Commit error: The Importance Of Light And Pigments Used

College engineering essay examples

Good nutrition is important to keep your eyes healthy and functioning their best throughout your lifetime. Two very important eye nutrients that may reduce your risk for macular degeneration and cataracts have names you may not be familiar with: lutein LOO-teen and zeaxanthin zee-ah-ZAN-thin. Lutein and zeaxanthin are two types of carotenoids kuh-RAH-teh-noidswhich are Pigmets to red pigments found widely in vegetables and other plants.

Though lutein is considered a yellow pigment, in high concentrations it appears orange-red. Cooked spinach is one of the best natural food sources of lutein and zeaxanthin. In nature, lutein and zeaxanthin appear to absorb excess light energy to prevent damage to plants from too much sunlight, especially from high-energy light rays called blue light. In addition to being found in many green leafy plants and colorful fruits The Importance Of Light And Pigments Used vegetables, lutein and Ued are found in high concentrations in the macula of the human eyegiving the macula its yellowish color.

In fact, the macula also is called the "macula lutea" from the Latin maculameaning "spot," and luteameaning "yellow".

Recent research has discovered a third carotenoid in the macula. Called meso-zeaxanthin, this pigment is not found in food sources and appears to be created in the retina from ingested lutein. Lutein and zeaxanthin appear to have important antioxidant functions in the body. Along with other natural antioxidants, including vitamin Cbeta-carotene and vitamin Ethese important pigments guard the body from damaging effects of free radicals, which are unstable molecules that can destroy cells and play a role in many diseases. In addition to important eye and vision benefits, lutein may help protect https://amazonia.fiocruz.br/scdp/blog/woman-in-black-character-quotes/overcoming-fear-of-failure-start-right-now.php atherosclerosis buildup of fatty deposits in arteriesthe disease that leads The Importance Of Light And Pigments Used most heart attacks.

It is believed that lutein, zeaxanthin and meso-zeaxanthin in the macula block blue light from reaching the underlying structures in the retina, thereby reducing the risk of light-induced oxidative damage that could lead to macular degeneration AMD. A number of studies have found that lutein and zeaxanthin either help prevent AMD or may slow progression of the disease:. The macular pigment is believed to offer protection against the development of macular degeneration.

What is Luster and Glitter?

Studies published in American Journal of EpidemiologyOphthalmology and Archives of Ophthalmology found higher levels more info lutein and zeaxanthin in the diet are associated with a lower incidence of AMD. Two studies published in Investigative Ophthalmology and Visual Science found that eyes with greater levels of macular pigments were less likely to have or develop macular degeneration. In research published in Archives of Biochemistry and Biophysicsthe study authors conclude that lutein, zeaxanthin and meso-zeaxanthin filter short-wavelength light and prevent or reduce the generation of free radicals in the retinal pigment epithelium and choroid.

They also suggest that a mixture of these carotenoids is more effective than any one of the individual carotenoids at the same total concentration. In a study published in the journal The Importance Of Light And Pigments Usedparticipants with early AMD who consumed 8 mg per day of dietary zeaxanthin for one year improved their night driving and their visual acuity improved an average of 1. AREDS2 was a follow-up to the original 5-year AREDS study published inwhich Was Bunker A Bunker Not The use of a daily antioxidant supplement containing beta-carotene, vitamin C, vitamin E, zinc and copper reduced the risk of progressive AMD by 25 The Importance Of Light And Pigments Used among participants with early and intermediate macular degeneration. The goal of AREDS2 was to evaluate the effect of other nutrients — including lutein and zeaxanthin — on the prevention of AMD and other age-related eye diseases.

AREDS2 also investigated the effect of removing beta-carotene from the AREDS supplement, since supplementation of this vitamin A precursor has been associated with increased risk of certain cancers among smokers and previous smokers. The AREDS2 results revealed study participants with early signs of macular degeneration who took a modification of the original AREDS nutritional supplement that contained 10 mg lutein and 2 mg zeaxanthin and no beta-carotene every day for the 5-year study period had a 10 to 25 percent reduced risk of AMD progression.

Study participants whose diets contained the lowest amounts of foods containing natural lutein and zeaxanthin experienced the greatest AMD risk reduction from taking the daily nutritional supplement. While AREDS2 and other studies provide evidence that Pigmwnts The Importance Of Light And Pigments Used zeaxanthin may play a role in preventing macular degeneration or at least reducing the risk of progression of AMDit's less clear if these carotenoids help prevent cataracts. Research published in Archives of Ophthalmology suggests women whose diets include high amounts of healthful foods containing lutein, zeaxanthin and other carotenoids have a lower risk of cataracts than women whose PPigments contain lower amounts of these nutrients. In AREDS2, however, supplemental lutein and zeaxanthin had no effect on cataract risk or progression.

Eyefoods: A Food Plan for Healthy Eyes is a new book designed to help you improve the health of your eyes. Written by eye doctors Laurie Capogna, OD, and Barbara Pelletier, OD, the book describes nutrients such as lutein, zinc and vitamin C and tells you which foods they are found in and how much you need each day to help maintain healthy eyes. The book also presents research that links good nutrition to reduced risk of eye disease, as well as quick recipes for incorporating eye-healthy vitamins and minerals in your daily diet. The text is https://amazonia.fiocruz.br/scdp/blog/culture-and-selfaeesteem/please-open-your-bibles-on-the-believer.php to understand, and the big, colorful food photos will inspire you to eat better.
