Did the child’s myopia come from eating?

Abstract: no matter how old you are, you may have the impression that compared with more and more “small glasses”, you had much less myopia ten or even decades ago., No matter how old you are, you may have the impression that compared with more and more “small glasses” now, you had much less myopia ten or even decades ago.,

no matter how old you are, you may have the impression that compared with more and more “small glasses”, you had much less myopia ten years ago or even decades ago.

you may wonder: why is the gap between two adjacent generations so large? Experts point out that this may be “traced” to the mother’s diet when she was pregnant. The modern diet structure determines that pregnant women eat too many drinks and fine grains, resulting in too high sugar in the body and premature development of fetal crystals, which is more likely to lead to myopia. Excessive sugar leads to excessive fetal crystal development. Nowadays, due to the continuous improvement of living standards, people’s diet structure is becoming more and more refined, and they eat more and more fine grains, including more and more sugar. As we all know, excessive intake of sugar in the body is harmful to the development of eyes. From the analysis of nutritional composition, for a normal person, excessive intake of sugar may cause the accumulation of sugar in the body. When sugar is metabolized in the body, a large number of vitamins are required, so vitamins will be insufficient due to excessive consumption. The development of ocular visual cells also needs a lot of vitamins. This is especially true for pregnant women. If you eat too much sugar, it will lead to abnormal crystal development environment, rapid ocular axis development and accelerate the occurrence of myopia. Animal experiments have shown that allowing experimental animals to eat too much sugar has an impact on their eyesight. Infants and young children have physiological hyperopia. Children are born with certain hyperopia, which is a normal process of eye development, called physiological hyperopia. Because the eyeball of infants is smaller than that of adults, the eyeball size of infants at 6 months is only equivalent to 2 / 3 of that of adults, and the distance between the eye axis is shorter than that of fully developed normal eyes, so the image will be formed behind the retina to form physiological hyperopia. From the child’s birth to the age of 7, the child’s eyeball develops most rapidly, the eye diopter also gradually moves towards myopia, and the degree of hyperopia gradually decreases. If it exceeds the normal range, it is abnormal or pathological hyperopia. With the growth of children’s age, the focus moves forward, and the hyperopia gradually transitions to emmetropia. Sugar can “eat” the time of fetal hyperopia, and the influence of sweet food on myopia can not be ignored. The development of children from hyperopia to myopia can be divided into the following steps: physiological hyperopia, emmetropia and myopia. The normal value is about 200 degrees of hyperopia at the age of 3 ~ 4, 150 degrees of hyperopia at the age of 4 ~ 5 and 100 degrees of hyperopia at the age of 6 ~ 8. However, the excessive myopia of children may be related to the excessive intake of sugar during pregnancy, resulting in premature crystal development of children. Children’s eyesight is close to adulthood too early, which may make them directly “skip” physiological hyperopia. They are born with emmetropia, which shortens the time to develop into myopia, and the number of children with myopia begins to increase. The sugar content in fine grains and drinks is high, so it is no coincidence that parents have less myopia, Zhang Hong analyzed. Maybe people aged 40 ~ 50 have such a memory, lying in the quilt and reading comic books with a flashlight, but people in that era were less myopic. But now, under the protection of eye protection lamps and anti radiation screens, the number of children with myopia has only increased a lot. This may be related to the diet. With the improvement of living standards, our diet is becoming more and more refined. Coarse grains are gradually replaced by fine grains, and some high sugar diets are unconsciously entering our table. Like drinks, refined rice, refined noodles, etc. Although the taste is good, taking refined rice as an example, in the process of processing, layer by layer shelling will also lead to the loss of vitamins. When processed into refined rice, there are few vitamins left that are beneficial to eye development. Pregnant women should pay attention to the combination of thickness and detail in their diet. A scientific and systematic pregnancy recipe should pay attention to the combination of thickness and detail and a comprehensive diet. Staple food, non-staple food and fruit should master the quantity and variety. Staple food should transition from whole grain (such as rice, white flour, etc.) to coarse and fine combination, and eat more whole wheat, beans, sorghum rice, corn and other coarse grains; For example, drinking water should also avoid excessive intake of drinks. Too much sugar has a bad impact on the visual development of the fetus. Drink as much boiled water as possible to replenish water. What foods are good for fetal eye health? Fruits and vegetables are good choices. Although fruits are rich in vitamins that are good for the eyes, it doesn’t mean you can eat as much as you like. Pregnant women should also control their fruit intake, otherwise it is easy to affect their children’s development and cause macrosomia. Therefore, the daily fruit intake of pregnant women should not exceed 1 kg. Green vegetables also contain a lot of vitamins, such as carrots and tomatoes. In addition, you should eat more nuts, such as walnuts, chestnuts, pine nuts, etc. in addition to linoleic acid and linolenic acid, which can promote the retina, the vitamins, calcium, zinc and other minerals also have a direct impact on the normal development of vision and can help the development of visual cells; Fish and animal liver are also good choices, which are rich in nutrients such as protein, vitamins, trace elements and cholesterol, which are beneficial to promote children’s growth and development and maintain health.
