Oxalates are phytonutrients that exist in certain vegetables, fruits, nuts and grains in nature for their protection. It prevents most bugs and invasive natural enemies to such produce from eating them by hurting their teeth or means of taking in the product. It is nature's way of protecting such foods and allowing them to grown and exist.

Usually, if there is any discomfort or issue with the gut in intestinal tract, foods that are high in oxalates would be hard to process and handle for the system--thus the need for them to be either avoided or eaten in smaller amounts (depending on your particular case and need). If you are experiencing health issues in such areas it is best to avoid foods with oxalates in general. Other than that, usually, the body can handle and process certain amounts of oxalates.

VERY HIGH OXALATE (over 50mg per serving)

These foods, in general, could contain very large amounts of oxalate that would be in the range of 50 to 520 mg of oxalate per serving. Of course, any natural produce and it's ingredients or nutrients would largely depend on how it is grown, it's soil and environment. These are pretty accurate estimates though.

The following foods may contain very large amounts of oxalate in the range of
50 - 520mg oxalate per serving size listed.
