1, spinach+cucumber. Cucumber contains enzymes that decompose vitamin C, while spinach is rich in vitamin C, so they should not be eaten together. Vitamin C in spinach will be destroyed by decomposing enzymes in cucumber.

2, spinach+pig liver. Spinach should not be fried with pork liver. Pig liver is rich in copper, iron and other metal elements. Once combined with spinach with high vitamin C content, metal ions can easily oxidize vitamin C and lose its nutritional value. Animal liver, egg yolk and soybean are rich in iron, so it is not suitable to eat with amaranth and spinach containing more oxalic acid. Because both cellulose and oxalic acid will affect the absorption of iron in the above foods.

3, spinach+milk. Spinach and other fruits and vegetables containing more oxalic acid will combine with calcium to form insoluble precipitate, which will affect the absorption of calcium in milk.

4, spinach+cheese. Spinach and cheese are very similar. The chemical components contained in cheese will affect the absorption of rich calcium in spinach.
