Importance of Potassium for Kidney Health

Our kidneys work hard to regulate minerals in our systems, such as potassium. If your kidneys aren’t operating properly, the potassium can build up in the blood and cause symptoms such as muscle weakness, irregular heartbeat and potentially significant heart problems. Low potassium diets allow your kidneys to do their job and keep your heart in excellent condition.

Fruits: Apples, grapes, berries, peaches, plums, pineapples

Vegetables: Cabbage, cauliflower, cucumbers, green beans, lettuce, onions

Grains: White rice, pasta, bread (no whole grain or bran)

Proteins: Egg, chicken, turkey, fish (in small quantities)

Snacks: Popcorn (plain), crackers, cakes (no chocolate or nuts)

Remember, portion size still counts, too much of even low potassium foods can add up!

CKD Food Database: Using the Phosphorus, Sodium & Potassium Risk

There is more to choosing the correct foods than just potassium. The CKD food database is a useful tool for ranking foods according to their phosphorus, salt, and potassium concentrations. Here's how to utilize it:

See the foods before you consume them—look up the minerals in them.

Favor foods with "low" ratings in all three areas.

Develop recipes that are delicious and kidney-friendly.

Frequently Asked Questions

Only in moderation, and after leaching (soaking and boiling) to minimize potassium.

Bananas for CKD patients?

No, bananas are high in potassium and should be avoided or consumed sparingly.

Why do I have to monitor phosphate and salt too?

Too much phosphorus can weaken bones, and too much salt can raise blood pressure, both of which are hazards for CKD.
