Kidney stones have been on the rise in the U.S. for the past 30 years. A new study has found that a diet known to reduce blood pressure may help.

The "dash diet" is one that is high in fruits, vegetables, nuts and dairy products. It's also low in red meat and sugary drinks.

This new study has found that the combination of foods may help reduce the risk of kidney stones.

Researchers say people who followed the dash diet had higher concentrations of citrate an important salt that prevents calcium stones.

It's believed the lower rate of kidney stones could be due to higher water content in dash-type foods.
