Cheese String Calories: Regular vs Light Compared

How Many Calories Are in a Cheese String?

A regular string cheese has about 80 calories. The light version runs around 50 calories, and a true nonfat mozzarella string cheese drops all the way to about 42 calories while still packing 9 grams of protein. Whole milk versions run a bit higher, close to 90 calories per stick.

Below, we compare every fat level the major brands sell, show the full nutrition label, and check how string cheese really stacks up against Babybel.

Cheese String Calories By Type

The nonfat version is the real standout most articles miss. It has the highest protein of any type here, at 9 grams, while running the lowest calories by a wide margin. If protein-per-calorie is your goal, nonfat mozzarella string cheese, not the “light” version, is the actual best pick.

Full Nutrition Facts: Named Brands Compared

Different brands land in slightly different places even within the “regular” category. Here is what several major brands report on their own labels.

The spread between brands is small, generally 10 calories and 40mg of sodium, so switching brands will not meaningfully change your daily total either way. You can look up any specific brand’s full nutrient panel yourself at the USDA FoodData Central database.

Why “Part-Skim” Doesn’t Mean Fat-Free

Most string cheese, including many labeled as light, is made from part-skim mozzarella rather than whole milk mozzarella. Part-skim simply means some of the milk fat was removed before the cheese was made, not that it is fat-free.

A regular part-skim string cheese still carries 5-6 grams of fat per stick. Light versions cut that to around 2.5-3 grams, and true nonfat versions cut it to under 1 gram, which is where the biggest calorie savings comes from.

String Cheese as a Protein Snack

Ounce for ounce, string cheese offers one of the better protein-to-calorie ratios among common snacks. A regular stick provides 7 grams of protein for around 80 calories, and the nonfat version actually beats it on pure protein density, delivering 9 grams for just 42 calories.

This is part of why string cheese remains a popular choice for kids’ lunchboxes and adult snack routines alike, since it delivers real protein in a low-effort, no-prep format. For more on daily protein targets, see our protein per day guide.

Eating Two String Cheeses at Once

Since one stick is fairly low calorie, many people default to eating two without much thought, especially as an afternoon snack. Two regular sticks land around 160 calories with about 14 grams of protein, which is still a reasonable snack for most calorie budgets.

The main thing worth tracking is sodium, since string cheese runs 150-220mg of sodium per stick depending on brand. Two sticks in one sitting can add up to a meaningful portion of a daily sodium target, especially if paired with other salty snacks later in the day.

Ingredients and Allergens

String cheese is made from pasteurized part-skim (or whole) milk, salt, cheese cultures, and enzymes, sometimes with a small amount of vinegar added during processing. Every string cheese on the market contains milk, so it is not an option for anyone with a dairy allergy or a strict vegan diet, even though the ingredient list itself is short and simple. Most major brands, including Kraft, Polly-O, and Frigo, label their string cheese as gluten-free.

String cheese is naturally low in carbs, typically under 1 gram per stick, which makes it a common choice on keto and other low-carb eating plans.

String Cheese vs Babybel: The Real Numbers

Babybel runs slightly lower in calories, but string cheese actually wins on protein, delivering nearly twice as much per stick. If the goal is protein density rather than the lowest possible calorie count, string cheese is the better pick of the two, not just a similar alternative.

How String Cheese Fits Your Daily Calories

At 42-90 calories per stick depending on type, string cheese is one of the easier snacks to fit into almost any calorie target. If you are tracking toward a specific number, check your TDEE Calculator first, then use the calculator above to see how one or two sticks fits your day. Our guide to how many calories you should eat per day can help set that target.

String Cheese for Kids vs Adults

String cheese is a staple in school lunchboxes partly because of its built-in portion control and no-mess format. For kids, one stick provides a meaningful protein boost without the sugar spike of most other packaged snacks.

For adults managing weight or macros, string cheese works well as a between-meal snack that curbs hunger without a large calorie cost. Pairing it with a piece of fruit rounds out the snack with some fiber and natural sugar, balancing the protein-heavy cheese.

Reading String Cheese Labels Correctly

Not all “light” or “reduced fat” labels mean the same calorie count across brands, and the two terms are not interchangeable. Based on standard label data, “light” versions typically run around 50 calories, while “reduced fat” versions marketed separately can sit closer to 70 calories, since they remove less fat than a true light product. A separate nonfat line exists too, running even lower than either. Checking the actual calorie number on the label, rather than relying on marketing terms alone, gives a more accurate picture when comparing brands side by side.

Common Mistakes That Add Hidden Calories

• Assuming “part-skim” means fat-free, when regular part-skim string cheese still carries meaningful fat
• Confusing “light” and “reduced fat” labels, which are not the same calorie count
• Not knowing a nonfat mozzarella version exists with more protein and fewer calories than “light”
• Ignoring sodium content while eating multiple sticks in one sitting
• Pairing string cheese with high-calorie crackers or bread without accounting for the combined total
