Healthy kitchen

Mid Autumn Festival is approaching, it is time to eat crabs, eat seafood in this season but has delicious food. Although the crab is good, but when eating should also pay attention to food taboos, which foods can be eaten with crabs, which foods can not eat crabs?. In some time ago, a Heilongjiang female doctor point spread crab + tomatoes = in radio, television, the network was eating arsenic, many experts argue.

The day before the China sound "peak Evening News" reported a "crab tomatoes with food produce arsenic" news, sparked heated debate.

The report said, autumn is a good time to eat crabs, recently on the Internet there was a relevant "tomato stew crab" dishes has attracted attention and controversy, and even friends bluntly, tomatoes and crabs eat together can produce highly toxic arsenic.

In this regard, the Department of Dermatology of Heilongjiang Hospital chief physician Wei Juan explained: Crab not only can't eat tomatoes together, and those who contain vitamin C ingredients are not suitable with crabs eat together, otherwise the consequences will be very serious. She said, crab is crustaceans, containing pentavalent arsenic, what does not damage to the human body, but in the role of vitamin C, will become trivalent arsenic, arsenic is the old people said.

River crab crab Harbin city manager Huanggong further suggested: Crab try not to and tomatoes, cold drinks, tea, peanut sauce, will produce some allergy symptoms. It is reported that Beijing satellite TV and other related broadcasts were also carried out.

Three micro-blog celebrities retort: "impossible!"

Then, crabs and tomato eat together, it will produce toxic arsenic to life? Yesterday, many netizens said, "scared."". But soon, various arguments were made to refute the claim

Fan Zhihong: it took us a couple of years to say the rumor, but we still couldn't hold the rumor back

Yesterday, "eating crabs and tomatoes with poison," said, also attracted the China Agricultural University food science and nutrition engineering institute two food safety experts attention.

Fan Zhihong, a well-known associate professor at the hospital and a more active celebrity on micro-blog, openly questioned, "if the arsenic in the crab is not hundreds of times higher than normal, it can not be poisoned."." She said it was a long circulated rumor that "it took us a few years to refute the rumor", but it still couldn't stand the rumor going on.

Fan Zhihong said: "the rumor crab and VC containing food cannot eat together, after all is about the problem of arsenic contamination of aquatic products. It should be noted that crabs are susceptible to allergies and food intolerance. But that doesn't mean everyone must eat vegetables and fruits without VC when they eat crabs."

Zhu Yi: once a few kilograms of contaminated crabs and 5 pounds of tomatoes may be poisoned

Associate professor Zhu Yi of the Institute on personal authentication on micro-blog said: "in the lab, vitamin C may make changes to pentavalent arsenic arsenic toxicity is very strong, but the food is not easy."

She said: "first of all, to eat several kilograms were serious arsenic pollution crab; after a one-time dose of 500 mg of vitamin C, is a one-time intake of more than 5 pounds of tomatoes have the possibility of poisoning, ordinary people can eat so much?"

"Cloud unintentionally": the human body is not a chemical reactor, "arsenic transformation" is only imaginary

Fan Zhihong micro-blog issued a lot of support, including Peking Union Medical College Hospital, such as science writer squirrel clouds rumor: "even as hundreds of times exceed the standard, pentavalent arsenic into trivalent arsenic is just one kind of conjecture (the human body is not a suitable chemical reactor)."

Others were even more white. "This is not a chemical experiment of" 1+1=2 ". The two elements together can produce third elements," white says.

"VC cannot eat crabs and pass for more than 10 years

Yesterday, reporters found that since 2001, there is often a similar story was pirated online:

Somewhere, a girl suddenly died with signs of bleeding. After a preliminary autopsy concluded that, as a result of arsenic poisoning death. A medical school professor was invited to help solve the case. He carefully examined the dead in the stomach after extract said: "arsenic is in the abdomen." The deceased every day to take vitamin C, dinner and ate a lot of shrimp -- that's the problem!

Two experts in Nanjing said: "impossible!"

Yangzi Evening News reporter yesterday also interviewed Nanjing's chemical and food experts. They also think that eating crabs and tomatoes is no big deal.

Theoretically possible

But the truth is, it won't eat so much

Nanjing Agricultural University College of food science, food safety and nutrition expert Ann Xinxin said, had never heard of anyone eat tomatoes and crabs after arsenic poisoning.

In principle, arsenic is a nonmetallic element, usually not a single substance, but mainly in the form of oxides. The crab is pentavalent arsenic is a compound may be reduced in tomato VC into trivalent arsenic, but this is only in theory." The teacher said, in fact, very little possibility of cooked crabs and tomatoes will generate arsenic, because it requires very large amounts of arsenic and VC can only generate arsenic.

