A person should include foods rich in calcium, especially if they consume many foods that are higher in oxalate, such as spinach. A diet low in calcium increases the risk of developing kidney stones. Calcium and oxalate bind together in the intestines, interrupting the formation of stones.

Some foods to include are:

  • low-fat or fat-free milk products
  • calcium-fortified foods, such as cereals, bread, and juices
  • beans
  • calcium-rich vegetables, such as broccoli
  • seaweed, such as kelp
