❓ Frequently Asked Questions

Can I eat Juice with kidney stones?

Straight talk: Juice is high in oxalate. 1990 mg per 1 cup puts it firmly in the avoid zone (100+ mg). Kidney stone patients should limit this one. Harvard measured it, not us.

What's the oxalate content of Juice?

The exact figure: 1990 mg of oxalate per 1 cup of Juice. Works out to 829 mg/100g. This is the number kidney stone patients actually need. Harvard (2024) verified.

Is Juice low or high oxalate?

Yeah, it's high. 1990 mg per 1 cup is way over the safe threshold. Juice belongs in the 'limit severely' column.

What are the best low-oxalate alternatives to Juice?

Look at the 'Safe Alternatives' section right below this FAQ. Those foods are all under 25 mg oxalate per serving and in the same category as Juice. Pick from those.

Is Juice a good drink for kidney stones?

As far as kidney stones go, Juice is in the avoid zone for beverages at 1990 mg per serving. Hydration matters more than anything — so drink plenty of water regardless of what else you consume.

Does boiling Juice reduce the oxalate?

Yes — boiling Juice and dumping the water can cut oxalate by roughly 30-50%. The oxalate dissolves into the water, and you pour it out. Steaming does way less. Raw = max oxalate.

How much sodium does Juice have?

Sodium's not the issue here. Juice has 10 mg per 100g — comfortably low. No need to worry about salt pushing extra calcium into your urine with this food.
