What Are Oxalates?

Oxalates or oxalic acid are natural organic acids or molecules found in many plants and animals, and help regulate minerals like calcium.

In humans, oxalates come from two sources:

  1. Foods we eat, including spinach, rhubarb, nuts, and beans
  2. Internal production by intestinal bacteria during metabolism, when the body makes or breaks down vitamin C, amino acids, and thyroid hormones.

Oxalates can also be produced by yeast that grows on certain foods like bread with seeds or nuts that have not been properly stored at low temperatures between 35°F (1°C) and 45°F (7°C).

But the highest concentration of oxalates is in raw foods. For example, spinach salads topped with grated cheese can result in up to 300 milligrams of oxalates per serving.

When we consume oxalates, they can attach to minerals such as calcium in the gut. When this attachment or binding is properly done, oxalates are excreted in the stool.

If not, oxalates can enter the bloodstream and be eliminated through urine. In some cases, oxalates can crystallize with calcium in the kidneys, making calcium oxalate stones [1].

Different people metabolize oxalates differently. Your gut health, hydration, mineral intake, genetics, and medical conditions can all influence how the body handles oxalates.

But does this mean oxalates are bad for our bodies, and we just need to get rid of them?

Are Oxalates Bad for You?

Oxalates are not naturally bad for everyone. In fact, many high-oxalate foods, such as leafy greens, nuts, and berries, are rich in vitamins, fiber, and antioxidants.

However, oxalates can cause problems for people who:

  • Have a history of calcium oxalate kidney stones
  • Have hyperoxaluria (a condition where you excrete excessive oxalates)
  • Experience fat malabsorption, like inflammatory bowel disease, or bariatric surgery
  • Consume very high amounts of high-oxalate foods without enough calcium

In these people, oxalates can interrupt mineral absorption and increase urinary oxalate levels. It means oxalates can combine with calcium in the urine to form crystals, raising the risk of kidney stone formation.

Oxalates

Oxalates are not bad for you in small amounts but can be harmful if you have too much.

Also, high levels of oxalates in the gut can bind with minerals like calcium, iron, and magnesium, making them less available for absorption by the body and causing nutrient deficiencies.

Additionally, oxalates can irritate the digestive tract, causing bloating, gas, and diarrhea in some people. Oxalates can also bind with medications like antibiotics and antacids, reducing their effectiveness.

So, before learning how to flush oxalates from body and avoiding these problems, we need to find out whether we are eating excess amounts of oxalates.

Symptoms of Overeating Oxalates

The difficult part of dealing with oxalates is that there are no clear symptoms, and sometimes the inflammation can be asymptomatic.

However, if you feel any of the symptoms below, it might be best to follow a meat-only lifestyle to heal.

  • Brain fog
  • Fatigue
  • Anxiety
  • Depression
  • Pain
  • Recurring kidney stones
  • Poor circulation
  • Swollen joints
  • Gum inflammation

Since it is difficult to decide whether the symptoms are due to overeating oxalates or not, it is best to avoid or minimize high-oxalate foods.

High Oxalate Foods

Foods high in oxalates are concentrated plant foods, especially when eaten raw or in large quantities. Cooking methods such as boiling can significantly reduce the oxalate content by 30-50%, especially in leafy greens.

The table below shows the high-oxalate foods. Those labeled “very high” in oxalates are limited or avoided in a low-oxalate diet, especially for those with a history of calcium oxalate kidney stones.

Oxalate values are shown per 100 grams of food unless mentioned otherwise.

FoodApproximate Oxalate ContentOxalate Level
Spinach (raw) 600-970 mg Very High
Spinach (cooked, boiled) 500-750 mg Very High
Swiss chard 650-860 mg Very High
Rhubarb 500-800 mg Very High
Almonds 400-470 mg High
Cashews 250-325 mg High
Beets (raw) 120-150 mg High
Sweet potatoes (baked) 90-140 mg Moderate-High
Dark chocolate (70-85 percent) 120-230 mg High
Tofu 250-350 mg High
Soy milk 30-60 mg per cup Moderate-High
Black tea 40-60 mg per cup Moderate
Green tea 15-30 mg per cup Moderate
Quinoa (cooked) 70-100 mg Moderate-High
Buckwheat 130-160 mg High
Wheat bran 400-450 mg High
Strawberries 10-15 mg Moderate
Blackberries 20-30 mg Moderate
Kiwi 15-25 mg Moderate
Concord grapes 10-20 mg Moderate
Figs (dried) 40-50 mg Moderate
Miso 30-50 mg Moderate
Okra 55-60 mg Moderate-High

People prone to kidney stones do not necessarily have to eliminate these foods, but can benefit from eating less of these foods and maintaining proper mineral balance.

Additionally, these individuals or almost all people can consume the following low-oxalate foods instead of these risky food sources.

Low Oxalate Foods

Consuming low-oxalate foods is good for everybody, especially for people who are dealing with recurrent kidney stones or hyperoxaluria. Oxalate level classification includes:

  • Low-oxalate: <10 mg per serving
  • Moderate-oxalate: 10-50 mg per serving
  • High-oxalate: 50-200 mg per serving
  • Very high-oxalate: >200 mg per serving

According to this classification, we can consider the following vegetables and fruits low in oxalates. Oxalate values are shown per 100 grams of raw food unless noted otherwise.

