Eight essential nutrients for children’s eye development

Abstract: the increase of blood glucose will accelerate the degeneration of lens, cause the change of osmotic pressure of lens and aqueous humor, increase the diopter, and lead to myopia; High blood sugar can cause diabetes, cause retinopathy and affect eyesight. Many literary works say “clear and bright big eyes” when describing someone’s good-looking eyes. It can be seen that children’s eyes are the purest period in their life. At the same time, this stage is also the most critical period for vision development. Therefore, it is necessary to ensure that the nutrients required for baby’s eye development are sufficient., Eye development requires 8 nutrients, vitamin A, to maintain the normal growth and differentiation of all cells in the body and participate in the synthesis of rhodopsin. Rhodopsin decomposes when the light is dark, so as to stimulate nerves to form vision, so that we can see objects when the light is dark. If you lack vitamin A, you will reduce your dark adaptation ability, which can lead to blindness., Food source: animal sources include liver, eggs and milk; Plant sources include broccoli, carrots, spinach, pumpkin, mango, etc., DHA, the most abundant polyunsaturated fatty acid in retinal photoreceptors, can be produced by α- Transformed from linolenic acid, it is necessary to maintain the normal function of rhodopsin and is very important for the development of baby’s vision., Food sources: fish (preferably deep-sea fish), linseed oil, algae.

many literary works say “clear and bright big eyes” when describing someone’s good-looking eyes. It can be seen that children’s eyes are the purest period in their life, and this stage is also the most critical period of visual development. Therefore, it is necessary to ensure sufficient nutrients for baby’s eye development.

eye development requires eight nutrient elements

vitamin a

to maintain the normal growth and differentiation of all cells in the body and participate in the synthesis of rhodopsin. Rhodopsin decomposes when the light is dark, so as to stimulate nerves to form vision, so that we can see objects when the light is dark. If the lack of vitamin A will reduce the dark adaptation ability, which can lead to blindness.

and

food sources: animal sources include liver, eggs and milk; Plant sources include broccoli, carrots, spinach, pumpkin, mango, etc.

DHA

is the most abundant polyunsaturated fatty acid in retinal photoreceptors, which can be determined by α- Transformed from linolenic acid, it is necessary to maintain the normal function of rhodopsin and is very important to the development of baby’s vision.

and

food sources: fish (preferably deep-sea fish), flaxseed oil, algae.

and

B vitamins

and

maintain nerve cell function and normal physiological metabolism, and are essential nutrients for eye development.

and

food sources: animal liver, lean meat, egg yolk, soybean, nuts, whole grain food, yeast, red beans, etc.

vitamin C

is an important nutritional component of the eye lens. The vitamin C contained in the eye lens is significantly higher than that in other tissues. The lens plays an important role in determining whether the eye can see objects.

and

food sources: fresh vegetables and fruits, such as persimmon pepper, chrysanthemum, balsam pear, spinach, fresh jujube, strawberry, citrus, etc.

calcium

calcium is called “second messenger” in nerve conduction, which shows its important role. Calcium deficiency of optic nerve will bring a series of problems, such as visual fatigue, blurred vision and so on.

and

food sources: milk, cheese, beans, seafood and green vegetables.

zinc

as a factor regulating gene expression can enhance the sensitivity of the optic nerve. Zinc deficiency will also affect the body’s absorption of vitamin A.

and

food sources: shellfish, seafood, red meat, animal viscera, nuts, grain germ, wheat bran, etc.

selenium

selenium exists in many tissues and cells of human body, but the content of eyes is the highest, so it is also one of the indispensable nutrients in eye development.

food source: selenium rich rice. The content of selenium in certain foods will vary according to different places of origin. For example, the selenium content of rice in low selenium areas can be less than 0.02mg/kg, while the selenium content of rice in high selenium areas can reach 20mg / kg, a ten thousand times gap.

lutein

lutein is a kind of carotene, which belongs to fat soluble vitamin. It appears yellow at low concentration and close to orange at high concentration. There is a large amount of lutein in the retinal macula of the eye. When light enters the eye, part of the blue light is absorbed by lutein, which can reduce the damage to the eye. In addition, lutein can remove the free radicals produced by light. A large number of studies have confirmed that after eating lutein rich foods or lutein supplements, the lutein concentration in the blood will increase, and the lutein in the macula will also increase, so lutein supplementation is effective for the human body. Food sources of

and

: lutein widely exists in plants, such as dark green vegetables, persimmon peppers, peas, broccoli, pumpkin, corn, eggs, etc.

and

are worth mentioning: in addition to the above 8 nutrients, which can promote baby’s eye development, we also need to know that eating too much sugar will affect baby’s vision!

sugar is an acid producing food, which can neutralize calcium, chromium and other basic elements in the baby’s body. Calcium and chromium are one of the materials to maintain eye elasticity. When the nutrition is balanced, the calcium and chromium elements in the body are also in a balanced state to maintain normal intraocular pressure; If calcium and chromium are insufficient, the elasticity of the eyeball wall will be reduced and the normal intraocular pressure cannot be maintained. Using the eyes for a long time can lengthen the eye axis and cause myopia.

in addition, the increase of blood glucose will accelerate the degeneration of ocular lens, cause the change of osmotic pressure of ocular lens and aqueous humor, increase the diopter, and lead to myopia; High blood sugar can cause diabetes, cause retinopathy and affect vision.
