In winter, fish head has become a popular item on people's table. Especially in restaurants, fish head soup, fish head casserole and fish head hot pot have become dishes with high click-through rate. However, there is also a popular saying that fish heads should not be eaten more. The reason is that fish head is the place where toxins gather the most, and eating more is not good for human body. What is the truth?
Modern scientific research has found that there are two kinds of unsaturated fatty acids in fish, namely docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). These two unsaturated fatty acids are very beneficial to clean and soften blood vessels, reduce blood lipids, strengthen the brain and delay aging. The contents of DHA and EPA in fish oil are higher than those in fish, and fish oil is relatively concentrated in fish head. In this sense, eating more fish heads is really beneficial to people's health.
Experts also pointed out that gills are not only the respiratory organs of fish, but also very important detoxification organs, which is also an important reason why people have to remove gills when eating fish. Under normal circumstances, there is no toxin in fish head, so it is safe to eat fish head. However, due to the deterioration of the overall environment in recent years, the waters and ecological plant chains have been polluted, and some farmers have added chemicals to their feed to a certain extent.
To a certain extent, harmful substances in fish will increase, which is difficult to be discharged and may accumulate in the fish head. In order to ensure food safety, consumers should try to buy fresh fish and other aquatic products from regular and supervised markets. Besides, they should eat fish heads in regular restaurants and try not to order fish heads from roadside stalls.
It is also important to point out here that eating more fish heads is beneficial to human health, but it does not mean eating only fish heads without eating fish. Fish is not only rich in protein, but also rich in amino acids easily absorbed by human body, so it is also rich in nutrition.
In addition, there are many parasites in the fish head, so be sure to cook the fish head, and don't be greedy, especially when eating hot pot.
Many people like to eat chicken heads, duck heads, goose heads and fish heads. Indeed, the heads of these fish and poultry are delicious and have high nutritional value. However, these "heads" have caused a lot of harm. Take the chicken as an example. As the saying goes, ten years of arsenic competition. This means that the older the chicken, the more toxic the head of the chicken is. From the point of view of modern medicine, the reason is that chickens will eat substances containing harmful heavy metals when pecking. These heavy metals are mainly stored in brain tissue. The older the chicken, the more it is stored, and the more toxic it is. While enjoying the delicious chicken head, consumers also ingested heavy metal poisons. If they eat too much, it may cause poisoning reaction. Therefore, it is not advisable to eat more chicken heads. Duck head and goose head should not be eaten more, and the reason is similar.
