Some friends around us like to call leeks. The leeks are pure natural and pollution-free. They are rich in protein, cellulose, vitamins, and minerals. The flavonoids are also anti-tumor, antioxidant, and anti-free radicals. The role. Well, let’s talk about today’s leeks that are really carcinogenic. Can we eat them?
In recent years, scientists at home and abroad have found that bracken has a certain carcinogenic effect. The reason why it causes cancer is because it contains a substance called "primordrin".
It is understood that the International Organization for Research on Cancer has classified bracken as "a plant that is possibly carcinogenic to humans." In the 1970s, researchers investigated the relationship between eating fern and suffering from esophageal cancer in the mountains of central Japan. They found that eating bracken in the residents there increased the incidence of esophageal cancer by 2.1 times for men and 3.7 times for women. In 1990, British scientists conducted a "case-control" study. The results also showed that eating bracken at a young age may increase the risk of subsequent gastric cancer. Similar studies have also been done in other parts of the world and the results are basically the same.

Appropriate cooking methods can reduce risks: Director Lu Bozhen said that bracken has a positive effect on health and a negative effect, but the opinions of experts at home and abroad are that if you do not like to eat bracken, then there is no It is necessary to try fresh, if you like this food, eat it occasionally, as long as it is not particularly frequent, the health hazard is not great. Xia Wenlong, a nutritionist at Tongde Hospital in Zhejiang Province, also believes that there is no problem as long as you eat properly.

As long as proper cooking methods are adopted, the content of “primary phosporin†in bracken can be reduced, and the risk of cancer can be reduced. "Porcine" is readily soluble in water. If the fern is fully saturated with water and replaced with fresh water before cooking, the fern arborin content in the fern will be reduced. In addition, “Pteridium phenidinium†is easily volatilized at room temperature and unstable under acidic or alkaline conditions. Therefore, if it can be cooked at a relatively high temperature, or a little vinegar is added during the cooking process, it can be destroyed. "Prigosporin" reduces the carcinogenic risk of bracken.
Although the leek can cause cancer, but as long as the food is not particularly frequent, soaked in water before soaking, high-temperature cooking, add a little vinegar in the cooking process, is also a good delicacy.
