Plano Eyeing Science | Your eyes desperately need this food! 80% of people don't eat enough

To be honest, children are holding their mobile phones and iPads for a long time now, and the frequent use of their eyes will cause them to unconsciously one day, parents suddenly find that the baby is squinting and watching TV! Children's vision problems have become more and more serious in recent years, and they are getting younger and younger. Parents who go to the school gate to pick up their children from school will feel it. Almost all of them are young but wear glasses. In real life, although many parents are worried about their children's vision problems, there are some misunderstandings in their concepts. For example, only when their children say that their eyes are uncomfortable, and there are obvious symptoms of squinting, they think of taking their children to the hospital for visual inspection and glasses. This kind of problem is definitely not a good way to solve it. We need to make preventive preparations in advance in peacetime! The vision of children with lutein deficiency is a gradual development process, and TV, computers, mobile phones, tablets, etc. in life will produce blue light that damages children's delicate vision, directly causing damage to the retina, causing many eye diseases. But these electronic products cannot be avoided in life. How to solve the prevention? At the same time, many parents will wonder why their children do not play with electronic devices for a long time, and their daily routine is very regular, but their eyesight is decreasing year by year? The answer is to add more lutein! If the nutrients obtained by the eyes are insufficient to support their normal work, it is easy to cause various eye problems, such as eye fatigue, sensitivity, decreased vision, etc., and even blindness. In other words, if you don't eat enough vegetables, your body doesn't get enough lutein, causing your eyes to fall into "malnutrition". Protecting the retina, enhancing vision Epidemiological studies have shown that higher concentrations of lutein and zeaxanthin in eye tissue are associated with significantly lower risks of AMD (57 to 82 percent) and cataracts (32 to 42 percent) [1-4] . The results of domestic clinical studies show that: Lutein intervention can improve the visual function of patients with early age-related macular degeneration [5]. Supplementation with lutein and zeaxanthin also resulted in increased visual acuity and reduced foveal thickness in patients with diabetic retinopathy [6]. Lutein is the most important nutritional component of the human retina. It contains high concentrations of lutein in the macula (center of vision) and lens of the retina of the eye. Unfortunately, lutein cannot be synthesized by the human body. If you want to supplement lutein, it must be absorbed from food, and then break through all difficulties, enter the lens and retinal macula, play an antioxidant effect and neutralize harmful free radicals, absorb blue light that is harmful to the eyes, and prevent the light from causing oxidation to the eyes. damage, like natural sunglasses that filter blue light. In addition, it can relieve symptoms such as dry eyes, blurry eyes, and photophobia. In addition, high myopia can easily lead to retinal detachment, hydrops and other fundus diseases, and even lead to permanent blindness. Supplementing enough lutein can improve eye resistance and reduce the incidence of lesions. How to Supplement Lutein Lutein is a carotenoid that is yellowish-orange and mainly found in yellow or orange-yellow vegetables and fruits. And because carotenoids and chlorophyll are associated pigments, the brighter and darker the green color, the higher the lutein content. Generally speaking, the content of green leafy vegetables is very high. Lutein is also found in small amounts in many animal foods, such as eggs and milk. Although the content of lutein in animal foods is low, its absorption and utilization rate is relatively high. For example, although the content of lutein from egg yolk is lower than that of many vegetables, its absorption and utilization rate is three times that of plant foods with the same content. times, so don't overlook their important role. Lutein was added as a dietary supplement as early as 1996, and the recommended daily dose is about 6 mg. According to the recommendation of the Chinese Nutrition Society, the recommended daily intake of lutein for Chinese adults is 10mg, which is 10,000μg. We also list the content of lutein in some common Chinese foods in the table below. You can plan your own accordingly. meal. When we are born, our body has already stored a certain amount of lutein. Every day we grow up, lutein is consumed, so it needs to be continuously replenished through diet. Common foods that are rich in lutein are: carrots, leeks, amaranth, pumpkin, celery, parsley, spinach, cabbage, spinach, lettuce, lettuce, broccoli, green peppers, corn, eggs, etc. If there are picky eaters, parents must pay attention to their balanced diet and cultivate their good habit of eating vegetables from an early age, which is also to protect their eyesight!
