Among the dark green vegetables we often eat, there is such an ingredient, which is called "eye gold", which has a good eye protection effect, that is, lutein.
Many people use anti-blue light glasses to protect their eyes, because the blue light emitted by many electronic screens can penetrate the eye ball and reach the retina and macula, thus causing damage to the eyes.
However, lutein in the macula can filter out blue light and is a natural eye protection ingredient.
Lutein acts as an antioxidant and promotes the regeneration of rhodopsin in retinal cells, which plays a key role in the formation of eye vision.
The outer layer of fat in the macular area is particularly susceptible to oxidative damage from the sun's rays, so this area is highly susceptible to degeneration.
After eating lutein-rich foods, the concentration of lutein in the blood will increase, and the lutein on the retinal macula will also increase, thereby delaying the occurrence and development of age-related macular degeneration.
The recommended intake of lutein in the Dietary Reference Intakes for Chinese Residents is 10 mg per day, and the tolerable maximum intake is 40 mg per day.
The body's demand for lutein can be met through dietary supplements.
In general, lutein is higher in dark green, yellow, and orange vegetables.
Some fruits are also rich in lutein, such as mangoes, grapes, oranges, etc.
