LOW OXALATE DIET

Kidney stones are caused by a buildup of minerals in the urine. Calcium, oxalate (OXuh-layt), and uric acid may lead to kidney stones in some people. A low-oxalate diet is for people who have calcium oxalate kidney stones. Cutting back on high-oxalate foods and salt (sodium) and drinking plenty of water may help prevent kidney stones from forming.

Here are some important points to remember:

  • Oxalates are found in a wide variety of foods.
  • Foods that come from animals usually have little or no oxalate.
  • Drink plenty of fluids. Drink more than 8 cups of fluid every day. Your urine should be as clear as water. If it isn’t, drink more fluids.
  • To help prevent oxalate stones from forming, limit oxalates to 40 to 50 mg per day. Use the chart below as a guide.
  • Low-oxalate foods have less than 2 mg of oxalate per serving. You can eat as much of these foods as you like.
  • Moderate-oxalate foods have 2 to 6 mg of oxalate per serving. You should eat no more than three of these foods per day.
  • High-oxalate foods have more than 7 mg of oxalate per serving. Avoid these foods.
