Red meat consumption linked with increased risk of developing kidney failure
Choosing other protein sources may help preserve kidney health
American Society of Nephrology

A new study indicates that red meat intake may increase the risk of kidney failure in the general population, and substituting red meat with alternative sources of protein from time to time may significantly reduce this risk. The findings appear in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

Increasing numbers of individuals are developing chronic kidney disease (CKD), and many progress to end-stage renal disease (ESRD), which requires dialysis or a kidney transplant. Current guidelines recommend restricting dietary protein intake to help manage CKD and slow progression to ESRD; however, there is limited evidence that overall dietary protein restriction or limiting specific food sources of protein intake may slow kidney function decline in the general population.

After an average follow-up of 15.5 years, the researchers found that red meat intake was strongly associated with an increased risk of ESRD in a dose-dependent manner. People consuming the highest amounts (top 25%) of red meat had a 40% increased risk of developing ESRD compared with people consuming the lowest amounts (lowest 25%) No association was found with intakes of poultry, fish, eggs, or dairy products, while soy and legumes appeared to be slightly protective. Substituting one serving of red meat with other sources of protein reduced the risk of ESRD by up to 62%.
