Pick the mozzarella type, then choose the form you measured. A cup of shredded cheese, a cup of melted cheese, and one stick do not weigh the same.
A worked portion example
Illustrative calculation: 1 stick weighs 28.4 g using the linked record's portion weight. At 296 calories per 100 g, 28.4 × 296 ÷ 100 = about 84 calories and 6.7 g protein. The published stick is 28.4 g. Use the weight on your wrapper if it differs.
Check the exact food and household measure →The part-skim example lists a shredded cup as 113 g, a diced cup as 132 g, and a melted cup as 244 g. Select the form you measured, or use grams if you packed the cup differently. A cup is not a single weight across all forms of cheese.
The selected part-skim example uses low-moisture mozzarella. The nonfat and reduced-sodium options are different entries. A fresh mozzarella ball or a particular string-cheese brand may be better represented by its package label than by this limited set of examples.
Weigh the cheese added to the whole dish, then assign the share in the portion you ate. If you already use a complete pizza or lasagna entry, it includes a recipe's cheese; add only extras you have reason to count beyond that preparation.
Editorial update: . Portion examples are calculations from the linked USDA records.
The 3 exact records in this guide report 30–62 calories in the records' own listed source servings and 141–296 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.
Across all 3 named USDA examples, a cup, melted contains 344–722 calories. Each included example lists 244 g for that measure. The same household label can carry a different gram weight elsewhere in USDA data.
Match my meal
For Mozzarella, begin by separating “Cheese, Mozzarella, nonfat or fat free” from “Cheese, Mozzarella, reduced sodium.” 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
This guide keeps 3 named USDA records in view: 3 direct matches. All sit within “Cheese.” 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 3 records together under the exact grouping key “cheese mozzarella.” That rule determines membership before any nutrition result is read.
For Mozzarella, this page can compare 3 named records from FDC 2705725 through FDC 2705724. It cannot observe which preparation was eaten, recover unnamed additions, or supply the eaten grams.

Editor’s decision brief
Carry the denominator, exact identity, and strongest observed contrast into every number below.
Portion
Equal source weights make the selected Mozzarella serving totals easier to compare, but the eaten portion still has to be measured or estimated.
Composition
The lower endpoint is “nonfat or fat free”; the higher is “part skim.” This isolates density, not ingredient causation.
Discriminator
Of protein, fiber, and sodium, the strongest normalized contrast is between “reduced sodium” (16 mg) and “nonfat or fat free” (743 mg).
Observed source examples
These 3 records each use a 21 g serving. Their serving calories compare equal weights within this set. They do not define a calorie range for every mozzarella; match the preparation and adjust to your portion.

Full comparison
For Mozzarella, 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.

Portion analysis
Every selected record uses a 21-gram source amount, so serving-weight differences do not explain the calorie spread inside this set. Their own source servings run from 30 calories for “nonfat or fat free” to 62 for “part skim.” At a fixed 100 grams, “nonfat or fat free” is 141 calories and “part skim” is 296—a fixed-weight separation of 155 calories. For Mozzarella, 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 published descriptions distinguish forms such as “Mozzarella, nonfat or fat free”, “Mozzarella, part skim”, and “Mozzarella, reduced sodium”. The source formulations contain 3 distinct ingredient codes; examples that appear in only part of the set include cheese, mozzarella, low moisture, part-skim, cheese, mozzarella, low sodium, and cheese, mozzarella, nonfat. On this Mozzarella 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
The family label “Mozzarella” cannot resolve the differences between Cheese, Mozzarella, nonfat or fat free and Cheese, Mozzarella, reduced sodium. The four checks below identify the record wording, source weight, and formulation evidence that can.
Every selected record uses 21 grams. Inside this set, serving-calorie differences therefore reflect the published composition rather than a change in source weight.
Representative record-level distinctions include “Mozzarella, nonfat or fat free”, “Mozzarella, part skim”, and “Mozzarella, reduced sodium”. Those phrases are evidence for choosing a record, not decorative subtitle text.
3 source-input codes appear across the selected records. Their presence and listed weights describe USDA formulations, not finished plated proportions.
Even “Cheese, Mozzarella, nonfat or fat free” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Mozzarella unknowns for correction instead of converting them into false precision.
Record matching
Read the source name as a sequence of decisions. First confirm that mozzarella is the right meal family. Then resolve the phrases that actually separate this set—“Mozzarella, nonfat or fat free”, “Mozzarella, part skim”, and “Mozzarella, reduced sodium”—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.
Decision support from the exact records on this page
These conclusions and reading paths are computed from 3 exact records behind Mozzarella 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
Cheese, Mozzarella, nonfat or fat free reports 1.8 g versus 0 g for Cheese, Mozzarella, part skim: a 1.8 g difference when both are normalized to 100 g.
Inspect the underlying evidenceThese listed servings have equal weights
The 3 records with a listed serving weight on this page each use 21 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
The page keeps both records at the same 100 g denominator and makes Sodium wording (No matching controlled term in the source name versus reduced- or low-sodium wording) 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.
Inspect the underlying evidenceContextual knowledge graph
For Mozzarella source-record guide, each path states why the destination belongs here, so you can distinguish a true evidentiary connection from a merely similar label.
Both records appear in this page’s evidence set. The explicit record-description contrast is Sodium wording: No matching controlled term in the source name versus reduced- or low-sodium wording; it is a selection cue, not evidence of cause.
