For many people watching their sugar intake, mozzarella seems like a tempting but risky choice due to its dairy origins. However, the truth is that this beloved cheese is surprisingly low in sugar. The answer to the question, "Is there a lot of sugar in mozzarella cheese?" is a resounding no. Its minimal sugar content is a direct result of the complex process of cheesemaking, which transforms milk's natural sugars into a nutritious, low-sugar food.
The Science Behind Low-Sugar Mozzarella
Lactose Fermentation in Cheesemaking
All cheese begins as milk, which naturally contains a sugar called lactose. During the initial stages of cheesemaking, starter cultures—beneficial bacteria—are added to the milk. These cultures begin a process of fermentation, consuming the lactose and converting it into lactic acid. This process is what gives cheese its characteristic tang and helps it to set.
For most cheeses, including mozzarella, this fermentation process continues until the lactose is largely depleted. The final product, whether fresh or shredded, contains only trace amounts of the original milk sugar. Aged cheeses have even less lactose, but even fresh mozzarella, which is not aged for long, has significantly less lactose than a glass of milk.
The Pasta Filata Method
Mozzarella's unique production, known as the pasta filata (spun paste) method, further contributes to its low sugar content.
- Whey Draining: After fermentation, the solid curd is separated from the liquid whey. Whey contains a significant amount of the milk's remaining lactose, so draining it removes a large portion of the sugar.
- Stretching and Kneading: The curd is then heated and stretched. This process further expels moisture and any residual lactose, leaving behind a cheese with a low carbohydrate and sugar profile.
Comparing Mozzarella: Types and Sugar Content
While all mozzarella is low in sugar, a few minor variations can be noted based on its form and fat content. However, these differences are minimal and don't significantly impact the overall low-sugar profile.
- Fresh vs. Shredded Mozzarella: Fresh mozzarella may contain slightly more lactose than shredded varieties, as some is lost during the shredding and anti-caking treatment. However, the difference is negligible for a typical serving. Shredded versions sometimes have small amounts of starch-based anti-caking agents, but these have a minor effect on total carbohydrate and sugar numbers.
- Whole Milk vs. Part-Skim: The sugar content is primarily affected by the removal of lactose, not fat. Both whole milk and part-skim mozzarella remain very low in sugar, with part-skim offering a lower-fat alternative.
Comparison Table: Mozzarella vs. Other Cheeses
To put mozzarella's low sugar content into perspective, here is a comparison of common cheeses per one-ounce serving.
| Cheese Type | Total Sugar (grams) | Notes |
|---|---|---|
| Mozzarella (Part-Skim) | 0.17 | Very low, due to lactose fermentation. |
| American Cheese | 0.6 | A processed cheese with slightly more sugar. |
| Cheddar Cheese | <0.5 | Very low, as it is an aged cheese. |
| Parmesan | 0 | Aged and hard, with virtually no sugar. |
| Swiss Cheese | 0 | Another low-carb, low-sugar option. |
Mozzarella in Your Diet: Beyond Just Low Sugar
Mozzarella offers several nutritional benefits, making it an excellent addition to many diets, including low-carb and ketogenic plans.
- Excellent Source of Protein: It provides a significant amount of high-quality protein, essential for muscle repair and growth.
- Rich in Calcium and Phosphorus: These minerals are vital for strong bones and teeth, helping to reduce the risk of osteoporosis.
- Source of Probiotics: Some fresh, unpasteurized mozzarella varieties contain beneficial bacteria, which can support gut health and digestion.
- Immunity Boosting Vitamins: It contains vitamins like B12 and minerals such as zinc and selenium, which play a key role in supporting the immune system.
Conclusion: The Low-Sugar Verdict on Mozzarella
So, is there a lot of sugar in mozzarella cheese? The evidence is clear: no. The cheesemaking process naturally eliminates almost all of the lactose, resulting in a product with a minimal sugar content. Whether you prefer it fresh or shredded, mozzarella is a reliable low-sugar, low-carb dairy option that can fit into a healthy diet. Beyond its low sugar profile, it offers a wealth of essential nutrients like protein and calcium, making it a smart and satisfying choice for anyone prioritizing a balanced, nutritious diet.

How to Read the Nutrition Label
To be sure of the nutritional content of any specific brand, it is always best to check the nutrition label. Here's what to look for:
- Serving Size: Always note the serving size at the top of the label, as all other nutritional information is based on this amount.
- Total Carbohydrates: Look at the total carbohydrates, which will include any sugar.
- Total Sugars: This will tell you the amount of naturally occurring and added sugars. Many mozzarella labels will show zero or a very small number.
- Added Sugars: If the label lists added sugars, this indicates sugars that were not originally present in the milk. Most plain mozzarella will have zero added sugars.
By following these steps, you can confidently include low-sugar mozzarella in your meals without worrying about hidden sugars.
