Why is it said that one-third of the salmon on the market comes from the Qinghai-Tibet Plateau?

Many people’s news feeds have been flooded with the news that “one-third of the salmon in the Chinese market comes from the Qinghai-Tibet Plateau.” Salmon is supposed to be "Atlantic salmon", which is a kind of sea fish that can be eaten raw. The "salmon" reported as coming from the Qinghai-Tibet Plateau is actually rainbow trout, which grows in fresh water. Because freshwater fish can easily carry parasites, they cannot be eaten raw. Immediately, many self-media tweets told consumers how to distinguish between the two, such as salmon having a thinner texture and rainbow trout having thicker lines. But in fact, as an ordinary consumer, it is difficult to effectively distinguish the difference between the two.

In fact, in terms of nutrition alone, salmon and rainbow trout are almost the same. Li Dongmei, a nutritionist at Beijing Anzhen Hospital, said: "The protein content of the two fishes is similar and both are rich in unsaturated fatty acids. As a saltwater fish, salmon only has slightly higher trace elements than rainbow trout, such as iodine, selenium, manganese, etc. In other aspects There is no big difference."

Li Dongmei explained that generally salmon can be eaten raw after being deep-frozen. High temperature can kill parasites, so rainbow trout should choose cooked food. For consumers who have difficulty distinguishing between real and fake salmon, cooked food is the safest choice. Text/Wei Ge
