Ten Toxic Vegetables to Avoid Eating
1. Fresh Mushrooms: Fresh mushrooms contain a photosensitive substance. After ingestion, it spreads through the bloodstream to skin cells and, upon exposure to sunlight, triggers photodermatitis. This toxic photosensitive substance is also easily absorbed by the pharyngeal mucosa, causing pharyngeal edema.
2. Fresh Daylilies (also known as Golden Needle): Fresh daylilies contain toxic colchicine. Once ingested, it causes dry throat, thirst, burning sensation in the stomach, nausea, vomiting, abdominal pain, and diarrhea.
3. Green Tomatoes: Unripe tomatoes contain alkaloids, which can cause poisoning when consumed.
4. Sprouted Potatoes: Sprouted potatoes produce large amounts of solanine, leading to poisoning upon consumption. When using sprouted potatoes, remove the sprouts, sprout roots, and any green parts of the skin, then soak them in clean water for over two hours.
5. Fresh Broad Beans: Some individuals lack a specific enzyme; consuming fresh broad beans can trigger allergic hemolytic syndrome. Symptoms include general weakness, anemia, jaundice, enlarged liver, vomiting, fever, and, if untreated, death due to severe anemia.
6. Uncooked String Beans: Raw string beans contain saponins, which can cause poisoning. Cooked string beans are non-toxic.
7. Spoiled Ginger: Spoiled ginger produces a carcinogenic substance called safrole, which can induce liver and esophageal cancers.
8. Spoiled Vegetables: Under strong bacterial action, nitrates in spoiled vegetables are converted into nitrites. Once ingested, these substances impair the blood's ability to carry oxygen, causing oxygen deficiency and symptoms such as headache, dizziness, nausea, vomiting, increased heart rate, and muscle cramps.
9. Fresh Green Beans: Fresh green beans contain saponins and alkaloids, which are toxic, but these break down when heated. Before eating, blanch thoroughly in boiling water, fry briefly until color changes, or cook dry until browned.
10. Spoiled White Mushrooms: Spoiled white mushrooms produce large quantities of Bacillus cereus, causing gastric discomfort; severe cases may result in toxic shock.
