But for this wild, there is a saying on the Internet that ferns can cause cancer and should be blacklisted. So, is this really the case? Can I eat delicious Baidang? Today's doctor's results may be different from yours. Let's have a look.
Why do you say that about bracken?
This is the reason, because in the unintentional article of American food engineering, bracken contains the original Fernoside. After entering the human body, it will react with amino acids, leading to human genetic material. Destroy, thus increasing the risk of esophageal cancer and gastric cancer, endangering human health. In addition, the International Agency for Research on Cancer also assessed Pteridium aquilinum as a 2B- stage carcinogen.
For this statement, we read the literature findings, and in 1960, scientists made a test. I fed five cows with bracken, and then found that the levels of platelets and white blood cells decreased in cows. Among them, there are three cows with tumors in their bodies.
In fact, the fact that ferns cause cancer.
But for this view, many professionals have made clarifications, and their key points are summarized as two points:
First, the concept that 2b causes cancer must be clear.
When he hears about carcinogens, many people will become war, thinking that you can't eat and there will be cancer. But in fact, carcinogens also score, such as alcohol, betel nut, processed meat, etc. As first-class carcinogens, it has been confirmed that cancer occurs directly. 2a caravans, such as red meat, fried food, etc., which means that it is likely to cause human cancer.
However, bracken, as a class 2B carcinogen, may cause human cancer, similar to this kind of coffee, low-frequency electromagnetic waves, diesel oil and so on. The evaluation standard of 2B carcinogenicity of the International Agency for Research on Cancer is that there is not enough evidence to show that the substance is carcinogenic to human beings, but it has enough evidence to show that the substance causes cancer, and the above substances will also explain this.
Second, the dose of vomiting is harmful, and everything is playing rogue.
In fact, the carcinogenicity of bracken has been tested in mice as well as cows, and the results are the same, which proves that there is a risk of cancer. However, people are not animals, and the same substance has different effects.
In addition, if the amount of mouse feeding causes cancer, it is equivalent to letting a person eat 350 grams to 3.5 kilograms of bracken every day, which will last for more than 20 years. Obviously, this is very unrealistic. The reason is that bribery is also a seasonal vegetable, and it is impossible to eat it every day. Besides, no one eats bracken every day. It's too delicious. Of course, the original bracken in ferns will decompose after boiling in high temperature water, and the concentration of carcinogens will decrease. In this case, even if you like to eat bracken, the storage conditions are better, and there may be many cancers. Therefore, you want to cause cancer by eating bakers instead of reality.
In a word, we can conclude that the risk of carcinogens is very low, and they can be eaten without being blacklisted.
How to eat healthy?
Studies have confirmed that the original bracken in ferns is a very volatile substance, and the purified original chain protein is decomposed at normal room temperature. The carcinogenic effect of boiling water based on primitive Jinling element will be greatly reduced. In addition, the original Flandin is water-soluble, so if you want to eat bracken healthily, you should wash more water before eating it, or use open water to remove the original Fernos.
Abstract: Pteridium aquilinum can relax, but make water and boiling water before eating to reduce the concentration of carcinogenicity and reduce carcinogenicity. For the carcinogen of bracken, it is one-sided, so we should treat it and not waste it.
Real cancer-causing foods are like this, which are usually avoided.
Mildew Soybean —— Aflatoxin
People who like to drink soy milk in their lives may hoard a lot of soybeans. However, due to improper storage, soybeans are like molds. Mold soybeans will produce papain and yellow yogurt during metabolism. This substance is highly carcinogenic, which is 68 times as much as cream. As long as it needs a little, it can cause poisoning.
When yellow pigment was as early as 1993, it was defined as a base factor. Liver function is destroyed after entering the human body, which increases the risk of liver cancer.
