Overview

The low oxalate diet is a diet that limits oxalate-rich foods. Oxalate is found in most plant-based foods and is common in the diet. When too much oxalate builds up in the kidneys, it can cause conditions like kidney stones.

The low oxalate diet is used for kidney stones and vulvar pain, but there is no good scientific evidence to support its use for any condition.

The low oxalate diet reduces the intake of foods that are high in oxalate. Oxalate is a normal part of the diet. But too much oxalate in the urine can cause it to build up and cause conditions like kidney stones. In theory, eating less oxalate should reduce the amount of oxalate in the urine. But some research suggests that the amount of oxalate in the diet doesn't always affect the amount of oxalate in the urine.

Uses & Effectiveness

Insufficient Evidence for

  • Kidney stones. Some early research shows that eating a low oxalate diet is no better than following another diet called the Dietary Approaches to Stop Hypertension (DASH) diet. Also, some research in healthy adults shows that eating less oxalate does not always lead to less oxalate in the urine.
  • Vulvar pain. Early research shows that women with vulvar pain do not have higher levels of oxalate in the urine. But some women with vulvar pain might have less pain after following a low oxalate diet.
  • Other conditions.

More evidence is needed to rate the low oxalate diet for these uses.

Side Effects



Special Precautions and Warnings



The low oxalate diet is LIKELY SAFE when followed appropriately for up to 3 months. No side effects have been reported.

Pregnancy and breast-feeding: There isn't enough reliable information to know if the low oxalate diet is safe to use when pregnant or breast-feeding. But there is no reason to expect safety issues as long as nutritional needs are met.

Interactions

Dosing

The low oxalate diet requires a person to increase water intake and limit intake of foods that are high in oxalate. Oxalate is found in plant-based foods. But online references don't always agree about the oxalate content of most foods. So, it can be hard to figure out which plant-based foods are highest in oxalate.
