What are the dietary recommendations for someone with kidney stones?

Carmen Patrick Mohan, MD
Internal Medicine
If you have recurrent symptoms related to kidney stones, it may be helpful to take a stone to your doctor for chemical analysis. Your urine can also be collected to help determine the primary cause of the stones. There are some dietary changes that may help reduce stone formation because they can help reduce the concentration of calcium and oxalate in the urine:
  1. Increase fluid intake, especially of water.
  2. Drink coffee and/or tea.
  3. Reduce animal proteins and become primarily a vegetarian.
  4. Eat fruits and vegetables with every meal.
  5. Lower your salt ingestion by avoiding processed foods and do not add table salt to flavor food.
  6. Avoid overly sweet foods and all sodas.
  7. Do NOT take vitamin C supplements.
