Limit Your Bananas

Like many other tropical fruits, bananas have a high dose of potassium, and as such, it is not recommended to have one each day if you have kidney problems. An average medium banana has roughly 422 mg of potassium, which is too much for one intake if you have a limit of 2,000 mg of potassium per day. Pineapple has a lot less and can be a substantial alternative for your fruit serving.
