1. Baked Potatoes
Tubers are the top source of potassium overall. One medium baked potato contains nearly 900 milligrams — about 25% of the daily recommended amount — and packs almost 5 grams of filling fiber.
2. Sweet Potatoes
This other root vegetable doesn’t skimp on potassium either, with 694 milligrams in one sweet potato. That’s about 15% of the daily recommended amount at just 131 calories, not to mention all the beta carotene and vitamin A you get in each yam.
