❓ Frequently Asked Questions
How does animal protein affect kidney stones?
Excess animal protein can increase uric acid and calcium in urine, while decreasing citrate (a stone inhibitor). The AUA recommends moderation — about 3 oz (palm-sized) per meal.
What counts as 'moderate' animal protein?
A deck-of-cards-sized portion (3 oz) per meal is the general reference. Plant proteins like tofu, lentils, and beans are good alternatives that don't carry the same risk.
Can I eat animal protein at all with kidney stones?
Yes — the recommendation is moderation, not elimination. Small portions of lean animal protein as part of a balanced diet are generally fine.
This is dietary reference information, NOT medical advice. Talk to your doctor or a registered dietitian before changing your diet. Oxalate tolerance varies by person, stone type, and medication.
