According to reports in the British media, a 16-year-old boy from Australia had partial eclipse because of his childhood. His three meals a day ate mainly fried chicken fries, which led to nutritional imbalances. From the age of 14, he had severely deteriorated his eyesight, even to the point of almost blindness. The parents took him to visit the doctor, and finally the doctor found that his vision problems were caused by vitamin A deficiency caused by partial eclipse. Under the doctor's treatment, his right eye vision recovered, but his left eye had caused permanent damage and he was no longer cured. Now my children are getting more and more of myopia and getting younger and younger. According to the latest survey conducted by the State Ministry of Education and the Health and Development Commission, at present, there are more than 400 million myopia patients in China, the incidence rate of myopia is 33.3%, the myopia rate of primary school students exceeds 25%, the myopia rate of junior high school students reaches 70%, and the high school students’ myopia rate reaches 85. %, it grows at an annual rate of 8%, ranking first in the world, among which young people are the “hard-hit areas†for myopia. In addition to genetic factors, myopia in most children is caused by the day after tomorrow. In addition to paying attention to reducing children’s time to play with electronic products and paying attention to eye habits and eye health, dietary nutrition also has an important impact on children’s vision. It is not just vitamin A deficiency that can cause damage to the eyes or vision. Vitamin C, vitamin E, and lutein have important health benefits to the eye. Vitamin A, the guardian of the child's eyesight Vitamin A is an integral part of the photoretin pigments in the retina. It is an essential nutrient for protecting the eyes and maintaining vision. Vitamin A, also known as retinol, is the key to the synthesis of photosensitive materials in visual cells and has a close relationship with the visual function of humans and animals. If vitamin A deficiency results in failure of photoreceptor synthesis in visual cells, it is prone to night blindness and loss of vision (which can lead to total blindness). Vitamin A helps the eye make tears, so that the eyes can maintain moisture. In the absence of vitamin A, the production of tears can be affected. If the eyes are not moistened for a long time, dry eyes may appear, leading to dry eyes and even conjunctivitis. When it is allowed to develop, the cornea can be damaged, and infections and ulceration can occur. In severe cases, blindness can also result. However, the more vitamin A, the better. If you take vitamin A over long-term, it will cause severe poisoning and even death. Repeated use of vitamin A within a few weeks to several years, taking more than ten times the recommended intake will cause chronic vitamin A toxicity. "Chinese people's dietary reference intake 2013 edition" recommended that children's daily intake of vitamin A is 310-670 ugRE/d (microgram retinol equivalent/day), tolerable maximum intake is 700-2100 ugRE/d, children above this intake are prone to vitamin A poisoning. Therefore, in general, as long as the nutrition is balanced, the child is not picky eaters and does not need additional vitamin A supplements. Food Source: food Vitamin A content (100 g edible portion) Pig liver 4972ugRE Beef liver 20220 ugRE Duck liver 4675 ugRE Chicken liver 10414 ugRE carrot 688 ugRE Winter leeks 1158 ugRE pumpkin 148 ugRE cantaloupe From 153 ugRE we can see from the food source that the liver vitamin A content is very rich, so when parents want to give their children an animal liver, they must pay attention to the amount. Vitamin C, let the child's eyes work properly The important role of vitamin C in the eye, from two aspects. Retina Scientists at the University of Oregon Health and Science found that the retina needs to be “bathed†in a higher dose of vitamin C to function normally. When the vitamin C in the environment of the retina is removed, the retina does not work properly. . In addition, because the retina has an active metabolism, a high oxygen consumption, a high content of unsaturated fatty acids, and is often exposed to visible light, it is vulnerable to oxidative damage, which may be the cause of a variety of retinal choroidal lesions. Studies have shown that high levels of antioxidant vitamin C can significantly reduce the risk of associated vision loss. 2. The lens The crystal is an important part of the refractive system of the eyeball, and is the only refractive interstitial with the ability to adjust. Cataracts can occur if the crystal is partially or totally cloudy due to various reasons. Cataracts do not only occur in elderly people. Statistics show that about 30% to 40% of blind children in China are caused by cataracts. Studies have confirmed that lens epithelial cell apoptosis is the underlying cause of all types of cataract formation except congenital cataracts, and oxidative damage is one of the important causes of apoptosis. The antioxidant effect of vitamin C can prevent the oxidative damage of lens epithelial cells, inhibit the apoptosis of lens epithelial cells and delay or inhibit the occurrence of cataract. Thus, we can know that if there is a lack of vitamin C, the retina will not work properly and it will also accelerate the apoptosis of the lens epithelial cells and cause cataracts. Therefore, it is necessary to add more vitamin C-rich foods to your child's diet. The "Chinese Dietary Reference Intake 2013 Edition" recommended that children daily intake of vitamin C 40-90mg/d (mg/day), tolerable maximum intake of 400-1400mg/d. Food Source: food Vitamin C content (100 g edible portion) Hawthorn 53mg date 243mg Kiwi 62mg papaya 43mg Tangerine 35mg Radish 45mg Chinese cabbage 47mg broccoli 51mg In addition, the general green vegetables are also rich in vitamin C, such as spinach, kale and so on. Vitamin E makes your child's eyes live longer Vitamin E is also an antioxidant that acts primarily on the lens of the eye. Vitamin E and vitamin C work together to prevent the oxidation and degeneration of the lens, maintain the transparency and elasticity of the lens, delay the aging of the eyes, and prevent the occurrence and development of myopia. Food sources: Vitamin E is rich in vegetable oils. Sesame, walnuts, and other nuts and their products are also the best foods for taking vitamin E. Lutein, let the child's eyes shine Lutein is the only carotenoid found in the retina of the eye and in the lens. Foreign studies have shown that lutein is the main component of the eye's retina and macula that cannot be lost and can prevent eye damage. Because lutein is a potent antioxidant, it can absorb ultraviolet and blue light, avoid ultraviolet and blue light damage to the eyes, and resolve eye light poisoning. Computers, mobile phones, and iPads all emit a lot of blue light. If children stare at them for a long time, it is very easy to cause photoreceptor cell apoptosis and damage to photoreceptor cells in the macula. Children's schoolwork pressure, easy to use eye fatigue, and lutein has vasodilator function, improve blood circulation microcirculation, promote the supply of nutrients, children with eye fatigue have a good mitigation. Loss of lutein can cause vision loss and blindness. Studies have shown that high intake of lutein helps delay the aging, degeneration, and disease of the eyes, reduce the incidence of eye diseases, and protect the retina from light. Food sources: kiwi, corn, egg yolk, dark green and yellow-orange vegetables such as spinach, cauliflower, onion, red leeks, asparagus, rape, etc. In general, children usually have a balanced diet and do not need to supplement these nutrients. However, if a child has problems with picky eaters and partial eclipses, parents must pay attention!
