Background: The new friend mentioned that there is literature fern Say powder with carcinogenicity. The restaurant's fern root powder, some people say that detoxification, some people say that are carcinogenic, the club would give the literature according to the hope that can clarify these allegations.
see a cancer-causing food ingredients that, first of all not to get too excited about. A lot of food raw materials, eating at inappropriate times may promote the occurrence of cancer, such as ...
- many meat products will increase the occurrence of human breast cancer, colorectal cancer risk, etc.;
- eat pickles pickles, and even that is many yan, will promote the occurrence of the risk of gastric cancer;
- eat more sweets to increase the risk of many types of cancer;
- drink carbonated drinks increased the risk of esophageal cancer incidence;
- eat more smoked fish meat may increase the risk of gastric cancer, and so on.
However, people are still at substantial consumption of these foods, do not seem very intimidating. Minus the efforts of salt is very difficult.
ask a few friends, why do you have to eat meat when it is always so brave? Why eat meat also so happy? Do you not know that there will be Benzopyrene and carcinogenic heterocyclic amines? They said that eating meat all his life, it was no increase in cancer risk, but also not to say that one will eat ah carcinogenic.
right. In fact, the danger lies in long-term, consumption of certain foods in large quantities. After all, the human body has the role of self-regulation, food is not poison, a small amount of consumption, and occasional consumption, may not have much risk. Processing methods, food quantity different, the effect will be very different. Although arsenic can be lethal, a small amount of use it can do the treatment of leukemia.
fern powder on this matter, as long as the experiment to see what to do, they know that it has little dangerous. The experiment are used in the coarse fern root extract. Feeding the animals are feed high-dose 1 / 3, 365 days continuous feeding. Even so, only 10% of animals suffering from intestinal adenoma. In contrast, eating a small amount of powder fern (1/5-1/10) very healthy animals.
want to know the life span of mice were only 2-3 years, they eat fern powder a year, equivalent to human beings to eat the second half. We can not eat every day粉条fern root and can not eat for three decades. That being the case, occasionally eat a little fern root粉条, afraid of?
previous studies have mentioned the possibility of fern root which are water-soluble carcinogens. In other words, if washed many times, will probably wash it. The animal experiments are used in grinding precipitation fern root extracts did not after repeated washing, and human production of fern root粉条time, it will be repeated washing, and then add water to produce substantial粉条, objective on their dwindling the number of possible carcinogens.
study also shows that in the large-scale use of fern powder cases, liver transplantation can reduce cell proliferation. In other words, although the incidence of this tumor may have to promote, on another it may inhibit cancer. So, we should say that it is dangerous, or useful to them?
so that from a risk assessment perspective, the harm was not large, the actual exposure also very small, and occasionally eat fern root粉条are quite safe, basically do not have to consider questions carcinogenic. In contrast, because of this kind of thing does not digestible starch for digestion and less capable people who eat more may cause bloating problem, it is more worthy of consideration.
But why people's meat, pickles, sweet drinks, such as food rather indulge on some other food is very harsh on them? For example, I believe, as long as someone talking about rats ate fern powder only a small number of cancer-causing this, I am afraid a lot of people no longer eat the fern root powder.
I think, that might be an emotional problem. People familiar with the food of their comparison of tolerance for an unfamiliar food was very worried; people of their favorite things are willing to risk less of their own longing for the things would not run the slightest risk.
as death someone is willing to eat fish, but someone clearly gout eat seafood, obviously someone has diabetes should eat these sweets ...... something harmful, it is not straightforward to put in front of it? However, it was for sensual enjoyment, but willingly to take dangerous.
view, really want to stay away from risks in food, we still should be a little more rational, and grasp some basic principles. First of all, any food in the diet have a reasonable share of the excess can not eat, such as meat taste; followed by the frequency of food consumption and the risk of the size of every day is dangerous to eat, and occasionally eat a little then need not be so worry; Finally the role of food and physical conditions, for different physical person, the advantages or disadvantages of food may differ materially.
know that these, in determining the information on foods, you can not so一惊一乍less the fear.
