some vegetables contain toxins. If they are not cooked by heating, their toxins cannot be removed. If they are eaten into the human body, they may have to be cooked. Here are a few vegetables that need to be cooked to eat. Let’s have a look.


harmful substance: linseed bitter glycoside. Pathogenic cause: Although cassava tuber root is rich in starch, all parts of the whole plant, including root, stem and leaf, contain toxic substances, and fresh tuber root is more toxic. Therefore, we must pay attention to when eating cassava root tubers. The toxic substance contained in cassava is linolenic Picroside. If you take raw or uncooked cassava or drink its soup, it may cause poisoning. The reason is that the free hydrocyanic acid is produced by the hydrolysis of linseed Picroside or linseed picrosidase by gastric acid, which makes the human body poisoned. If a person eats 150-300 grams of raw cassava, it can cause poisoning or even death. Detoxification method: to prevent cassava poisoning, peel cassava before eating, soak the meat with water to dissolve cyanoside. Generally, 70% of cyanoside can be removed after soaking for about 6 days, and then it can be cooked and eaten.

broad bean

harmful substance: chaocaioside. Cause of disease: the seeds of broad bean contain nestinin, which can cause acute hemolytic anemia (broad bean yellow disease). When eating green broad bean in spring and summer, if it is not cooked properly, it will often lead to poisoning. And generally in 4 ~ 24 hours after eating raw broad bean disease. Detoxification method: in order to prevent the occurrence of broad bean poisoning, it is best not to eat fresh broad bean, and must be cooked before eating.

kidney bean

harmful substance: saponin. Cause of disease: if the kidney beans are not cooked, the saponin in the beans will strongly stimulate the digestive tract, and the beans contain coagulant, which has the effect of coagulation. In addition, kidney beans also contain nitrite and trypsin, which can stimulate the body’s intestines and stomach, causing food poisoning and gastroenteritis. Detoxification method: in order to prevent kidney bean poisoning, it is necessary to boil the kidney bean thoroughly.

water bamboo

harmful substance: oxalic acid. Cause of disease: spinach, bamboo shoots, water bamboo and other vegetables with more oxalic acid, even if they need to be cold, they should be blanched with boiling water to remove most of the oxalic acid contained in vegetables. Oxalic acid will combine with calcium in the intestine to form calcium oxalate which is difficult to be absorbed. It interferes with the absorption of calcium and leads to calcium deficiency in the body. Detoxification method: be sure to blanch with boiling water.

Auricularia auricula

harmful substances: phylline light sensitive substances. Cause of disease: fresh Auricularia contains phylline light sensitive substances. After eating raw Auricularia, it can cause solar dermatitis, and in severe cases, it can cause skin itching, edema and pain. Detoxification method: do not eat fresh Auricularia auricula, to eat, must be cooked, cooked thoroughly to eat.


harmful substance: colchicine. Cause of disease: there is a kind of colchicine in fresh day lily, colchicine is non-toxic, but after absorption by gastrointestinal tract, it will be oxidized to form highly toxic colchicine, which can stimulate intestines and stomach, resulting in dry throat, heartburn, thirst, abdominal pain, diarrhea and other symptoms. Detoxification method: because colchicine is water-soluble, in the cooking and drying process of fresh day lily, this kind of alkaloid has been destroyed. In addition, when eating day lily dry products, it must be soaked in water. Of course, there is no danger of poisoning.


harmful substance: nitrate. Cause: spinach, mustard and other vegetables are easy to accumulate nitrate. Nitrate itself has low toxicity to human body, but it will be transformed into nitrite under the action of microorganisms in human body. Detoxification method: can not eat raw, must be thoroughly cooked before eating. So, you can eat the soup once it’s gone; Instant boiled mutton & quot; It’s not advisable to eat in the same way.
