Some foods rich in oxalates of vegetable origin are spinach, beet, okra or cocoa powder, for example.
Oxalates are substances found in some foods that facilitate the formation of kidney stone. Therefore, avoiding foods rich in oxalates is important to prevent the appearance of kidney stone, which causes symptoms such as severe back pain and pain when urinating, for example.
Table of foods rich in oxalates
| Foods | Quantity of oxalates in 100 g of food |

Oxalic acid or oxalate, in addition to facilitating the formation of kidney stone, also impairs the absorption of many nutrients by the body. Therefore, the foods mentioned in the table should not be ingested in large quantities.
How to reduce diet oxalates
To decrease the amount of oxalate without excluding these foods from the diet it is important to only consume them after scalding them with boiling water and dispense the first cooking water, which is very important to do mainly with spinach as it is very rich in oxalates .
This is because oxalate-rich vegetables should not be completely excluded from food, as they are also rich in iron and other important nutrients for a balanced diet.
A kidney stone feed, for example, should have a low daily intake of oxalates, which should not exceed 40 to 50 mg / day, which corresponds to not eating more than one tablespoon of beet per day, for example.
