What's the difference between 'Low' and 'Safe'?
Low Oxalate means under 25 mg per serving — the same threshold as Safe. They're equivalent in practice. The verdict system uses Low/Moderate/High to describe oxalate categories and Safe/Caution/Avoid to recommend dietary action.
Can oxalate levels change with cooking?
Yes. Boiling and discarding water can reduce soluble oxalate by 30-50% in many vegetables. Check the food's main page or cooking-specific angle page for details on preparation effects.
Is 'Low Oxalate' the same as 'No Oxalate'?
No — almost all plant foods contain some oxalate. 'Low Oxalate' means under 25 mg per serving, which is considered safe for kidney stone patients. Only purified products like sugar, oil, and salt have near-zero oxalate.
