1. Spinach and tofu cannot be eaten together

When eating spinach and tofu, some people cook them in one pot and think it is the most ideal vegetarian food. But this is a wrong approach. Because spinach contains chlorophyll, iron, etc., it also contains a large amount of oxalic acid. Tofu mainly contains protein, fat and calcium. Cooking the two in one pot will waste precious calcium. Because oxalic acid can react chemically with calcium to form an insoluble precipitate that cannot be absorbed by the human body. Therefore, in order to maintain nutrition, one is to divide spinach and tofu into separate meals so that there will be no chemical reaction. Second, you can blanch the spinach in water first to let part of the oxalic acid dissolve in the water, then take it out and cook it with tofu.

2. Spinach and eel cannot be eaten together

The medicinal properties of eel are sweet and warm, which can replenish qi and relieve cold air in the abdomen. Spinach is sweet, cold and slippery in nature, and can lower qi and moisturize dryness. According to the "Compendium of Materia Medica", spinach can "relieve gastrointestinal heat". It can be seen that the taste, taste and functions of the two food medicinal properties are not coordinated. Moreover, fried eel is fatty and spinach is cold and slippery. Eating them together can easily lead to diarrhea, so they should not be eaten together.

3. Spinach and pork liver cannot be eaten together

Spinach should not be fried with pork liver. Pork liver is rich in copper, iron and other metal elements. Once combined with spinach, which contains high vitamin C, the metal ions can easily oxidize vitamin C and lose its nutritional value. Animal livers, egg yolks, and soybeans are rich in iron and should not be eaten with amaranth and spinach, which contain a lot of oxalic acid. Because both fiber and oxalic acid will affect the body's absorption of iron in the above foods.

4. Spinach and cucumber cannot be eaten together

Cucumber contains vitamin C-degrading enzymes, while spinach is rich in vitamin C, so they should not be eaten together. The vitamin C in spinach is destroyed by the catabolic enzymes in cucumber.
