Frequently Asked Questions

To prevent kidney stones, it’s important to include foods in your diet that can help reduce the risk of stone formation. Here are some of the best foods to incorporate into your diet:

  1. Water: Staying well-hydrated is one of the most critical factors in preventing kidney stones. Drinking plenty of water helps dilute urine and reduce the concentration of minerals that can form crystals and stones.

  2. Citrus Fruits: Citrus fruits like lemons, oranges, and limes are high in citrate, a compound that can help prevent stone formation. Citrate binds to calcium in the urine, making it less likely to crystallize into stones.

  3. Calcium-Rich Foods: Contrary to a common misconception, getting enough calcium from dietary sources is essential for kidney stone prevention. Calcium can bind with oxalate in the digestive tract, reducing the amount of oxalate that reaches the kidneys. Good sources of dietary calcium include low-fat dairy products, tofu, and leafy green vegetables.

  4. Low-Oxalate Foods: If you are prone to calcium oxalate stones, it’s a good idea to moderate your intake of high-oxalate foods. These include spinach, beets, rhubarb, nuts, and certain grains. Instead, choose low-oxalate alternatives like kale, cauliflower, and rice.

  5. Whole Grains: Whole grains like oats, quinoa, and brown rice are nutritious choices that are lower in oxalates compared to refined grains.
