Eating low-fat dairy products and plants could help protect against kidney stones, research showed.
A diet designed to prevent high blood pressure -- high in fruits, vegetables, nuts, dairy products and whole grains, and low in sweetened drinks and red and processed meats -- reduces the risk of developing the condition, a study found.
Researchers in the US studied urine samples from 3,426 people with and without a history of kidney stones.
Kidney stones, which are hard lumps of crystal formed by the waste products in the kidneys, are quite common and can cause severe pain.
