Have you nourished your child’s eyes?

Abstract: zinc plays a very important role in maintaining normal visual function. The content of zinc in eye tissue is the highest in the whole human body. Zinc deficiency may lead to night blindness, optic nerve diseases and optic nerve atrophy., With the change of diet structure, we eat more and more refined processed foods. This will lead to the loss of nutrients and even many additives. Long term consumption will cause human islet glands to secrete insulin, which will hinder the synthesis of growth protein factor-3., This will lead to the rapid development of teenagers’ eyeballs, the uncoordinated development of lenses, the gradual decline of vision, and even cause eye diseases such as vitreous opacity, macular degeneration, optic nerve atrophy and so on., Let’s first understand which nutrient deficiency is most likely to directly lead to myopia and eye problems, and then “suit the remedy to the case and make up for what is lacking”., Vitamin:, vitamin B1 deficiency in the eyes is manifested as blurred vision, dry eyes, etc. in severe cases, it will cause optic neuritis., Vitamin B2 deficiency in the eyes is characterized by decreased vision, fear of light, burning or foreign body sensation in the eyes., Vitamin C deficiency can increase the permeability of vascular wall, resulting in bleeding tendency. Vitamin C deficiency can cause bleeding of blood vessels and tissues in the eyes, and may also cause optic neuritis and retinitis., Trace elements:

with the change of diet structure, we eat more and more refined processed foods. This will cause the loss of nutrients and even many additives. Long term consumption will cause human islet glands to secrete insulin, which will hinder the synthesis of growth protein factor-3.

and

lead to rapid eye development, uncoordinated lens development, gradual decline of vision, and even eye diseases such as vitreous opacity, macular degeneration and optic nerve atrophy.

let’s first understand which nutritional elements are most likely to directly lead to myopia and eye problems, and then “suit the remedy to the case and make up for what is lacking”.

and

vitamins:

and

lack of vitamin B1. In the eyes, they are blurred and dry, which can cause optic neuritis.

and

lack of vitamin B2. In the eyes, they are characterized by decreased vision, fear of light, burning sensation or foreign body sensation.

vitamin C deficiency can increase the permeability of vascular wall, resulting in bleeding tendency. Vitamin C deficiency can cause bleeding of blood vessels and tissues in the eyes, and may also cause optic neuritis and retinitis.

trace elements:

trace elements zinc, copper, iron, magnesium and selenium are closely related to eye tissue.

zinc plays an important role in maintaining normal visual function. The content of zinc in eye tissue is the highest in the whole human body. Zinc deficiency may lead to night blindness, optic nerve diseases and optic nerve atrophy.

children lacking copper often have symptoms such as slow visual response, dull blink reflex, cataract, visual dysfunction and so on. Selenium deficiency in

and

will lead to crystal metabolism disorder, cataract and myopia.

protein:

protein is an important component of the eyeball. If the protein supply is insufficient for a long time, it will make the eye tissue aging, dysfunction and even blindness. Therefore, in order to protect the function of eyes, attention should be paid to ensuring the supply of protein in diet.

and

are the nutritional elements that can best improve children’s vision. What foods do you take from?

and

staple foods: yellow corn, millet, rhubarb rice and other yellow grains, containing lutein, zeaxanthin and carotene; Purple rice, black rice, red rice, red bean, black bean, etc. contain anthocyanins. In addition to white rice, white flour is the staple food every day, which is very unfavorable to the anti-aging of eyes. All these coarse grains and beans also contain vitamin E and vitamin B family required for anti fatigue of eyes.

and

fruits: focus on red, purple and blue fruits such as blueberries, blackcurrants, covered plates, cherries, mulberries and strawberries, which are rich in anthocyanins and vitamin C; Mango, papaya, citrus, etc. contain carotene and vitamin C.

vegetables: pay attention to spinach, rape and other dark green leafy vegetables, which contain a lot of lutein, carotene and vitamin C; There are also purplish red vegetables, such as purple cabbage, red amaranth and laver moss, which contain anthocyanins and vitamin C. Eating only light colored potatoes and white radishes is not enough to achieve the effect.

one of the most indispensable nutrients for the eyes is called “lutein”

. Lutein is a member of the carotenoid family, also known as “plant lutein”. It is the main pigment in the macular region of human retina and widely exists in vegetables, flowers, fruits and other plants.

lutein plays an important role in protecting the macula in the retina and is a key nutrient element to help eye development. Moreover, the human body cannot synthesize by itself and must be supplemented by ingesting lutein.

if the eyes lack lutein, it is easy to cause macular degeneration and blurred vision, and then appear symptoms such as vision degradation, myopia, retinopathy, and even blindness.

the most common foods rich in lutein in life are: spinach, lettuce, green cauliflower, cabbage, celery, okra, egg yolk, carrot, corn, pumpkin, papaya, melon, guava, orange, orange, peach, etc.

and

foods are rich in lutein, so why is the problem of lutein deficiency quite serious? The content of

and

lutein in food is not low, especially the content of dark green and red yellow vegetables is the highest. The lutein content of common foods is 17mg / 100g for carrots, 12mg / 100g for spinach, 13mg / 100g for pumpkin and 18mg / 100g for leeks.

according to the recommended amount given by the World Health Organization, 20 mg lutein per day is enough for normal people. If you convert 20mg lutein into food, it is actually just 117g carrot, 166g spinach, 153g pumpkin or 111g leek. Through calculation, we can find that it is only 2-3 liang of appropriate food to supplement sufficient lutein.

and lutein deficiency is a serious problem. Statistics gives an interesting answer: teenagers, pregnant women and the elderly are the main groups lacking lutein, and normal adults generally do not have the problem of lutein deficiency.

teenagers have a greater demand for lutein because of problems such as visual development and overuse of eyes;

pregnant women not only have to meet their own lutein needs during pregnancy, but also bear the lutein needs of the fetus, resulting in large lutein needs;

old friends are special, mainly because of poor fundus microcirculation and poor vascular permeability, resulting in poor lutein absorption.
