Trap 3: check whether the body is fake or not, and it is true to cheat to buy fish oil. The next day, the reporter chose a one-day tour that claimed to be Hainan Professional International Travel Service. After getting on the bus, the tour guide cut to the chase and told everyone to go shopping first. So we were taken to the first stop of today's one-day tour: China-Canada marine specialty store. Similar to yesterday's tea shop, there is also a small room dedicated to receiving tour groups. After tasting some seafood for everyone, a commentator began to give us a lesson. The product introduced by the commentator is called Shatai, which consists of shark liver oil and fish oil. It is a health product for regulating blood lipid and improving memory. In order to prove how this product can remove impurities from human blood vessels, the commentator took out a fish oil of other brands and made a comparative experiment with a fish oil of their company called Shatai. The commentator told everyone that the material of the convenient lunch box is similar to the molecular structure of impurities in human blood, so the fish oil that can dissolve the convenient lunch box is good fish oil. The narrator first drops other brands of fish oil into the convenient lunch box, and then pours boiling water into it. The convenient lunch box is only one layer thinner. Then he dripped shark fish oil into the lunch box and poured boiling water into it, so that the bottom of the lunch box would dissolve. The commentator told everyone that to buy fish oil, you must choose such a product. After class, the lecturer takes everyone to one of their machines to check the tourists' bodies for free. After the inspection of the company's instruments, most tourists have more or less problems with their blood vessels. Now that the problem has been found out, tourists can't help but spend money on this fish oil health care product. Convenient for the bottom of the lunch box to dissolve, indicating that fish oil can reduce blood fat? The reporter later consulted relevant experts. It turns out that the main component of the convenient lunch box is polystyrene, which has poor chemical stability, can be dissolved by various organic solvents, and will be corroded by strong acid and alkali. Some fish oils contain certain substances that can dissolve disposable lunch boxes. However, cholesterol and triglycerides in human blood are completely different from polystyrene in lunch boxes. It can dissolve polystyrene in lunch boxes, and cannot be confused with lowering cholesterol and triglycerides in the blood. This experiment is purely a concept of stealing and confusing people. And the doctor also said that the more you can melt the fish oil in the convenient lunch box, the worse it may be for the human body.
