This dish was served at the G20 Hangzhou Summit Dinner in 20 16. It's Jiangsu, Zhejiang, Shanghai and Fujian cuisine. And seafood+vitamin C= poison? According to rumors, in June last year, 5438+ 10, a number of online forums pushed the news that "a pair of little sisters in Yancheng died after eating crabs and persimmons". Many people think that not only crabs and persimmons, but also crabs and foods containing vitamin C are at risk of poisoning. Similarly, shrimp and vitamin C eat arsenic together. The identification results show that arsenic in crabs cannot be poisoned unless it exceeds the standard by hundreds of times. Eating a few kilograms of contaminated crabs and 5 kilograms of tomatoes at a time can lead to poisoning. Rumor: Eating more than 5 kg of tomatoes at a time may lead to poisoning.

It is rumored that shrimps and crabs can't be eaten with foods containing VC. In the final analysis, they are worried about arsenic pollution in aquatic products. It should be noted that crabs are easy to cause allergies and food intolerance. But this does not mean that everyone must fast vegetables and fruits containing VC when eating crabs.

In the laboratory, vitamin C may convert pentavalent arsenic into highly toxic trivalent arsenic, but it is not easy in the diet. If you must say that you will be poisoned, eat a few kilograms of crabs with serious arsenic pollution first; After that, the dosage of vitamin C should be more than 500 mg, that is, eating more than 5 kg of tomatoes at a time may cause poisoning. "Can ordinary people eat so much?"

Fan Zhihong, a food safety expert at China Agricultural University, publicly questioned, "If the arsenic in crabs is not hundreds of times higher than the standard, it is impossible to be poisoned." She said that this rumor has been circulating for a long time. "It took us several years to refute the rumor, but we still can't let the rumor continue."

Yi Zhu, a food safety expert, also commented on Weibo: "In the laboratory, vitamin C may turn pentavalent arsenic into highly toxic trivalent arsenic, but it is not easy in the diet."
