Spinach taboo:

Spinach and tofu. Tofu contains magnesium chloride and calcium sulfate, and spinach contains oxalic acid. When two kinds of food meet, magnesium oxalate and calcium oxalate can be produced. These two kinds of white sediments not only affect the absorption of calcium by human body, but also easily lead to lithiasis.

Spinach and 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.

Spinach+pork 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.
