From the Guidelines
Potassium-rich foods include bananas, avocados, sweet potatoes, spinach, and white beans, which are essential for maintaining proper muscle function, nerve signaling, and blood pressure regulation. Other excellent sources are oranges, tomatoes, yogurt, salmon, and coconut water. Potatoes with skin, lentils, dried apricots, and milk also provide significant amounts of potassium. Nuts like almonds and pistachios, as well as dark chocolate, are good options too.
Key Points
- Incorporating these foods into your daily diet is crucial for overall health, as they each offer additional nutrients that support well-being.
- The recommended daily intake for adults is about 4700 mg of potassium, as suggested by the 2015 Dietary Guidelines for Americans 1.
- Eating a variety of these foods throughout the day is more beneficial than relying on a single source.
- If you have kidney disease, consult with a healthcare provider before significantly increasing potassium intake, as your body may have difficulty processing excess potassium 1.
Benefits of Potassium-Rich Foods
- Help maintain proper muscle function and nerve signaling
- Support blood pressure regulation
- Reduce the risk of cardiovascular disease, especially stroke 1
Important Considerations
- Individuals with kidney disease should limit their potassium intake to less than 2,000 to 3,000 mg per day 1.
- Potassium-rich diets can help lower blood pressure, especially in individuals with hypertension 1.
- A diet rich in potassium can also attenuate the blood pressure-raising effects of sodium 1.

From the Research
Potassium-Rich Foods
Some examples of potassium-rich foods include:
- Fruits, such as tomatoes and kiwi 3, 4
- Vegetables, including leafy greens like spinach and chicory, as well as root vegetables like potatoes and carrots 3, 4
- Legumes, such as peas and beans 3, 4
- Whole grains, like rice and wholegrain bread 3
- Dairy products and animal proteins 3
- Seeds, which tend to have higher potassium content than other parts of plants 4
Factors Affecting Potassium Content
The potassium content of foods can be affected by various factors, including:
- Cooking methods: boiling can reduce potassium content in some vegetables, but not others 4
- Processing: canned products tend to have higher sodium and lower potassium values than fresh or frozen products 5
- Type of plant organ: seeds and leaves tend to have higher potassium content than fruits or roots 4
Health Benefits of Potassium-Rich Foods
Consuming potassium-rich foods has been associated with several health benefits, including:
