Which is the highest nutritional value of marine fish? Which is safer and better?

Fish is an indispensable delicacy on the table. The fillet is tender and smooth in taste and has high nutritional value. But many people often wonder which is better, sea fish or river fish. Which one should I eat? Let's talk about this topic with us today.

Which is the highest nutritional value of marine fish and river fish?

The different fishes in the growing waters are divided into marine fish and freshwater fish (that is, marine fish and river fish). In terms of nutritional value, there is no significant difference between them, and both contain 15% and 22% of high-quality protein. 1% to 10% fat (mostly composed of unsaturated fatty acids): it also contains a certain amount of vitamin A, vitamin D, vitamin B. And calcium, sodium, potassium, magnesium and other minerals.

As for what many friends say, "Marine fish contain more DHA", this is not the case. The contents of DHA and EPA in muscle and visceral fat of 5 species of marine fish (herring, belt fish, yellow croaker, Spanish mackerel, Pomfret) and 9 species of river fish (sea bass, forehead fish, Chinese Sturgeon, fish sperm, tilapia, Wuchang fish, carp and grass carp) were analyzed. It was found that the contents of DHA and EPA in marine fish were not higher than those in river fish. The content of DHA in sea bass was also very high. Therefore, the content of DHA has nothing to do with sea fish or river fish. It has something to do with the species of fish.

Of course, if you compare the details, marine fish may contain more nutrients, especially in the production of acid from minerals and unsaturated fats.

Second, which sea fish and river fish is safer?

Many people think that sea fish live in the sea. The blue sea and blue sky must be cleaner and safer to eat than the river fish. This is not absolute, with the development of industry, a lot of water bodies are polluted, the marine world is no exception, especially the water quality of offshore water cities is worrying. Of course, the chance of pollution in the deep sea is much less, and the quality of deep-sea fish is also much better.

Whether it is safe or not, the key depends on whether the culture environment meets the requirements. As long as it is not cultured in polluted water. The fish caught are generally safe. At present, the international popular food safety traceability system, so that every fish from birth, growth, to fishing, processing, until on the table are recorded, there is a complete supervision chain.

Whether it is sea fish or river fish, it all depends on your own taste and hobby. Eat whatever you like. Okay, so that's the end of today's story. Friends who like can follow Tuliu.com. I'll see you next time.
