Are wild fish healthy?

In the past, although many families usually lived in poverty, they cooked a dish with fish during the Chinese New Year. Not only does it mean more than a year, but it also means that the fish is rich in nutrition. Relevant research shows that people who eat fish once a week sleep better and have higher intelligence than those who seldom eat fish or don't eat fish at ordinary times. This is because it contains some ingredients, which can help regulate sleep disorders and maintain the functions of the human nervous system and brain nerves. Therefore, eating fish often is very helpful for the brain development of minors and the prevention of memory loss in middle-aged and elderly people. Besides, it contains a low amount of fat, so people who are afraid of getting fat often eat it to prevent obesity. Eating it also helps to soften blood vessels and prevent cardiovascular diseases. Although eating fish every week has a good sleep and high IQ, these two common fish should be eaten carefully, which is toxic or harmful to the body and even fatal. 1. Big Fish When we choose fish, we usually choose bigger fish. We think there are more such fish. Generally, big fish have these two situations. One is in a relatively high position in the biological chain. Such fish can usually eat more small fish and shrimp, so they accumulate more harmful substances in their bodies. If it's toxic, it's bad for your health. The other is very old fish. Although this kind of fish has a lot of meat, its meat quality is not very fresh. The longer it lives in water, the greater the possibility of pollution. So try not to choose fish that are too big to eat. 2. Wild Fish Some people have a hobby of fishing. If they think the fish on the market are not fresh, they will choose to catch wild fish by themselves. But in fact, the waters where wild fish live are not necessarily clean and pollution-free. The fatter the fish, the more pollutants such as heavy metals it contains. Although all wild fish are not necessarily poisonous, it is best not to eat wild fish at will. In addition, if you want to refrigerate the fish you bought, try not to exceed five hours, because the longer you refrigerate, the less fresh the fish will be. In the process of handling fish, special attention should be paid to cleaning the digestive tract, because the food residue inside contains a lot of bacteria and toxins, and it will be better to clean it before eating.
