The poisonous theory of pickled food is not scientific uC.jpg
The claim that pickled food can cause cancer is fundamentally untenable from a scientific point of view. "All cured foods contain toxic substances, but it cannot be said that all cured foods are toxic. Whether there is poison depends on whether the poisonous ingredients in food have reached a quantity, and only after the amount of poisonous effect has been reached can it be said that it is poisonous. He Jiguo, director of the Department of Nutrition and Food Safety, School of Food Science, China Agricultural University, said, "We have eaten salted food for hundreds of years. Suddenly, it is inappropriate to say that it is poisonous. Moreover, some substances in salted food are antiviral in themselves."
He further explained that "nitrite is a strong oxidant, which generally does not harm human health or cause cancer. Most nitrites are excreted with urine in the form of "passers-by". only under certain conditions (suitable PH, microbial action), nitrite reacts with amine substances and converts into carcinogen-nitrosamine. And we usually use cosmetics, edible cigarettes, beer and so on which contain a certain amount of nitrosamines, usually should pay more attention.
Nitrite disappeared after one month of pickling restriction. Generally, there are two kinds of cured food cycle, one is the violent curing, which can be eaten immediately after curing; the other is the long-term curing. In this case, the nitrite content of cured products is the highest within 4 to 8 days of curing, which begins to decline after the 9th day, and disappears in about a month. At this time, it can be used. Start eating.
However, He Jiguo warned that excessive intake of nitrite can cause poisoning. "Like carbon monoxide poisoning, it will cause the body of iron into trivalent iron, hemoglobin loss of oxygen-carrying function, the general human intake of 200 mg will produce poisoning, up to a certain amount (0.3 grams to 0.5 grams) will cause poisoning, and even cause death (more than 3 grams)."
