Vitamin C with shrimp eat poison arsenic as a rumor

The correspondent XuanYing yan

China's traditional Chinese medicine to

        Recently, in the micro letter have a rumors spread widely, crazy forwarded by user: a Taiwanese girl seven holes bleeding suddenly sudden death, the autopsy were judged to arsenic poisoning death. A medical school professor after looked at the dead man's stomach contents that arsenic was produced in the internal, the deceased had a habit of taking vitamin C every day, and eat a lot of shrimp. After Chicago, a researcher at the experiment conclusion: shrimp food contains a lot of high concentration, such as soft shell like five potassium arsenic compounds, although itself is nontoxic, but meet with vitamin C can occur after chemistry, can make the original non-toxic pentavalent arsenic, into a poisonous trivalent arsenic, commonly known as arsenic. Remind, for the sake, people during the period of taking vitamin C, should diet shrimp.

        This rumor, let many people had a habit to eat vitamin C scared, some commonly used medicine added vitamin C, also a lot of fruits and vegetables are rich in vitamin C, and shrimp and a common daily food at the dinner table, if vitamin C in shrimp is poisonous arsenic, people is not easily by the food and drug phase grams for his life in danger?

        Foshan city, guangdong province hospital of department of clinical pharmacy pharmacist Liang Zhiming thinks, this rumor is a rumor, does not, people don't have to worry too much about, if this is set up, it contains a lot of vitamin C of fruits and shrimp as phase grams of food, while in real life, people generally have shrimp phenomenon of fruit to eat, but not seen clinically with similar appalling reports, at the same time, also did not see drug safety management department issued phase grams of vitamin C and food reminds, can be seen that there is no basis.

        In addition, from the scientific point of view, the shrimp are arsenic, but volume is very low, and almost all organic arsenic, the pentavalent arsenic and harmless to human body, vitamin C is the reductant is not false, but in addition to organic arsenic into inorganic arsenic in the first place, but also have enough amount of arsenic and large amounts of vitamin C to reduction of trivalent arsenic, moreover, even if the pentavalent arsenic reduction of trivalent arsenic also is not the same as arsenic, due to the different material of trivalent arsenic toxicity is not the same. Apart from organic arsenic into inorganic arsenic need complicated conditions, but direct food containing inorganic arsenic, rice is the main source of inorganic arsenic, if vitamin C + inorganic arsenic poison arsenic, so eat shrimp at the same time, or eat vegetables that are rich in vitamin C, should not let people worry about phase grams of food poisoning? In fact, eating rice with vegetables and shrimp or, in the Chinese norm on the dining table, but never see in people's life experience is a harm to human body. "The use of vitamin C has a long history, in the vitamin C drug instructions did not have a serious adverse reaction with other food taboo. Vitamin C treatment dose generally does not exceed 600 mg per day, the dosage is very difficult to act as a reducing agent role, while adults daily dietary intake of vitamin C are rarely more than 100 mg, is much lower than the number of treatment." Therefore, shrimp low amounts of organic arsenic even met treatment amount of vitamin C is also a concern, is not enough to constitute a harm to human body.

        Liang Zhiming think, compared to the rumor, don't abuse the vitamin C is more aroused people's attention. Long-term use of vitamin C can cause uric acid salt, cysteine salt or oxalate stones; An overdose can cause diarrhea, skin is red and bright, have a headache, frequent urination, nausea, vomiting, stomach cramps. Normal diet of healthy people to oral vitamin C, if the long-term use of high doses of the application, shall take medicine under the guidance of a doctor.
