What foods affect my risk of developing kidney stones?

There are no global must-avoid foods, although sugary things tend to be bad for everything, including kidney stones.

Nutrition & Dietetics
A tailored nutrition assessment that compliments medical care is most beneficial in the prevention of kidney stone formation. Dietary interventions should include:
  • Increased fluid intake (approximately three liters with half coming from water).
  • Limiting calcium intake between 800 - 1,000 mg/day, unless pregnant or breastfeeding.
  • Limiting high-oxalate containing foods such as spinach, beets, nuts, chocolate, strawberries, beans/legumes and vitamin C in excess of the RDA (75 mg/day for female, 90 mg/day for male).
  • A reduction in grapefruit juice intake.
  • Moderate intake of protein (0.8-1.0 grams per kilogram of body weight).
  • Substituting vegetable protein intake in place of animal protein, periodically.
  • Reduction in sodium intake.
Some low-oxalate foods include:
  • Veggies: Squash, cabbage, red pepper, cauliflower, cucumbers, iceberg lettuce, water chestnuts and turnips.
  • Fruit: Apples, lemons, cherries, melons, nectarines and mango.
  • Grains: Wild and white rice, cornflakes, egg noodles and rye bread.
  • Meat: Beef, lamb, pork, fish, poultry and shellfish.
  • Drinks: Cola, ginger-ale, cider, milk and water.
