What does sugar have to do with myopia?

Abstract: eating too much sugar will also increase the degree of myopia! Because of too much sugar, the blood sugar increases, which correspondingly reduces the osmotic pressure of body fluid, so that the aqueous humor in the eyeball penetrates into the crystalline body, causing lens deformation, increased diopter and aggravating myopia.

“uncle, I’m here again!” The 5-year-old girl shouted to the doctor as soon as she entered the door. Mingming’s mother said that when Mingming was 3 years old, she narrowed her eyes and went to the hospital for examination. She found that she was short-sighted. She has been wearing glasses since then. The degree has risen again in the past two years. Now it’s 300 degrees. “I’m not short-sighted, and her father is not short-sighted. I don’t know why the child is short-sighted?” Mingming’s mother, “I’m nearsighted before I go to school. There’s still a long way to go in the future. How can I go?

the main cause of children’s nearsightedness is unscientific eye use. They spend too much time watching TV and using the computer, mostly more than two or three hours a day. Another important reason is too much sugar!

When sugar is metabolized in the human body, it needs a lot of vitamin B1 to help and reduce the content of calcium in the body. Vitamin B1 has a protective effect on the optic nerve, and its content will affect the state of the optic nerve. Calcium is the “protector” of eye tissue. Calcium deficiency will not only reduce the elasticity of retina, increase the pressure in crystalline body, elongate the anterior and posterior diameter of eyeball, affect the tenacity of eyeball wall and be prone to myopia.

too much sugar will also increase the degree of myopia! Because of too much sugar, the blood sugar increases, which correspondingly reduces the osmotic pressure of body fluid, so that the aqueous humor in the eyeball penetrates into the crystalline body, causing lens deformation, increased diopter and aggravating myopia.

the harm of eating too much sugar

1 endocrine system disease

candy or sweets contain a lot of sugar and high calories. Eating too much is easy to lead to obesity. After getting fat, it may also cause cardiovascular diseases.

excessive sweets will also increase the burden on the pancreas. The body in a high glucose environment for a long time, which will upset the body’s original balance of the internal environment, blood sugar secretion too much, the risk of diabetes. Especially children with family history of diabetes should pay more attention to eating less sugar and taking more exercise.

2 myopia

what is the relationship between eating sugar and myopia? It really matters! When

sugars are metabolized in the human body, they need a lot of vitamin B1 to help and reduce the content of calcium in the body. Vitamin B1 has a protective effect on the optic nerve, and its content will affect the state of the optic nerve. Calcium is the “protector” of eye tissue. Calcium deficiency will not only reduce the elasticity of retina, increase the pressure in crystalline body, elongate the anterior and posterior diameter of eyeball, affect the tenacity of eyeball wall and be prone to myopia.

too much sugar will also increase the degree of myopia! Because of too much sugar, the blood sugar increases, which correspondingly reduces the osmotic pressure of body fluid, so that the aqueous humor in the eyeball penetrates into the crystalline body, causing lens deformation, increased diopter and aggravating myopia.

3 malnutrition

candy and sweets are not very high in calories? How can you be malnourished? In fact, high calories and nutrition are not the same thing! Because sugar can only supply calories and has no other nutritional value. When eating more sugar every day, eating other nutrients is bound to reduce, resulting in the lack of protein, vitamins and minerals in the body, which is very easy to cause nutritional imbalance.

some children don’t want to eat when they eat too much sugar. If they accidentally suffer from dental caries and pain when chewing food, it will also affect their appetite. As time goes on, it will lead to nutritional deficiency and affect their growth and development.

4 withdrawn

some children are not only eccentric, but also active, inattentive and poor academic performance. A survey found that a considerable part of children with similar symptoms are related to excessive intake of sweets.

and

from the perspective of medicine, if there is too much sugar in the body, the metabolites such as pyruvate and lactic acid will increase significantly. At this time, a large amount of vitamin B1 needs to be consumed to accelerate the excretion of these metabolites. However, vitamin B1 cannot be synthesized naturally in the body and depends entirely on food intake, But partial eclipse children are difficult to eat more foods containing vitamin B1. When vitamin B1 is deficient in the body, sugar metabolites such as pyruvate will accumulate in the brain and cause children’s personality abnormalities.

5 reduce immunity and affect sleep

a recent study found that sweets can reduce human immunity. Under normal circumstances, the average phagocytic capacity of a white blood cell in human blood is 14. After eating a dessert, it will become 10, after eating a sugary dessert, it will become 5, and after eating a piece of cream chocolate, it will become 2. It can be seen that sweets have a certain impact on immunity.

in addition, eating too many sweets also has adverse effects on sleep. Researchers have investigated 1000 people with sleep disorders and found that more than 87% of them like sweets.
