Is it more nutritious to eat freshwater fish or saltwater fish?
Experts will answer the question of whether eating saltwater fish or freshwater fish is more nutritious in this article.
According to Associate Professor Dr. Nguyen Duy Thinh - former staff of Hanoi University of Science and Technology, eating fish regularly is very good for health. Compared to protein and fat from pork and beef, fish is easier to digest and contains many valuable minerals that meat does not have or has less of.
People living in coastal areas often consume a lot of saltwater fish, while people living far from the sea mainly eat freshwater fish. The nutritional values of these two types are generally similar, but saltwater fish have a higher energy content.
Among freshwater fish, catfish and basa provide the most energy (1,245-1,700 kcal/kg). Among saltwater fish, tuna, mackerel and herring are the most energy-rich (1,500-2,300 kcal/kg).

Nowadays, due to environmental pollution and farming methods, saltwater fish tend to be safer than freshwater fish. Freshwater fish have a risk of heavy metal residues and antibiotics in their feed, so if you have access to safe marine fish, you should prioritize consuming more of them.
However, people with allergies or who are susceptible to food poisoning should be careful with certain types of seafood such as squid and tuna, as they may contain compounds that can easily cause adverse reactions.
It is important to maintain a varied diet. If there is a safe source of freshwater fish, eating it regularly is also very beneficial for health. Nutritionists recommend adding a variety of foods to ensure adequate nutrition and make meals more delicious./.
