The growth and metabolism of the human body are inseparable from vitamins. Similarly, the eyes also have their own essential vitamins, that is, lutein.
Those who have studied medicine know that age-related macular degeneration, retinitis pigmentosa, diabetic eye disease, vitreous opacity and other eye diseases are all related to lutein deficiency. (There are many people playing mobile phones and computers. Drivers, teachers, and patients with high myopia are all high-risk groups of blindness.)
Supplementing lutein in time when the eyes are tired every day can provide eye nutrition, thereby effectively preventing vision loss and blindness caused by cataract glaucoma, vitreous opacity, presbyopia, and age-related macular degeneration.
What is lutein?
Lutein (Lutein) is a carotenoid, it and β-carrot are relatives; the difference is that β-carrot can be converted into vitamin A in the body, lutein does not have this ability.
Vitamin A is closely related to the eyes. A severe deficiency may cause night blindness, while a slight deficiency may cause dry eyes, which may cause stinging and burning eyes.
Lutein cannot be converted into vitamin A, so what does it have to do with the eyes?
It turns out that it is very rich in the macular area and retina of the eye, like a "filter" that can absorb blue light that is harmful to the eyes; In addition, as an antioxidant, it can also reduce the damage of harmful free radicals to the optic nerve, so the eyes contain enough lutein to really protect the eyes.
How to take lutein supplement?
【Kiwi】
According to research, kiwi fruit is the most abundant food containing lutein, which can effectively maintain eye health and prevent eye fatigue.
Moreover, kiwi also contains antioxidants - vitamin C, which can eliminate the abnormal accumulation of oxides in the human body and avoid the damage of eye tissue.
【Corn】
The macular pigment composed of lutein and zeaxanthin is a pair of "natural sunglasses" in our body, which can always filter strong light to protect the eyes.
Corn has the highest content of these two pigments of all foods, which protect the light-sensitive area of the eye called the macula, preventing the development of age-related macular degeneration and cataracts.
【Dark green and yellow-orange vegetables】
The human body cannot synthesize lutein, and the required lutein can only be obtained from foods or supplements rich in lutein. Dark green, yellow, and orange vegetables all contain lutein, and dark green vegetables such as spinach and cabbage are rich in lutein.
Secondly, pumpkin, peaches, peppers, mangoes, and citrus are rich in lutein esters, which are precursors of lutein. Fruits such as mangoes, grapes, oranges and orange juice, tomatoes are also rich in lutein.
