Can you eat it? About bracken
First, the historical origin of bracken
From ancient times to the present, people have special feelings for wild vegetables, which have been regarded as famine relief in famine years in all dynasties. Known as the "king of wild vegetables", bracken (also known as fist dish) has a longer history.
"The Book of Songs-Zhao Nan" inclines Nanshan and picks its ferns.
"This is the earliest evidence that bracken has entered the vegetable field. "Er Ya Yi" Ferns are like children's fists, purple and fat.
The poet Bai Juyi said that bracken has always been used as children's 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 sense of sublimity and seclusion.
Second, the nutritional value of bracken
Pteridium aquilinum is rich in protein, cellulose, vitamins and minerals needed by human body, and has the functions of refreshing, degreasing, promoting 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 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 flavonoids in it also have anti-tumor, anti-oxidation and anti-free radical effects. However, bracken also contains a substance called protopterin, which is considered to be a carcinogen to human beings.
So, can wild bracken in rural mountains be eaten? Of course you can eat, just pay attention to the way you eat.
(1) It is not advisable to eat bracken in large quantities frequently.
Bracken does contain carcinogens, but it doesn't mean that eating bracken will definitely lead to cancer. 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 only a seasonal wild vegetable, and it is completely okay 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 in it, which can also reduce the bitterness and earthy taste of some bracken itself.
(3) Protopterin belongs to Class 2B carcinogen.
Protopterin is listed as a class 2B carcinogen by the World Cancer Organization. The so-called class 2B carcinogen is a kind of carcinogen classification, 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 mountains 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's best to put some salt or alkali in it when blanching, which can also reduce the bitterness and earthy smell of bracken itself.

Efficacy, function and taboo of bracken
Efficacy, Function and Contraindications of Pteridium aquilinum is a familiar wild vegetable variety. Pteridium aquilinum is widely distributed in China, so there are many different varieties. Bracken is one of them. Let's learn about the efficacy, function and contraindications of bracken.
Efficacy, Function and Taboo of Pteridium aquilinum 1
First, does bracken cause cancer?
Pteridium aquilinum can cause cancer. It contains some substances only found in cancer. These substances exist in roots, stems and leaves, but these substances are related to the consumption. If you eat them once or twice occasionally, you won't get cancer, but if you eat them for a long time, it 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 resolve phlegm accumulation; Young leaves can be used as vegetables.
General bracken often tastes bitter and astringent. It should be boiled first, then washed in water and eaten after three or four days.
Pteridium don't need to be boiled, just remove the old ones and wash them.
You can fry it directly.
Fried bracken, it is best to use vegetable oil. When the oil is hot, stir fry, add salt, ginger, pepper and lobster sauce. Before frying, add garlic slices and monosodium glutamate and mix well. A plate of delicious bracken is ready.
Need to remind: water bracken should be fried as soon as it is washed, and the taste is fresh and tender with a little water.
Third, the efficacy and role of bracken
1 Promote blood flow
Because some people's blood flow speed is relatively slow, and they usually don't pay attention to their own 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 to effectively cure some people's blood diseases through some targeted foods.
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 quickly detoxify to promote the discharge of toxins from the body.
In ancient times, bracken was a very popular food. Some people used bracken to promote the excretion of toxins in the body, and now it is actually the same.
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 everywhere, it is recommended to take some bracken.
In this case, taking bracken can obviously help people stop bleeding quickly and relieve pain.
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 play the most basic health care role for 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 eating a certain amount. 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. Proper and moderate consumption will generally not cause adverse effects on the body.
However, bracken contains protopterin and other toxic substances, so there are certain taboos when eating bracken.
1. It is forbidden to eat raw bracken: before eating bracken, it is recommended to soak it in alkaline water, then blanch it in 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 lead to the accumulation of protopterin 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. It is forbidden to eat 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 toxin accumulation, which is not good for health. It is recommended to eat tender stems and leaves;
4. Taboo population: For people with spleen and stomach deficiency, diarrhea, allergies, etc. It is not advisable to eat bracken. Because bracken is cool and high in cellulose, it may aggravate the symptoms of spleen and stomach weakness and diarrhea after eating, while allergic people will cause allergic reactions and induce itching and redness of the skin.
