The internet age has brought people quick information, but some news will be misleading and sensational. If there are rumors? Someone died from eating shrimp and fruit poisoning together? According to the news, shrimp contains pentavalent arsenic, which meets vitamin C in fruit. As a reducing agent, vitamin C can react with arsenic pentoxide to produce arsenic trioxide. Arsenic trioxide is arsenic, which is highly toxic and can cause death. So come to the conclusion: shrimp and fruit? Eat like a gram? . Is that really the case?

Next, I will elaborate.

Is eating shrimp with fruit really like eating arsenic?

Our country's health theory stresses the theory that food can't be eaten with fruit, but it has never been put forward. Now it has been explained that pentavalent arsenic in gastrointestinal tract can be reduced to trivalent arsenic under the action of reducing agents such as fruits, vegetables and medicine vitamin C, and these trivalent arsenic is arsenic. The essence of shrimp and fruits is arsenic poisoning, and the most serious result is sudden death.

This statement has no experimental basis at all. It is true that pentavalent arsenic is low in toxicity and trivalent arsenic is high in toxicity, but it is not that pentavalent arsenic magically becomes trivalent arsenic when it meets reducing agent.

This requires at least three conditions.

1. must be changed from organic arsenic to inorganic arsenic.

2, there is considerable concentration.

3. It needs a period of training.

It has not been digested after meals, so it is unlikely that organic arsenic will be digested and released into inorganic arsenic in a short time. The so-called eating a lot of shrimp, which only contains dozens of micrograms of arsenic, mixed in a meal of food, dozens of micrograms of arsenic concentration is about hundreds of thousands. As for the culture time, its length is related to pH value and drug concentration, at least not? Did the food pass through the intestine? Can be solved.

Trivalent arsenic is not equal to arsenic, and the toxicity of different trivalent arsenic substances is very different; Arsenic is solid and insoluble in water. The reduction process of pentavalent arsenic should be completed in solution, which is physically different? Item? Things. Therefore, we have reason to believe that it is too late for pentavalent arsenic in shrimp shells to be converted into trivalent arsenic in gastrointestinal tract.

Shrimp and fruit have no basis, but they should not be overdone.

Finally, once again,

Through a large number of experiments, scientists found that the arsenic content in shrimp and crab seafood is not much, and the arsenic pentoxide content in each kilogram of shrimp does not exceed 0.5 mg, and the dose of arsenic (arsenic trioxide) causing poisoning is 50 mg. According to the conversion coefficient, if the arsenic contained in shrimp reaches the maximum limit of 0.5mg/ kg and there is enough vitamin C to react with it, a person needs to eat at least 40 kg of shrimp to reach the toxic dose.

But how can a person eat so many shrimps? ?

Therefore, it is unfounded to mention the above shrimp and fruit, but it should not be overdone.

All in all,

There is arsenic in shrimp, which is true, but it is arsenic betaine, which is not very toxic and has a low dose. So it is impossible to cause acute arsenic poisoning.

So don't believe those rumors that shrimp and fruit will be poisoned together. Seafood and shrimp products purchased through formal channels can be safely eaten.
