What to eat is good for your eyes. Myopia is not convenient for our life, so it is very important to protect your eyesight. So let's follow me to see the knowledge about what to eat is good for your eyes. I hope it will help you.
What to eat is good for your eyes 1 spinach
Spinach can prevent some eye diseases. A carotenoid called lutein found in spinach can prevent cataracts and macular degeneration.
fruit
Fruits rich in vitamin C, such as kiwi fruit, orange and wolfberry fruit. Vitamin C can eliminate free radicals that can cause harm to eyes.
bean products
Fatty acids, vitamin E and natural anti-inflammatory agents in bean products are very beneficial to the eyes. Soy milk, soybeans and soy cheese are good for eye health. Olive oil is as good for your eyes as foods rich in vitamin E such as cereals.
garlic
Garlic is an excellent food for improving eyesight. The sulfur in garlic can stabilize the lens and make it more resilient. In addition, onions rich in sulfur are also good for eyesight.
apricot
Vitamin A contained in apricots can avoid eye damage caused by free radicals. Apricots also contain some carotenoids that are responsible for improving vision.
(hen's) egg
If you are a person who likes eating eggs very much, congratulations. Eggs are very good for eyesight. Eggs contain cysteine, sulfur, lecithin, amino acids and lutein, which can avoid cataracts.
Salmon and sardines
They are rich in omega-3 fatty acids, which are very good for eyesight. The main source of omega-3 fatty acids is fish, while salmon and sardines are rich in DHA, an omega-3 fatty acid.
broccoli
Broccoli can not only improve eyesight but also prevent cataracts. Broccoli contains lutein and zeaxanthin (a phytonutrient antioxidant in carotenoids). This substance is very good for the lens. These carotenoids can protect eye cells from the stress caused by free radicals.
Dark chocolate
Flavonoids in dark chocolate can protect eye blood vessels, thus strengthening cornea and lens. It should be emphasized that only pure dark chocolate can achieve this expected effect.
What to eat is good for eye vision? 2 What nutrients determine good vision?
Pre-anthocyanin
It is a pure natural anti-aging nutrient. Existing studies have proved that proanthocyanidins are the most effective antioxidants discovered by human beings today, and their antioxidant performance is 50 times higher than that of vitamin E and 200 times higher than that of vitamin C.. Different from other antioxidants, proanthocyanidins can directly protect the brain and optic nerve system through the blood-brain barrier. It can be detected in the blood 20 minutes after taking it. The main function of proanthocyanidins is to soften capillaries, eliminate eye fatigue and improve vision. In addition, it can also assist in the treatment of myopia, amblyopia, cataract, glaucoma and other eye diseases.
Lutein and zeaxanthin Lutein are carotenoids. In our daily diet, food contains more than 50 kinds of carotenoids, but only lutein and zeaxanthin will accumulate in the macular part of the retina, so it is also called macular pigment. Retina and macula are responsible for feeling images, fine vision and clarity, and they are needed for daily color discrimination and reading literacy. If lutein and zeaxanthin are lacking in macula and retina for a long time, it will affect vision; Those with severe symptoms may even be blind.
In addition, lutein and zeaxanthin are the only nutrients that can absorb blue light and ultraviolet light, which can improve eye fatigue and reduce the phenomenon of "watery eyes"; They are also powerful natural antioxidants, which can resist the damage of free radicals to the eyes and protect them.
0 ~1year is the period of rapid eye development, so it is especially necessary to supplement nutrition. However, the content of lutein in breast milk is seriously insufficient, and the human body itself can't synthesize lutein at all. Therefore, milk powder or complementary food with lutein should be selected for the baby.
The antioxidant capacity of anthocyanin anthocyanin is about 50 times that of vitamin E. Studies have proved that anthocyanins can strengthen microvascular elasticity, promote microvascular blood circulation, maintain normal eye pressure, eliminate eye muscle fatigue and edema, and improve vascular dark circles; It can activate and accelerate the regeneration of rhodopsin, promote visual acuity and improve night blindness; Can effectively inhibit the enzymes that destroy eye cells; It can make the retina adapt to the change of light, improve the eye's recognition in the dark, protect the eyes from free radicals and prevent eye degenerative diseases.
astaxanthin
Astaxanthin, a red carotenoid found in the shell of crayfish, has strong oxidation resistance, which can effectively remove oxygen free radicals in cells, enhance cell regeneration ability, maintain body balance and reduce the accumulation of aging cells, thus protecting skin health, promoting hair growth, resisting aging, relieving exercise fatigue and enhancing vitality. Astaxanthin easily passes through the blood-brain barrier and cell membrane, which can effectively prevent the oxidation of retina and the damage of photoreceptor cells. It can also protect the central nervous system, especially the brain. In addition, it can also prevent ultraviolet radiation and cardiovascular diseases.
Vitamin
vitamin C
Vitamin C comes from vegetables and fruits, especially dark green vegetables. Vitamin c can weaken the damage of light and oxygen to the lens of the eye, thus delaying the occurrence of cataract.
vitamin A
Vitamin A plays a very important role in maintaining normal vision. Because it is an important raw material for synthesizing visual photosensitive substances. If vitamin A is lacking, the eye's ability to feel weak light will decrease, and it is impossible to see objects clearly in the weak light environment.
Vitamin b
Vitamin B is helpful for promoting normal growth and development of human body, improving optic nerve function and improving vision and energy. Lack of vitamin B can lead to lack of concentration and dull eyes. Vitamin B can improve eyesight, relieve eye fatigue and treat eye diseases. It can also promote development, improve human body's absorption of iron, strengthen human immunity and eliminate free radicals.
taurine
Taurine is abundant in human retina, which can improve visual function and promote the development of retina. At the same time, it can also improve the self-repair ability of cornea and fight against eye diseases. When the taurine content in retina decreases, the structure and function of retina may be disordered, which may affect vision.
calcium (Ca)
Calcium is closely related to eyeball composition. Teenagers who are at the peak of growth need more calcium. If we don't pay attention to calcium supplement, it will not only affect the development of bones, but also reduce the elasticity of the developing eyeball wall-sclera and increase the internal pressure of the lens, which will lead to the elongation of the anterior and posterior diameter of the eyeball and lead to myopia.
chrome
Chromium can activate insulin and make insulin exert its maximum biological effect. If the chromium content in human body is insufficient, the function of insulin in regulating blood sugar will be hindered, and the osmotic pressure of plasma will increase, which will lead to the increase of osmotic pressure and diopter of eyeball lens and aqueous humor, thus inducing myopia.
zinc (Zn)
Zinc is mainly distributed in bones and blood in human body, and zinc is also contained in corneal epidermis, iris, retina and lens. Zinc participates in the metabolism and transport of vitamin A in the eye, and maintains the normal tissue state of retinal pigment epithelium. Zinc deficiency can lead to visual impairment.
