The first kind, green beans.

Green beans are often eaten in our daily life, but older green beans are not easy to boil. Some people think that fried vegetables are not nutritious when they are old, so they generally feel that they are almost fried and will be cooked.

However, green beans contain saponin, phytohemagglutinin and other harmful substances. If they are not cooked, people will have poisoning symptoms, such as abdominal pain, diarrhea, vomiting, dizziness, palpitation, chest tightness, cold sweat and other symptoms.

Therefore, we must know more about the cooking temperature, and do it scientifically, so as not to make the food "toxic".

The second kind, fungus.

In the past, there was a report on the Internet that a family was poisoned by cold fungus, and even a child was dying. So how can fungus be poisoned after eating it?

This is because auricularia auricula produces a toxin called "mycotic acid" in the process of soaking hair, and its toxicity is very fierce. The correct way is: in the process of soaking hair, it is best to put it in the refrigerator, or don't soak it for too long. After the hair is done, it should be washed several times to remove the toxins.

In fact, not only fungus, but also other foods that need to be soaked, such as tremella, kelp, water fat, scallops, sea cucumbers, etc., should be eaten in the pot at one time after soaking. It can't be left for a long time, and it is not safe even in the refrigerator.

Third, soybean milk.

Sometimes, I drink soy milk bought outside, or sweet soy milk made by myself. But I feel bloated, dizzy and headache, and even nausea and vomiting. Is this poisoning? Yes

This may be because these soymilk are not cooked at all! Undercooked soybean milk contains saponin, saponin, erythrocyte agglutinin and other harmful substances, which has caused harm to the digestive tract.

The above three are all examples of improper handling of food. Smart people won't be caught, right?
