Frequently Asked Questions

  • Is it possible to reduce the risk of calcium oxalate stones?

    There are a variety of diets that can prevent different types of kidney stones. The National Institutes of Health states that the Dietary Approach to Stop Hypertension (DASH) diet may reduce the risk of kidney stones. Here are some basic guidelines:

    • Drink plenty of water (and other fluids).
    • Limit caffeinated beverages.
    • Reduce salt intake in your diet.
    • Limit animal protein intake.
    • Eliminate refined sugar and high fructose corn syrup.
    • Men should avoid vitamin C supplements.

    To prevent oxalate stones, limit fruit juice concentrates, beets, spinach, rhubarb, tea, dark green vegetables, beer, and chocolate (these are all foods high in oxalate).

    When eating oxalate-rich foods, eat or drink calcium-rich foods. When oxalate and calcium combine in the stomach, oxalate stones are less likely to form.

  • What should I eat to reduce my risk of uric acid stones?

    To prevent uric acid kidney stones, reduce the amount of meat, eggs, fish and poultry you eat. Try to get more of your daily protein from plant sources.

  • Why does animal-derived protein increase the risk of kidney stones?

    Eating too much animal protein can increase uric acid levels and lower citrate in the urine. Citrate is a chemical that helps prevent kidney stones from developing.
