How to correctly understand the role of lutein?

Lutein is a widely present in vegetables, flowers, fruit and other natural substances in plants living in" Class carrot "family matter, the medical experiments show that plants contain lutein is an excellent natural anti- oxidants in the food by adding a certain amount of lutein may prevent cell aging and the aging body organs, but also the prevention of age-related macular degeneration eye vision loss and blindness caused by lutein (U.S. time capsule of lutein) can be will absorb the light energy is passed to chlorophyll a, speculated that light oxidation, light damage to a protective effect, the human eye is lutein macular pigments in the region. tools / materials lutein steps / methods Lutein is a important antioxidant for the carotenoid family (a group of plants found in the natural fat-soluble pigments), a member, also known as "plant progesterone" in nature with zeaxanthin co-exist. The main pigments of retinal : lutein and zeaxanthin form of vegetables, fruits, flowers and other plant pigments, the main component, is also a human retinal macular region * the main pigment. The human eye contains high levels of lutein, this element is the human body can not produce and must be supplemented by the intake of lutein, if the lack of such elements, the eye will be blind. lutein in the macula of the retina has an important protective role, the lack of easy to lead when macular degeneration and blurred vision. then there vision degeneration, myopia and other symptoms. lutein is the precursor of NA, in the human body can be transformed into VA. lutein for the eyes is the main physiological function as antioxidants and light protection. optic non-renewable, vulnerable to harmful free radicals injury, the role of the antioxidant lutein can inhibit the formation of harmful free radicals. lutein can absorb a lot of blue, blue wavelengths of visible light and ultraviolet light close to visible light can reach the retina is the most potentially harmful one kinds of light. In the sensitive cells to reach the retina before the light go through the highest lutein accumulation area at this time if, as the lutein macular rich will be able to minimize such damage. protect your eyes from the light damage, delay aging and prevent eye disease: the sun's ultraviolet rays and blue light entering the eye will produce a large number of free radicals, leading to cataracts, macular degeneration, cornea and lens UV filter normally be out, but has to wear blue direct the eye through the retina and macula, while lutein in the macula filters out blue light, to avoid damage to the eyes blue. macular region particularly vulnerable to the outer layer of fat to oxidative damage in sunlight, so prone to degradation in the region . cataract blindness is the world's major diseases of the eye, the latest studies have shown that by increasing the intake of lutein can achieve the purpose of birth rate, now that the mechanism for the lower macular pigment density and higher in the elderly closely related to the visual density of the lens, while the higher visual density of lens cataract is considered to be the obvious features. antioxidant, helps prevent hardening of the body aging caused by cardiovascular, coronary heart disease. Recent studies show that lutein Early atherosclerosis process has delayed effect. mainly the main road artery intimal thickness changes and the blood relationship between lutein content. lutein in the blood content is low, can easily cause thickening of artery walls, along with lutein content increased gradually trend lower arterial wall thickening, arterial embolization also significantly reduced. Meanwhile, the artery wall cells in the leaves yellow cable can reduce LDL cholesterol oxidation. Reference view/481452.htm
