Rice cakes are the ultimate blank-slate snack for kidney stone patients: 1 mg oxalate per cake, about 35 calories each, and infinitely customizable. Top with cream cheese (calcium bonus — actively helpful), avocado slices, or a thin spread of peanut butter in moderation. The plain salted versions add sodium — choose unsalted or lightly salted. Rice cakes have a reputation as boring diet food, but for stone formers they're a practical vehicle for calcium-rich toppings that help offset oxalate from other foods in your day. Keep a package in your pantry for quick snacks.
