When it comes to children’s myopia, parents mostly blame it on watching TV, playing video games, too dark or too strong light, incorrect posture in reading and writing, etc. However, many studies have shown that children’s partial diet and improper arrangement of food are also factors that can cause myopia. The following is an analysis of these factors: Factor 1: Partial eating Harmful analysis: Children and adolescents are the most rapidly developing stage of the human body, and their bodies have a strong demand for various nutrients, while partial eating can lead to an unbalanced intake of nutrients, which not only affects the growth and development of the body, but also affects the development of the eye. Lack of protein, vitamins, trace elements (calcium, phosphorus, zinc, chromium) can cause myopia or make myopia develop further. Suggestions: Children and adolescents must have a varied and comprehensive diet, and must not be partial. Factor 2: Eat more sweets Harmful analysis: Most teenagers like sweets, eating too much sugar may make the body’s blood acidic. The body needs to maintain the acid-base balance, and has to mobilize a lot of calcium to neutralize the acid, thus causing a shortage of blood calcium, weakening the elasticity of the eye wall, so that the eye axis elongation and promote the production and development of myopia. If too much sugar is consumed, vitamin B will be consumed excessively, thus affecting the normal supply of vitamin B required by the optic nerve. It is advisable to minimize the intake of sweet foods such as chocolate, milk sugar and other foods. Since paranoia and excessive consumption of sweet foods are harmful to myopia, what substances have a preventive effect on myopia? Recommendation 1: Protein Myopia prevention and control role analysis: protein is the most basic substance to maintain the body’s life activities, by 20 kinds of amino acids through different combinations of protein with different functions, in terms of the sclera tissue it can become the tough shell of the eye, is a variety of proteins including leucine, isoleucine, lysine and other essential amino acids, constituting a tough collagen tissue, myopia is mainly Myopia is mainly axial myopia, which means that the eye axis becomes longer and the external image falls in front of the retina, causing blurred vision. Many amino acids can be synthesized in the body itself, but some amino acids such as isoleucine, lysine and other essential amino acids cannot be synthesized by our body and need to be consumed in food. Meat, eggs, milk and other animal proteins contain essential amino acid types and ratios similar to the human body needs, its nutritional value is high, for children and adolescents are in the growth and development period for the nutrient demand is strong, so should ensure the intake of meat, eggs and milk in the diet. Recommended two: vitamins and trace elements myopia prevention role analysis: vitamin is to maintain normal growth and development and metabolism of a class of substances necessary to regulate the physiological functions of the body has an important role. For example, vitamin A is the key substance that constitutes retinal red matter. In addition, it can also promote growth and development and maintain the integrity of epithelial cells, if the lack of it will suffer from night blindness, dry eyes and dry skin; vitamin D can regulate the metabolism of calcium and phosphorus and promote the absorption of calcium and phosphorus, if the lack of it children will suffer from rickets. In addition, some experts believe that the lack of calcium is one of the important causes of poor vision development and even the formation of myopia. And vitamin E has the role of preventing biological oxidation and protecting biofilm, it can prevent the oxidation of vitamin A, improve the metabolism of the ciliary muscle, it is reported that the hair vitamin E has a role in the treatment of myopia. And the B vitamins play an important role for the metabolism of various nutrients. Vitamins and trace elements cannot be synthesized in the body and must rely on the supply of food. Animal liver, dairy and fish are rich in vitamin A and vitamin D; fresh vegetables and fruits are rich in vitamin C; rice, malt and other foods contain a large number of vitamin B components, so a comprehensive and reasonable diet can ensure that the body gets a full range of vitamins and trace elements. Recommended three: Chinese medicine food therapy myopia prevention and treatment role analysis: Chinese medicine believes that the cause of myopia is mainly spleen weakness, liver and kidney deficiency, loss of qi and blood, so the prevention and treatment of myopia can be appropriate tonic. Meat, eggs, animal liver and kidney, crucian carp, yellow fish, sea cucumber, shrimp, snapper, cinnamon, lychee, grapes and walnuts have the effect of nourishing the spleen and benefiting the kidney. Chinese medicines such as ginseng, ginseng, astragalus, yam, wolfberry, cassia, mulberry and jujube also have the effect of nourishing the spleen and benefiting the kidneys, which can be consumed in the daily diet. Scientific and nutritious meals and correct eating habits will not only provide you with comprehensive nutrition but also give you a pair of bright eyes, you may want to try it.
