Nutrition per 100 grams
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
The material primary-nutrient differences run in both directions: A is higher on 2, while B is higher on 1.
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.

What differs in the source descriptions
The exact names carry information the numbers cannot.
USDA assigns both records to “Pretzels/snack mix,” but the topic label is broad. Record A is “Pretzels, hard, flavored, gluten free.” Record B is “Pretzels, hard, plain, lightly salted.” 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 2 interpretable distinctions. These labels organize wording already present in the names; they do not establish that a distinction caused a nutrient difference.
| Description dimension | Record A | Record B |
|---|---|---|
| Sodium wording | No matching controlled term in the source name | salted |
| Gluten wording | gluten-free wording | No matching controlled term in the source name |
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 28 g. Record B uses USDA reference amount at 28 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 medium single serving bag: 57 g in A vs 57 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 medium single serving bag.

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 Snacks, Pretzels, gluten- free made with cornstarch and potato flour, Vegetable oil, NFS, Salt, table. Record B’s include Snacks, pretzels, hard, plain, made with enriched flour, unsalted, Snacks, pretzels, hard, plain, salted. Ingredient-code overlap is 0%, and normalized listed-input-weight variation is 100%.

0 shared coded inputs
The two listed formulations do not share an ingredient code in this source extract. Shared codes can still carry different listed weights.
3 A-only and 2 B-only coded inputs
A-only entries include Snacks, Pretzels, gluten- free made with cornstarch and potato flour, Vegetable oil, NFS, Salt, table. B-only entries include Snacks, pretzels, hard, plain, made with enriched flour, unsalted, Snacks, pretzels, hard, plain, salted.
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.
- NFS means “not further specified.” The record intentionally leaves the exact subtype, size, or preparation unresolved.
- NS as to… means “not specified as to…” the detail that follows. It preserves an unknown distinction; it does not mean the ingredient or characteristic is absent.
Choosing the closer record
Match context first; scale second.
- 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.
- 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.
- 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.
- 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 2 documented description dimensions, while the listed formulations show 0% ingredient-code overlap and 100% 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.
