First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how potassium from fresh foods (like fruits and vegetables) versus processed foods affects blood potassium levels in people with chronic kidney disease (stages 3B-5). Participants will try four different 10-day diets, all provided for free, to see which foods are safest. The goal is to help doctors give better dietary advice so patients can eat healthy without risking high potassium.
