5 Foods with More Potassium Than a Banana

Potassium is a crucial nutrient, playing key roles in muscle strength, nerve function and heart health. And if you don't get enough—4,700 mg a day—it could lead to a deficiency, complete with fatigue, muscle cramps, heart palpitations and dizzy spells. Yikes.

You've probably heard that bananas are packed with potassium, which is true. This tasty staple is a great option for an ample dose of the nutrient, with 422 mg in each medium-sized serving according to the USDA Nutrient Database. But it's certainly not the only way to load up on this important mineral—or even the best way! Here, we've rounded up five foods with more potassium than a banana. Nosh away.
