Numerous studies have shown that those who have a high amount of oxalate in their urine are more likely to develop oxalate stones which are quite similar to that of kidney stones and can do a lot of damage in the body over time. Certain people should limit the amount of foods they eat which are high in oxalates, simply so they will be able to avoid this particular problem in the future.

Although spinach as well as many other vegetables like cauliflower, cucumber, peas, and chives contain lots of healthy vitamins and minerals, they are also high in oxalates. Spinach and asparagus are especially high in oxalates which is precisely why you will want to limit how much you eat on a regular basis, especially if you are already likely to develop problems with oxalate stones.
