Cooking oils are universally oxalate-free. Olive oil, like all refined oils, contains zero oxalate. Use it for sautéing, roasting, dressings, and marinades without any kidney stone concern. Extra virgin olive oil adds polyphenols with potential anti-inflammatory benefits. The only watchpoint with oils is calories (120 per tablespoon), which matters for weight management — obesity is a kidney stone risk factor. But from an oxalate perspective, olive oil is completely safe.
