Calcium oxalate is naturally present in a number of different foods and those who have calcium oxalate kidney stones or oxalosis will definitely be able to benefit from them in a very significant way. As far as kidney stones are concerned, calcium oxalate is the most common type. It is important that you have some idea as to which foods are high in oxalate in order to prevent these from forming in the body.
You will find that most nuts including walnuts, pecans, cashews, and almonds are high in oxalates. They contain around 200mg of oxalates for every 100 gram serving, which is a fairly significant amount. Sunflower seeds are another good example of oxalate-rich foods which contain about 100 grams of oxalate per every 100 gram serving.
