Potatoes
One medium-sized potato with the skin still intact contains just under 20 percent of your daily needs of potassium. This is more than double the amount a medium-sized banana provides! Let’s say you were really hungry and ate a large potato instead. That would get you one-third of your daily needs of the mineral. Add more potatoes into your weekly meal prep to maintain healthy potassium levels to steer clear of high blood pressure and, ultimately, a stroke.
