Mozzarella's Potassium Content Explained
Yes, mozzarella cheese does contain potassium, but in very small amounts, especially when compared to the potassium content of milk. This low level is a direct result of how cheese is made. During the production process, milk is separated into curds (solids) and whey (liquid). Most of the potassium, being a water-soluble mineral, remains in the whey, which is then drained off. The final solid cheese product is therefore left with a significantly lower concentration of the mineral.
Potassium in Different Types of Mozzarella
The potassium content can differ slightly depending on the specific type and processing of the mozzarella. For example, a standard 1-ounce serving of whole milk mozzarella contains roughly 22 mg of potassium. Part-skim, low-moisture mozzarella also contains a comparably low amount, around 27 mg per ounce. However, those on a severely restricted potassium diet should be aware of low-sodium cheese varieties. Some producers replace sodium chloride (salt) with potassium chloride to maintain flavor, which can result in a higher potassium count. Always check the ingredient list for 'potassium chloride' if you need to strictly limit your intake.
How Mozzarella Compares to Other Cheeses
When looking at the broader spectrum of cheeses, mozzarella consistently falls into the low-potassium category. For instance, according to the National Kidney Foundation, mozzarella contains approximately 22 mg of potassium per ounce, which is similar to Swiss cheese (31 mg/oz) and Monterey Jack (25 mg/oz), but much lower than ricotta cheese (136 mg per 1/4 cup) or certain high-potassium varieties like Gjetost. Soft goat cheese is one of the lowest at around 7 mg per ounce. This makes mozzarella a safe and accessible option for many people managing their mineral intake, provided they are mindful of portion sizes.
| Cheese Type | Serving Size | Approximate Potassium (mg) |
|---|---|---|
| Mozzarella (Whole Milk) | 1 oz (28 g) | 22 |
| Mozzarella (Part Skim) | 1 oz (28 g) | 27 |
| Swiss Cheese | 1 oz (28 g) | 31 |
| Feta | 1 oz (28 g) | 19 |
| Soft Goat Cheese | 1 oz (28 g) | 7 |
| Ricotta | 1/4 cup | 136 |
Mozzarella in a Kidney-Friendly Diet
Because of its naturally low potassium content, mozzarella can often be incorporated into a diet for people with kidney disease, who are often required to limit their potassium intake. A balanced approach is key, and healthcare professionals generally advise monitoring portion sizes and overall dietary intake. The protein and sodium content in mozzarella also need to be managed, as dairy products can be high in both. Choosing lower-sodium versions can help, but as mentioned, always check for potassium-based salt substitutes. Working with a renal dietitian is the best approach for individuals with specific health needs to determine the appropriate amount of cheese for their diet.
How to Enjoy Mozzarella while Managing Potassium
For those who need to keep potassium levels in check, incorporating mozzarella into meals is simple. Here are some ideas:
- Pizza Topping: Use a measured portion of shredded mozzarella on homemade pizza to control the amount. Combine with low-potassium vegetables like onions and peppers.
- Salad Enhancer: Add small chunks or balls of fresh mozzarella to a salad. A caprese salad with mozzarella, tomato, and basil is a great choice.
- Pasta Dishes: Stir mozzarella into pasta dishes after cooking. This ensures it's properly melted but allows for controlled portioning. Opt for low-potassium sauces.
- Snack Paired with Low-Potassium Foods: Enjoy a small slice of mozzarella with crackers or as part of a cheese board featuring other low-potassium options.

Conclusion
In summary, while mozzarella cheese does have potassium, its content is minimal due to the cheesemaking process. Standard whole milk or part-skim mozzarella is a low-potassium food and can be a suitable option for many dietary plans, including those that require a controlled potassium intake. It is important to check the nutritional information for low-sodium products, as they may contain potassium chloride as a salt alternative. When used in moderation, mozzarella can be a delicious and balanced part of a healthy diet.
