Blanch bracken with boiling water before eating, then soak it in cold water to remove the odor, and you can eat it.

There is a protofern glycoside in the ingredients of bracken, which can cause cancer. Although there is clear scientific evidence that bracken causes cancer, it means "increasing the risk of cancer", not "eating it will cause cancer". The so-called "increased risk" refers to the increased possibility of illness. "conclusive evidence" means that "it will increase the risk" is affirmative, but as far as the carcinogenicity of bracken is concerned, it is different from "how much risk is increased". According to the epidemiological survey results in Japan1970s, eating bracken regularly increases the risk of esophageal cancer in men by 2. 1 times and in women by 3.7 times. As far as the proportion of increase is concerned, it is indeed very large, but considering that the risk of normal occurrence of esophageal cancer is not high, it is still a relatively small chance to increase it by two or three times. Moreover, this is an area where bracken is often eaten for a long time, and protopterin will also exist in the local drinking water. Risk is related to intake. If you really like its taste, taste it occasionally, and the risk is minimal.
