Spinach is rich in vitamin C and mineral nutrients, but because it contains more tannic acid, taste bitter. The oxalic acid contained in spinach is an organic acid. It can directly interact with calcium in the human body to form calcium oxalate precipitates. Affects the body's absorption of calcium. If you eat raw, it will cause acute kidney failure.
In addition, oxalic acid can impede the absorption of calcium and cause hypocalcemia. In severe cases, it can jeopardize kidney and liver function. Therefore, when the soup is not used, the spinach can be washed and cut and then directly sprinkled in the soup for consumption, and it cannot be directly cooked and eaten.
The method of cooking is to wash the spinach and put it in a boiling pot for a little time and immediately cool the fish in cool water. This dripping process can remove more than 80% of the oxalic acid in the spinach. Only after such an operation can the food be cooked and eaten, and there is no longer astringency on the taste.
