First, fresh auricularia auricula contains a light-sensitive substance, which will be distributed to human epidermal cells with blood circulation after being eaten by people. After being irradiated by the sun, it will cause solar dermatitis. This toxic light-sensitive substance is also easily absorbed by the throat mucosa, leading to edema of the throat. Second, fresh day lily is also known as day lily. Fresh day lily contains toxic substance colchicine. After this substance enters the human body, it will make people dry throat, thirsty, burning sensation in the stomach, nausea, vomiting, abdominal pain and diarrhea. Third, green tomatoes Immature tomatoes contain alkaloids, which can cause poisoning after people eat them. Fourth, germinated potatoes germinated potatoes will produce a lot of solanine, which will be poisoned after people eat it. When using germinated potatoes, the buds and roots and the green part of the potato skin should be dug up and soaked in clear water for more than 2 hours. 5. Fresh broad beans Some people lack certain enzymes, which will cause allergic hemolysis syndrome after eating fresh broad beans. Symptoms are general fatigue, anemia, jaundice, hepatomegaly, vomiting, fever, etc. If not rescued in time, it will die of extreme anemia. 6. Unproked green beans Unproked green beans contain saponins, which will be poisoned after people eat them. Fried green beans are non-toxic. Seven, rotten ginger rotten ginger will produce a carcinogen called safrole, which can induce liver cancer and esophageal cancer. Eight, rotten vegetables under the action of strong bacteria, nitrate in rotten vegetables is reduced to nitrite. After this substance enters the human body, it can make the blood lose the function of carrying oxygen, resulting in hypoxia, causing headaches, dizziness, nausea, vomiting, rapid heartbeat, cramps and other symptoms. Nine, fresh lentils Fresh lentils contain saponins and alkaloids, which are toxic, but will dissolve when heated. Blanch with boiling water or oil before eating, or dry until it becomes discolored before eating. 10. Deteriorated white fungus Rotten white fungus will produce a large number of Flavobacterium Fermented Rice, which will cause discomfort in the stomach after eating, and in severe cases, toxic shock may occur. Second, several foods: 1, green beans If the green beans are not cooked, the saponin in the beans will strongly stimulate the digestive tract, and the beans contain thrombin, which has a clotting effect. In addition, green beans also contain nitrite and trypsin, which can stimulate the human stomach and make people suffer from food poisoning and gastroenteritis. 2. Broad bean Broad bean seeds contain nestin glycoside, which can cause acute hemolytic anemia (broad bean yellow disease) after people eat this substance. When eating green broad beans in spring and summer, if it is not cooked properly, it will often cause poisoning. It is best not to eat fresh tender broad beans, and it must be cooked before eating. 3, raw soybean milk Because raw soybeans also contain toxic ingredients, if soybean milk is eaten when it is not cooked, it can also cause food poisoning. Especially when soybean milk is heated to about 80℃, saponin expands when heated, and the foam floats up, forming a "false boiling" phenomenon. In fact, the toxic components such as saponin in soybean milk are not completely destroyed at this time. If you drink this soybean milk, it will cause poisoning, usually after eating 0.5~ 1 hour, you will get sick, mainly with gastroenteritis symptoms. Cooked soybean milk has no foam, and the disappearing foam also indicates that toxic components such as saponin are destroyed, and then it is cooked with low fire for about 10 minutes. 4. Cassava Although the root tuber of cassava is rich in starch, all parts of the whole plant, including roots, stems and leaves, contain the toxic substance flaxseed picroside. If you ingest raw or uncooked cassava or drink its soup, it may cause poisoning. The reason is that flaxseed picroside or flaxseed picrosidase produces free hydrocyanic acid after gastric acid hydrolysis, which makes people poisoned. Deteriorated rice and peanuts, which contain aflatoxin, are carcinogens and are prohibited.
