Introduction
Eating bracken fern may potentially cause cancer, as the young shoots commonly consumed tend to have higher levels of carcinogens compared to the rhizomes. Bracken fern contains ptaquiloside, which not only can damage DNA genetic material but also may irritate the liver, stomach, lungs, and esophagus, thereby increasing the risk of cancer. Therefore, it is best to treat fresh bracken fern with wood ash or alkaline water before consumption.
Generally speaking, whether bracken fern consumption can cause cancer mainly depends on the amount consumed and how it is prepared. If any discomfort occurs, it is advisable to seek medical attention promptly. The details are as follows:
1. Not likely
Bracken fern is rich in vitamins and minerals, offering certain nutritional benefits. It contains a substance called ptaquiloside, which has shown potential carcinogenicity in animal studies. However, for humans, the cancer risk associated with ptaquiloside depends on the level of intake. When consumed in moderation as part of a regular diet—especially if the bracken fern is thoroughly cooked—the levels of ptaquiloside are significantly reduced, making it generally non-carcinogenic.
2. Possible
If large quantities of improperly processed bracken fern are consumed regularly over a long period, the higher levels of ptaquiloside may increase the risk of developing cancer, in which case it could be carcinogenic.
To avoid unnecessary harm to the body, it is recommended to consult a healthcare professional. Maintaining a balanced diet, getting adequate rest, and engaging in appropriate physical activity in daily life can promote overall health and reduce cancer risk.
