be careful! Patients with myopia should drink less carbonated drinks

Abstract: regular drinking of carbonated drinks can not only reduce physical fitness, but also deepen myopia. The occurrence and development of myopia is the result of the joint action of genetic factors, environmental factors and nutritional factors. When we use our eyes closely, such as reading and writing, our eyes will have a collective effect.

some nutrients can slow down the progress of myopia, such as zinc, chromium, calcium and so on; Some nutrients may promote myopia, such as sugar, carbonic acid and so on. Everyone likes carbonated drinks, but drinking too much will do harm to the body, especially the eyes. There are many reasons for the formation of

and

myopia. There are genetic factors, environmental factors and nutritional factors. Genetic factors needless to say, we often see a family wearing glasses. Environmental factors refer to the formation of myopia, which is mainly related to seeing too close and too little outdoor activities. Some nutrients can slow down the progress of myopia, such as zinc, chromium, calcium, etc; Some nutrients may promote myopia, such as sugar, carbonic acid and so on. Everyone likes carbonated drinks, but drinking too much will do harm to the body, especially the eyes.

eyes need to develop day after tomorrow. When

were born, our eyes were still semi-finished products, belonging to “congenital hypoplasia”; To continuously improve in growth, we need “acquired development”. In view of this situation. The normal visual acuity of 1-year-old children is 0.2, 0.4 at 2 years old, 0.6 at 3 years old, 0.8 at 4 years old and 0.9 at 5 years old. It can reach 1.0 at 6 years old.

and

teenagers before the age of 12 have short ocular axis, which is physiological hyperopia. The hyperopia of 4-year-old children is 220 degrees, 210 degrees at 5 years old, 200 degrees at 6 years old, 150 degrees at 8 years old, 100 degrees at 10 years old and 50 degrees at 12 years old. During the development of the eyeball, the eyes gradually change from hyperopia to emmetropia, and the length of the eyeball gradually increases. At the same time, the visual system is constantly improving with the growth of the body. If the anterior posterior diameter of the eyeball increases too fast in the process of emmetropia, myopia will be formed. How does

and

carbonated drinks aggravate myopia?

and

often drink carbonated drinks, which can not only cause the decline of physical quality, but also deepen the degree of myopia. The occurrence and development of myopia is the result of the joint action of genetic factors, environmental factors and nutritional factors. When we use our eyes closely, such as reading and writing, our eyes will have a collective effect. At this time, the internal rectus muscle of the eye contracts, the eyes turn inward, and the muscle pressure on the eyeball increases. Continuous pressure on the eyeball can lead to elevated intraocular pressure. If the calcium in the body is reduced due to frequent drinking of carbonated drinks, the content of calcium in the sclera is reduced, and the eyeball wall loses normal elasticity, the eyeball is easy to be elongated, resulting in a rapid increase in the degree of myopia. When myopia occurs in

and

, most people will wear concave lenses for correction. The degree of the peripheral area of most myopia lenses is higher than that of the central area, resulting in the central optical focus of teenagers wearing glasses falling on the retina and the paracentral optical focus falling behind the retina, forming the paracentral myopic defocus. The retina in the surrounding area tries to get close to the focus, causing the eyeball to grow longer. If you often drink carbonated drinks, it will reduce the content of calcium in the eyeball, weaken the toughness of the eyeball wall, and can not effectively resist the trend of eyeball lengthening caused by myopic defocus, which will aggravate myopia.

and

are nutritionally balanced to prevent myopia. Can’t

and

be carbonated drinks? You can drink, but don’t drink too much. Some teenagers drink carbonated drinks as water and eat them as rice, which is not desirable. Drink more boiled water and don’t be picky about eating. Only in this way can we ensure balanced nutrition and be conducive to the development of the body, especially the eyes. The study found that most myopic people still lack trace elements such as zinc and chromium. In addition, eating more sugar will reduce the content of growth factor “protein 3” in the body, which is an effective substance to inhibit eye growth.

someone will ask if I can drink more carbonated drinks after eating calcium tablets. It’s like eating a meal and taking cathartic drugs. Most of the nutrients in the meal can’t be absorbed. Similarly, after eating calcium tablets and drinking carbonated drinks, most of the calcium can not be absorbed. In addition, drinking a lot of carbonated drinks will take away the calcium stored in the body.

teenagers should eat more foods with high calcium content such as animal crispy bones, beans, shrimp skin, eggs, peanuts and jujubes, and drink less carbonated drinks, especially cola drinks. Only in this way can we ensure the daily calcium intake, strengthen the body and slow down the deepening of myopia.

there are three harmful effects of drinking carbonated drinks.

one is affecting the digestive system. No matter what flavor of carbonated drinks, the ingredients that make you feel very cool and exciting are carbon dioxide. Sufficient carbon dioxide has bacteriostatic and bactericidal effects, but drinking too much carbonated drinks is harmful to gastrointestinal digestion, because a large amount of carbon dioxide not only inhibits bacteria in drinks, but also inhibits beneficial bacteria in the body. The cold water and a large amount of carbon dioxide will also cause abdominal distension, affect appetite, and even cause gastrointestinal dysfunction.

and

lead to obesity and damage to teeth. Too much sugar in drinks is absorbed by the human body, which increases calories. Long term drinking will cause obesity. More importantly, this kind of drink is very popular with teenagers and is easy to be addicted. In this way, the sugar and acid in the drink are very unfavorable to the child’s tooth development and easy to rot the tooth.

and

lead to early-onset osteoporosis. Most cola drinks also contain phosphoric acid. Calcium and phosphorus are a balanced partner. Excessive intake of phosphorus will hinder the absorption of calcium. Therefore, regular drinking of cola drinks will reduce the storage of calcium in bones. The probability of early age of osteoporosis in adulthood is three times that of others.
