In December, did you catch the import rumors
Rumor two
Do crabs and tomatoes eat like arsenic?
Truth: experiments show that organic arsenic is not converted into toxic inorganic arsenic
It's time to eat hairy crabs again. While enjoying them, some old ballads about hairy crabs take advantage of the hot spots. Recently, it was announced that crabs can't be eaten with tomatoes. This is because vitamin C of tomato can transform organic arsenic in crab into toxic inorganic arsenic, and reduce low toxic pentavalent arsenic to high toxic trivalent arsenic. The arsenic that people fear belongs to trivalent inorganic arsenic. Is it true?
In order to restore the truth, the director of the 315 party in 2018 entrusted Beijing food safety monitoring and risk assessment center to do an experiment. He took crab roe and crab meat, added mashed tomatoes in the proportion of 2:5, and then added artificial gastric juice prepared according to the method of Chinese Pharmacopoeia. After mixing, he put it in the incubator for 3 hours. After adjusting the pH value, he added artificial intestinal juice, and then mixed it in constant temperature Keep the incubator warm for 2 hours. The above steps basically simulate the human digestion process. After that, arsenic in crab was extracted and determined. The results show that organic arsenic is not transformed into toxic inorganic arsenic, especially trivalent arsenic with high toxicity.
So, what's the reason why a few people feel uncomfortable after eating some two kinds of food?
Fan Zhihong, an associate professor in the Department of nutrition and food safety at the school of food science, China Agricultural University, once said that on the one hand, seafood and river fresh food contain a high proportion of pathogenic bacteria. If they are not fully heated, they are prone to bacterial food poisoning; on the other hand, there are gastrointestinal function problems. People who are weak in constitution, indigestion, afraid of cold and prone to diarrhea should pay attention to eating them less. Therefore, we should choose food according to our physical condition and digestive capacity, and pay attention to the nutritional balance of our diet. Superstition that all kinds of food match each other will mislead us to deviate from the general direction of healthy diet.
