2. Chocolate
This is a favorite sweet treat to many people, but this is something that you should give up if you suffer from kidney stones, as this too is a concentrated source of oxalate. Depending on the amount of cocoa used in a chocolate bar, the oxalate level may vary. The higher the cocoa content is, the higher the oxalate level is. For instance, chocolate bars that contain 76% cocoa contain 250 milligrams for every 3.5 ounces. The oxalate level will be almost twice for chocolate bars containing 100% cocoa.
3. Spinach
Spinach is a known power food as it contains various nutrients. Plus, it’s also affordable. This leafy green vegetable is high in fiber, calcium, iron, folate, and vitamins B6, K, C, and A. It is also rich in antioxidants. However, it contains high amount of oxalate so it should be avoided if you are under a low oxalate diet. Ever 3.5 ounces of spinach contains 750 to 800 milligrams of oxalate.
