Is bracken whole body poisonous or carcinogenic? For the health of your family, don’t forget these 2 steps before eating

Spring is blooming. It is the season when bracken is on the market. Many people love the fresh and tender texture of bracken. However, recently there is a saying that eating too much bracken will cause cancer and cause panic. So, does bracken really contain What about carcinogens? Can I really get cancer if I eat too much? Today, Xiao Ai will give you a good explanation.

Bracken is a wild vegetable commonly found in the countryside. It is called the "king of wild vegetables" and "longevity vegetables". The main edible part is the unexpanded young leaf buds . Bracken contains carotene, vitamins, potassium, calcium, amino acids and other nutrients. The treated bracken has a refreshing taste and rich nutrients. It is a delicacy on the table of ordinary people.

Bracken contains 2b carcinogens

In recent years, there have been a lot of rumors that bracken is carcinogenic, which discourages some bracken lovers from bracken. Studies have found that protopteridin contained in Pteridium aquilinum is a 2B carcinogen . Among them, the content of rhizome of Pteridium aquilinum is the highest, followed by leaves. Animal experiments show that Pteridium aquilinum is related to a variety of cancers such as stomach cancer, intestinal cancer, and breast cancer. So, is bracken really uneatable? it's not true.

Huang Ke, a professor in the Department of Vegetables, College of Horticulture and Landscape Architecture, Hunan Agricultural University, said: The risk of bracken is related to the intake. On the one hand, bracken has a very low content of protoporphyrin, which is contained in the dry matter of bracken. Only 0.1%-0.6%; on the other hand, after repeated washing of Pteridium aquilinum, the content of progonoside will be greatly reduced. In other words, after eating 0.5-3.5㎏ bracken every day for 20 years, it may cause cancer. However, in real life, this situation is almost impossible to exist. Therefore, when the bracken is on the market, as long as is properly processed and the intake of is controlled, it is a good idea to try it.

Before eating bracken, washes repeatedly with clean water,Blanch the water once, and then stir-fry , which can greatly reduce the content of harmful substances in the bracken. If you want to eat cold bracken, you can wash the bracken before eating, then blanch it in boiling water, and then cut it for consumption.

Bracken can be eaten cold and fried, and it can also be made into bracken root powder . Fern root powder is extracted from the starch in the rhizome of the fern, which is made after washing, drying and grinding the root of the fern. Like bracken, bracken root powder is also edible, and its carcinogenic risk can be effectively reduced by strictly controlling the intake.

Be careful when eating vegetables

In daily life, in addition to the bracken before eating, you should pay more attention to the consumption of toon, daylily and peas.

• 1. Toon

Toon has a crisp taste and rich nutrition. Toon scrambled eggs and fried toon are all rare delicacies. However, because the content of nitrate and nitrite in toon is higher than that of ordinary vegetables, some people say that toon can cause cancer.

First of all, it needs to be clear that any carcinogen that does not talk about the dose is a rogue. Studies have shown that the content of nitrite in toona sinensis is very low, far from reaching the carcinogenic dose. As long as you blanch it before eating, or eat buds but not leaves, and do not eat toon overnight, and eat in moderation, it will not harm your health.

• 2. Daylily

Often eat daylily, which can stop bleeding and reduce inflammation, improve eyesight and beauty, clearing heat and dampness , but it is dangerous to eat it wrong.Both fresh day lily and dried day lily contain a certain amount of colchicine.

After colchicine is digested in the stomach and intestines, it will form highly toxic dicolchicine. According to research, will be poisoned by consuming 3mg of colchicine, and consuming 20mg of colchicine will be fatal.

Therefore, if you eat day lily, you should pay attention to it. If it is fresh day lily, you should remove the stamens with the highest colchicine content.

If it is sun-dried day lily, the content of colchicine has been greatly reduced after dehydration and drying, so you can eat it with confidence, but remember not to eat too much.

• 3. Beans

Beans are not cooked, and they will cause nausea and vomiting after being eaten. Studies have shown that raw carob contains saponins and plant lectins, which can stimulate the gastrointestinal mucosa and cause gastrointestinal discomfort. Therefore, the beans must be fried thoroughly and cannot be eaten raw to avoid the risk of poisoning. In addition, try to choose more tender beans, because the older the carob, the more toxins.

Most vegetables are rich in various nutrients necessary for the human body. Eating more is good for the body, but the premise is to pay attention to food safety. Before consuming any vegetables, we must fully understand the correct way of eating, and at the same time adhere to the principle of "eating in moderation", with food diversification as the ultimate goal, and do not eat a single food in large quantities for a long time. #清风计划# #谣零零计划# #人人足球仁健康#
