In winter, fish head has become a hot item on people's table. Especially in restaurants, fish head soup, fish head casserole and fish head hotpot 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 heads are the places where toxins gather the most, and eating more is not good for the 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 for cleaning and softening blood vessels, lowering blood lipids, strengthening the brain and delaying aging. The content of DHA and EPA in fish oil is higher than that 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 a very important detoxification organ, which is also an important reason why people have to remove gills when eating fish. Under normal circumstances, there will be no toxin in the fish head, so it is safe to eat the fish head. However, due to the deterioration of the overall environment in recent years, the water area and ecological plant chain are polluted, and some farmers add chemicals to the feed, which is in a certain degree.
To a certain extent, harmful substances in fish will increase and be difficult to discharge, which 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. In addition, 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 which can be easily absorbed by human body, so it is also rich in nutrition.
In addition, there are a lot of parasites in the fish head, so you must 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" do a lot of harm. Take the chicken as an example. As the folk saying goes, it's been ten years of arsenic competition. This means that the older the chicken, the more toxic the head of the chicken is. From the modern medical point of view, the reason is that chickens will eat substances containing harmful heavy metals during pecking. These heavy metals are mainly stored in brain tissues. The older the chickens are, the more they are stored and the stronger their toxicity is. While enjoying the delicious chicken head, consumers also ingest heavy metal poisons. If they eat too much, they may cause toxic reactions. 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.
