Oxalates: What Are They & How to Manage Them

Oxalates: What Are They & How to Manage Them. I’m sure you’re thinking, “Wow, what is oxalate and why do I need to know about it?” right? Sure, its not something that many people think about, but if you have kidney issues, gout, rheumatoid arthritis or certain vulvar pain, you really should be avoiding foods that are high in oxalic acid. So let’s cover some facts.

Fact: Oxalate is made in plants, animals and humans, the highest levels are found in plants.

Fact: the function of oxalate is to help plants dispose of excess calcium.

Fact: Our bodies have no use for oxalate and it is disposed of in the urine.

It is estimated that 80% of kidney stones are formed from calcium oxalate – Wikipedia.

So, I’m going to try to do a quick run down of the basic Paleo foods that we eat and how high the oxalate count is in each. Keep in mind that species vary, so these are rough guidelines. Also keep in mind that we are not doctors and if you have any pre-existing conditions, they should be taken up with your physician. This guide is not a substitute.

A low oxalate diet is one that consists, generally, of less than 80mg per day. If you do eat a food that is high in oxalate, drink a glass of water before and after, to help flush the oxalates out of your system.

*Oxalate groups are based on ¼ cup servings (1 tsp for spices), unless noted otherwise in the table.
