If you have chronic kidney disease (CKD) or are on dialysis, choosing the right low potassium foods is essential for protecting your heart and maintaining safe blood levels.

When kidneys are not working properly, potassium can build up in the bloodstream. This condition, called hyperkalemia, can be dangerous – which is why understanding which foods are lower in potassium can make a major difference in your health.

Why Low Potassium Foods Matter in Kidney Disease

Healthy kidneys filter excess potassium from the blood. With kidney disease, that process becomes less effective.

High potassium levels can cause:

• Muscle weakness

• Numbness or tingling

• Irregular heartbeat

• Heart complications

That’s why many CKD and dialysis patients are advised to follow a diet focused on low potassium foods.

Generally, low potassium foods contain 200 mg or less per serving. Portion size always matters.

💡 Tip: Boiling vegetables and draining the water can reduce potassium levels.
