Aging eyes? Dark vegetables to help

Abstract: at present, the incidence of age-related macular degeneration has become the most common cause of blindness in the adult population in the west, with an incidence rate of about 1%. Experts said that there is no effective treatment for this eye disease, so prevention is very important, and this prevention should start from an early age., In recent years, the nutrition department has paid attention to the protection and development of infants’ vision, and the incidence rate of age-related macular degeneration. To prevent and treat macular disease, you should eat more dark vegetables, especially spinach, corn and pumpkin, which can resist eye aging., Eat more dark vegetables. The macula is the patron saint of the eye. The macula is an important part of the eye, located in the center of the fundus retina. Among the light entering the retina, blue light has the strongest energy. It can penetrate the eyeball directly to the retina and macula. Normal macula can filter out blue light and avoid damage to eyes caused by blue light and free radicals produced by blue light., If there is no normal macular area, visual function will gradually decline, or even blindness. Take age-related macular degeneration (AMD) as an example. This eye disease is age-related and mostly starts in the middle-aged and elderly between the ages of 50-60. Due to the deficiency of lutein in macula caused by factors such as heredity, diet, environment (such as pollution) and age growth, the eyes will inevitably be damaged by blue light in the sun and free radicals from various reasons, and finally cause vision loss, and this vision damage is irreversible., At present, the incidence of age-related macular degeneration has become the most common cause of blindness in the Western adult population, with an incidence rate of about 1%.

the macula is the patron saint of the eye

the macula is an important part of the eye, located in the center of the fundus retina. Among the light entering the retina, blue light has the strongest energy. It can penetrate the eyeball directly to the retina and macula. Normal macula can filter out blue light and avoid the damage of blue light and free radicals produced by blue light to the eyes.

if there is no macular area with normal function, the visual function will gradually decline and even become blind. Take age-related macular degeneration (AMD) as an example. This eye disease is age-related and mostly starts in the middle-aged and elderly between the ages of 50-60. Due to the lack of lutein in macula caused by factors such as heredity, diet, environment (such as pollution) and age growth, the eyes will inevitably be damaged by blue light in the sun and free radicals from various reasons, and finally cause vision loss, and this vision damage is irreversible. At present,

and

have become the most common causes of blindness in Western adults, with an incidence rate of about 1%. Zhao Yongyi said that there is no effective treatment for this eye disease, so prevention is very important, and this prevention should start from childhood.

dark vegetables can “nourish” the macula

research has found that the cone cells in the macula are rich in lutein, which makes the macula filter out blue light, resist free radicals and prevent damage to the eyes. However, lutein is not classified into the six nutrients we call, but belongs to one of the carotenoids in the “phytochemicals”.

and

are also lutein and zeaxanthin in our food. Dark green, yellow and orange vegetables and egg yolks contain lutein and zeaxanthin, among which dark green vegetables such as spinach and cabbage are rich.

in fact, spinach, pumpkin, pea, egg yolk and corn are common in the market. Rich in zeaxanthin are sweet corn, persimmon, mustard, lettuce and so on.

and

in addition, there has been the saying of “eyesight” of medlar in China since ancient times. “Lycium barbarum” is a solanaceous plant with high zeaxanthin content, so Lycium barbarum has a certain truth.

and

are key groups that need lutein supplementation.

and

should pay attention to eye protection since childhood. In addition to reducing eye fatigue, they should also pay attention to eye nutrition. Zhao Yongyi said that there are four groups of people who need to supplement lutein.

infant. Incomplete eye development in infancy is the stage most likely to cause abnormal eyes and vision in life, and is most vulnerable to the attack of blue light. Lutein is highly concentrated in the macular area of the retina of infants, protecting the retina of infants from blue light damage, helping to protect the retina from oxidative damage, and acting as a barrier for the young eyes of infants. The World Health Organization has set an acceptable daily intake (ADI) – 2mg / kg (infant weight).

old people. The intake of lutein and zeaxanthin can reduce the risk of senile macular disease.

pregnant women. As the body needs more nutrients, it may not take enough lutein.

and

are engaged in outdoor sports and outdoor workers. Because it takes a long time to receive sunlight, there is a great chance of eye macular damage.
