In kidney transplant recipients, does reducing dietary salt intake compared to usual salt intake improve clinically relevant outcomes and decrease adverse effects?
A Cochrane review by Palmer SC et al. (2019) investigated the effects of dietary interventions for adults with chronic kidney disease. The review included 11 randomized controlled trials (RCTs) with a total of 590 participants. The findings suggest that dietary interventions may have a beneficial effect on some outcomes, including the reduction of systolic and diastolic blood pressure (BP) and improvement in quality of life. However, there was insufficient evidence to draw any conclusions about the effects of dietary interventions on other outcomes, such as sodium excretion, serum creatinine, and body mass index. Therefore, further studies are needed to determine the effect of dietary interventions on these outcomes in kidney transplant recipients.
