Brown Rice
Just like whole-wheat bread, brown rice is a whole grain that has a higher potassium and phosphorus content than white rice. Just one cup of cooked brown rice contains 150 mg of phosphorus and 154 mg of potassium, while one cup of cooked white rice has only 69 mg of phosphorus and 54 mg of potassium. Some good substitutes for rice are bulgur, buckwheat, pearled barley, and couscous since they are nutritious and have less phosphorus.
Banana
It seems like everyone knows that bananas have high levels of potassium. While they’re naturally low in sodium, one medium banana has 422 mg of potassium. It could be difficult to keep your daily potassium intake under 2,000 mg if you eat a banana every day. Unfortunately, a lot of other tropical fruits have high potassium contents as well. Even so, pineapples contain a lot less potassium than other tropical fruits and can be a more suitable alternative.
