Does eating bracken cause cancer, and does eating bracken cause cancer

The evidence that protofern glycosides cause cancer is not direct, but if consumed excessively over a long period of time, the incidence of gastric and esophageal cancers may increase greatly in sensitive groups.

The fern (bracken is its shoot) is one of the most widely distributed plants in the world, and in many places its shoots are treated as vegetables, and starch is also extracted from the roots. Bracken, also known as longevity vegetables, is a wild plant known as the "king of mountain vegetables". Each gram of bracken contains mg of carotene, 35mg of vitamin C and a variety of minerals.

Traditional Chinese medicine believes that bracken is sweet in taste, cold in nature, has the effect of clearing heat, relieving dampness and reducing swelling, calming the nerves, invigorating blood and relieving pain, and can be used for fever, dysentery, jaundice, etc.

The "protofernin" in bracken may be the culprit of carcinogenesis, and experiments have found that protofernin can also react with amino acids and destroy genetic material DNA. Protofern glycosides are found in all parts of the fern, and the bracken eaten by humans is more abundant in the young parts of the fern.

However, fresh bracken is bitter and astringent, and most people generally treat fresh bracken with plant ash, alkaline water or blanching before eating. However, this treatment only reduces the content of proterteosides, not completely eliminates them.

Experts remind: wild meat, wild vegetables, which are relatively "far away" from us, have not become the main dishes on the table after thousands of years of choice, and try to eat as little as possible; It is best to focus on food that is relatively "close" to us in our daily diet, and we should not try all kinds of game for the purpose of trying new ones.

Bracken contains certain carcinogenic ingredients, mainly because if it is not cooked, it will cause hematopoietic dysfunction substances, and long-term eating will cause carcinogenesis, but if the bracken is cooked thoroughly, its nutritional value is still very high, which can effectively improve constipation and promote intestinal peristalsis.

Can cause cancer. Bracken not only contains benzoxalic acid, fern lactam, flavine alcohols, quercetin compounds, but also fern iruloside, a strong carcinogen!

Animal feeding experiments have shown that bracken can induce gastric cancer, bowel cancer, breast cancer, bladder cancer, leukemia and so on in rats.

Carcinogenic tests of cooked bracken have shown that even processed bracken can induce cancer. The cooking process has not been able to destroy the molecular structure of carcinogens in bracken, and even some other new compounds that may cause cancer have been discovered.

Other carcinogenic foods.

1. Sprout potatoes.

Sprouted potatoes produce large amounts of solanine, which can be poisoned by humans after eating.

2. Unfried green beans.

Unfried green beans contain saponins, which can be poisoned by humans.

3. Green tomatoes.

Unripe tomatoes contain alkaloids, which can cause poisoning when consumed by humans.

4. Rotten ginger.

Rotten ginger produces a carcinogen called safrole, which can induce liver cancer and esophageal cancer.

5. Fresh lentils.

Fresh lentils contain saponins and alkaloids, which are toxic but dissolve when heated.

Eat more, I read a book, so try to eat less.

It has been scientifically proven that bracken does contain cancer-related substances, including benzoxalic acid, fern lactam, flavonols, quercetin and some substances similar to quercetin, which can be harmful to the body if consumed in excess. Therefore, experts tell us that "it is true that eating bracken causes cancer," so she advises everyone to "not eat bracken as well".

In fact, these wild vegetables have existed for many years, almost all the time accompanied by human beings, those common vegetables on people's tables are after our ancestors countless choices, proved to be edible, and why some wild vegetables have not become frequent guests on our table, that is also a certain reason. Like bracken, our ancestors may not have known that it can cause cancer, but it can certainly be judged that it is not very suitable for long-term consumption. Therefore, it is not included in the vegetables we often eat, so don't choose some so-called game foods according to your own judgment, which will bring new hidden dangers to our health.

