Potato is a kind of vegetable that everyone likes to eat now, but we must pay attention to it when cooking. Don't cook potatoes when the temperature exceeds 120 degrees Celsius, because potatoes will produce carcinogenic acrylamide at high temperature, and people will be easily poisoned once they eat them.
Celery is a common food. Researchers have tested several celery samples in the market and found that 13 different pesticides can be detected in one celery sample, so everyone should cook celery in boiling water for about 30 minutes before eating it to avoid poisoning!
Liu Su, Ph.D., Institute of Botany, Chinese Academy of Sciences, said in Weibo that Gynura bicolor contains pyrrolizidine alkaloid, which is hepatotoxic. People are advised not to eat this wild vegetable. He introduced that Gynura bicolor belongs to Compositae, Senecio and Gynura bicolor in taxonomy. In the last century, chemists found that pyrrolizidine alkaloid (PA) was widely found in Senecio plants. A large number of animal toxicity experiments proved that PA had strong hepatotoxicity and could lead to liver cirrhosis. In addition, it has carcinogenic and teratogenic effects and can lead to primary pulmonary hypertension.
