Brown Rice
Like whole wheat bread, brown rice is a whole grain with higher levels of potassium and phosphorus than white rice. One cup of cooked brown rice has 150 mg of phosphorus and 154 mg of potassium. 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’re nutritious and have less phosphorus.
Banana
Everyone seems to know that bananas have high levels of potassium, right? While they naturally have low sodium amounts, one medium banana has 422 mg of potassium. If you eat a banana every day, it could be a challenge to keep your potassium intake under 2,000 mg a day. Unfortunately, plenty of other tropical fruits also have high amounts of potassium. However, pineapples have less potassium than other tropical fruits and can be a better alternative.
