Lutein and zeaxanthin are two important carotenoids. Apart from a slightly different atomic arrangement, they are very similar in structure. They are pigments produced by plants that give fruits and vegetables their yellow to reddish color. Both are known to protect the eyes and are potent antioxidants.
Lutein vs Zeaxanthin
Lutein, like zeaxanthin, has the effect of preventing cell aging and body (organ) aging. In the eye, zeaxanthin is mainly concentrated in the center of the macular area of the retina, while lutein is distributed throughout the retina. Since they have similar physiological functions and chemical structures, it is often easy to analyze and study them together as a substance.
Lutein and zeaxanthin have important antioxidant effects in the human body. Along with other natural antioxidants, including vitamin C, beta-carotene, and vitamin E, these important pigments protect the body from the damaging effects of free radicals.Free radicals are unstable molecules that can damage cells and play a role in many diseases. In addition to its important benefits for the eyes and vision, lutein also helps prevent atherosclerosis (fat buildup in the arteries).
Lutein, zeaxanthin, in the macula of the eye blocks blue light from reaching the underlying retinal structures, reducing the risk of light-induced oxidative damage that can lead to macular degeneration. Lutein and zeaxanthin can help prevent macular degeneration or slow the progression of the disease.
Foods rich in lutein tend to appear orange, green or yellow, and yellow pigment is the key to absorbing blue light. Blue light is very harmful to the eyes as it causes oxidation. The eye is a delicate structure, and free radical damage can lead to diseases such as cataracts and macular degeneration. For this reason, lutein is sometimes called the "eye vitamin." Zeaxanthin, also an antioxidant found in the retina and lens, is found in higher amounts in paprika, popcorn and marigold flowers.
