Cheese is a popular food, but its nutritional value can vary widely. Diet mozzarella cheese, often made with part-skim milk, offers a different nutritional profile compared to whole milk mozzarella. This article delves into the nutrition facts of diet mozzarella, comparing it to other cheeses and examining its role in a balanced diet.
What is Mozzarella Cheese?
Mozzarella is a white, semi-soft, brined Italian cheese. Traditionally, it's prepared from Italian water buffalo milk, though today the majority is made from cow’s milk unless it specifies ‘mozzarella di bufala’ on the label. Unlike most cheeses, mozzarella is not aged; instead, it is enjoyed fresh immediately after being made. Fresh mozzarella is available in balls of varying sizes, sold in containers filled with water, whey, or brine (like bocconcini).
Production of Cheese
Cheese production begins with the separation of milk into solids (curds) and liquids (whey). This occurs through the acidification of milk via the addition of an acid, such as vinegar, or more commonly with the introduction of a starter bacteria, which converts the sugar in milk (lactose) into lactic acid. Traditionally, this step is followed by the addition of rennet, which is a group of enzymes (primarily chymosin) found in the stomachs of ruminant mammals such as cattle, sheep, and goats. Today, however, most cheese is made with chymosin prepared from bacteria - its function being to curdle the casein in milk. After the curds and whey have been separated, the curds may be further processed. For some cheeses, the curds are cut into smaller pieces to expel liquid - the extent depends on the type of cheese being produced (harder cheeses are drier), while others are heated, stretched, or washed before salting for flavor and preservation. Finally, the cheese is shaped and aged under controlled temperature and humidity anywhere from a few days to several years.
Nutritional Profile of Diet Mozzarella Cheese
Diet mozzarella cheese, typically made from part-skim milk, offers a lower fat content compared to whole milk mozzarella.

Macronutrient Breakdown
The macronutrient breakdown of 1 ounce of part-skim mozzarella cheese is approximately 4% carbs, 57% fat, and 39% protein.
Vitamins and Minerals in Diet Mozzarella
Diet mozzarella cheese provides several essential vitamins and minerals:
- Calcium: Essential for bone health, muscle function, and nerve transmission.
- Vitamin B12 (cobalamin): A water-soluble vitamin that serves as a cofactor for enzymes involved in energy metabolism, red blood cell production, DNA synthesis, neurotransmitter production, nervous system health, and folate metabolism. As a result of these roles, vitamin B12 is vital for maintaining brain and nervous system health, and may have a protective effect against dementia, Alzheimer’s disease, and depression. There’s also some evidence vitamin B12 may be cancer-protective, possibly through supporting folate metabolism (which then assists in repairing DNA damage).
- Phosphorus: Important for bone health, energy production, and DNA synthesis.
- Zinc: Plays a role in immune function, wound healing, and cell growth.
- Selenium: An antioxidant that helps protect cells from damage.
- Riboflavin (B2): Important for energy production and cell function.
Comparing Diet Mozzarella to Whole Milk Mozzarella
While specific nutritional values vary by brand, diet mozzarella generally has:
- Lower Fat Content: Significantly less fat than whole milk mozzarella, particularly saturated fat.
- Fewer Calories: A lower calorie count due to the reduced fat content.
- Similar Protein Content: Often contains a similar amount of protein as whole milk mozzarella.
- Comparable Calcium Levels: The calcium content is usually similar between the two types.
Whole milk mozzarella cheese has a Nutrivore Score of 145, making it a low nutrient-dense food. Diet mozzarella would likely have a similar or slightly lower score due to the reduced fat content.

Health Implications and Considerations
Dairy products, including cheese, can be a part of a healthy diet. Studies suggest that moderate dairy consumption may have some health benefits:
- Cardiovascular Health: A 2021 meta-analysis of 55 prospective cohort studies found that dairy consumption in general was associated with a 10% lower risk of stroke, a 4% lower risk of coronary heart disease, and a 9% reduced risk of hypertension (high blood pressure). A 2016 meta-analysis of 29 cohort studies showed that cheese reduced cardiovascular disease risk, and fermented dairy reduced total mortality risk, albeit by a very modest amount (2% per 20 gram serving of fermented dairy or 10 gram serving of cheese).
- Mortality: A 2017 meta-analysis revealed a U-shaped dose response curve for dairy products, with intake up to about 400 grams daily modestly reducing all-cause mortality (again, only about a 2% effect), but higher consumption levels no longer being beneficial-intake greater than 1000 grams per day was associated with a 15% increased risk of total mortality.
However, it's important to consider:
- Saturated Fat: Saturated fat intake can raise total cholesterol and LDL (low-density lipoprotein) levels, leading to an increased risk of atherosclerosis. Diet mozzarella offers a way to reduce saturated fat intake compared to whole milk versions.
- Sodium Content: Mozzarella cheese can be relatively high in sodium. Individuals monitoring their sodium intake should be mindful of serving sizes.
- Individual Needs: Dietary needs vary. People with lactose intolerance or dairy allergies should avoid mozzarella cheese.
Incorporating Diet Mozzarella into a Balanced Diet
Diet mozzarella cheese can be a versatile ingredient in various dishes:
- Salads: Adds protein and calcium to salads.
- Sandwiches and Wraps: Provides a flavorful and lower-fat cheese option.
- Pizza: Can be used as a topping for homemade pizzas.
- Pasta Dishes: Melts well in pasta dishes.
- Snacks: Enjoyed on its own or paired with fruits and vegetables.
