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.

Once consumed, oxalate can bind to minerals to form compounds, including calcium oxalate and iron oxalate. This mostly occurs in the colon, but can also take place in the kidneys and other parts of the urinary tract.

Healthline

Usually, oxalate passes without a problem but if a person is oxalate sensitive or overloaded with a consistently high amount of oxalic acid, negative symptoms may occur. (1, 2)

Oxalate toxicity may be experienced as

  • Kidney stones
  • Vulvodynia
  • Back and joint pain
  • Headaches
  • 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?

Low oxalate diets are typically recommended in relation to kidney stones, not for weight loss. This dietary approach is known to help clear kidney stones and prevent them from forming in the first place. (4, 5)

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:

  • Fibromyalgia
  • Migraines
  • Fatigue
  • Chronic joint pain
  • Chronic back pain
  • Arthritis

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.

What foods are High in Oxalates?

Oxalate levels vary based on food type, cooking method, processing and growing factors. That being said, the foods with the highest level of oxalate are generally agreed upon. (7, 8, 9, 10)

I’m sorry if these are some of your favorites!

Foods with the highest oxalate levels are:

  • Spinach, cooked
  • Spinach, raw
  • Rhubarb
  • Rice bran
  • Buckwheat groats
  • Almonds
  • Miso soup

If you are concerned about oxalate, eliminate these foods entirely and start immediately.

Other high oxalate foods to avoid or limit are:

  • Whole wheat bread
  • Buckwheat flour
  • Collard greens
  • Okra
  • Eggplant
  • Beets and beet greens
  • Swiss chard
  • Sweet potatoes
  • Beans
  • Soy, tofu, and soy milk
  • Nuts and nut butters

Interestingly, kale is low in oxalate. There’s no need to limit it, if you love that leafy green.

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.
