What is a Low Oxalate Diet?
Oxalate, also called oxalic acid, is a naturally occurring compound found in many plants. Our bodies are able to produce it organically or may obtain it from food.
Many so called “health foods” like spinach, soy, almonds, and cacao contain exceptionally high levels of oxalate.
In moderate amounts these foods may not cause any problems. However, if eaten in excess or consumed by someone who already has autoimmune conditions or severe gut dysfunction, problems can arise.
Oxalate toxicity may be experienced as
- Kidney stones
- Back and joint pain
- Leaky gut
A low oxalate diet is a diet that minimized the intake of oxalate containing foods.
This is a field of research that we are only beginning to understand. There is not a hard definition of what counts as low, medium, and high oxalate. (3)
You may review multiple oxalate food lists and first see some foods marked low but then categorized as high somewhere else.
When questions occur, we can always do our best and judge the results by how our body reacts.
The University of Chicago set a limit of 100 mg oxalate a day for low oxalate diets. That’s a maximum, they state that half that amount, 50 mg, is ideal if that can be accomplished.
Who Needs a Low Oxalate Diet?
Health care providers and dietitians also recommend a low oxalate diet to those who have noticeable urine oxalate levels. (6)
Now, in the day and age of the internet, you can find anecdotal evidence for all sorts of things. There are claims that a low oxalate diet can help with a multitude of symptoms:
- Chronic joint pain
- Chronic back pain
All things considered, testing a low oxalate diet yourself seems pretty safe. Continue learning about it and educate yourself through research and critical analysis.
Then when you are ready, swap one food for another and see if your symptoms improve.

Keto Low Oxalate Recipes
Some people come across low oxalate diet information after transitioning to a keto diet.
Entering into ketosis naturally eliminates many of the high oxalate foods from the diet. No one eats wheat, corn, soy, potatoes or beans on a ketogenic diet.

A low carb low oxalate diet may be a step in the right direction.
It is interesting to note that animal foods are the only foods that contain ZERO oxalic acid.
Have you ever heard of a carnivore diet?
This is a diet made exclusively from animal foods. It’s quite a fascinating concept and is widely considered to be a very effective reset diet that functions by eliminating all possible irritants.
Low Oxalate Diet Plan
Our daily habits are seriously challenged whenever we employ dietary changes. This is totally understandable because so many of our routine habits revolve around meal prep.
I recommend picking 3 breakfasts, 3 lunches, and 3 dinners that will fit into your diet plan. Make these your new favorite meals and rotate them around during the week.
Start the day with a breakfast of fatty animal foods. Choose a healthy source of protein and fat. You’ll be well satiated all morning long.
Salads are still fine for lunch. Opt for lettuce rather than spinach and add wild-caught fish, hard boiled egg, or steak on top. Sliced mushrooms and cucumber, are also delicious additions.
For dinner, avoid pasta and potatoes. Instead serve beef, chicken, or fish with a side of low oxalate friendly vegetables.
Many of these meals are naturally low in carbohydrate so since you are already going in that direction, it is a good time to try a low carb, high fat ketogenic diet to see if that will further improve your health.
