Can eyes be "nourished"? Many people might just laugh it off, but this is actually a serious scientific topic. Fifty percent of urban high school students are nearsighted
Those who have been to the countryside know that rural children seldom wear glasses. Currently, the incidence of myopia among students in our country's cities is astonishingly high. According to statistics from the Ministry of Health, the myopia rate among high school students in some large and medium-sized cities in coastal provinces can be as high as 50%.
So why is it that, despite being students, the myopia rate in rural areas is far lower than in cities? In the past, some in the medical community believed: because the rural field of view is much broader than in the city, rural students often look at distant objects, so their vision is naturally better than that of urban students. However, this explanation is unconvincing. Urban children consume less lutein
In recent years, Western nutritionists have finally unraveled this mystery through in-depth research. It turns out that the occurrence of myopia is closely related to insufficient intake of a nutrient called "lutein".
Lutein belongs to the "carotenoid" family and is found in higher concentrations in fresh green vegetables and citrus fruits. According to scientific research, lutein plays an important protective role for the "macula" in the retina. A lack of lutein can easily lead to macular degeneration and blurred vision. Eat more citrus to prevent vision degeneration
Rural children consume a sufficient amount of lutein because they eat green vegetables picked directly from the fields every day. In contrast, urban children usually eat high-protein, high-nutrient foods and rarely eat fresh green vegetables, so their lutein intake is much lower than that of rural children. This is the main reason for the huge difference in vision between children in urban and rural areas.
In view of this, nutritionists recommend: eat more citrus fruits daily to prevent vision degeneration.
