Does eating bracken really cause cancer?
It has been proved by scientific research that bracken does contain cancer-related substances, including phenyloxalic acid, fern lactam, flavanols, acoflavin and some substances similar to acoflavin. Too much intake of these substances will be harmful to health. Therefore, the expert told us that "it is true that eating bracken causes cancer", so she suggested that everyone should "not eat bracken as well".

In fact, these wild vegetables have existed for many years, and almost always accompany human beings. The vegetables that are common on people's tables have been selected by our ancestors countless times, which proves that they are edible. Why some wild vegetables have not become frequent visitors to our tables is also reasonable. Like bracken, our ancestors may not know that it can cause cancer, but we can definitely judge that it is not very suitable for long-term consumption. Therefore, it is not included in the vegetables we often eat. Therefore, we should not choose some so-called game foods at random according to our own judgment, which will bring new hidden dangers to our health.

Pteridium aquilinum contains some carcinogens and is preserved, so the probability of carcinogenesis is even greater. Now there are more fresh vegetables in winter in Northeast China. Therefore, it is recommended that you eat less preserved foods in winter, because preserved foods contain a lot of nitrite, which is very easy to generate ammonium nitrite when entering the body. Therefore, it is better to eat less.

When the so-called wild vegetables are definitely not just bracken, there are many dishes that people rarely see at ordinary times. Now there are restaurants to cater to people's demand for this kind of novelty-seeking, and there are many wild vegetables that people don't often eat, and the price is very high. Experts tell us that we should eat less such wild vegetables, or we should eat the vegetables closest to us, that is, the vegetables that can be planted artificially, so that we can at least grasp them. Many people choose to eat wild vegetables because they are early adopters. Second, they think wild vegetables are safer without spraying chemical fertilizers and pesticides. However, they don't know that it is impossible to prevent them, and wild vegetables also cause cancer.
