First, the historical origin of bracken
Since ancient times, people have special feelings for wild vegetables, and all previous dynasties have regarded wild vegetables as disaster relief funds in famine years. Pteridium aquilinum (also known as fist dish), known as the "king of wild vegetables", has a longer history.
The Book of Songs, Zhao Nan, leans towards Nanshan and picks its ferns.
"This is the earliest evidence that Pteridium aquilinum has entered the vegetable field." Eryayi ""Pteridophyte is like a child's fist, purple and fat.
Bai Juyi, a poet, said that bracken has always been given to children as fists, but he revealed the origin of fist dishes. Boyi and Shu Qi don't eat the story of Zhou Su picking ferns and reeds in shouyangshan, which gives her a lofty and secluded feeling.
Second, the nutritional value of bracken
Pteridium aquilinum is rich in various protein, cellulose, vitamins and minerals needed by human body, and has the functions of refreshing, degreasing, helping digestion, clearing away heat and toxic materials, etc. The processed bracken can be mixed, fried, souped and pickled. Cold bracken, dried bracken, spicy bracken and bacon bracken are common wine dishes, and the dishes are ruddy and fresh.
Can wild bracken in rural mountainous areas be eaten?
The theory that bracken causes cancer has a long history, and I believe many friends have heard of it.
Pteridium aquilinum is extremely rich in nutrition, and the flavonoids in it also have the functions of anti-tumor, anti-oxidation and anti-free radical. But bracken also contains a substance called protopterin, which is considered to be a carcinogen to human beings.
So, can wild bracken in rural mountainous areas be eaten? Of course, you can eat it. Just pay attention to the way you eat it.
(1) It is not advisable to eat bracken in large quantities frequently.
Fern does contain carcinogens, but it doesn't mean that you will get cancer if you eat it. Only a long-term large amount of protopterin can cause cancer.
If you eat too much rice, you may die. Food safety should not be divorced from dosage. Pteridium aquilinum is just a seasonal wild vegetable, and it is no problem to eat it occasionally or in small quantities. No one can eat bracken as a meal.
(2) Fresh bracken should be blanched.
Why do cattle and sheep have poisoning symptoms when they eat bracken, but for thousands of years, there are few patients who eat bracken to cause cancer? Protopterin exists in all parts of Pteridium aquilinum, and the content of Pteridium aquilinum tender part is high. After boiling, the protopterin in bracken will not be eliminated, but it will be greatly reduced.
Cattle and sheep eat fresh and untreated bracken, while humans eat bleached and boiled bracken.
When the bracken is blanched, it is best to put some salt or alkali, which can also reduce the bitterness and earthy smell of some bracken itself.
(3) Protopterin belongs to Class 2B carcinogen.
Protopterin was assessed as a class 2B carcinogen by the World Cancer Organization. The so-called class 2B carcinogen is a classification of carcinogens, which means that there is limited evidence of carcinogenicity to humans, insufficient evidence of carcinogenicity to experimental animals, or insufficient evidence of carcinogenicity to humans and sufficient evidence of carcinogenicity to experimental animals.
Simply put, it is a substance that may cause cancer to human beings.
Compared with the primary carcinogen, wild bracken is much safer. Tobacco contains more than 40 kinds of carcinogens, and pickled food, smoked food and barbecue food are all listed as serious carcinogens. Have you ever controlled your mouth?
Summary: Wild bracken in rural mountainous areas can be eaten, as long as you pay attention to how to eat it.
It is not advisable to eat bracken in large quantities often. Fresh bracken should be blanched to reduce the content of protopterin. It is best to put some salt or alkali when blanching, which can also reduce the bitterness and earthy smell of bracken itself.

Efficacy, Function and Taboo of Pteridium aquilinum 1
First, does bracken cause cancer?
Pteridium aquilinum can cause cancer. It contains some substances unique to cancer, which exist in roots, stems and leaves, but these substances are related to the consumption. Eating once or twice occasionally won't cause cancer, but eating for a long time will be harmful to human health.
And it is generally eaten by heating, which will reduce the content of carcinogens.
But for the sake of health, we should eat less of this food and try not to eat it.
Second, the edible value of bracken
This species can be used as medicine, and the stems and leaves can cure fetal toxicity and eliminate phlegm accumulation; Young leaves can be used as vegetables.
General bracken often tastes bitter and astringent. Boil it first, then wash it with water, and eat it three to four days later.
You don't need to cook the bracken, just remove the old one and wash it.
You can fry it directly.
Fried bracken, it is best to use vegetable oil. When the oil is hot, stir fry and add salt, ginger, pepper and lobster sauce. Add garlic slices and monosodium glutamate before frying and mix well. A delicious plate of bracken is ready.
Need to be reminded: water bracken should be fried as soon as it is washed, and it tastes fresh with a little water.
Third, the efficacy and role of bracken
1, promoting blood flow
Because some people's blood flow speed is slow, and they usually don't pay attention to their health, they often like to eat some foods that are too greasy and irritating, and the blood viscosity further increases, which leads to the blood flow speed of the human body being much slower than others, thus leading to serious blood diseases. If we want to alleviate this disease, we need some targeted foods to effectively cure some people's blood diseases.
Step 2 detoxify
There are many ingredients for detoxification. In ancient times, if people were bitten by poisonous snakes in the mountains, they would simply treat the wounds themselves and use some foods that can detoxify quickly to promote the discharge of toxins from the body.
In ancient times, Pteridium aquilinum was a very popular food. Some people used Pteridium aquilinum to promote the excretion of toxins in the body, and this is actually the case now.
Step 3 stop bleeding and relieve pain
The medicinal effects of bracken are far more than the above. If you say that you have suffered from massive bleeding or pain all over your body, it is recommended to eat bracken.
In this case, taking bracken can obviously help people stop bleeding and relieve pain quickly.
It can make people's discomfort disappear, and now some people often stumble carelessly. It is suggested that these people can eat more bracken in spring.
This can also have the most basic health care effect on people's bodies, and at the same time enjoy the delicious food.
From the above introduction, there is a certain scientific basis for the claim that bracken causes cancer, but it is only possible to cause cancer on the basis of a certain consumption. Generally speaking, our normal consumption is relatively safe, so don't worry. As long as we eat it properly, bracken still has many benefits and functions for us.
Pteridium aquilinum contains many nutrients, such as cellulose, vitamins and minerals. Eating it correctly and in moderation will generally not cause adverse effects on the body.
However, Pteridium aquilinum contains protopterin and other toxic substances, so eating Pteridium aquilinum has certain taboos.
1. It is forbidden to eat raw bracken: before eating bracken, it is recommended to soak it in alkaline water, then blanch it with boiling water for 2-3 minutes, and then wash it with clear water for many times, so as to minimize the content of protopterin, reduce the risk of poisoning, and at the same time, make the astringency disappear and improve the taste;
2, taboo to eat more: eating a lot of bracken will make protopterin accumulate in the body, which will lead to food poisoning, abdominal pain, diarrhea and other discomfort, and even lead to neurological symptoms.
Therefore, it is suggested to control the frequency and intake of bracken;
3. Avoid eating aged bracken: The content of wood fiber and protopterin in aged bracken is high, which is not conducive to digestion, and is easy to cause toxic accumulation, which is not good for health. It is recommended to eat tender stems and leaves;
4. Taboo population: people with spleen and stomach weakness, diarrhea and allergies. , should not eat bracken. Because Pteridium aquilinum is cool and high in cellulose, it may aggravate the symptoms of spleen and stomach deficiency and diarrhea after eating, while allergic people will cause allergic reactions and induce itching and redness of the skin.
