January 10, 2026 •

4 min read

According to the National Kidney Foundation, foods containing 200 milligrams or less of potassium per serving are considered low-potassium. Selecting the right fruits is a key part of maintaining this type of diet, which is often recommended for individuals with kidney-related health concerns.

Quick Summary

This article explores ideal fruit choices for a low-potassium diet, differentiating them from high-potassium options and providing practical tips for portion control and meal planning to help you manage your health.

Key Points

Best All-Around Fruit: Berries like blueberries, strawberries, and raspberries are versatile, antioxidant-rich, and consistently low in potassium.
Portion Control is Key: Even low-potassium fruits should be eaten in moderation, as larger servings can increase potassium intake significantly.
Avoid Dried Fruits and Bananas: Dried fruits and bananas are concentrated sources of potassium and should be limited or avoided on a restricted diet.
Consider Canned Options: For fruits like peaches and fruit cocktail, choosing canned and drained varieties can help lower the overall potassium content.
Apples are a Safe Staple: A medium apple is a reliable and safe choice, providing nutrients without a high potassium load.
Consult a Professional: Always seek advice from a doctor or dietitian before making significant changes to your diet, especially if managing a health condition like CKD.

Understanding the Role of Potassium in Your Diet

Potassium is an essential mineral that plays a vital role in the body, helping to maintain fluid balance, nerve signals, and muscle contractions. For most healthy individuals, a high-potassium diet is beneficial. However, for those with impaired kidney function, excessive potassium intake can be dangerous. When kidneys are unable to filter out excess potassium efficiently, it can build up in the blood, a condition known as hyperkalemia, which can impact heart rhythm. Therefore, a low-potassium diet is necessary for managing such conditions.

What Defines a Low-Potassium Fruit?

Fruits are categorized as low-potassium if they contain less than 200 mg of potassium per standard serving, which is typically half a cup. The key to including fruits on a low-potassium diet is not just choosing the right type but also being mindful of serving sizes. A large portion of a low-potassium fruit can quickly increase your intake to a moderate or even high level.

The Best Low-Potassium Fruit Choices

Fortunately, there is a wide variety of delicious and nutritious fruits that are low in potassium and can be enjoyed safely. Berries, for example, are an excellent choice. A half-cup serving of strawberries, blueberries, blackberries, or raspberries all contain low levels of potassium, ranging from approximately 57 to 116 mg. Apples are another fantastic staple, with one medium apple containing only about 158 mg.

Other great options include:

Grapes: A half-cup serving of grapes contains just 88 mg of potassium.
Cherries: A half-cup of fresh cherries contains about 160 mg of potassium.
Peaches: One small fresh peach has approximately 176 mg of potassium. Canned peaches, drained, can be even lower.
Pears: A small pear is a low-potassium choice, similar to a small peach.
Pineapple: Half a cup of fresh pineapple contains around 109 mg of potassium.
Watermelon: A one-cup serving of watermelon contains approximately 170 mg of potassium.
Mandarin Oranges: Half a cup of canned mandarin oranges is a great low-potassium snack.

Understanding High-Potassium Fruits to Avoid

To effectively manage your potassium intake, it is equally important to be aware of which fruits are high in this mineral and should be limited or avoided. These often include tropical fruits and dried varieties due to their concentrated nutrient content. Some of the most common high-potassium fruits to watch out for are bananas, avocados, oranges, mangoes, and dried fruits like raisins and dates. A single medium-sized banana, for instance, contains a significant amount of potassium, around 425 mg, which is more than double the potassium of a medium apple.

Low-Potassium Fruits in Your Daily Diet

Incorporating low-potassium fruits into your daily meals is simple and can add flavor and nutrients without compromising your dietary restrictions. For breakfast, you can top low-potassium cereal with fresh berries. For a snack, a small apple or a handful of grapes is perfect. You can also make a kidney-friendly fruit salad with a mix of pears, peaches, and grapes.

When buying canned fruit, always choose options canned in juice and be sure to drain the liquid before eating, as this can reduce the potassium content. Furthermore, remember that serving size is paramount. One standard portion of a low-potassium fruit is generally safe, but consuming multiple portions can accumulate a higher potassium load.

Comparing Common Fruits for Potassium Content


Fruit (Serving Size)	Potassium Content	Classification	Notes
Banana (1 medium)	~425 mg	High	Often cited as a high-potassium fruit; limit consumption.
Avocado (1/4 whole)	~250 mg	High	A moderate serving can contain significant potassium.
Apple (1 medium)	~158 mg	Low	A safe and versatile choice for most.
Strawberries (1/2 cup)	~127 mg	Low	A great source of antioxidants and fiber.
Orange (1 medium)	~237 mg	High	Avoid, or limit to smaller portions if advised by a professional.
Pineapple (1/2 cup)	~109 mg	Low	A good tropical alternative to mango or papaya.
Dried Apricots (5 halves)	~400 mg+	High	Dried fruits are highly concentrated in potassium.
Watermelon (1 cup)	~170 mg	Low	A hydrating and delicious option when portioned correctly.

Conclusion: Making Informed Fruit Choices

Navigating a low-potassium diet requires careful attention to food choices and portion sizes. While there is no single "best" fruit, the wide range of low-potassium fruits, including apples, berries, grapes, and pineapple, ensures that you can still enjoy delicious and nutritious options. The key is to be mindful of high-potassium fruits like bananas and dried fruits and to always consult with a healthcare professional or registered dietitian for personalized dietary advice. By making informed choices, you can manage your potassium intake effectively without sacrificing flavor or nutrition.
