Since most fresh veggies and fruits are high in potassium, it is better to limit their consumption. Some canned veggies or fruits may work well as long as you rinse and drain them. You can also eat some kinds of cheese as they are low in potassium compared to other dairy products. If you want to drink milk, go for rice milk or non-dairy options. Rather than eating bran and whole grains, choose bread baked from refined flour or rice cereals. Low-potassium snacks include puffed rice, unbuttered popcorn, and soda crackers. For protein, go for egg whites, nuts, or peanut butter.
