cassava

harmful substances: linseed bitter glycoside

pathogenic cause: Although cassava tuber root is rich in starch, but its whole plant parts, 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 the cassava before eating and 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.

kidney beans

harmful substances: 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.
