Now adults and children are faced with computers and mobile phone screens every day. Their eyes are dry and fatigued. In particular, there are more and more young people with myopia. In the face of dry eyes, fatigue and other symptoms, in addition to eye drops treatment, eating these foods is good for the eyes. Here's a look at what foods are good for the eyes? Dry eyes eat chives Leeks are called spring vegetables, and they are also known as wild herbs, vegetables, nursery herbs, and cabbages. They grow in fields, roadsides, and courtyards. They have the effects of heat-quenching, blood-clearing, eyesight, and diuretic swelling. Leek contains a lot of carotene, B vitamins and vitamin C, calcium and iron content is also high. White-collar office workers are prone to dry eye disease. Leeks are rich in carotenoids. Eating leeks can prevent dry eyes and reduce dryness and discomfort. Due to the cool nature of leeks, people with weak spleen and stomach are unfit for human consumption, especially if the stools are not shaped and often defecated. Eye fatigue eating sweet potato When people reach a certain age, their eyes will be prone to fatigue, sometimes they will feel pain, eyes will not open, and vision will decline. "The eye is a mirror of the internal organs." The failure of the eyes is a sign of internal organs, especially the deterioration of the liver and kidneys, and aging. Therefore, to improve the function of the eye, the precondition is to restore the function of the internal organs. In order to enhance the liver and kidneys and function, in addition to the prevention of excessive drinking and excessive fatigue, it can also be solved by ingesting beneficial foods. The most representative food here is sweet potato. Sweet potato has the function of "repairing and replenishing qi", which can improve the function of the digestive organs, nourish the liver and kidney, and restore the body's weakness. Sweet potatoes can also be effective in treating hepatitis and jaundice. According to nutritional analysis, sweet potatoes are rich in dietary fiber, vitamins, and minerals. The method of eating sweet potatoes is various and can be directly cooked or eaten, or made into dry spots. Sweet potato flour can be dissolved in milk or soy milk in Beverage Service. The yellower yolk is better for eye health Eggs contain abundant minerals such as protein, fat, yolk, lecithin, vitamins and iron, calcium, potassium, lutein, and zeaxanthin. Eggs consist of eggshells, egg yolks, egg whites and egg laces, which have different nutritional values, among which egg yolk has the highest nutritional value. Some people do not like to eat egg yolks, especially those who are obese or those who are losing weight, and they worry that they will gain weight after eating yolks. There is also a high cholesterol in the egg, which is thought to increase blood fat and cause hardening of the blood vessels. Therefore, most people are aware of it, and they also worry that eating yolk increases cholesterol, so eating only egg white does not eat yellow. The reason for this concern is because they don't know that the egg yolk is rich in nutrients. Among the components of the egg yolk there are two kinds of nutrients that are specifically mentioned: lutein and zeaxanthin. People who care about the eyes should pay attention to the fact that lutein and zeaxanthin have a close relationship with eye protection. The effects of lutein and zeaxanthin have a strong anti-oxidant effect, and have a special eye protective effect. The human eye's imaging site is the retina, and the retina has a "macular spot" with yellow nutrient sources, lutein and zeaxanthin. These two types of nutrients can reduce the damage of ultraviolet rays to the eyes, delay the aging of the eyes, and prevent eye diseases such as retinal macular degeneration and cataract. Eat spinach eyes "bright" The eyes are one of the hardest organs in the human body and are therefore particularly prone to tiredness due to hard work. Aging eyes also need food supplements. Recently, a study by the University of Manchester in the United Kingdom confirmed that spinach is one of the best sources of lutein, and lutein is very effective in preventing "retinal macular degeneration" caused by aging eyes. The large amount of lutein in deep-green leafy vegetables such as spinach is very helpful in preventing cataracts. According to research, green leafy vegetables are also a good source of vitamin B2 and beta-carotene. When vitamin B2 is sufficient, the eyes are not easily covered with bloodshots; while beta-carotene can be converted into vitamin A in the body to prevent "dry eye disease" embolism. The benefits of spinach in green leafy vegetables do not stop there. It is rich in potassium, calcium and magnesium. It helps the eye muscles to increase their elasticity and is not prone to myopia. People all know that people with calcium deficiency have poor eyeball flexibility and the eye shaft is prone to stretching. Researchers also said that the daily life of rice, roast pork, braised fish, sweet drinks, and desserts will cause serious loss of calcium in the human body. If you can eat less meat, eat more spinach, you can make up for this deficiency, and greatly improve the flexibility of the eye muscles. Regular use of eyes, eat more yellow corn Due to aging, macular degeneration, loss of vision, and even blindness occur when the fat in the macula is oxidized and damaged. Lutein and zeaxanthin, on the other hand, can absorb harmful light entering the eyeballs and maintain the health of the macula with its powerful anti-oxidant effect. However, it should be noted that only yellow maize has lutein and zeaxanthin, but white corn does not. Therefore, taxi drivers, primary and secondary school students, editors, writers, etc., who often use their eyes, should eat some yellow corn.
