Wild vegetables are just at the right time, so don't let them eat fresh and dangerous food. It's about to enter the beginning of summer in the 24 solar terms. At this time, many crops are entering the peak growing season and gradually maturing, which is also a good time to eat wild vegetables. Recently, reporters have noticed that many people have posted pictures of wild vegetables dug by the roadside on social media platforms, and Weibo topics related to wild vegetables have even made it to the hot search list. However, many netizens also expressed that although wild vegetables are rich in nutrients, some people can cause a significant burden on their bodies if they eat them; Some wild vegetables are not suitable for consumption due to their bitter taste; At the same time, some wild vegetables may also accumulate pollutants such as lead and should not be eaten too much. So, in daily life, how should we distinguish different wild vegetables? Will wild vegetables be contaminated? How to scientifically and healthily consume wild vegetables? The reporter interviewed relevant experts with these questions. Before picking, one should first familiarize oneself with the characteristics of wild vegetables. Zhang Baohai, a senior specialty expert at the Vegetable Research Institute of the Beijing Academy of Agriculture and Forestry, stated in an interview with reporters that there are many types of wild vegetables that can be consumed by people in daily life. Taking herbaceous wild vegetables as an example, wild vegetables such as shepherd's purse, dandelion, bitter dish, prickly greens, and small root garlic are more common; woody wild vegetables such as Chinese toon, elm, magnolia sprouts, willow sprouts, and poplar suspension can also be consumed by people, "said Zhang Baohai. So, how can we distinguish different types of wild vegetables? Zhang Baohai stated that first, it is necessary to master some typical characteristics of wild vegetables, such as shepherd's purse having small white flowers and bearing very small triangular fruits; The flowers of a dandelion are light yellow, and after pulling off its leaves, white juice will flow out. Secondly, it is important to familiarize yourself with various wild vegetables under the guidance of professionals or experienced individuals. Familiarizing and identifying various wild vegetables requires the guidance of professionals and multiple practices, "Zhang Baohai further said. Some mobile apps that can recognize plant species can also assist in identifying wild vegetables while clearly capturing their unique features. However, there is a certain probability that these apps will report errors, so they cannot be fully trusted. Digging wild vegetables requires avoiding polluted areas. Some people believe that wild vegetables are healthy and edible. Is this really the case? Zhang Baohai stated that when collecting wild vegetables, one should consider their growth environment. In fact, some places' wild vegetables are not suitable for people to pick and eat. Wild vegetables grown in areas with high traffic may accumulate heavy metal elements such as lead; some wild vegetables grown in artificial forests may have residual pesticides, "he said. At the same time, Zhang Baohai said that when picking wild vegetables, it is also necessary to avoid nearby areas such as factories, sewage, roads, and landfills, to avoid harm to the body caused by accidental consumption of contaminated wild vegetables. I personally do not recommend that you dig wild vegetables in the park or on the roadside during outdoor outings, as it can damage the environment and also potentially accidentally pick toxic wild vegetables. It is best for you to purchase wild vegetables through legitimate channels. If you want to pick wild vegetables yourself but are not very familiar with their characteristics, it is recommended to pick them under the guidance of a professional, "said Zhang Baohai. For some herbaceous wild vegetables, do not uproot them when picking, as this way they can continue to grow; Do not over pick to avoid causing ecological damage
