Spinach is rich in lutein. Lutein, also known as carotene, is widely found in vegetables, fruits and many other plants. As the main pigment, lutein plays an important role in the macular area of the retina (the innermost layer of the ocular wall). Macular area is the most sensitive part of human vision, full of cones. Therefore, lutein can effectively prevent macular degeneration, thus delaying the process of eye aging.
At the same time, spinach is also rich in vitamin B2 and beta-carotene.
Vitamin B2 is usually taken through food, such as spinach. Without vitamin B2, the cornea of the human eye is the most fragile. After conjunctival congestion occurs in human eyes, these blood vessels will grow and spread to the cornea, making the cornea without vascular tissue form many new blood vessels, which is easy to cause corneal edema; In more serious cases, it will lead to dry eyes and decreased vision. Therefore, eating more spinach can effectively reduce the production of red blood in eyes.
β -carotene is an excellent antioxidant and filter, so it can effectively prevent macular degeneration and cataract. At the same time, β -carotene can also prevent myopia and glaucoma in the general environment of eye fatigue.
To sum up, lutein can prevent age-related macular degeneration, glaucoma, myopia and dry eye, which is of great benefit to human eyes. You can eat more green leafy vegetables such as spinach.
