"One potato in 18 yuan, a hot pot restaurant, is 5 slices", which has been posted on a hot search recently, causing a heated discussion among netizens. According to the introduction of the Banu hot pot, the price is expensive because it uses selenium-enriched potatoes. What is the origin of selenium-enriched potatoes, and is it reasonable to be expensive? The reporter learned that Dr. Liu Jie confirmed that the potato is a product from his company Huasong Seed Industry, and its selenium content is hundreds of times that of ordinary potatoes. Food experts told reporters that selenium is an indispensable trace element in the human body. It is normal for selenium-enriched products to be more expensive than ordinary products, but if the price difference is too high, it is a gimmick.

In addition, a variety of foods contain selenium, so you can eat it in moderation, without deliberately supplementing it. Potatoes, also known as potatoes, are common cheap vegetables in daily life. According to its new regulation, selenium-enriched potato refers to the potato which is naturally enriched with selenium in the growth process or produced by selenium biological nutrition enhancement technology. The data show that selenium is one of the essential trace elements in human body and has certain antioxidant effect. A variety of foods contain selenium, so it is not necessary to deliberately supplement selenium-enriched potatoes. However, if there are many other nutrients, it is necessary to provide relevant data to confirm that it is not easy to draw conclusions at present. Selenium is unevenly distributed in different regions. Some places in China are seriously deficient in selenium, and the selenium content of agricultural products produced is low. Some places belong to selenium-enriched areas, and the selenium content in soil and water environment is high, so selenium-enriched potatoes are planted. In some areas, the selenium content in the environment is not high, but through selenium biological nutrition enhancement technology, such as spraying selenium-containing nutrient solution, potatoes can also be enriched with selenium.

talking about the impact on health, Fan Zhihong said that selenium is an indispensable trace element for human body, but many kinds of natural foods contain selenium, and animals contain more selenium than plants. People can supplement the selenium needed by human body by eating seafood and fish. If you live in a selenium-deficient area and have a low intake of animal food, you can buy selenium-enriched food to supplement it. But don't overdo it, and avoid eating a variety of selenium-enriched products at the same time. Excessive selenium will also do harm to health, just in moderation. Selenium is a trace element needed by human body, which is basically not lacking in normal diet. There is scientific evidence that proper intake of selenium may be beneficial to health.

Se-enriched potatoes and other Se-enriched foods will have a higher selenium content than the corresponding ordinary products. If the price difference is not big compared with the conventional products, they are still good products. If they are sold at a high price, it may be a gimmick.
