Parents may be more likely to be myopic when they give their children these things!
For many people, the temptation of sweets is hard to resist, especially for children. Colorful sweets, delicious cakes, refreshing ice cream, soda drinks of all tastes... Children can't pull their legs at first sight, but parents should pay attention to the fact that children who eat too much sweets are not only prone to gain weight, tooth decay, but also easy to be short-sighted, so parents must control their children's intake of sweets.
1. Eating too much sweets may cause myopia to accelerate
The eyeballs of adolescents are in the developmental stage, the eye wall is very stretchable, and the sclera texture is hard and elastic.
However, when calcium is deficient, the strength of the sclera will be relatively reduced, and under the long-term mechanical pressure of the extraocular muscles, the eyeball wall is easy to gradually extend, from spherical to oval, and the distance between the cornea and the lens to the retina is elongated, so that the image cannot be imaged on the retina, resulting in myopia.
Sweets are a favorite food for many children, but sugar needs a lot of vitamin B1 when metabolized in the body, and if the sugar intake is too much, vitamin B1 is insufficient. Vitamin B1 deficiency can affect the growth and development of the optic nerve, which can lead to a loss of vision. Excessive intake of sugar will also reduce the calcium in the body, weakening the elasticity of the eyeball and contributing to the development of myopia.
2, carrots, pork liver moderate intake is good
In our country, there has always been a tradition of dietary therapy, and various eye-protecting foods such as carrots and pork liver are also popular.
Indeed, eating carrots is indeed beneficial to the eyes, because carrots are rich in β-carotene, which can be converted into vitamin A in the human body - retinol, which is the key to synthesizing the photoreceptor UV in visual cells, and adequate intake has a certain effect on preventing night blindness, but it is of little help for myopia. In addition to carrots, pumpkins, sweet potatoes and dark green leafy vegetables (hollow cabbage, spinach, broccoli, etc.) are all good sources of β-carotene.
The liver is an important organ for storing vitamin A in animals, and 100 grams of pig liver contains about 5000 micrograms of vitamin A, which has a certain effect on maintaining healthy vision, but it also cannot prevent the occurrence of myopia. Eating more is not necessarily good for the body.
3, protect the eyes, the key is still in the habit
Instead of counting on a specific food to protect your eyes, it makes more sense to focus on a balanced diet for your child. In addition to diet, parents should also pay attention to supervising their children and develop good eye habits.
Keep your eyes at a distance from electronic screens and books. When looking at the tablet, the distance should not be less than 40 cm, if watching TV, you should keep the distance diagonal of the TV screen more than 6-8 times. If you read a book, your eyes are a foot away from the book.
Participate in more outdoor activities. Studies have shown that sunlight can stimulate children's vision development, and on sunny days, children can participate in more outdoor activities. During the epidemic, children can be allowed to "see" the sun on the balcony.
