"Tomato Crab with Poisoning" is a pass

Crabs and tomatoes eat the same amount of acrid cream? Recently, the microblogging of this content has caused users in the Internet to "shock." In this regard, experts said that the possibility of poisoning is unlikely to occur under the existing ecological environment and the conditions of the daily diet.

With the arrival of the crab season, taboos about various crabs are also circulating. Recently, a microblogging of crabs and tomatoes with the same amount of arsenic is widely circulated, claiming that crabs contain pentavalent arsenic. Vitamin C in tomatoes is reduced to trivalent arsenic, which is commonly known as arsenic.

With the widespread forwarding of this Weibo, netizens expressed their doubts and surprises. In this connection, Zhu Yi, associate professor of the College of Food Science and Nutritional Engineering at China Agricultural University, said that in the laboratory, vitamin C may convert pentavalent arsenic into highly toxic trivalent arsenic, but it is not easy to achieve this effect in diet. . First of all, to eat a few kilograms of crabs that have been seriously polluted by arsenic, after which vitamin C is taken more than 500 mg for one time, that is, the possibility of intoxication when a single intake of more than 5 pounds of tomatoes is present. This is clearly the possibility in the current ecological environment and It is unlikely in the daily diet.

According to some netizens, whether or not eating fruits and vegetables rich in vitamin C, such as crabs and tomatoes, at the same time will cause cumulative reactions. Zhu Yi further explained that if it is not eaten once, it will not produce sufficient amounts of response, and in seafood There is also no such high concentration of arsenic.
