7. Black Beans
Chances are you’re already buying canned black beans for a boost in fiber and protein—two nutrients that keep you feeling full longer. However, they’re also a great source of potassium. Eat 1 cup and you’ll get 611 mg of the mineral, says Syn. Black beans also offer some calcium, magnesium, and folate.
8. White Beans
White beans might be the best source of potassium in the grocery store: A single cup has a whopping 1,000 mg, Syn says. That’s a full quarter of what you need every day. That same 1-cup serving also packs an impressive 17 grams of protein and 11 grams of fiber.