However, most of the crabs on the table are examined by the quarantine authorities. The content of arsenic is very little. Even if it is reduced by VC, it will not affect the human body. "In addition to you eat a lot of crabs, and swallow many, many tomatoes, otherwise there will be no problem."." "If the crabs are contaminated and the arsenic levels are high, it's really harmful for people to eat," says Mr ann."

Arsenic is boiled at high temperature

Direct sublimation, nothing

A chemical expert at a university in Nanjing told reporters that the chemical principle says the arsenic oxide will be reduced to arsenic trioxide when it meets VC, but only if there is a lot of arsenic. What's more, arsenic is an unstable element, insoluble in water. Arsenic after high temperature cooking or stir, not into the liquid, but direct sublimation, "tomatoes and crabs in a food should not be a big problem."

Gaochun crab breeding large: I have eaten for more than 20 years, crabs and tomatoes have eaten together, never poisoned

"I may be the most crab eating person in China, but I never heard that crabs and tomatoes would be poisoned together."." Yesterday, the famous Gaochun crab farming households, households in Gaochun County Shuanghu crab company history unity of Yangzi Evening News reporters.

The history of United said, you eat crabs for at least 20 years, because of their own breeding crabs, so do not eat every year in addition to 5, 6 and two months, all year round to eat crabs in China, there is no one to eat crabs have I got". But over the years, history has never been poisoned by eating crabs and tomatoes, and he has never heard of similar cases around him.

"Coincidentally, I ate crabs and tomatoes the night before," and history firmly denied that it would cause poison. The day because there are several friends to supper at night, when she cooked a pot of crabs to eat the food on the table and a bowl of tomato soup, "it is normal to eat, one day later, did not see any people poisoning."

As to eat crab Master, history of unity, because the crab is cold sex thing, eat crab to drink liquor, vinegar, ginger to eat what.

Jiangsu food and beverage industry association said: "rumor has long been heard, but done so many years of food has not seen."

Food Association bag teacher introduction, since ancient times, in the traditional diet culture, no crabs and tomato grams of the taboo. But he says there is no "tomato stew crab" in culinary cuisines across china. However, in Nanjing and other places, when eating crabs, there are tomato soup, tomato scrambled eggs, but it is possible.

The teacher said the package crab or steamed crab, crab, or put out. In the system of Huaiyang cuisine, every year autumn crabs rise season, a famous dish is crab lion head. In addition, the crab for ingredients of food and crab shrimp, crab soup etc.. The tomatoes and crabs table is not unusual, people's life, often eating crabs, while still a Scrambled Eggs with Tomato Home Dishes etc..

As for the so-called "tomatoes and tomatoes" circulated on the Internet, "eating poisonous words", the package teacher said he heard about it in the early years, but years of cooking experience told him that this is impossible.

Bao said the teacher, this statement from a practical point of view, obviously not reliable. Chefs commonly used ingredients, rich in vitamin C, in addition to tomatoes, there are lemons, cucumbers and so on, and never heard of crabs and they can not be at the same table. In fact, over the years, I have never heard of any poisoning caused by eating these ingredients together.

The food that cannot be eaten with crabs is not the tomatoes, but the persimmons

Interview, Gaochun crab farmers history told the Yangtze Evening News reporter: best not to mix together, eating persimmons, rather than tomatoes.

According to him, persimmon is not mixed and crabs eat, because two things mixed together after condenses into pieces, "besides collywobbles outside, may have to stone", so often eat crab people know, crab and persimmon cannot be mixed together to eat.

For the "crab is best not to eat together with persimmon," the statement, the Jiangsu catering industry association culinary expert teacher agrees.

He said, from a health perspective, people will summarize some grams of food, crab and persimmon is one of them. The reason is that both are cold, and eating together in the stomach can produce a polymerization effect that can cause stomach damage. But Yangzi Evening News reporter learned that even if this statement, but also the lack of more in-depth study of the relevant experts and experimental verification.

For crabs and persimmons can not be eaten together, Fan Zhihong said: "crabs and persimmons taboos are recorded in ancient books.". But the effect varies. Some gastrointestinal sensitive people eat crabs and persimmons (including pears, sugar cane, bananas and many other fruits), even if only to eat one of them, may cause gastrointestinal discomfort. But many people with good digestive function eat it out. It is not a universal rule, but can be regarded as a cue for people with poor gastrointestinal function."

The idea that crabs can't share food with tomatoes is fake, but shrimp can't be eaten with VC at the same time. It's true, and if you take the shrimp and VC for a long time, it's a chronic suicide. For more dietary taboos, check out what you recommend for your reading!
