Comparing minimally processed and ultra-processed diets for kidney health
Part of Hormones & metabolism, Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares two diets—one with minimally processed foods and one with ultra-processed foods—to see how they affect potassium levels in people with chronic kidney disease. You will receive all meals during the study, and the results may help guide dietary advice for better kidney health.
