Oxalates are naturally occurring plant compounds that bind to minerals, such as calcium and magnesium, potentially leading to mineral deficiencies and the formation of calcium oxalate stones in the kidneys.
Discover who can benefit from avoiding high oxalate foods and learn what cooking techniques you can use to reduce oxalate levels in beans, legumes, nuts, and vegetables.
What is oxalate?
Oxalate is an organic acid that’s naturally found in a wide variety of plant foods such as leafy green vegetables, legumes, nuts, seeds, and certain grains.
Oxalic acid forms insoluble salts with calcium, magnesium, iron, and zinc, and plants utilize oxalates to store these minerals for later use.
While the mineral-binding properties of oxalic acid may benefit plants, oxalates are considered anti-nutrients as they also bind to minerals in the human body, which can have various negative health consequences.

Possible side effects of oxalate
Because oxalate forms insoluble salts with minerals, it can impair the intestinal absorption of essential nutrients such as magnesium, calcium, iron, and zinc, potentially leading to nutrient deficiencies.
Calcium binds readily with oxalic acid, which can contribute to the development of calcium oxalate kidney stones, a common type of kidney stone.
A study published in Renal Physiology suggests, “To limit calcium oxalate stone growth, we advocate appropriate hydration, avoiding oxalate-rich foods, and adequate calcium intake.”
There also is evidence that dietary oxalates can trigger gastrointestinal issues in sensitive individuals and most commonly are associated with bloating, gas, diarrhea, and abdominal pain.
Research published in Kidney International Reports suggests that excessive intake of dietary oxalates not only increases the risk of kidney stones but may also negatively impact bone health and bone mineral density due to lower calcium availability.
Who should avoid oxalate?
“Many foods high in oxalates are rich sources of nutrients and generally recommended as part of a balanced diet,” explains Dr. Berg. “However, for some people, the potential side effects of oxalates can outweigh the health benefits of consuming these foods.”
Individuals prone to developing kidney stones should avoid consuming high-oxalate food and consider following an oxalate-controlled diet.
Oxalates can trigger gastrointestinal issues, which can be problematic for those with inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), Crohn’s disease, or other digestive tract issues.
In addition, research published in the Asian Pacific Journal of Clinical Nutrition found that oxalosis, a health condition characterized by excessive oxalic acid buildup in the body, requires strict avoidance of oxalate-rich foods.
What is a low-oxalate diet?
A low-oxalate diet focuses on limiting dietary oxalate intake to no more than 50 milligrams daily.
Foods are typically classified into four groups based on their oxalate content:
• Low: 0 to 9 milligrams per serving
• Moderate: 10 to 25 milligrams per serving
• High: 26 to 99 milligrams per serving
• Very high: 100 milligrams or more per serving
It’s also recommended that individuals with oxalate sensitivity increase their intake of calcium-rich foods. Calcium can bind with oxalates in the digestive tract, which reduces their absorption and helps lower the risk of kidney disease and digestive issues.
Another important aspect of a low-oxalate diet is to avoid excessive intake of vitamin C, also known as ascorbic acid, which can be metabolized into oxalic acid in the body.
However, this typically refers to high doses of vitamin C supplementation and does not require limiting vitamin C-rich foods.
High oxalate foods
There are various plant foods with a high oxalate content, and it’s crucial to limit or avoid these foods on a low-oxalate diet.
Oxalate concentrations of foods with a high- or very-high oxalate content per one-cup serving:
Spinach (raw): 1,510 milligrams
Spinach (cooked): 1,312 milligrams
Rhubarb: 1,082 milligrams
Almonds: 441 milligrams
Cashew nuts: 352 milligrams
Baked potato (with skin): 194 milligrams
Navy beans: 155 milligrams
Beets: 152 milligrams
Okra: 114 milligrams
French fries: 102 milligrams
Yam: 80 milligrams
Rutabaga: 62 milligram
Turnip: 60 milligrams
Raspberries: 48 milligrams
Bamboo shoots: 35 milligrams
Mashed potato: 29 milligrams
Orange: 29 milligrams
Sweet potato: 28 milligrams
It’s almost impossible to remember the exact oxalate content of different foods, which can make meal planning on a low-oxalate diet challenging, and having an oxalate food list can be extremely helpful.

