Spinach can't be eaten at night. You can eat spinach in moderation at night, but eating too much is not good. If you really want to eat spinach at night, you'd better blanch it in boiling water first, and then clean the oxalic acid inside. If you don't cook it, the calcium oxalate inside is easy to get stones.

In addition, pregnant women should not eat spinach. Zinc and calcium are indispensable trace elements for human body. If the human body is short of zinc, people will feel poor appetite and taste. If pregnant women eat too much spinach, it will undoubtedly be detrimental to fetal development.

Precautions:

Spinach and tofu can't be eaten Spinach contains a lot of oxalic acid, and tofu mainly contains protein, fat and calcium. They are cooked in the same pot, and oxalic acid can react with calcium to form insoluble precipitate, which cannot be absorbed by human body. You can blanch spinach first, let some oxalic acid dissolve in water, take it out and cook it with tofu.

Spinach should not be eaten with cucumber and Chinese cabbage. Cucumber contains vitamin C decomposing enzyme, which will destroy vitamin C in spinach and reduce its nutritional value.
