Potassium-Rich Diet May Protect Diabetics Against Heart and Kidney Diseases

The most common complications of type 2 diabetes include kidney failure and heart disease. Diets rich in potassium may help protect the heart and kidney health of patients with type 2 diabetes, according to a new study. The study was published in the Clinical Journal of the American Society of Nephrology (CJASN).Individuals with type 2 diabetes are at increased risk of developing kidney failure and heart disease. To examine whether higher intake sodium and potassium are associated with these risks, Shin-ichi Araki, MD, PhD (Shiga University of Medical Science, in Japan) and his colleagues studied a group of 623 patients with type 2 diabetes and normal kidney function. Patients were enrolled between 1996 and 2003 and were followed-up until 2013.

Higher levels of urinary potassium excretion, which closely correlate with intake amounts, were linked with a slower decline of kidney function and a lower incidence of cardiovascular complications. Sodium levels were not associated with kidney or heart health during follow-up.

"For many individuals with diabetes, the most challenging part of a treatment plan is to determine what to eat. The results in our study highlight the importance of a diet high in diabetes nutrition therapy," said Dr. Araki.
