Can I Eat Cheese if I Have High Potassium?

December 9, 2025 •

4 min read

While many dairy products, including some cheeses, are often limited on a low-potassium diet, a 2017 DaVita article reveals that cheese can often be included safely, with the key being careful research and variety selection. Choosing the right types of cheese in moderation is crucial for those managing high potassium levels, often associated with kidney disease.

Quick Summary

This guide provides an overview of which cheese varieties are safe for those with high potassium, offering nutrient information, portion guidance, and tips for incorporating cheese into a renal diet while managing phosphorus and sodium intake.

Key Points

Low-Potassium Cheeses Exist: Certain cheeses like soft goat cheese, Swiss, and feta are naturally low in potassium and can be enjoyed in moderation.
Portion Control is Critical: Even for safe cheese varieties, managing portion sizes (typically 1 oz) is essential to keep all nutrient levels within recommended limits.
Avoid Processed Cheeses: Processed cheeses and spreads often contain high levels of sodium and phosphate additives, which are harmful for individuals with kidney issues.
Check Labels for Additives: Always read the ingredient list to avoid products with potassium chloride, sometimes used as a salt substitute in low-sodium cheeses.
Factor in Sodium and Phosphorus: When choosing cheese, consider not only potassium but also the sodium and phosphorus content, which can vary significantly by type and brand.
Use Strong Flavors Sparingly: Opt for strongly flavored cheeses like aged cheddar or feta to use smaller, safer amounts for a significant taste impact.
Consult a Renal Dietitian: For personalized dietary advice, especially concerning kidney health, consulting a renal dietitian is the most reliable approach.

Understanding Potassium, Kidney Health, and Cheese

For individuals with high potassium (hyperkalemia), often linked to chronic kidney disease, managing dietary potassium is essential. The kidneys are responsible for balancing potassium levels in the blood, and when their function is impaired, potassium can build up to dangerous levels. While many dairy products like milk and yogurt are known for their moderate to high potassium content, cheese is a more complex category. The potassium levels in cheese vary significantly depending on the type, with some varieties being quite low and suitable for a low-potassium diet. However, it's not just about potassium; those with kidney health concerns also need to consider the phosphorus and sodium content of cheese, which can be high in certain types. Processed cheeses, for instance, are notoriously high in sodium and phosphate additives and are generally best avoided.

Low-Potassium Cheese Options for a Kidney-Friendly Diet

Fortunately, a high-potassium diet does not mean you must completely eliminate cheese. Several varieties are naturally low in potassium, making them excellent choices when consumed in appropriate portion sizes. Soft goat cheese, for example, is highlighted as one of the lowest potassium options. Feta and Swiss cheese are also typically lower in potassium, though their sodium content should be monitored. Cottage cheese can be a good option if a low-sodium version is chosen, as regular varieties are high in sodium. Hard, pungent cheeses like sharp cheddar or blue cheese can be used in small amounts for maximum flavor, allowing for smaller, safer portion sizes.

Factors Beyond Potassium: Sodium and Phosphorus

When selecting a cheese for a high-potassium diet, it's vital to look beyond just the potassium content. Many cheeses, particularly processed types, are also high in phosphorus and sodium, both of which can be problematic for individuals with kidney disease.

Sodium: Excessive sodium can contribute to fluid retention and high blood pressure, putting extra strain on the kidneys. Always check the nutrition label and opt for low-sodium or 'no salt added' varieties where possible, such as Swiss or specific types of cottage cheese. Stronger-flavored cheeses require less to achieve the desired taste, which helps keep sodium intake in check.
Phosphorus: High phosphorus intake can also be a concern. Dairy products are typically high in phosphorus, but some cheeses have lower levels than others. Additives containing phosphate are particularly concerning, so it's wise to avoid processed cheese products. Cottage cheese is generally high in phosphorus, but some low-fat options exist.

