Vegetables are the best sacred products for people to nourish their bodies, but in daily life, you must pay attention to eating vegetables. Because some vegetables contain toxins, if they are not cooked by heating, their toxins cannot be removed. If they are eaten into the body, they will naturally get sick.

1 green beans
Deadly toxin: saponin

Fatal reason: 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 blood coagulation effect.

In addition, the green beans also contain nitrite and trypsin, which can stimulate the stomach of the human body, causing food poisoning and gastrointestinal symptoms.

Detoxification method: In order to prevent the poisoning of green beans, be sure to cook and cook the green beans.

2 fungus
Deadly toxin: porphyrin light-sensitive substance

Fatal reason: Fresh fungus contains porphyrin light-sensitive substances. After eating fresh fungus, it can cause solar dermatitis. In severe cases, itching, edema and pain.

Detoxification method: Do not eat fresh fungus, you must eat it and cook it thoroughly.

3 cassava
Deadly toxin: linsein

Fatal reason: The toxic substance contained in cassava is linseed, and if it is ingested raw or undercooked cassava or drink it, it may cause poisoning.

The reason is that linsein or linsein is hydrolyzed by gastric acid to produce free hydrocyanic acid, thereby poisoning the human body. If a person eats 150 to 300 grams of raw cassava, it can cause poisoning and even death.

Detoxification method: To prevent cassava poisoning, peel the cassava before eating, dip the potato with water, and dissolve the cyanide. Generally, it can remove 70% of cyanogenic glycoside in about 6 days, then heat it and cook it.

4, spinach
Deadly toxin: nitrate

Fatal reason: Spinach is very easy to enrich nitrate. Nitrate itself is very toxic to humans, but it is converted to nitrite by the action of microorganisms in the human body. Spinach is highly prone to nitrates. The new meridian public number suggests that nitrate itself is very toxic to humans, but it will be converted to nitrite under the action of microorganisms in the human body.

Detoxification method: can not eat raw food, must be cooked before cooking. Therefore, it is not advisable to eat the “mutton-mutton” method of eating the soup.

5, broad beans
Deadly toxin: natto

Fatal cause: Vicia faba seeds contain vincristine, which can cause acute hemolytic anemia (fung bean yellow disease) after eating this substance. When eating green broad beans, if cooked improperly, it will often cause poisoning. Moreover, it usually occurs 4 to 24 hours after eating raw beans.

Detoxification method: In order to prevent the emergence of broad bean poisoning, it is best not to eat fresh tender broad beans, and must be cooked before eating.

6, daylily
Deadly toxin: colchicine

Fatal reason: There is a component of colchicine in fresh daylily, colchicine is non-toxic.

However, after absorption through the gastrointestinal tract, it will oxidize to form a highly toxic colchicine, which can stimulate the stomach, causing symptoms such as dryness, heartburn, thirst, abdominal pain, and diarrhea.

Detoxification method: Since colchicine is water-soluble, this plant alkali has been destroyed during the cooking and drying process of fresh daylily. In addition, when eating dried daylily products, it must be soaked in water, of course, there is no poisoning. It is.

7, purslane
Deadly toxins: dust and bugs

Fatal causes: Wild vegetables such as purslane contain dust and insects, which can cause allergies.

Detoxification method: The purslane is boiled with boiling water before eating, which is more hygienic and does not affect the taste and nutrient content.

8, leeks
Deadly toxin: nitrite

Fatal cause: Amaranth contains a lot of nitrite. If the body consumes excessive amounts of nitrite, it can oxidize normal hemoglobin in the human body to methemoglobin. The new meridian public number suggests: In addition, nitrite can also prevent oxygenated hemoglobin from releasing oxygen, which causes the body to be hypoxic, causing human poisoning.

Detoxification method: Be sure to let your family eat fresh vegetables. Cooked vegetables should not be stored for a long time. Pickles should be washed after one month of pickling.

9, soy milk is not cooked and can not drink
Deadly toxin: saponin

Fatal cause: Since raw soybeans also contain toxic ingredients, if the soy milk is not cooked, it can also cause food poisoning. In particular, when the soybean milk is heated to about 80 ° C, the saponin is thermally expanded and the foam floats up to form a “false boiling” phenomenon. In fact, the toxic components such as saponin present in the soybean milk are not completely destroyed. That will cause poisoning, usually after eating for 0.5 to 1 hour, the main symptoms of gastrointestinal symptoms.

Detoxification method: In order to prevent the poisoning of raw soy milk, when the soy milk is cooked, it should be heated to 100 °C after the occurrence of “false boiling”. The cooked soy milk has no foam, and the disappearing foam also indicates that the toxic components such as saponin are destroyed, and then boiled for about 10 minutes on low heat, so that the purpose of safe eating can be achieved.

The above nine vegetables were not cooked, and they were fatal. Forward to your friends, be sure to pay attention to them when cooking, to avoid accidents.
