There is no cure for chronic kidney disease (CKD). It is important that you have regular follow up with your physician and make sure your blood pressure and treatment is appropriate for slowing the progression of your CKD. As far as diet is concerned, I am a strong advocate for the DASH diet. You can review the DASH diet at: https://www.nhlbi.nih.gov/health/health-topics/topics/dash
You should follow a low salt DASH diet and maintain a healthy body weight and exercise on a regular schedule.
