Hypertension diet may reduce kidney stones

September 20, 2010
A diet aimed at lowering blood pressure may also prevent the formation of kidney stones, according to a new study published in the Clinical Journal of the American Society Nephrology.

Researchers studied urine samples from 3,426 individuals involved in several long-term studies and determined that following the Dietary Approaches to Stop Hypertension (DASH) diet can reduce kidney stones. The DASH diet is high in fruits, vegetables, nuts and legumes, dairy products and whole grains, and is low in sweetened beverages as well as red and processed meats.

The diet may also help people who have a history of forming kidney stones. "We believe our results provide a strong rationale for a randomized trial examining the effect of a DASH-style diet on kidney stone recurrence," according to the study led by Dr. Eric Taylor of the Brigham and Women's Hospital in Boston.

People who follow the DASH diet tend to urinate more frequently and their urine contains more citrate, which is an inhibitor of calcium stones.

The Division of Kidney Diseases and Hypertension at both the North Shore University Hospital and the Long Island Jewish Medical Center, the research hospitals of the North Shore-LIJ Health System, have comprehensive medical services and research programs on both diabetic and polycystic kidney disease.
