Kidney stone formation can be prevented by following specific diet charts.

Dietary measures to prevent the risk of stone formation are listed below:

  • Drink sufficient water/juices to excrete more than 1.5-2 liters of urine per day.
  • Reduce consumption of protein food to a judicious level, as diet high in protein (e.g., meat fish, pulses, nuts and eggs) may lead to kidney stones.
  • Decrease the consumption of sugar (e.g., sucrose)as sugar also promotes stone formation.
  • Consume adequate amount of calcium every day. You can get enough calcium from food items like milk (120mg/100g), yogurt (120 mg/100g) and cheese (700mg/100g) reducing calcium intake may not decrease risk of stone formation but can lead to osteopenia. Moreover, reduced calcium consumption increases oxalate stone formation.
  • Daily consume raw fruits such as melons, papaya, grapes, bananas, etc. in large quantity as they provide water soluble fiber.
  • Be active and exercise regularly to lose your weight, which may be helpful to flush out better and maintain healthy functioning kidneys.


  • Avoid drinking a lot of coffee/tea and alcoholic beverages.
  • Avoid too much drinking of carbonated drinks, sports drinks and sodas etc.
  • Avoid highly salted (e.g., canned food, ready to eat food snacks, etc.) or sugared foods. High salt intake increases the level of calcium in urine and hence increases the risk of stone formation. This risk increases with the combination of high salt and high protein foods.
  • Avoid oxalate containing foods including nuts, black tea, green leafy vegetables, soya and chocolates.
