1. Green vegetables generally cannot be eaten with cucumbers, rabbit meat, seafood, vinegar and calcium-containing foods.

2. Cucumber: Green vegetables cannot be eaten together with cucumbers, because cucumbers contain vitamin C-degrading enzymes that will destroy the vitamin C in green vegetables. The more vitamin C there is in the food, the more serious it will be destroyed by the decomposing enzymes in cucumber.

3. Rabbit meat: Vegetables cannot be eaten together with rabbit meat, because rabbit meat is cold in nature and conflicts with vegetables, which can easily cause diarrhea, vomiting and other uncomfortable symptoms in patients.

4. Seafood: Green vegetables cannot be eaten with seafood. Because seafood and too much vitamin C can be toxic. The valence of arsenic in shrimp is pentavalent. Generally, pentavalent arsenic is harmless to humans. However, if a large dose of vitamin C and pentavalent arsenic are ingested and undergo complex chemical reactions, they will be converted into toxic trivalent arsenic. When the trivalent arsenic reaches a certain dose, it will cause human poisoning. Other symptoms such as vomiting, dizziness, nausea, and abdominal pain may occur.

5. Vinegar: When cooking vegetables, if acidic seasonings are added, their nutritional value will be reduced. Because the chlorophyll in green vegetables is extremely unstable when heated under acidic conditions. The magnesium ions in its molecules can be replaced by oxygen ions in the acid to produce a dull olive pheophytin, which greatly reduces the nutritional value. Therefore, patients are advised to stir-fry green vegetables quickly under neutral conditions over high heat. This can not only maintain the bright green color of vegetables, but also reduce the loss of nutrients.

6. Calcium-containing foods: Do not eat vegetables with calcium-containing foods, such as tofu. There is oxalic acid in green vegetables, which will combine with the calcium in tofu to form calcium oxalate, which is difficult for the human body to absorb and may cause stones over time. Moreover, eating it this way will destroy the nutrients.