Low-oxalate foods
There are plenty of nutritious foods that have a low-oxalate content and are suitable for individuals following a low-oxalate diet.
Here’s the oxalate content of low-oxalate foods per one-cup serving:
Alfalfa sprouts: 0 milligrams
Endive: 0 milligrams
Lettuce: 0 milligrams
Onions: 0 milligrams
Radish: 0 milligrams
Flaxseeds: 0 milligrams
Bok choy: 1 milligram
Cabbage: 1 milligram
Cauliflower: 2 milligrams
Broccoli: 2 milligrams
Kale: 2 milligrams
Peas: 2 milligrams
Squash: 2 milligrams
White mushrooms: 4 milligrams
Cucumber: 4 milligrams
Brussels sprouts: 4 milligrams
Mung beans: 6 milligrams
Tips for reducing oxalate
In addition to limiting dietary oxalate intake, different food preparation and cooking methods can lower the oxalate concentration of various foods.
Boiling, blanching, or steaming oxalate-rich vegetables causes structural changes in cell walls, which helps release and break down some of the oxalates.
A study published in the Journal of Agricultural and Food Chemistry found that cooking can reduce oxalate content by up to 80 percent, depending on cooking temperature and duration.
Soaking certain foods high in oxalates, such as beans, lentils, nuts, and seeds, causes oxalates to leach into the water, which can significantly reduce oxalate concentrations.
Consuming foods high in oxalates in combination with calcium-rich foods such as dairy products, leafy green vegetables, or small fish with edible bones can inhibit oxalate absorption in the intestines and help minimize the potential adverse health impacts associated with oxalic acid intake.
Key takeaways
Oxalates are found in many plant foods and can increase the risk of calcium stone formation and individuals prone to kidney stones or digestive issues can benefit from avoiding high-oxalate foods.
A low-oxalate diet aims to limit oxalate intake to no more than 50 milligrams daily. In addition, boiling, blanching, or steaming oxalate-rich vegetables and soaking beans, legumes, nuts, and seeds can significantly reduce the oxalate content of these foods.
FAQ
1. What are the foods high in oxalate to avoid?
Foods high in oxalates to avoid on a low-oxalate diet include spinach, okra, beets, baked potato skin, beans, rhubarb, almonds, walnuts, and sesame seeds.
2. What foods neutralize oxalate?
While there are no foods that directly neutralize oxalate, calcium can bind with oxalic acid, which helps prevent the intestinal absorption of dietary oxalates.
Combining oxalate-containing foods with calcium-rich options can minimize the risk of oxalate-related health issues such as kidney stones, digestive problems, and nutrient deficiencies.
3. How do you flush oxalate out of your body?
Drinking plenty of water helps keep urine diluted, which lowers urinary oxalate concentrations and reduces the risk of kidney stone formation. Adequate hydration also promotes frequent urination, which helps excrete oxalic acid.
4. What are the symptoms of too much oxalate?
Common symptoms and health issues linked to excessive oxalate consumption are kidney stones, mineral deficiencies, gastrointestinal issues, painful urination, and joint pain.
5. Are eggs high in oxalate?
Eggs are oxalate-free. In addition, meat, poultry, fish, seafood, and dairy products also don’t contain oxalates and are excellent options for a low-oxalate diet.
6. What is oxalate?
Oxalate is a naturally occurring compound found in many plant foods. Oxalates can bind to minerals such as calcium, magnesium, and iron, which can cause nutrient deficiencies and increase the risk of kidney stones in oxalate-sensitive individuals.
