Low-Oxalate DietEn Español (Spanish Version)
Oxalates are naturally-occurring substances found in plants, animals, and humans. The kidneys excrete oxalates into the urine.
Eating a diet low in oxalates can reduce your risk of developing
. Kidney stones sometimes form when oxalates and calcium bind together. Decreasing the amount of oxalates that are present in the urine lowers this risk.
A low-oxalate diet usually limits oxalate intake to about 50 milligrams (mg) per day. Because oxalates are found in many different foods, it is important to become familiar with which foods are fine to eat in moderation and which foods should be avoided.
This chart from the American Dietetic Association spotlights foods that are either low or moderate in oxalates. If you have calcium stones, it is important to decrease your sodium intake, as well.
