1. Spinach + tofu.

Tofu contains magnesium chloride and calcium sulfate, while spinach contains oxalic acid. When these two foods come together, they can produce magnesium oxalate and calcium oxalate. These two white precipitates not only affect the body's absorption of calcium, but also easily lead to stone disease.

2. Spinach + cucumber.

Cucumbers contain 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.

3. Spinach + pork liver.

Pork liver should not be fried with spinach. 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 + milk.

Spinach and other fruits and vegetables that contain a lot of oxalic acid will combine with calcium to form insoluble precipitates, affecting the absorption of calcium in milk.

5. Spinach + eel.

Spinach and eel are incompatible with each other, and eating them together can easily lead to diarrhea. Eel tastes sweet and warm, and has the effects of nourishing qi and blood, strengthening the spleen and kidneys, replenishing qi and solidifying membranes, removing blood stasis and removing dampness; while spinach is sweet, cold and slippery, lowering qi and moistening dryness. "Compendium of Materia Medica" says: "to clear the intestines and stomach" "Hot." It is obvious that the nature, taste and function of the two are incompatible. Moreover, eel is greasy and fatty, and spinach is cold and slippery. Eating them together can easily lead to diarrhea.
