1. Beans: Beans such as green beans, lentils, red kidney beans, and white kidney beans can cause poisoning if eaten raw or not thoroughly heated.
2. Uncooked soy milk: Raw soybeans contain toxic components. Consuming uncooked soy milk can lead to food poisoning.
3. Cassava: The roots, stems, and leaves of cassava all contain toxic substances. Eating raw or uncooked cassava or drinking its soup can cause poisoning. The toxins can lead to neurological paralysis and may even result in permanent paralysis.
4. Sprouting potatoes: The toxin in the sprouted parts of potatoes—solanine—is tens to hundreds of times higher than in the flesh. If accidentally ingested, mild symptoms include impaired consciousness and difficulty breathing. In severe cases, it can be fatal due to heart failure and paralysis of the respiratory center.
5. Fresh wood ear mushrooms: Fresh wood ear mushrooms contain a porphyrin photosensitive substance. This substance is sensitive to light. After consumption and exposure to sunlight, it can cause solar dermatitis. In severe cases, throat edema can lead to difficulty in breathing.
6. Fresh daylilies: Daylilies contain colchicine, a toxin that can cause poisoning symptoms such as a dry throat, a burning sensation in the stomach, and hematuria. Before consumption, daylilies must be boiled thoroughly, then blanched in boiling water, and then cooked.
7. Green tomatoes: Green tomatoes contain the toxic substance solanine. Eating these unripe green tomatoes can leave a bitter taste in the mouth and lead to poisoning symptoms like nausea and vomiting. Eating them raw is even more dangerous.
8. Rotten ginger: Rotten ginger produces a highly toxic substance called safrole. Even a small amount of this toxin can cause poisoning and degeneration of liver cells in humans.
9. Bamboo shoots: Fresh bamboo shoots contain a natural toxin called cyanogenic glycosides. Eating raw or undercooked bamboo shoots can also cause food poisoning.