Vegetables and FruitsApproximate Oxalate ContentOxalate Level
Lettuce (iceberg/romaine) 0-2 mg Low
Zucchini 2-4 mg Low
Cabbage (green) 0-3 mg Low
Cauliflower 1-4 mg Low
Mushrooms (white/button) 0-2 mg Low
Apples 0-2 mg Low
Bananas 3-5 mg Low
Blueberries 2-4 mg Low
Grapes 0-2 mg Low
Melons (watermelon, cantaloupe, honeydew) 0-2 mg Low

Low-oxalate fruits are generally recommended because they provide hydration, fiber, and antioxidants without significantly increasing oxalate load.

However, consult your dietitian or healthcare specialist for personalized advice based on your health, diet, and goals.

An Excellent Way to Dump Oxalates

An excellent way to flush oxalates out of your body is by following a Carnivore Diet for several weeks or months at a time.

How to Flush Oxalates from Body Using a Carnivore Diet?

If you are not already following a Carnivore Diet Meal Plan, I'd highly recommend giving it a try. If done right and with minimal cheating, you will get great results!

The Carnivore Det can help you flush oxalates by avoiding irritants and inflammatory plant-based foods and consuming high-quality animal-based products, especially meat.

On this low-carb, animal-based diet, you need to avoid all plant matter from your meals, including fruit juices, smoothies, and drinks made with leafy greens like kale or spinach, because they contain high concentrations of oxalates.

A meat-only diet like Carnivore is highly nutritious and extremely low in inflammation and toxins. This is because when you are eating nothing but meat and animal fat, you are consuming fewer vegetables, fruits, nuts, and seeds, which are the main sources of oxalates [2].

When you remove other major sources of toxins from your diet, then there is not much left to be excreted through your body.

[cta-gocarnivore-plans]

And since there is no need for your body to expel these excess metabolites anymore, they can just sit in your system until they leave on their own accord or get absorbed by other nutrients like vitamin C or magnesium.

You can learn more about the Carnivore Diet and Carnivore Diet Results.

In addition to going on a Carnivore Diet, you can use the techniques below to flush oxalates from your body.

Drink Plenty of Water

Drinking plenty of water can increase the speed at which oxalates are removed from the body through the urine.

Consume More Calcium

Calcium can bind to oxalates in the intestines, preventing them from being absorbed into the bloodstream.

Limit High-Oxalate Foods

Limiting foods that are high in oxalates, such as spinach, beets, rhubarb, nuts, and chocolate, can help reduce oxalate levels in the body and prevent more oxalatefrom entering your body.

Consume More Magnesium

Magnesium can help reduce oxalate absorption in the gut.

Use Probiotics

Some studies suggest that consuming probiotics can help break down oxalates in the gut, reducing their absorption into the bloodstream.

However, you need to be mindful of oxalate dumping, which can occur after eating large quantities of oxalates and suddenly reducing the intake.

What Is Oxalate Dumping?

Oxalate dumping can occur when you suddenly decrease the oxalate intake. When this happens, the stored oxalates can be released from tissues and excreted through urine, stool, or sweat.

When you eat foods high in oxalates (like rhubarb), your body gets rid of them by releasing them into your intestine, where they pass through the digestive tract without being absorbed or metabolized by your body, which means they do not pose any nutritional value!

Although healthy and useful for the body, this condition can cause symptoms like diarrhea, vomiting, and abdominal pain.

Oxalate Dumping Symptoms

  • Temporary fatigue
  • Digestive changes like loose stools or constipation
  • Urinary discomfort
  • Joint stiffness
  • Skin rashes or itching

However, please note that these symptoms are non-specific and can occur for many reasons, including electrolyte shifts, dehydration, or dietary changes. But if you experience persistent or severe symptoms, you should seek medical help.

It is common for people with an underlying kidney condition called primary hyperoxaluria to have problems with toxic buildup in their urine.

If that build-up becomes too high and spills into the gut, a condition called intestinal hyperoxaluria, it can result in kidney stones or other complications.

However, if you have a healthy digestive system, your body usually processes oxalates, so they do not cause problems for you.

How Long Does Oxalate Dumping Last?

This can take a while! Depending on your level of intoxication and how long you have been consuming these poisonous foods.

For some, it can take a few months, and for others, it can take even over 10 years until they feel they have achieved complete elimination.

The best treatment is to follow a low-inflammation elimination diet like a Carnivore or Lion Diet.

How to Reduce Oxalates Safely?

Rather than “flushing” oxalates aggressively, most experts recommend reducing oxalate load gradually and safely. The best strategies include the following:

  • Stay hydrated. Drinking enough water and fluids dilutes urinary oxalates.
  • Consume calcium with meals because calcium binds to oxalates in the gut.
  • Cook high-oxalate foods. Boiling reduces oxalate content.
  • Avoid excessive vitamin C supplementation.
  • Maintain gut health. Certain bacteria may help degrade oxalates

Who Should Follow a Low Oxalate Diet?

A low-oxalate diet can be beneficial for:

  • Individuals with recurrent calcium oxalate kidney stones
  • Those diagnosed with hyperoxaluria
  • People with fat malabsorption disorders

It is no secret that you need to consult your healthcare provider before changing your diet to get personalized advice based onyour health status, needs, and goals.

The Bottom Line

Oxalates are a normal part of many healthy foods and are not dangerous for most people. However, oxalates can be a big problem for people who have a high-inflammatory diet.

Individuals with kidney stones or specific metabolic conditions can benefit from managing oxalate intake through proper dietary strategies.

Following a Carnivore Diet and eliminating high-oxalate, inflammatory foods can help you flush them out of your system and keep them under control.

Rather than fearing oxalates, focus on moderation, hydration, mineral balance, and individualized care, the same principles supported by leading medical experts.
