There is a mountain home known as \But that I was born, had no eat any more. Until my high school, but heat up the plant gradually to its price beyond most \Even with specialized processing plant, installed in a beautiful box, exported to other places. I also know that this vegetable's scientific name: Bracken. According to legend, it is not only \
So I listened, so the letter was. Holiday home, but also to buy some to eat. Return to the city, but also bring a number of a friend, often welcomed. One day, when access to other information, inadvertently discovered: the \
fern is the world's most widely distributed one of several plants, in several continents, in many places it in the bud as a vegetable, starch extracted from the root. 100 years ago, it was noted that the plant can cause poisoning in cattle. A large number of edible fern - fern is its bud - the cattle, the fastest in the weeks after the death. And eating less and more, the gradual loss of bone marrow function, leading to a lack of white blood cells, thrombocytopenia, and acute symptoms of bleeding and so on. The sheep eat bracken will be losing her sight. Twentieth century, the sixties, more ferns also found to cause cancer. This discovery caused great interest in scientists,Men of Love, many of bracken tossing mice carrying various animals, confirmed the fern plants can indeed lead to this cancerous animals.

if a synthetic material or processed foods, such \However, the fern is an \Even if we have more \Bracken, still chased by people.

\This too challenges people's mental limits. The fern is the first and perhaps only so far found a way to cause cancer of the edible plants. As a result, scientists tirelessly, to find out where something was carcinogenic. In nearly two decades, many people attempt failed. Look, this carcinogenic substance is very unstable, difficult to be separated, but conclusive evidence of carcinogenicity is not so easy. The early eighties, a Japanese scientists successfully isolated a thing called ptaquiloside, Chinese translation seems more reasonable is the \Since then, many people on this thing for a lot of tests and found that using it to feed animals, what can appear in front of those symptoms. It can also be found in the biochemical reaction with the amino acids can also damage the genetic material DNA. That is, it's toxic even stronger than imagined. Worst, it can be transferred to food from cow milk, and can spread to the water and soil. If the cow ate ferns, then Dallas will occur even eat milk fern poisoning symptoms. This may also explain: fern growth areas were strong, even eat bracken, esophagus cancer risk is still much higher.

However, people are \After all, sometimes the results of animal experiments can not occur in the human body, while the incidence of cancer in itself is not so high - more than doubled twice, it does not intuitively understand the system enough. Even if some people get cancer, and also difficult to suspect that this fern to cancer in humans do not know why the age thing began to eat. On the other hand, people eat only tender fern shoots - is not its role as ginger as the \Or, when people eat bracken to conduct the cooking process will not destroy the toxin it?

because the original fern glycoside was separated out, the above two issues are a good validation. Science found that the original fern glycoside in the fern are all part of, and eating fern - fern of the tender part of the content, higher! However, the people a little peace of mind is fresh bracken bitter astringent, in addition to individual endless pursuit of \And this treatment will greatly reduce the content of the original bracken glycosides. The milk, the general is also subject to high temperature sterilization treatment, it will greatly reduce the original fern glycoside toxicity.

However, such treatment is lower, not eliminate. For humans, eating certain processed bracken, generally will not break like the cattle ring as bone marrow, or as blind as sheep. However, chronic toxicity, such as cancer, will arise?

seventies the twentieth century, in the mountainous central Japan investigated the relationship between eating bracken and esophageal cancer. Found that residents there eat bracken makes the incidence of esophageal cancer for men increased by 2.1 times, while women increased by 3.7 times. North Wales in the UK, has a high incidence of stomach cancer. 1990, conducted a \Similar studies elsewhere in the world has done some, the results are basically consistent.
