What's a Safe Portion Size of Juice?

A standard serving of Juice is 1 cup (27 mg oxalate). For kidney stone patients, a half serving (13 mg) is more manageable. Think of Juice as a side dish or flavor accent, not the main component of your meal. The NKF recommends keeping daily oxalate under 100 mg total — so 27 mg from one food is significant, while 13 mg leaves more room for other foods.

❓ Related Questions

How do I track oxalate across a whole day?

Add up the oxalate from each food you eat. Aim for under 100 mg total for the day as a general reference. Spread oxalate across meals rather than concentrating it in one. Drink plenty of water to keep urine dilute.

What if I accidentally eat a large portion?

Don't panic — one high-oxalate meal doesn't immediately cause a stone. Drink extra water for the next 12-24 hours to dilute your urine. Return to your normal careful portions at the next meal.

How do I know if my portions are right?

If you consistently produce pale yellow urine, drink plenty of water, and spread oxalate across meals rather than concentrating it, you're likely in good shape. Track oxalate for a few days to get a sense of your typical intake.
