If you have IC and your doctor hasn't tested you for hyperoxaluria please read on. This may be the cause of your IC or a significant contributor to your symptoms.

Oxalate Food List

Now that you have an understanding of what oxalates are, how they can cause or aggravate IC (see Hyperoxaluria and IC), and how they can be absorbed in excess into the body (see The Cause), the next step is to look at the levels of oxalates in food.

Oxalates can be found in all vegetables, fruits, nuts, grains and legumes. However the amount of oxalates in each food item varies greatly, from very low to very high. Below is a table to give you a basic overview of the level of oxalates in various foods.

NOTE: Unprocessed meat, fish and eggs contain negligible amounts of oxalate so are not included in the table. However, eating large quantities of meat can cause the body to make its own oxalates so this should be avoided.

*The level of oxalates in these foods varies according to cooking method. This is the lowest level these foods can be and it is after they have been boiled.
