Cause of disease: If the green beans are not cooked, the saponin in the beans will obviously stimulate the digestive system, and the beans contain coagulation factors, which have the function of coagulation. In addition, green beans also contain nitrates and proteases, which can stimulate the gastrointestinal tract of the body, causing food poisoning and gastroenteritis symptoms.

Prevention: In order to better avoid the poisoning of green beans, the green beans must be cooked thoroughly and thoroughly.

2. Auricularia auricula has harmful endotoxin: phylline luster chemicals.

Cause of disease: Fresh auricularia contains phylline luster chemicals. After eating fresh auricularia directly, it can cause solar dermatitis, and the skin is itchy, swollen and painful in severe cases.

Prevention: You don't have to eat fresh fungus. If you want to eat it, you must cook it thoroughly.

3. Water bamboo is harmful to endotoxin: hydrochloric acid.

Pathogenic reasons: broccoli, bamboo shoots, water bamboo and other vegetables and fruits containing more hydrochloric acid need to be blanched with boiling water to remove most of the hydrochloric acid from the vegetables and fruits, even if they want to be mixed with cold dishes. Oxalic acid will fuse with calcium in the stomach and intestines to form calcium oxalate which is difficult to digest and absorb, which affects the digestion and absorption of calcium in the body and causes calcium deficiency in the human body.

Prevention: Be sure to blanch with boiling water.

4, broad beans have harmful endotoxin: nestin glycoside.

Pathogenic cause: Vicia faba seeds contain nestin glycoside, which can cause subacute hemolytic anemia (Vicia faba yellow disease) after people take this chemical. When eating green broad beans in spring and summer, if cooking is unreasonable, people often get poisoned. And it usually occurs 4 ~ 24 hours after eating raw broad beans.

Prevention: In order to better avoid broad bean poisoning, try not to eat fresh and tender broad beans, and be sure to cook them before taking them.

5, Chrysanthemum morifolium has harmful endotoxin: nitrate.

Pathogenic reasons: Some chemicals contained in wild vegetables such as chrysanthemum morifolium and grey vegetables may be converted into nitrate during cooking operation. If the body takes too much, it may be poisoned.

Prevention: cook before eating, not to mention eating overnight meals.

6, horse teeth are harmful: dust and bugs.

Pathogenic cause: wild vegetables such as horsetooth, which contain dust and bugs, can cause skin allergies. In addition, it is better to peel and clean nest bamboo shoots and water chestnuts before eating them directly, and then blanch them with boiling water before eating them, which is more environmentally healthy and will not harm the taste and nutritional components.

Prevention: blanch the horse teeth with boiling water before eating. It is also best to peel and clean the nest bamboo shoots and water chestnuts before eating them directly, and then blanch them with boiling water before eating them.

7. Broccoli is harmful to endotoxin: phosphate.

Pathogenic cause: Broccoli tends to accumulate phosphate. Nitrate itself has low toxic and side effects on human body, but it will change into nitrate under the action of microbial strains in human body.

Prevention: Take it after it is thoroughly cooked.
