1 If you tend to form calcium oxalate stones, your doctor may recommend restricting foods rich in oxalates. 2  These include rhubarb, beets, okra, spinach, Swiss chard, sweet potatoes, nuts, tea, chocolate and soy products.

In fact, eating moderate amounts of dairy products and other calcium-rich foods may lower the risk of forming new stones. This does not apply to calcium supplements, which have been linked to kidney stones in some people.
