Where is the origin of selenium-enriched potatoes? Is it reasonable to be expensive? The reporter learned that Dr. Liu Jie confirmed that this kind of potato is the product of his company Song Hua Seed Industry, and its selenium content is several hundred times that of ordinary potatoes.
Food experts told reporters that selenium is an indispensable trace element in human body. It is normal that selenium-enriched products are 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, which can be eaten in moderation without deliberately supplementing it.
Potatoes, also known as potatoes, are common cheap vegetables in daily life. According to its new regulations, selenium-enriched potatoes refer to potatoes that are naturally rich in selenium or produced by selenium biological nutrition enhancement technology during growth. The data show that selenium is one of the essential trace elements for human body and has certain antioxidant effect.
A variety of foods contain selenium, so there is no need to deliberately supplement selenium-enriched potatoes. However, if there are many other nutrients, it is still necessary to provide relevant data to confirm, and it is not easy to draw a conclusion 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 potato can also be enriched with selenium through selenium biological nutrition enhancement technology, such as spraying selenium-containing nutrient solution.
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 they need by eating seafood and fish. If you live in a selenium-deficient area and the intake of animal food is low, 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 can also be harmful to the body, just in moderation. Selenium is a trace element needed by human body, and it is basically not lacking in normal diet. There is scientific evidence that proper intake of selenium may be beneficial to health. The selenium content of selenium-enriched foods such as selenium-enriched potatoes will be higher than that of corresponding ordinary products. If the price difference is not big compared with conventional products, it is still a good product. If it sells at a high price, it may be a gimmick.
