Education and cooking methods in the management of calcium and PTH serum levels in patients on hemodialysis: a randomized controlled study.

Background: Chronic kidney disease associated mineral bone disorder (CKD-MBD) is one of the major causes of excess morbidity and mortality in hemodialysis patients. The purpose of this study was to investigate whether education about dietary intakes and specific food processing methods affect serum calcium and PTH concentrations in hemodialysis patients.

Methods: Forty-seven hemodialysis patients were randomly divided into a control and an intervention group.
