2. Toxins from mushrooms

In fact, there are many types of mushrooms: some are harmless and some are poisonous. Anyone who is unlucky enough to eat poisonous mushrooms will have to learn the final lesson. Poisonous mushrooms are often found in the forest at the beginning of the rainy season or wild mushrooms growing along the roadside. Poisonous mushrooms are divided into 2 groups: the group of mushrooms that show early poisoning symptoms within 6 hours after eating, typically amanita muscaria, anipantherina, red mushrooms or sun mushrooms.

People who are poisoned have symptoms of nausea, vomiting, diarrhea, muscle spasms, muscle pain, hallucinations... usually not fatal. Highly virulent mushrooms, causing high mortality, typically amanita phalloides, A. ocreata, A. verna...

People with poisoning have symptoms that appear late after eating mushrooms from 6 - 24 hours or 48 hours later with the following manifestations: nausea, vomiting, abdominal cramps, diarrhea, little urine, dark yellow urine, yellow eyes, liver failure and acute kidney failure. The risk of death is very high if not detected and treated promptly.

3. Toxic substances in bamboo shoots

Cyanide is a toxic substance in bamboo shoots. A study on three types of bamboo shoots showed that: white bamboo shoots (grated from bamboo shoot roots), white bamboo shoots soaked in water for half a day, at which point the bamboo shoots released slightly sour water, and yellow bamboo shoots, which were boiled and soaked in water and sold on the market, all had very worrying levels of cyanide.

The cyanide present in bamboo shoots will gradually decrease when exposed to water. However, for pickled bamboo shoots, during the soaking process, cyanide can combine with some enzymes or combine with some substances in the human intestine, causing acute poisoning. Therefore, when preparing bamboo shoots, you should follow folk experience by washing thoroughly, soaking bamboo shoots in water for many hours and boiling 1-2 times before eating to avoid poisoning.

4. Cassava also contains cyanide.
