I agree there are significant amount of foods that have potassium content but not that many that have high content in relationship to the RDA which is 4700 mg per day. For example, a high potassium food is banana. You would have to eat 12 bananas a day to get your RDA. This is why most all people are not getting the RDA of potassium from food - it does not seem easy to me. What do you eat to get 4700 mg per day in your diet?
