Nutritional Therapy for Kidney Stones
Nutrition therapy is implemented based on an individual's 24-hour urine biochemistry, blood chemistry, stone type and other medical considerations, such as medications and other diseases.
Important note: There is no kidney stone diet that is appropriate for all users.
The following are elements of common nutrition therapy for kidney stones:
  • Fluids
  • Sodium
  • Meat, Poultry, Fish and Seafood
  • Oxalate
  • Calcium
  • Lemonade, Limeade and other Fruit Juices
  • Fruits and Vegetables: Fruits and vegetables, including fruit and vegetable juices, are the only food groups that provide an alkaline load to the body. Adding more alkaline foods to your diet will increase your urine pH (make it less acid) and reduce your risk for certain types of stones. Fruits and vegetables are also good sources of fiber, phytate, magnesium and citric acid (also known as citrate), all of which inhibit the growth of stones by various means.
  • Sugar and Carbohydrates: These contribute to calcium stones. A high intake of carbohydrates, specifically from sucrose (such as in table sugar and foods made with sugar), is associated with hypercalciuria.
