Practical next steps for hydration, oxalate, and reducing the chance of another.
Why food lists are not enough
A printed "high-oxalate foods" list tells you what to avoid. It doesn't tell you whether the spinach you ate at lunch already used your entire daily budget.
StoneStop turns oxalate into a number you can see. Add what you eat. Watch the total. Decide what's safe for dinner.
Be mindful at dinner.

Frequently asked questions
How much oxalate should I eat per day?
A common guideline for people on a low-oxalate diet is to stay under about 100 mg per day, but the right target depends on your stone type and your clinician's plan. StoneStop defaults to a 100 mg daily target you can adjust in settings.
Is StoneStop medical advice?
No. StoneStop is an educational tracking tool. It helps you log oxalate and water between appointments. Always follow guidance from your urologist, nephrologist, or registered dietitian for diagnosis or treatment.
Do I need to know my stone type to use it?
You can start logging without it, but the right oxalate target depends on whether you form calcium oxalate stones. If you don't know your stone type, ask your clinician — they can confirm whether a low-oxalate diet applies to you.
Where do the oxalate values come from?
StoneStop's food values are sourced from the Harvard T.H. Chan School of Public Health and the University of California Irvine Kidney Stone Center. Values vary by source, preparation, and portion. See the Sources page for more.
Does drinking water help with kidney stone prevention?
Most kidney stone prevention plans include staying well hydrated to keep urine dilute. StoneStop helps you track daily water intake alongside oxalate. It is not a treatment — talk to your clinician about a hydration target that's right for you.
