Preface
Bracken is known as the "king of mountain vegetables", it is said that it was the main food of vegetarian dinosaurs during the dinosaur period 100 million years ago, because of its unique taste favored by people, but also a symbol of dietary diversity, bracken root powder is also a very important part of the many uses of bracken.
In August 2014, the Ya'an People's Government reported that a local family of five had been hospitalized for collective poisoning after eating wild bracken, and that they had been in many hospitals in serious condition.
Historical evaluation
For the first time in the history of the mainland, it was mentioned that there was a record of bracken in ancient documents such as the Book of Songs, which had high medicinal value in the eyes of ancient medical scientists, and now has become an indispensable delicacy on the table of ordinary people, but with the passage of time, scientists have found that bracken contains carcinogens strawberry calcium and fern acid, and long-term intake will cause adverse effects on human health.
So the question is, since there are poisonous substances in bracken, why do people eat it for thousands of years and are fine? Today, let's find out whether bracken is poisonous or not, first of all, let's take a look at how famous people in history evaluate bracken.
During the Tang Dynasty, the medicine king Sun Simiao commented on bracken, he said that "long-term food becomes a fist", which means that if you use the dish for a long time, it will bring disadvantages to the body, and Li Shizhen, the god of medicine in the Ming Dynasty, also mentioned in the Compendium of Materia Medica, "long-term food makes the eyes dark, nasal congestion, hair falling" and many other side effects.
carcinogen
And through the descriptions of these two pharmacists, it can be seen that eating a large amount of bracken is indeed harmful to people's health, but from their words, it can only be found that eating bracken can only cause symptoms such as nasal congestion and bloating, so what is carcinogenic?
Bracken is very widely distributed, exists in the warm and tropical areas of the world, bracken in the mainland is also in the north of the Yangtze River basin and subtropical areas, bracken can grow about 20 cm above the ground, the newly grown parietal leaf is not fully expanded, will show the appearance of a lollipop eaten by children, and this is the best picking period.
And it is not only popular in the mainland, such as South Korea, Japan and some European countries, it is also very fond of bracken, and it is even regarded as one of the traditional cuisines.
Although bracken is delicious, it has been found that bracken contains 3 types of carcinogenic progenogenic fernin substances, and the definition of 3 categories is that the carcinogenic effect on animals is limited or the evidence is insufficient, but the conclusion that it is harmful to humans cannot be fully confirmed, but it is true that bracken contains carcinogens.
Some people heard that this thing contained carcinogens, and they began to stay away, even if they loved to eat it before, they turned a blind eye to it, and some people even wondered why the elderly in the family had eaten this thing since childhood, why did they suddenly say that they couldn't eat it.
In fact, like in our daily life, alcoholic beverages, betel nuts, cigarettes and other pickled products have been identified as first-class carcinogens many years ago, but there are still many people who can't live without this thing, and not everyone will get cancer if they eat these things.
Therefore, eating a few bites of bracken, or trying bracken delicacies, will get cancer, this statement is not reasonable, so eating some bracken properly will not be more harmful.
How to eat bracken correctly
Bracken it is the most important is the original bracken content position, this place can be eaten after processing, it exists in the tender tip of bracken, if you want to eat bracken with confidence, you must first remove the tender tip, of course, in order to ensure the taste, you can remove some old places of bracken roots.
This is the first step, the next step is to clean, after cleaning there is the most critical step, that is, you need to put the washed bracken into boiling water for blanching, because it contains carcinogens that are more soluble in water, if you are not at ease after cleaning, you can use boiling water to blanch, which can also effectively remove the carcinogens remaining in it.
After blanching, put it in cold water and wash it, so that you can tear off the skin until the bracken is washed and there is no slippery or astringent, and then soak it in water for two days, you need to change the water in the middle, so that you can maintain the freshness of the bracken well, and then control the water, you can make it into a delicacy.
Bracken is a spring food with a high edible nutritional value, containing about 1.6 grams of protein, crude fiber, fat and carbohydrates, as well as some trace amounts of calcium, iron, phosphorus and carotene.
Therefore, as long as the bracken is handled properly, it is still edible, and it also has the value of "natural medicine" for the body, so we can't completely "give up" the bracken just for some reasons, and the bracken itself still has good value, as long as we don't eat a lot of it, it can still be eaten.
Now fern root powder is sold for dozens of yuan a catty, and it has become a special product in some southern areas.
Wild vegetables have a long history of eating in the mainland, in ancient times often used as famine food, with the improvement of people's living standards now, wild vegetables have also become a common ingredient, its status is not inferior to vegetables, in fact, some of the wild vegetables are still very delicious and have high nutritional value and medicinal value.
In recent years, they have become more and more popular with the public, and many people will go up to the mountains to dig wild vegetables every year, some people will take them to the city to sell, and some will take them back to eat with family and friends.
Those wild vegetables can't be eaten
Purslane this plant will show red and yellow flowers when it blooms, it looks like a beautiful landscape from afar, young people may rarely know it, children have used it as a toy to play with a long time ago, especially some thrifty old people, like to dig some purslane to take home to eat.
Wash it and dry it to make a dried purslane, used to make dumplings or buns, in the hot summer, people eat some frozen purslane in moderation can play a role in clearing heat and detoxifying, but it should be noted that although it has a certain nutritional value, but do not eat too much at a time.
Because it contains a toxin, long-term intake will lead to the accumulation of toxins in the body, increasing the burden of liver operation and decomposition, and affecting physical health in the long run.
Wild Serina
As we all know, celery, whether it is a root or a leaf, can be made into a delicacy for everyone to enjoy, like the celery we grow ourselves can be eaten with confidence, but the wild celery that grows in the field is inedible because it has a scary name - poisonous cabbage.
This wild vegetable grows in places with high temperature, heavy rainfall and relatively humidity, and its leaves look like the celery we usually eat, which will smell very bad when it blooms, and wild celery itself is also highly toxic.
The flower toxicity it grows is the greatest, and symptoms such as nausea, vomiting, numbness in the limbs will occur after ingestion, and in severe cases, it can cause shock or even death, so everyone must distinguish between wild celery and celery, and must not eat it by mistake!
Of course, there are many wild vegetables that cannot be eaten in daily life, not only the two mentioned above, such as Qucai Niangzi, Red Phoenix Cabbage, etc., which are not edible, and will bring more or less harm to the human body after eating.
The reason why wild vegetables are called wild vegetables, one of the most critical points is that no one cares, it will grow on its own, so the general growth environment of wild vegetables will not be very up to standard, like some wild vegetables growing on the edge of farmland, we still have to be cautious to eat.
Because it may have pesticide residue problems, and some chemical processing plants or wild vegetables growing on the edge of wastewater, you should not take them home.
You must remember not to eat wild vegetables you don't know casually, so as not to be poisoned, there are many ways to eat wild vegetables, and how to eat them should be determined according to different ways of eating different wild vegetables, but before eating, we must deal with it well, and remove some inedible parts.
