Best High-Protein Cheese (Snacks & Slices)

Cheese is one of the densest protein foods on the grocery shelf — most real cheese matches cooked meat gram-for-gram. But it is also the lowest-scoring category on Labelgrade, and we want to be straight about why. Below: every branded cheese in our database, ranked by the six-dimension Labelgrade v3 score, with the trade-offs spelled out. For everything else, see the full /explore page.

The short answer

Cheese is structurally a mid-grade category, and there is no way around it. Two of our six scoring dimensions — saturated fat and sodium — are inherently bad for cheese. Concentrating milk into cheese concentrates the milkfat (most aged cheese runs near or over the FDA's 20 g daily saturated-fat ceiling at just 100 g), and salt is non-negotiable in the curd-forming and aging process. So even the cleanest, most premium cheese lands in the C range — the live average across this list is about 64 / 100. That is not a knock on any one brand; it is the category telling you what cheese is. Our State of Packaged Protein report found cheese the single lowest-scoring category on the entire site.

So this roundup is not about finding a cheese that scores like Greek yogurt — none does. It is about the best protein-per-trade-off: the most protein for the least saturated-fat-and-sodium baggage, with a clean label and a portion that is hard to overdo. On that measure the live pick is Frigo Frigo, Cheese Heads, Light String Mozzarella Cheese — part-skim mozzarella that hits the same protein density as cheddar at roughly half the saturated fat, pre-portioned into single sticks. Read the grades below as a portion-control signal, not a verdict on quality.

The ranked list

Ranked by Labelgrade v3 overall score, then by protein per serving. Every figure is pulled live from our database and verified against USDA FoodData Central — nothing here is hand-typed, so it cannot drift out of sync with the fact sheets.

String cheese and Babybel: the portion-controlled protein snacks

If you are buying cheese specifically for protein, this is the tier that earns it. A stick of Kraft Mozzarella String Cheese or Sargento String Cheese delivers about 6 g of protein at 60–70 calories, with a clean four-to-five-ingredient label and zero sugar. Per 100 g, string cheese hits ~25 g of protein — denser than any plain Greek yogurt — and because it is made from part-skim mozzarella, its saturated fat is roughly half that of a cheddar block. Babybel Original sits right alongside it: a 3-ingredient Dutch-style wheel with 5 g of protein at 70 calories and essentially the same protein density.

The real advantage here is not the macros — it is the portion. A single wrapped stick or wax wheel is a fixed, modest serving, which is what keeps the sodium (around 160–180 mg per piece) and saturated fat reasonable. Eat one or two as a snack and the structural downsides of cheese stay small. That pre-portioning is exactly why these products grade better than the cheddar blocks below them, despite identical protein density: a block invites a bigger, harder-to-measure portion.

Why aged and block cheese scores lower

Aged cheddars and jack cheeses cluster tightly: Cabot Sharp Cheddar, Tillamook Extra Sharp, Kraft Natural Pepper Jack, and Cabot Pepper Jack all deliver about 7 g of protein per ounce (~25 g per 100 g) on genuinely clean four-to-five-ingredient labels. Their protein density scores an A‑. So why do they land a point or two below string cheese?

Saturated fat. A full-fat aged cheese carries roughly 6 g of saturated fat per ounce — about 21 g per 100 g, which exceeds the FDA's entire 20 g daily ceiling in just 100 g of cheese. That is not a Cabot problem or a Tillamook problem; it is a cheddar problem. No aged cheese — organic, grass-fed, extra-aged, farmer-cooperative, or boutique — escapes it, because the fat is the cheese. The takeaway is not "avoid these," it is "treat them like what they are": a flavor-dense protein-and-calcium accent on eggs, a salad, or a burger, not the thing you lean on for daily protein volume. Two ounces gets you ~14 g of protein and qualifies as "high in protein," but it also spends most of your day's saturated-fat budget.

Sodium in processed slices and spreads

The bottom of the list separates into two different stories. The first is the soft, cream-based cheeses — Philadelphia Cream Cheese and Boursin Garlic & Herb — which carry only about 2 g of protein per serving against 4.5–6 g of saturated fat. The cream that makes them spreadable also dilutes the protein. They have clean labels, but they are fat-and-flavor foods, not protein foods; judge them as spreads.

The second story is process cheese. Kraft Singles are legally a "pasteurized prepared cheese product," not natural cheese — cheddar rebuilt with added milk solids, whey, emulsifying phosphate salts, and starch so it melts smoothly. A slice carries only about 3 g of protein, roughly half a same-size piece of real cheese, and its sodium (around 200 mg per slice on the package, climbing fast across a multi-slice sandwich) comes partly from those emulsifying salts. It can post a deceptively decent overall grade because there is so little saturated fat per its small serving to penalize — but that is faint praise. If you want the smooth, uniform melt of American cheese on a burger, Singles do a job real cheese cannot quite match. For protein, a slice of real cheddar delivers about double.

How we picked these

This list is generated live from our product database: every item graded in the Cheese category, ranked by the Labelgrade v3 overall score and then by protein per serving. We do not pre-curate it — process cheeses and cream cheeses sit in the same ranking as the string cheese and cheddar, because the honest comparison is the point. A high overall score on a low-protein process slice means the methodology found little to penalize on a small serving, not that it is a strong protein choice; the table's protein column keeps that visible.

Every nutrition figure comes from USDA FoodData Central and is pulled from the same data that powers each product's fact sheet, so the numbers here cannot drift. For the full scoring formula and dimension weights, see our methodology.
