In general, high potassium-containing foods include whole unprocessed foods, white potatoes with skin, sweet potatoes, tomatoes, bananas, oranges, other fruits and vegetables, dairy products, and legumes.

For specific amounts, go to www.nutritiondata.com. On the home page, look at Nutrition Management Tools; then select Foods by Nutrient.  From here you can choose potassium and various food categories for analysis of exactly how much potassium is found in each food.  I hope this helps and thank you for your inquiry.
