goals answer different questions. Feast therefore reports directions and magnitudes without applying a universal “healthier” label.

This page is educational and does not diagnose a condition, prescribe a target, or replace advice from a qualified professional. For an allergy, medically directed diet, or strict ingredient limit, use verified ingredient information and guidance appropriate to that situation.

How this page qualified

A page is published only when the pair clears materiality and diversity gates.

Both records must occupy the same USDA survey-food topic and share a close food identity after a controlled vocabulary separates preparation, edible-part, source, claim, crust, and sauce wording. Exact contrast-neutral identities receive priority. Close ingredient or form substitutions can qualify when name overlap remains high and the numerical evidence is material.

For primary nutrients, Feast requires both an absolute and relative difference: at least 20 kcal and 12% for energy; 2 g and 18% for protein or fat; 5 g and 15% for carbohydrate; 1 g and 20% for fiber; 4 g and 20% for sugars; or 100 mg and 20% for sodium. A focused one-nutrient pair also needs a material representative-amount or formulation distinction. Rounding-only pairs are not published.

Unordered FDC IDs define a canonical pair, so reversing A and B cannot create another page. Each source record can appear twice at most, each USDA topic contributes no more than 40 pages, and closely repeated identity families are capped. Those rules produced a selective comparison library rather than every mathematical combination in the corpus.
