Spinach should not be eaten with the following foods:
Spinach is rich in oxalic acid, and tofu is rich in magnesium chloride and calcium sulfate. When these elements are combined, magnesium oxalate and calcium oxalate will be produced. However, these substances are not absorbed by the human body, so the body can not get nutrition, and it will also cause stones.
Cucumber contains a substance called vitamin C decomposing enzyme, which will decompose vitamin C, making it impossible for human body to absorb vitamin C, and vitamin C in spinach will also be decomposed by it, so it has no nutritional value at all.
The most abundant elements in pig liver are iron and copper, but when they meet vitamin C, they will decompose vitamins, so the value of vitamins does not exist. Animals' livers, egg yolks, soybeans and other things are rich in iron. Avoid eating them with things rich in oxalic acid, because it will hinder the absorption of calcium.
The most abundant element in milk is calcium, and oxalic acid in spinach can't meet calcium, which will reduce the nutritional value of milk. Similarly, the calcium in cheese is also very rich, which will affect the absorption of calcium by human body.
Spinach can moisten the lungs because spinach is cold, while eel is warm, which conflicts. If eaten together, it will lead to diarrhea and gastrointestinal discomfort. Therefore, we should avoid eating them together.
Oxalic acid in leeks is also extremely huge, and so is spinach. Eating both together is not conducive to the body's absorption of nutrients. More importantly, both of them are cold and easy to have diarrhea.
Needless to say, calcium in calcium tablets is very rich, but once spinach is encountered, its nutritional value will be greatly reduced, so both should be avoided.
