A study revealed that the DASH diet can not only reduce the kidney stones but can also improve high blood pressure.

241,700 U. S. health workers submitted their survey results every four years for up to 18 years.

The participants who most closely followed the Dietary Approaches to Stop Hypertension (DASH) diet were found to have benefited the most. The DASH diet is mostly used for lowering hypertension (high blood pressure).

The DASH diet followed a diet similar to this:- 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 meats.

Eric Taylor, MD, of Maine Medical Center in Portland, and colleagues said, "Although we think it reasonable for calcium oxalate stone formers with high levels of urinary oxalate to avoid intake of some individual foods very high in oxalate (such as spinach and almonds), our data do not support the common practice of dietary oxalate restriction in calcium stone formers, particularly if such advice results in lower intake of fruits, vegetables, and whole grains."

The results clearly showed that people with the highest scores had the least risk of developing kidney stones. All this is completely independent of other factors like age, sex, BMI (body mass index), hypertension, diabetes, use of medicines called thiazides, and intake of calories, fluid, caffeine, and alcohol.
