📦 Processed Food
Canned, packaged, or processed foods. Based on Harvard T.H. Chan SPH oxalate data (2024).
48 foods in this collection
Processed and packaged foods carry a double risk for stone patients: sodium added during manufacturing raises urinary calcium, and some processed items (crackers, baked goods, flavored products) land higher on the oxalate table than their base ingredients. The label is the tool — check the sodium line first, then look up the specific product's oxalate value. Rinsing canned beans, choosing no-added-salt versions, and seasoning at home rather than relying on packaged sauces are the practical levers.
