Best foods to eat for oxalate calcium diet?

Low oxalate: Calcium oxalate stone formers are often advised to eat a low oxalate diet. Many foods contain higher levels of oxalate, including (but not limited to) dark leafy greens, nuts, dark chocolate, black tea, and beans. The less oxalate one eats, the less will be excreted into the urine to pair with calcium ions and crystallize into stones. Most stone patients do not need to limit their calcium intake.

Re: kidney stones: You want a low oxalate diet. Calcium does not usually require restriction. Oxalate is found in spinach, cola, nuts, chocolate, beets, tea, cranberries, and rhubarb. Avoid these.
