Staying up late to study, working overtime, modern people use electronic products for a long time, and their eyes are easy to get tired and dry, so many people will choose to supplement some nutrients - lutein. In the "Anti-Sudden Death Package" that was popular on the Internet not long ago, lutein, known as the "Golden Eye", was "on the list". Searching on the e-commerce platform, it was found that there are many brands of lutein-related health products on the market, and lutein gummies for children have become the first on the Double 11 best-selling list. Nowadays, lutein is "popular" at all ages, what does this do to the eyes? Can myopia be prevented?
Hot list
Jin Hui, chief physician of the Department of Clinical Nutrition of Zhongda Hospital Affiliated to Southeast University, said that lutein is a carotenoid and the main pigment present in the macular area of the retina under the human eye, which has the effect of antioxidant and blue light absorption. "The human body cannot synthesize lutein on its own, and needs to be ingested through daily diet, such as spinach, kale, etc. Lutein supplementation, to a certain extent, can protect the eyes from blue light damage, and has a limited effect on relieving eye fatigue, but there is no scientific basis for preventing myopia. ”
Netizen "Ah La" was also a loyal fan of lutein before, but recently "overturned". She said, "I have to stare at the screen for more than ten hours a day, my eyes are so tired that I can't open them, and I wake up with red blood, and I am not so tired when I look at my phone after supplementing lutein." I thought that the more I ate, the better the effect, but the person turned yellow. She used the experience of people who came before her to warn everyone, "Lutein must not be eaten indiscriminately." ”
Netizens shared
Jin Hui introduced that lutein, as a carotenoid, will cause the skin to appear yellow if intake too much, and the side effects of skin discoloration are generally not a big problem, and you can slowly recover by stopping taking lutein.
"The recommended daily intake of lutein is 10 mg, with a maximum intake of no more than 40 mg. In addition, it is not recommended to take lutein for a long time, because excessive lutein supplementation may damage liver and kidney function, and it is best to take it under professional guidance. She reminded.
By comparing different brands of lutein health products, it was found that some products contain lutein in the ingredient list, and some are lutein esters. What is the difference between these two ingredients?

"What the human body can absorb is lutein, and lutein esters also need to be broken down into lutein in the body before they can be absorbed. However, lutein molecules are highly unsaturated and unstable to light, heat and ultraviolet rays, while lutein esters are more stable in comparison. Jin Hui said that for the people, it is better to consume more from food than to supplement lutein through health products, "Lutein is widely found in dark green leafy vegetables, as long as people's diet is balanced, there is no problem of insufficient intake." In particular, many mothers like to supplement lutein gummies to their children, and it is not recommended to blindly follow the trend, one is to pay attention to the intake of lutein, and also to care about whether the sugar exceeds the standard. ”
