Cheese, Mozzarella, nonfat or fat free calories: 30 per 1 slice (21 g)
This exact USDA record reports 30 calories for 1 slice (21 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 30 calories for 1 slice at 21 grams. On a fixed-weight basis, the same record contains 141 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 6.7 g protein, 0.4 g fiber, and 156 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is cheese, mozzarella, nonfat, representing 100% of the record’s listed input weight. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 slice at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 7–344 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.
Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2705725: “Cheese, Mozzarella, nonfat or fat free.” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.
01 · Portion arithmetic
Three weights, one fixed composition
For FDC 2705725, each row multiplies the published per-100-gram values by its stated weight. “1 string” through “1 cup, melted” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 stringUSDA-listed household measure | 4.7 g | 7 kcal | 1.5 g | 0.1 g | 35 mg |
| 1 sliceUSDA-listed household measure | 21 g | 30 kcal | 6.7 g | 0.4 g | 156 mg |
| 1 cup, meltedUSDA-listed household measure | 244 g | 344 kcal | 77.3 g | 4.4 g | 1,813 mg |
02 · Fixed-weight context
Where 100 grams sits inside Cheese
The comparison set contains 41 exact records in the Cheese USDA category. Here, “lower quarter” describes FDC 2705725’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2705725’s 21 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Calcium; the larger tradeoff-side percentage is Sodium. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.
Strength-side signals
Calcium202 mg
≈ 16% DV. This does not cross the FDA’s 20% ‘high’ guide.
Tradeoff-side signals
Sodium156 mg
≈ 7% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Cheese, Mozzarella, nonfat or fat free,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2705711 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 string to 1 cup, melted
USDA assigns those measures 4.7 g and 244 g. At this record’s fixed composition, scaled energy moves from 7 kcal to 344 kcal.
- 02
Record choice: compare with FDC 2705711
At an equal 100 g, this record has 1.8 g more dietary fiber than “Cheese, Cheddar, nonfat or fat free.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Cheese, mozzarella, nonfat
USDA derives this record from one listed source-input row at 100 g. Real preparations can still differ in water, cooking state, brand, and served weight.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “Mozzarella; nonfat or fat free” fits. Inspect FDC 2705711 when “Cheddar; nonfat or fat free” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2705725 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Cheese, Mozzarella, nonfat or fat free” inspectable beside similarly named records.
How to read this
A single-source formulation
Cheese, mozzarella, nonfat is the only listed source input for this record. That does not mean every real-world version is identical; brands, preparation, water content, and portion weight can still differ.

Exact-record context
What makes this USDA record distinct?
For FDC 2705725, the close-record rule searches the USDA “Cheese” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

Plain-English read
At the fixed 100-gram basis, this record lists 16 less calories, 3.6 g less carbohydrate, and 1.8 g more dietary fiber than “Cheese, Cheddar, nonfat or fat free.”
Only this record lists Cheese, mozzarella, nonfat. Only the comparison record lists Cheese, cheddar, nonfat or fat free. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
4 of the six displayed differences clear the documented materiality screen. It is a reading aid, not a health rating.
Formulation evidence
The listed formulations differ
The formulation rows differ, but the source data do not isolate which component caused any nutrient difference. Input weights describe the standardized formulation—not final plated proportions.

Uncertainty, made actionable
What can change this estimate?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with portion size, fat level, brand or formulation, added flavors or sweeteners.
For “Cheese, Mozzarella, nonfat or fat free,” resolve portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
portion size
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
- 02
fat level
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
- 03
brand or formulation
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 04
added flavors or sweeteners
Use a label or known recipe when available, because sweetness does not reveal dose. Keep syrups, sugars, and concentrated add-ins separate when the base record does not name them.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2705725 comes from FoodData Central Survey Foods (FNDDS). Its 141 kcal per 100 g becomes 30 kcal at 21 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.
About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 slice has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2705725
FNDDS food code: 14107060
The scaling for FDC 2705725 can be exact while the match to “Cheese, Mozzarella, nonfat or fat free” is wrong. That is why this profile keeps its 21 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
