Top Potassium-Rich Foods Beyond Bananas

While bananas are the most widely recognized source of potassium, nutrition experts indicate that many other fruits, vegetables, and proteins provide significantly higher concentrations of the essential mineral.

Potassium is critical for the function of the heart, kidneys, muscles, and nerves. According to registered dietitian Anna Taylor, RDN, LD, a diet rich in potassium and low in sodium may reduce the risk of stroke and high blood pressure.

The mineral helps regulate sodium levels, moves nutrients into cells, and allows nerves and muscles to communicate with each other. Low potassium levels are associated with an increased risk of high blood sugar, kidney stones, and high blood pressure.

Other benefits include maintaining the balance of fluids and muscles in the body, reducing bone loss, and mitigating the harmful effects of salt.

Recommended Daily Intake

The U.S. Food and Drug Administration (FDA) recommends a daily intake of 3,400 milligrams (mg) of potassium for men and 2,600 mg for women. The National Institutes of Health (NIH) provides a similar range, stating that adults should consume between 2,600 and 3,400 mg per day.

Despite these requirements, research suggests that current dietary intake only meets approximately 88% of the recommended daily requirement.

To help identify nutrient-dense options, Amy Lee, M.D., chief medical officer of Lindora L.L.C. And Pear Sports L.L.C., states that a food should contain more than 200 mg of potassium per serving to be considered high in the nutrient.

Foods With More Potassium Than Bananas

A medium banana contains approximately 451 mg of potassium. However, several other plant-based sources offer higher amounts per serving.

• Leafy Greens: One cup of cooked beet greens provides 1,309 mg, while one cup of cooked Swiss chard contains 961 mg.
• Tubers: A medium baked sweet potato contains 542 mg.
• Plantains: One cup of plantains provides 663 mg.
• Fruits and Vegetables: Watermelon, avocados, and tomato sauce are identified as sources that contain more potassium per serving than a banana.

Additional Potassium-Rich Sources

Beyond fruits and vegetables, legumes and proteins are effective ways to increase potassium intake. Black beans and lentils are noted as high-potassium options, as is salmon.

Other dietary sources include:

• Dairy and Proteins: Milk, meats, poultry, and nuts.
• Whole Grains: Brown rice and whole-wheat flour contain higher levels of potassium than white rice or refined white wheat flour.
• Beverages: Coffee, tea, and various nonalcoholic beverages are among the top sources of potassium for adults in the U.S.
