I found a great link with food sources that you can choose from. Excellent sources of potassium include chard, mushrooms, and spinach. Very good sources of potassium include fennel, kale, mustard greens, Brussel sprouts, broccoli, winter squash, eggplant, cantaloupe, and tomatoes. Good sources of potassium include parsley, romaine, cucumber, bell pepper, turmeric, apricots, ginger root, strawberries, avocado, banana, tuna, halibut, cauliflower and cabbage.
Food sources of potassiumI mostly have the salad greens listed along with tomatoes and bananas but as the weather has heated up and I'm perspiring more I've noticed the leg cramps, too. Your post made me realize I need to up my tomato intake. Low cal and high potassium.
