It is common knowledge that many people can keep healthy by eating wild vegetables. bracken is a common wild vegetable and has the reputation of longevity vegetable. This is because bracken is rich in vitamins, and there are many ways to do it. Cold bracken is a common food on the family table. What are the benefits of eating bracken?

2. It's true that bracken causes cancer.
There have been rumors in the Jianghu that people who eat bracken often get gastric cancer, esophageal cancer and intestinal cancer. After a series of experiments, we got very authoritative data: Pteridium aquilinum does cause cancer, and it is highly carcinogenic! Pteridium aquilinum not only contains phenyloxalic acid, fern lactam, flavanol compounds and acoflavin compounds, but also contains the strong carcinogen pteridoside!
Protopterin is a substance in Pteridium aquilinum, which is rated as Class 2B carcinogen by the world cancer prevention. The rhizome and leaves of Pteridium aquilinum all contain Protopterin, among which the rhizome contains redundant leaves, and the carcinogen is classified into four grades. Class 2B carcinogen means that it is likely to be carcinogenic to humans and animals, and the evidence of carcinogen to humans is limited. Fresh bracken is bitter and astringent. Treating bracken with blanching water, plant ash and alkaline water before eating can remove the bitterness and astringency of bracken, and reduce the content of protopterin to some extent, but it cannot be completely eliminated.
3. What foods can also cause cancer
1. Pickled foods
Pickled foods have always been side dishes and people's favorite foods. However, this kind of food contains a lot of nitrite, which can be converted into carcinogenic amine nitrite in the body. Ammonium nitrite is a carcinogen, so it should be eaten as little as possible.
2. BBQ food
People like to eat BBQ food both in the north and the south, because the grilled meat tastes more tender, so it becomes people's favorite food. However, you should never eat more of this kind of food, because once the food is burnt, it will produce a lot of carcinogens.
3. Smoked food
Smoked food is a special food in some provinces and cities, and even many family members can make their own bacon. In fact, in the process of making bacon, a carcinogen called benzopyrene will be produced, and it is easy to get esophageal cancer and gastric cancer if you eat these smoked foods frequently. Therefore, it is better to eat less of this kind of food.
4. Fried food
People's taste likes spicy food, and fried food will be very fragrant, so many people like to eat fried food, especially children. However, fried food contains carcinogenic ingredients, because after the food is fried and burnt, it will produce carcinogenic polycyclic aromatic hydrocarbons. Therefore, fried foods should not be eaten more.
5. Moldy foods
The whole grains we eat are prone to mildew, so don't eat them if they are left in a damp and cold place for too long. Never eat moldy food because it is a pity to throw it away. The most moldy foods are rice, wheat, beans, corn, peanuts, etc. Once these foods are moldy, they will produce a strong carcinogen aflatoxin.
6. Overnight vegetables
Now every family has a refrigerator, and the leftovers after eating will be stored in the refrigerator. In fact, this is very unscientific, because overnight vegetables will produce nitrite, which will enter the human body and be converted into ammonium nitrite.
7. Repeated boiling water
Repeatedly boiled tap water contains ammonium nitrite, which can cause cancer.
Facts have proved that Pteridium aquilinum does have a certain carcinogenic effect, but if you only eat it a few times, you will not cause cancer, so you don't have to worry, but you'd better not eat it in the future, just in case, it will be too late to regret it. In addition, there are some foods that are carcinogenic, so you must watch them carefully!
