A study published in the Clinical Journal of the American Society of Nephrology suggests that consuming a Mediterranean diet may aid kidney health in kidney transplant recipients. The researchers examined the dietary intake of 632 adult kidney transplant recipients using a 177-item validated food frequency questionnaire. Adherence to the Mediterranean diet was assessed using a nine-point Mediterranean Diet Score. Primary end point of the study was graft failure and secondary end points included kidney function decline and graft loss.

During a median follow-up of 5.4 years, 76 participants developed graft failure, 119 developed kidney function decline, and 181 developed graft loss. The researchers found that the Mediterranean Diet Score was inversely associated with all study end points—graft failure, kidney function decline, and graft loss. In fact, for every two-point increase in the Mediterranean Diet Score, there was a 29% lower risk of kidney function decline and a 32% lower risk of kidney failure.
