The Carbs in Cheese: A Natural Process
At its core, cheese is a low-carb food. This is because the primary carbohydrate in milk is lactose, a type of milk sugar. During the cheesemaking process, enzymes and bacterial cultures are added to the milk to ferment the lactose. This fermentation process converts most of the lactose into lactic acid, which is essential for curdling the milk and developing the cheese's flavor and texture. As a result, the finished cheese product has a significantly lower lactose content than the milk it was made from, which is why most natural cheeses, including mozzarella, are inherently low in carbs. For instance, a 1-ounce serving of whole-milk mozzarella contains only about 0.62 grams of carbohydrates.
The Truth About Anti-Caking Agents
While cheese naturally contains very few carbs, a small variable is introduced when the cheese is sold pre-shredded. To prevent the cheese from clumping together in the bag, manufacturers add anti-caking agents. Common anti-caking agents include powdered cellulose, potato starch, or corn starch. These powdery starches act as a coating for the cheese shreds. While effective at keeping the cheese from sticking, these additives are a source of carbohydrates. A bag of pre-shredded mozzarella will reflect this on its nutrition label, showing a slightly higher carb count than block mozzarella.
How Additives Impact the Carb Count
- Small, but not insignificant: For someone on a ketogenic diet that requires an extremely low daily carb intake, the small amount of carbs from anti-caking agents can add up, especially if using a larger quantity of cheese.
- Ingredient label reveals all: The specific amount of carbohydrates from these starches depends on the brand and the quantity used. You can determine the exact impact by checking the ingredient list on the package.
Comparison: Pre-Shredded vs. Block Mozzarella
To truly understand the difference, a comparison is helpful for those conscious of their carbohydrate intake.
| Attribute | Pre-Shredded Mozzarella | Block Mozzarella |
|---|---|---|
| Carbohydrates | Contains trace carbs from anti-caking starches (e.g., 1-2g per serving). | Virtually no carbs, consisting of only natural lactose trace amounts. |
| Ingredients | Cheese plus anti-caking agents like cellulose or potato starch. | Simply cheese, with no additives. |
| Melt Quality | Melts less smoothly and can be gritty due to the starch coating. | Melts perfectly and consistently for a classic, gooey stretch. |
| Cost | Often slightly more expensive per pound due to the added processing. | Usually more cost-effective per pound. |
| Convenience | Highly convenient for quick use. | Requires an extra step of manual shredding. |
Making the Right Choice for Your Diet
For most people following a general low-carb diet, the minimal carbs from pre-shredded mozzarella are not a concern. However, if you are pursuing a strict ketogenic diet where every gram of carbohydrate counts, opting for block mozzarella and shredding it yourself is the safest bet. The shredding process only takes a few minutes and ensures a purer product with better melt quality. If convenience is your top priority and your carb limit is not extremely tight, pre-shredded is still a perfectly viable option.
Reading the Nutrition Label
For informed decisions, always check the nutrition label. The label will list the total carbohydrates per serving, and the ingredients list will show if anti-caking agents have been used. A good practice is to look for brands that advertise as containing no anti-caking agents if you want to use the pre-shredded convenience while minimizing carb intake.
Incorporating Low-Carb Mozzarella into Your Meals
- Keto Pizza: Create a fathead dough or a cauliflower-based crust and top it with plenty of shredded mozzarella for a classic low-carb pizza.
- Stuffed Chicken Breast: Stuff chicken breasts with a mix of mozzarella, herbs, and other low-carb fillings like spinach or pepperoni.
- Cheese Crisps: Bake small piles of shredded mozzarella on a parchment-lined baking sheet until crispy for a crunchy, low-carb snack.
- Salad Topping: Sprinkle a generous amount of shredded mozzarella over a fresh garden salad for extra protein and flavor.
- Lasagna Substitute: Use shredded mozzarella in a low-carb lasagna, replacing traditional pasta with layers of zucchini, eggplant, or shredded chicken.
The Nutritional Punch of Mozzarella
Beyond its low-carb profile, mozzarella offers a range of health benefits. It is an excellent source of calcium and phosphorus, vital for bone and dental health. As a dairy product, it provides high-quality protein, which is essential for muscle maintenance and repair. Mozzarella also contains probiotics in some forms, which promote good gut health. These nutrients make it a valuable and versatile component of a healthy diet, regardless of your carb restrictions.

Conclusion
In summary, while natural mozzarella cheese is virtually carb-free, commercially pre-shredded versions contain a small number of carbohydrates due to the addition of anti-caking agents. For most people, this minimal amount is insignificant and does not affect low-carb goals. However, for those on strict keto or zero-carb diets, opting for block mozzarella and shredding it at home is the best approach to avoid any added carbs and achieve a superior melt. Ultimately, both options are low-carb and offer a wealth of nutrients, allowing you to enjoy your favorite cheesy dishes while staying mindful of your intake.
