10 kinds of food must be cooked to eat

Raw Soybean Milk Lethal Toxin: Saponin-induced mechanism

Because raw soybeans also contain toxic ingredients, it can cause food poisoning if the soybean milk is consumed when it is not cooked. In particular, when soymilk is heated to about 80°C, the saponin heat expands and the foam floats, forming a "false boiling" phenomenon. In fact, the toxic components such as saponin present in soybean milk are not completely destroyed. That will cause poisoning, usually after consumption of 0.5 to 1 hour to the onset, mainly gastrointestinal symptoms.

Lettuce Deadly Toxin: Deadly Mechanism of Colchicine

Day lily, also known as day lily, is one of the favorite dishes. However, day lily contains colchicine. If the human body ingests colchicine, it will be oxidized in the body tissue to form two colchicines. The second colchicine is a highly toxic substance that can poison the human gastrointestinal tract and urinary system and poses a serious threat to health. An adult can cause poisoning if he eats 50 to 100 grams of fresh daylily.

Fresh fungus lethal toxin: morpholine photosensitivity lethal mechanism

Fresh fungus contains a kind of ray sensitive material, which is sensitive to light. After eating, it irradiates the sun and causes daylight dermatitis. Some severe cases also cause difficulty breathing due to pharyngeal edema.

Vibrio bean lethal toxin: the causal mechanism of killing

Vicia faba seeds contain nasoside glycosides, which can cause acute hemolytic anemia (faba bean yellow disease). When eating green beans in spring and summer, poisoning may occur if cooking is improper. And it usually occurs after 4 to 24 hours after eating raw beans.

Germinating Potato Lethal Toxins: Deadly Mechanism of Solanine

Potato is one of the vegetables that are often eaten on the family table, but it contains the toxic ingredient solanine (potatotoxin, solanine). The whole potato contains this toxin, but the contents of different parts are different, and the content of mature potato is less. Generally it does not cause poisoning, while the outer skin of potato shoots, flowers, leaves and tubers contains higher solanine, and the toxins of potato shoots are even tens to hundreds of times higher than the meat parts.

Fatal Toxins in Cruciferous Vegetables: Deadly Mechanism of Mustard Oil

Cruciferous vegetables include rapeseed, mustard, radish, etc. Most of these vegetables contain glucosinolates, a toxin that prevents human growth and goitre. Different vegetables, or different parts of the same vegetable contain different glucosinolate content. If not handled properly, it may cause people to have goiter, metabolic disorders, symptoms of poisoning, and even death.

Cassava Deadly Toxin: Fatal Mechanism of Flaminoids

Although the roots of cassava are rich in starch, all parts of the whole plant, including roots, stems and leaves, contain toxic substances, and fresh roots are more toxic. Therefore, care must be taken when eating cassava roots. The toxic substance contained in cassava is linamarin, which can cause poisoning if raw or uncooked cassava is consumed or if it is consumed. The reason is that flavincilin or linaridinease is hydrolyzed by gastric acid to produce free hydrocyanic acid, thereby poisoning the human body.

Lettuce toxin from leeks: nitrite lethal mechanism

Wild vegetables, such as leeks and grey vegetables, contain plenty of nitrite. If the human body ingests excessive nitrite, normal human hemoglobin can be oxidized into methemoglobin, and in addition, nitrite can also prevent oxygenated hemoglobin from releasing oxygen, thereby causing hypoxia in the tissue and causing poisoning.

Seasonal bean deadly toxin: saponin lethal mechanism

If the green beans are not cooked, the saponin in the beans will strongly stimulate the digestive tract, and the beans contain prothrombin, which has a coagulation effect. In addition, green beans also contain nitrite and trypsin, which can stimulate the body's stomach, causing food poisoning and gastrointestinal symptoms.
