❓ Frequently Asked Questions

Can I eat Juice with kidney stones?

Yep, you're good. Juice clocks in at 3 mg oxalate per 1 cup — way under the 25 mg cutoff. Eat it without the stress. Measured by Harvard, not guessed.

How much oxalate is in Juice?

Quick math: 1 cup of Juice = 3 mg oxalate. 100g = 1 mg. Both numbers come from Harvard's latest lab measurements. Not AI, not a database, actual lab work.

Is Juice high in oxalates?

Low. 3 mg per 1 cup puts Juice firmly in the low-oxalate category. Safe for regular eating if you're managing kidney stones.

What can I eat instead of Juice?

Substitutes exist. The safe alternatives listed below are all low-oxalate foods in the same family as Juice. Grab one of those and you dodge the oxalate while keeping similar flavors.

How much sodium does Juice have?

Low sodium: 10 mg/100g. That's a non-issue for kidney stones. Just don't undo it by drowning it in salt during cooking.

Is Juice a good drink for kidney stones?

For beverages, 3 mg oxalate per serving puts Juice in the safe category. Most of your daily fluids should still be water. This one's an occasional drink, not your hydration strategy.
