a lot of people have heard, when吃虾should not eat fruits, seafood, when should not take vitamin C tablets ... ...
Although unclear reasons, but we all heard a serious Warning: This match will be poisoned!
theory are:河鲜seafood is often contaminated, one of a number of arsenic-rich. Originally, five smaller price arsenic toxicity, but if you were like vitamin C reductant reduced trivalent arsenic, which is arsenic (arsenic trioxide), and toxicity of a sharp increase, then there is the danger of poisoning.
However, there is a lot of confused people at the same time to defend themselves: It is now after the feast, we must on fruit ah! I ate seafood there is to eat fruits, and no poisoning ah! This is Why?
the original, have serious harm in violation of taboos, the premise has four:
First, the seafood was indeed arsenic from polluted environment. Except shrimp, have a small lobster, mussel, oysters, a variety of clams, crabs, etc., all kinds of seafood, have been polluted and dangerous concentration of arsenic. If a small seafood from contaminated waters, it would not contain many of arsenic, it does not exist such a taboo.
Secondly, the number of intake of contaminated seafood is indeed more, of which the total amount of arsenic to a value enough to cause poisoning. If you like to eat crabs as Lin,浅尝辄止, small appetite, natural hazards do not see the obvious.
Third, the fruit of vitamin C and other reducing substances in high enough concentration, the quantity is large enough to eat. If only half-apple, banana inside a few films so one bit of vitamin C, are not sufficient to restore a large amount of trivalent arsenic. In contrast, vitamin C tablets in the content will be much higher, and therefore at greater risk of some.
Fourth, vitamin C tablets are seafood河鲜taken shortly before and after. If you take medicine tablets breakfast, evening only吃虾, because most in vivo metabolism of vitamin C has been lost, the danger will become smaller.
In sum, seafood and vitamin C with food and dangerous, is a question of quantity. Aquatic pollution in the end depends on what the negotiations on, the number of seafood to what many on the upbringing, as well as vitamin C to what many in the upbringing on.
arsenic LD50 of less than 15 mg / kg, is generally believed that, 100 ~ 200 mg of arsenic is deadly dangerous. However, our country's fish arsenic standard of 0.1 mg / kg, in other words, if the qualified aquatic eat, then even eat 10 kilograms, it would not happen acute poisoning problem. At present, brought about by the frequent occurrence of seafood arsenic poisoning case can only prove that the seafood on the table has been seriously polluted, hundreds of times more than the national standards!
from another angle, if not with vitamin C with food, seafood,河鲜on enough security?
The answer is obviously negative. To the arsenic level of risk possible, such food is not fit for human food. Price of five arsenic itself toxic, but toxicity to the following one-tenth of arsenic. Chronic arsenic poisoning may cause a variety of cancers, and organ damage, the harm can not be ignored; and these contamination in seafood is likely to contain other pollutants from wastewater, such as mercury, cadmium, lead, organochlorine pesticides, many chloro-biphenyls, as well as many other chemical pollutants. Really do not know, why have so many customers one after the other, with relish to enjoy such high-priced flower food, just be satisfied with "no immediate hospitalization caused by arsenic poisoning," the security!
- no one can say that has nothing to do with their environmental protection. Food on the table where raw materials come from, who can control? Environmental pollution, and everyone suffer!
I personally recommend that if the environmental quality of the product should not worry if河鲜not to eat seafood more than an every day, not to more than 100 grams quantity. Among coarse grains, vegetables and fiber can contribute to heavy metals, and therefore fit to eat with. Ate these foods to eat after the vitamin C tablet, is still a bottom-line safety recommendations.
In addition, we must note that for many seafood河鲜cold, weak stomach people need to eat less. Substantial after eating seafood, eat a large number of cold fruit, for some people, the easier the problem of abdominal pain caused by diarrhea. This has nothing to do with the arsenic contamination.
