Dietary Potassium Liberalization in Pre-Dialysis Patients

NCT05090865 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

Last updated 2026-01-16

No results posted yet for this study

Summary

The study will look at the impact of the potassium content in fruits and vegetables, on serum potassium concentrations in people with Chronic Kidney Disease (CKD) using a randomized crossover design. Participants will receive home delivery of fruit and vegetables with either higher or lower potassium content in a random order. Clinical chemistry markers from blood and urine samples, blood pressure, physical functioning and health related quality of life will be assessed throughout the duration of the trial. This study will also measure their physical functioning, using a chair stand test. The results of this study could change the dietary recommendations for people with CKD related to potassium.

Conditions

Interventions

DIETARY_SUPPLEMENT

Liberalized dietary potassium via fruits and vegetables

On the liberalized dietary potassium intervention, participants will receive groceries delivered to their houses that contain potassium rich fruit and vegetables, that contain more than 250 mg of potassium per typical serving. Participants will be instructed to incorporate the fruit and vegetables into their diet targeting a daily intake of 2000 mg of potassium a day from delivered fruit and vegetables, and a daily dietary potassium intake of 3500 mg.

DIETARY_SUPPLEMENT

Standard dietary potassium restriction

Participants will receive weekly supplementation of lower potassium fruit and vegetables, that deliver less than 200 mg of potassium per typical serving. Participants will be instructed to incorporate the fruit and vegetables into their diet targeting a daily intake of 500 mg of K a day from the box, and a daily dietary K intake \< 2000 mg. Participants will receive counselling from a registered dietician (RD) to reinforce the potassium restriction.
