Why Oxalate Levels Are Important

Oxalates are chemicals that exist naturally in many foods. They are not dangerous for most individuals. However, among those prone to kidney stones, high-oxalate diets may increase the chance of stone formation. It’s easy to get overwhelmed trying to keep track of which foods are safe—and which to limit. That’s the purpose of OxalateWatch.

What is so special about the OxalateWatch database?

Extensive List: Well over 1,200 foods are covered, significantly more than you would find in most lists.

Lab Measured Data: The database is based on oxalate levels from Harvard (update 2024) and paired with USDA nutrition data.

Searchable & Free No sign up, no paywall. Enter a food and see its oxalate content instantaneously.

Using the Database to Prevent Kidney Stones

Pick low oxalate foods for unlimited freedom (think eggs, dairy, most meats & many fruits).

Identify high-oxalate foods (such as spinach, almonds, beets) and plan portions or substitutes.

Keep your diet balanced and nutritious – and know it! Use USDA nutrition info.

Questions Frequently Asked

Does this database work for all types of stones?

It is specifically designed to avoid oxalate (calcium oxalate) stones, which are the most prevalent form. Ask your doctor for individualized guidance.

How good is the data?

Values are taken from the latest Harvard and USDA sources, however because foods vary naturally, the statistics may vary too. Use the facts as a guide, not a rule.

Not by any means! Moderation and variety are crucial and combining higher oxalate diets with calcium-rich foods can occasionally be helpful for reducing stone risk.
