When you think of the best sources of potassium, you probably default to bananas.

You’d think the tropical fruit has a monopoly on the stuff.

But the truth is, bananas are really nothing to write home about in the potassium department. Each medium fruit provides 422 mg of the mineral, or about 9% of your 4,700 mg recommended daily intake. Not too shabby, but you can easily do better. Just start with these 13 foods, all of which provide more potassium than your old yellow standby.
