In general, spinach cannot be eaten with tofu. Many clinical evidence shows that spinach is sweet and cool in nature, rich in carotene, vitamin C, protein, sugar, calcium, phosphorus, folic acid, oxalic acid, etc. It can help digestion, quench thirst and moisturize the intestines, and can promote pancreatic secretion. Eat spinach, the human body normal vision and epithelial cells are beneficial, and can prevent night blindness, enhance resistance to infectious diseases and promote children's growth and development, etc., on the prevention of inflammation of the corners of the mouth, inflammation of the lips, inflammation of the tongue, dermatitis, scrotal inflammation has a certain effect. And tofu is cold, sweet, with heat diuretic, beneficial to the broad efficacy, but contains more purine.

The theory of Chinese medicine is that cold has the effect of clearing heat and diarrhea, and tofu and spinach two things add up to more cold, hurt the stomach, hurt the spleen, hurt the kidneys. Especially for the ordinary stomach cold for boredom, regurgitation, belching, acid swallowing, or easy to bloating, diarrhea of the spleen, or often have spermatorrhea, premature ejaculation, lumbago, nocturnal urination of the kidney, or after the illness of the body, dizziness, numbness, post-partum weakness, self-sweating, thinning of stools, urination, or patients with gout and increased uric acid concentration should not be consumed.

In addition, spinach has a laxative function, tofu also contains cold medicinal properties of gypsum, spinach and tofu with consumption, easy to cause dilution of stools, severe abdominal pain, diarrhea and other symptoms.

Moreover, tofu contains calcium sulfate, magnesium chloride and other inorganic salts. If you meet with the oxalic acid in spinach, it is synthesized into calcium oxalate and magnesium oxalate, and these two compounds produce a white precipitate, which cannot be absorbed by the human body. Therefore, long-term diet, so that people lack of calcium or stones, especially for children are not favorable.

Now some people mentioned that "spinach in boiling water blanching, and then can be fried with tofu", this statement has some truth. However, further research is needed to prove whether spinach is blanched in boiling water, oxalic acid content will decline, specifically how much will decline, at present, there is no data in this regard
