Beverage choice matters when it comes to kidney stones

To prevent kidney stones, doctors recommend increasing urine volume by drinking plenty of fluids -- two to three liters a day. Water is always a good choice; it's plentiful, inexpensive and zero calories per serving. Studies show that individuals who drink coffee and beer have a decreased risk of kidney stones. One study found that orange juice was better than other citrus juices, such as lemonade, in raising levels of citrate in the urine and reducing the formation of stones.
