DASH Diet May Prevent Kidney Stones
Study: DASH Diet, Designed to Cut High Blood Pressure, May Also Make Kidney Stones Less Likely
Aug. 14, 2009 -- Following the DASH diet may cut down on kidney stones as
well as improve high blood pressure.
That news comes from a study published online in the Journal of the
American Society of Nephrology.
Data came from more than 241,700 U.S. health care workers who completed
surveys about their diets every four years for up to 18 years.
Based on those dietary surveys, the researchers calculated a "DASH" score
for each participant.
The highest scores went to participants whose diets most closely matched the
Dietary Approaches to Stop Hypertension (DASH) diet, which is widely used to
lower hypertension (high blood pressure).
The following eating habits boosted DASH scores:
- Eating a diet rich in fruits, vegetables, nuts and legumes, low-fat dairy
products, and whole grains.
- Eating a diet low in sodium, sweetened drinks, red meat, and processed
People with the highest DASH scores were the least likely to develop kidney
stones, regardless of age, sex, BMI (body mass index), hypertension, diabetes,
use of medicines called thiazides, and intake of calories, fluid, caffeine, and
"Consumption of a DASH-style diet is associated with a marked decrease in
kidney stone risk," write the researchers, who included Eric Taylor, MD, of
Brigham and Women's Hospital in Boston.
