Nowadays, people pay attention to a balanced diet, like seven points of vegetarian and three points of meat, and even have a special preference for vegetarian dishes, some friends even like to eat wild vegetables, such as bracken, but when they are eating, they brushed some popular science texts, saying that bracken is a cancer inducer, and instantly feel that the bracken in the mouth is not fragrant. So is bracken really carcinogenic?
Is bracken a delicious wild vegetable or a cancer inducer?
Bracken, also known as fist dish, cat's claw, fern dish, fern moss, pot lotus, dragon head dish, boxing dish, deer bracken, good taste, rich nutrition, and has high medicinal value, known as the "king of mountain vegetables". As a traditional green leafy ingredient in the mainland, bracken is a popular spring wild vegetable.
But the main reason why bracken causes cancer is because it contains a substance called "protofern", which has been found to increase the incidence of stomach cancer and esophageal cancer. This substance is most abundant in the shoot section. But it doesn't mean that eating bracken will cause cancer, and any claim that it leaves the portion and talks about toxicity alone is irresponsible. If you only eat bracken once in a while, the content of proto-tibetan glycosides is actually very low, and the human body has a self-regulating function, which can completely control the adverse effects of protoferns on the body. As long as it is not a long-term large amount of eating, it is fine.
Many people like to eat barbecue, pickles, high-fat, high-cholesterol foods, etc., which may cause cancer. But also you can use some small tricks, such as blanching with boiling water before eating, soaking for a period of time, changing the water several times during the period, the protofern that is easily soluble in water can be greatly reduced. In addition, adding a little vinegar when cooking can also make proferns more volatile. You can enjoy delicious bracken with peace of mind. In addition to bracken, there are also some vegetables to pay attention to.
Doctor: These vegetables should be eaten less, and the liver and kidneys are more carcinogenic

Before the news there have been children eating bitter gourd after the shock report, gourd has sweet gourd and bitter gourd, bitter gourd melon and sweet gourd melon shape is similar, but the melon abdomen is large and somewhat deformed, its taste is bitter and contains glycosidine toxins, this toxin is not easy to destroy and decompose when heated. Consumption of gourd melon with high content of gourd glucoside toxins can lead to poisoning, nausea, vomiting, abdominal pain, diarrhea, fever and other symptoms.
2) Fresh yellow cauliflower
Fresh broccoli contains colchicine, colchicine itself is not toxic, but after eating it will be oxidized in the body into a very toxic colchicine, light diarrhea and vomiting, heavy muscle weakness or even death, the harm is very large. Therefore, when eating fresh broccoli, you must first blanch it with hot water, and then soak it in water for 2-3 hours.
