Kidney stones are a common urinary tract disorder.\nCaused by a buildup of minerals in urine, kidney stones are pieces of stone-like material that form on the walls of the kidney.\nSome people have kidney stones made from calcium oxalate (OX-uh-layt). For these people, cutting back on salt and following a low-oxalate diet may help prevent kidney stones.\nWho’s at Risk for Kidney Stones?\nIn the United States, about 1 million people get kidney stones every year. Most stones are so small that they pass through the urinary system without pain.\nHowever, a large enough stone can cause extreme pain or urinary blockage. This requires treatment or surgery.\nKidney stones usually affect:\n\nPeople between the ages of 20 and 40.\nMen more often than women.\nPeople who have a family history of kidney stones.\n\nRELATED:\u00a0How Can I Avoid Getting Kidney Stones?\nA Low-Oxalate Diet Plan\nMany foods contain oxalate. On a low-oxalate diet, you should limit your oxalate to 40 to 50 mg each day. This may help prevent kidney stones.\nBe sure to drink plenty of fluids. People likely to get kidney stones should drink 8 to 13 cups of fluid each day.\nYour body may turn extra vitamin C into oxalate. Avoid high doses of vitamin C supplements (more than 2,000 mg of vitamin C per day).\nThe following charts will help you eat foods low in oxalate and avoid foods high in oxalate. Food and drink serving sizes are 3.5 ounces (100 grams), unless otherwise noted.\nEnjoy these low-oxalate foods and drinks\nEat as much of these low-oxalate foods as you like. Low-oxalate foods have less than 2 mg of oxalate per serving.\n\n\n\nDrinks\n\n\nApple cider\nApple juice\nApricot nectar\nBottled beer\nButtermilk\nCherry juice\nCola\nGrapefruit juice\nGreen tea\n\n\n\n\nHerbal teas (see below)\nLemonade\nLemon juice\nLimeade\nLime juice\nMilk\nOolong tea\nPineapple juice\nWine\n\n\n\n\nHerbal teas\n\n\nCelestial Seasonings (Sleepytime, Peppermint, Wild Forest Blackberry, Mandarin Orange Spice, Cinnamon, Apple Spice)\nR.C.
