Is fish nutritious?

As the name implies, the biggest difference between river fish and sea fish lies in the growing environment. Professor Wang told reporters that in fact, strictly speaking, river fish should be called freshwater fish, and the common ones are carp, crucian carp, grass carp, silver carp, Wuchang fish, tilapia and eel. Marine fish include hairtail, tuna, large yellow croaker, small yellow croaker, Spanish mackerel, salmon and turbot.

He said that no matter whether it is freshwater fish or marine fish, their nutritional components are basically the same, and their total nutritional value is very high. First of all, fish is rich in protein, and the quantity and proportion of essential amino acids are most suitable for human needs, which is a good source for human to ingest protein. Secondly, fish contains less fat and is mostly composed of unsaturated fatty acids. The absorption rate of human body can reach 95%, which has the functions of lowering cholesterol and preventing cardiovascular and cerebrovascular diseases. Thirdly, fish is rich in minerals such as iron, phosphorus and calcium. Fish liver contains a lot of vitamin A and vitamin D.

In addition, the muscle fiber of fish is very short and has high water content, so the meat is tender and easier to absorb than the meat of livestock and poultry. Professor Wang pointed out that fish is more beneficial to human health than food with high nutritional value but not easy to absorb.
