let’s look at how to cook different kinds of vegetables!

1. Legume vegetables: there is a toxic protein, called hemagglutinin, which can agglutinate red blood cells in the seeds of soybean vegetables such as soybean, broad bean, kidney bean, lentil and potato tubers. When eating these vegetables that are not thoroughly cooked, they often cause nausea, vomiting and other symptoms, which can be fatal in severe cases. These vegetables also contain a kind of antitrypsin with the nature of toxic protein. Its toxicity is to inhibit the activity of protease and cause pancreatic enlargement. The seeds (and pollen) of broad bean contain a kind of nest glycoside called faba bean toxin, which can destroy red blood cells. When eating hard boiled broad beans, it will induce hemolytic anemia, which is known as “broad bean disease”. Suggestion: the toxic substances contained in legume vegetables will lose their activity after heating, so they must be fried and boiled thoroughly before eating.

2. Potato vegetables: the reason why potato vegetables are not suitable for raw food is that they contain toxic glycosides. The root tubers of cassava with high starch content contain cyanogen glycosides, which will lead to cyanogen acidosis after being cooked without soaking. As for solanine (solanine) in potato tubers, the content of solanine (solanine) is very high in the light green cortex (10 times higher than that of normal tubers), which will not be damaged even after being cooked and can not be eaten at all. Vegetables containing more oxalic acid: spinach, bamboo shoots, Zizania latifolia and other vegetables with more oxalic acid should be blanched with boiling water to remove most of the oxalic acid in vegetables even if they are to be cold mixed. Oxalic acid will combine with calcium in the intestine to synthesize calcium oxalate which is difficult to be absorbed, which interferes with the absorption of calcium by human body and leads to calcium deficiency in the body.