Comparison Table: Low vs. High Potassium Cheeses

To make informed choices, here is a comparison of some popular cheese types based on approximate potassium, sodium, and phosphorus levels per 1 oz (28g) serving. Note: Values can vary by brand and preparation.


Cheese Type	Approximate Potassium (mg)	Sodium Level	Phosphorus Concern	Best for High Potassium Diet?
Goat Cheese (Soft)	7	Moderate	Moderate	Yes, in moderation.
Feta	18	High	Moderate	Yes, in small portions.
Swiss	31	Low	Moderate	Yes, good option.
Mozzarella	22	Moderate	Moderate	Yes, a versatile choice.
Cheddar (Low-Sodium)	32	Very Low	Moderate	Yes, but check label.
Cottage Cheese (Regular)	149	High	High	Best avoided due to potassium/sodium.
Processed Cheese Slices	68	Very High	Very High	No, avoid additives.
Ricotta (Part-Skim)	154	Low	High	Use cautiously due to potassium/phosphorus.

Practical Tips for Enjoying Cheese Safely

Incorporating cheese into a high-potassium diet doesn't have to be a guessing game. Here are some actionable tips:

Monitor Portion Sizes: Even low-potassium cheeses should be consumed in moderation. A standard portion is typically 1 ounce (30 grams).
Use Strong Flavors: Choose strongly flavored varieties like a sharp, aged cheddar or feta, so you can use less cheese to achieve a satisfying taste.
Avoid Processed Cheese: Steer clear of processed cheese slices, canned cheese, or cheese spreads, which often contain high levels of phosphate additives and sodium.
Read Labels Carefully: Always check the ingredient list for hidden potassium additives, such as potassium chloride, which are sometimes used in low-sodium products.
Incorporate into Recipes: Use cheese as a garnish rather than the main event. Sprinkle grated parmesan on pasta or crumble feta on a salad to get the flavor without overdoing the portion size.
Talk to a Dietitian: Work with a renal dietitian who can help tailor a diet plan to your specific health needs, including individual potassium, phosphorus, and sodium limits.

Conclusion: Cheese Can Be Part of a High-Potassium Diet

In conclusion, having high potassium does not mean you must completely give up cheese. By being mindful of your choices, focusing on low-potassium, unprocessed varieties like goat cheese, Swiss, and feta, and controlling your portion sizes, you can still enjoy cheese safely. However, it is crucial to remember that phosphorus and sodium are also key factors to manage, especially for those with kidney disease. Checking nutrition labels for hidden additives and monitoring intake are essential habits. With informed choices and the guidance of a healthcare professional, cheese can remain a flavorful and enjoyable part of a balanced, kidney-friendly diet.

Frequently Asked Questions

Soft goat cheese and grated parmesan are among the cheeses with the lowest potassium content per serving. Goat cheese provides just 7 mg of potassium per ounce, making it one of the safest options.

Regular cottage cheese can be quite high in potassium and sodium, with half a cup providing around 149 mg of potassium. However, low-sodium or 'no salt added' versions have significantly less and are a better option for those on a restricted diet.

It is not advisable to eat cheese daily, especially if you have high potassium or kidney disease. It's best consumed occasionally and in small, controlled portions to manage overall intake of potassium, phosphorus, and sodium.

You don't need to avoid all dairy, but you should be selective. Milk and yogurt are generally higher in potassium, while certain cheeses like goat cheese and Swiss are much lower. Portion control is key for all dairy products.

Yes, processed cheeses should be avoided on a low potassium diet. They are typically very high in sodium and contain phosphate additives, which are harmful for kidney health.

While it's not possible to remove potassium from cheese, you can 'leach' potassium from high-potassium vegetables like potatoes by boiling them in a large amount of water. This method is not applicable to cheese, so choosing low-potassium varieties is the best strategy.

The best types of cheese for kidney health are those low in potassium, phosphorus, and sodium. Good options include soft goat cheese, Swiss cheese, and low-sodium cottage cheese. Parmesan in small amounts can also be a good choice.
