Lutein as a Vitamin

Found in some fruits and vegetables, and egg yolk, the lutein is the nutrient along with number of actively useful results. He is the member of carotenoid classes, a class of the chemicals in terms of vitamin A. When beta-carotene, a precursor of vitamin A, carotenoids may be best known, there are about 600 others, whose effects have not been widely studied. In addition to lutein and include alpha-carotenes, lycopenes, zeaxanthin as well as beta-cryptoxanthins. Within the world of plants, carotenoids like lutein helps to deliver the colors to the sweet potato, carrot as well as other fruits and the vegetables. In humans, lutein and zeaxanthin comprise most of the pigments at the middle of your retina at places in which vision sensitiveness is higher.

Directed by Eliot Berson, MD, Eye and Ear Infirmary, Massachusetts at Harvard Medical School, researchers recruited 225 non-smokers with retinitis pigmentosa between 18 and 60. Participants were at randomly assigned to accommodate vitamin A alone (15 000 IU retinol palmitate) or vitamin A and lutein (12 mg daily) for four years.

Although no significant effects were observed  of its decrease in vision within two groups was a significant reduction in the incidence loss of vision in mid-peripheral  area observed.

According to the researchers, is the average mid-peripheral sensitivity to a patient of 40 375 dB. People take supplements of lutein have lost an average of 27 dB  every year,when the other unite lost 34 dB  every year, researchers noticed.Lutein is the member of carotenoid family, a unite of strong antioxidants that is also contains beta-carotene,  lycopene and zeaxanthin alpha-carotene,. Lutein is xanthophyll, And it is one type of the carotenoid seen in high concentrations dark green like leafy vegetable and egg yolks. Like other known as  beta-carotene and carotenoids alpha-lutein are strong antioxidant it gives food a red, orange or yellow Unlike both alpha-and beta-carotene, lutein can be converted by the body into vitamin A.

Lutein helps to protect your skin and eyes from ultraviolet damage, its color is yellow  blocks of blue (UV) absorption. The macula of the retina is rich in lutein, it is  not only contribute the eyes and UV protection against sunlight, but also appears to reduce the risk of developing macular degeneration (AMD). AMD is one of major reason of blindness in ageing. In the year of 2004, the antioxidants lutein supplementation trial (LAST) showed that lutein supplementation can help to reverse symptom of the macular degeneration. On its study, veterans was given carotenoid supplements and its determine whether the improvement in vision. Lutein supplements improves symptoms of AMD among participants.Lutein is not considered essential for good health, did not place a Recommended eating habits allowance (RDA). moreover, most researchers concluded that diets rich in carotenoids play an important role in preventing various diseases, including heart disease, stroke, and lung, stomach and cervical cancer. Although not permitted as the dietary supplements from the FDA, lutein has been ubiquitous within food. It can perform a vital part in preserving the vision as well as prohibiting eye diseases such as cataracts and AMD, 2 main reasons of the vision losses among adults. Carotenoids can achieve this by protecting the ocular tissues against damage from free radicals and protect the eyes against sunlight potentially destructive. Research also shows that getting enough lutein may reduce the chances of the colon cancer as well as the heart diseases.
