To stay away from myopia, school-age children should supplement more of these nutrients
I no longer let my children play with mobile phones or watch TV, and I try to take my children to participate in outdoor activities as much as possible. Why do I still have myopia? In fact, malnutrition is also a common cause. What exactly is it? The Changchun Disease Control and Prevention WeChat public account released relevant tips.
Most children have a partial eclipse and do not like to eat fruits and vegetables. They especially like to eat sweet foods, such as candies, chocolates, and cakes. Frequent eating of sweet foods not only makes the eyes tired, but also causes myopia. To prevent children’s myopia, in addition to changing bad eye-use habits, parents must also pay attention to their children’s dietary nutrition. A balanced diet is also a beneficial factor in protecting eyesight.
One is to take in enough vitamins every day. Vitamin A is an important raw material that constitutes the photosensitive material of the eye. It has the function of protecting the eyes and other epithelial tissues and indirectly resisting infection. Carrots, cabbage, cauliflower, etc. are rich in vitamin A. Vitamin A in vegetables contains the antioxidant beta-carotene, an important substance for maintaining eye health. Kiwis, oranges, etc. are rich in vitamin C, which can remove free radicals that cause damage to the eyes; blueberries are rich in anthocyanins, which can promote pigment regeneration in the retinal cells of the eyes. Soy products such as soy milk and tofu contain fatty acids, calcium, vitamin E, vitamin B1 and other nutrients that are beneficial to the eyes.
The second is to ensure the intake of high-quality protein. Rhodopsin on the retina of the eyeball is composed of protein. When it is deficient, in addition to weak muscles, stunted development, and susceptibility to infection, edema, and anemia, the scleral tissue can be fragile and expanded, resulting in elongation of the axial length of the eye. You can eat more milk, meat and egg foods, which contain more protein. In addition, eggs contain lecithin, amino acids, progesterone and other nutrients that are beneficial to vision health. The lutein and zeaxanthin in egg yolk have strong antioxidant effects and can reduce the damage of ultraviolet rays to the eyes.
Third, calcium and phosphorus are indispensable. Calcium and phosphorus make the sclera tough and participate in the physiological activities of the optic nerve. When calcium and phosphorus are deficient, visual fatigue, distraction, and myopia are likely to occur. For example, milk, soy products, and dark vegetables are rich in calcium.
Fourth, trace elements and DHA cannot be ignored. Although the content of trace elements in the human body is less than one percent of body weight, they have a great effect. Without them, metabolism becomes difficult to carry out and children’s health will be affected. Trace elements such as zinc. Foods with higher zinc content include soybeans, milk, liver and other foods. Fish is rich in DHA, EPA, omega-3, vitamin A and other nutrients, which can promote eye development and help reduce eye fatigue. In addition, if you regularly eat hard foods such as nuts, fruits, corn, etc., the chewing process will strengthen the eye muscles and protect your vision. Too much sugar, especially added sugar, can affect children’s vision. To prevent myopia, it is best to consume no more than 25 grams of added sugar per day.
If you want to avoid myopia, the most important thing is to ensure adequate outdoor activities and develop good eye habits. In addition, do not be picky about food, eat less or no sweets, drink more milk, eat more fruits and vegetables, especially dark fruits and vegetables, and eat fish, poultry, meat, eggs and nuts appropriately.