Bracken itself contains some carcinogenic substances plus pickled, so the probability of carcinogenicity is even greater, and now there are more fresh vegetables in the winter in the Northeast, so it is recommended that everyone should eat less pickled food in winter, because pickled foods will contain a large amount of nitrite, and it is very easy to generate ammonium nitrite into the body, so it is better to eat less.

When the so-called wild vegetables are definitely not only bracken, there are many dishes that people usually rarely see, and now there are special restaurants to cater to people's needs for this kind of hunting, what wild vegetable restaurant to open, find a lot of wild vegetables that people do not often eat, and ** is very high, experts tell us that such wild vegetables should be eaten less, or to eat the vegetables closest to us, that is, vegetables that can be artificially grown, so that we can at least grasp. Many people choose to eat wild vegetables because they try it first, and they think that wild vegetables will not be sprinkled with chemical fertilizers and pesticides, which is safer, but they don't know that they can't prevent it, and wild vegetables also cause cancer.

There is currently no scientific evidence that bracken itself causes cancer. Bracken is a fern that is rich in vitamins B, selenium, potassium and other nutrients, and has the effects of clearing heat, diuretic, and lowering blood pressure.

However, wild varieties of bracken contain certain toxic ingredients such as cold condensin and solanine, which can lead to food poisoning if not properly handled or processed. In addition, if there is a lack of hygiene measures during storage, it is also susceptible to bacterial contamination and cause problems.

Therefore, to eat bracken safely, it is recommended to choose regular channels to buy, wash thoroughly and blanch with boiling water, avoid eating wild bracken or bracken that has not been adequately processed, and pay attention to changes in personal taste and health conditions.

The substances associated with cancer contained in bracken are benzoxalic acid, fern lactam, flavonols, quercetin, and some substances similar to quercetin. These carcinogens are most abundant in the rhizomes of bracken, followed by the leaves. x0d x0a According to the carcinogenic experiments of bracken in many countries around the world, bracken can induce bowel cancer, breast cancer, bladder cancer, leukemia and so on in rats.

1. Bracken does contain certain carcinogenic ingredients, mainly because bracken that is not fully cooked contains certain substances that cause hematopoietic dysfunction, and eating raw bracken for a long time can indeed lead to cancer.

2. But as long as the bracken is fully cooked and eaten, it will not cause cancer.

3. The nutritional value of bracken is very high, and the carotene and protein content in it are very high, which can not only promote metabolism, but also effectively improve vision, and the crude fiber in it can also promote intestinal peristalsis and improve constipation.

Consumption of bracken does cause cancer。People who eat bracken often are prone to stomach cancer, esophageal cancer and bowel cancer, which are highly carcinogenic. Bracken not only contains benzoxalic acid, fern lactamide, flavine alcohols, quercetin compounds, but also fern iruloside, a strong carcinogen!

Experimental data also revealed that these carcinogens were most abundant in the rhizomes of bracken, followed by those in the leaves.

The ways in which bracken causes cancer are:

Through hydrolysis, a highly carcinogenic dienecanone compound is formed in which there is no absolutely safe dose.

It has an effect after years of consumption.

The carcinogenic mechanism of bracken protofern glycosides is through hydrolysis to form a highly carcinogenic dieneone, which can cause the DNA structure to become unstable and break down, thereby triggering a series of abnormal cellular reactions, and eventually leading to the production of cell mutations. In short, protofertinosides belong to genotoxic carcinogens , that is, they alter genetic material such as DNA, causing carcinogenesis. One of the important differences between genotoxic carcinogens and general carcinogens such as arsenic is:

There is no action threshold. In other words, there is no such thing as a safe dose – no matter how small the dose is ingested, it is theoretically carcinogenic. There is no absolutely safe dose for eating bracken, but protoferticoside, like other carcinogens, has an association between dose and carcinogenic effects, and the probability of cancer increases with increasing dose and frequency of exposure.

Bracken causes cancer is often the result of a combination of factors over the years: in addition to the dose and frequency of exposure to carcinogens, many other details such as individual health status, genetic factors, living habits, and living environment play an important role in the formation of cancer.
