Xanthophyll ppt

Importance of xanthophyll to include in diet to improve health.

1. CAROTENOIDS CAROTENE XANTHOPHYLL

2. XANTHOPHYLL Xanthophylls (originally phylloxanthins ) are yellow pigments that occur widely in nature and of form one two major divisions of the carotenoid group; the other division is formed by the carotenes. The molecular structure of xanthophylls is similar to that of carotenes, but xanthophylls contain oxygen atoms, while carotenes are purely hydrocarbons with no oxygen. Xanthophylls contain their oxygen either as hydroxyl groups or as pairs of hydrogen atoms that are substituted by oxygen atoms acting as a bridge (epoxide). For this reason, they are more polar than the purely hydrocarbon carotenes, and it is this difference that allows their separations from carotenes in many types of chromatography. Typically, carotenes are more orange in color than xanthophylls .

3. Like other carotenoids, xanthophylls are found in highest quantity in the leaves of most green plants. The xanthophyll found in the bodies of animals, and in dietary animal products, are ultimately derived from plant sources in the diet . For example, the yellow color of chicken egg yolks, fat, and skin comes from ingested xanthophylls (primarily lutein, which is often added to chicken feed for this purpose). OCCURENCE

4. ROLE OF XANTHOPHYLL These are the yellow pigment of leaves and are classified as accessory pigments which absorbs the wavelength that chlorophyll cannot absorb. They serve as protection to excessive amount of sunlight to prevent further damage in the plant. Three kinds of Xanthophyll are :- Canthaxanthein , xeaxanthein , lutein. They are also considered as antioxidants. They play significant roles in human health, particularly the health of eyes, and are linked with reduced risk of age-related macular degeneration and cataracts.

5. Acting as antioxidant. Boosting your blood. Boosting your eyes. Boosting your immune system. Boosting your reproductive health. Preventing arthritis. PREVENTING GUM DISEASE:- If you suffer from gum disease then you might want to start eating more astaxanthin rich foods. Preventing mental disorders. HEALTH BENEFITS OF XANTHOPHYLL

6. Protecting against UV damage:- Ultraviolet (UV) rays are invisible rays of energy that come from the sun. They are extremely dangerous and can cause skin cancer. Canthaxanthein and lutein can keep all the body’s cell safe from harmful effects. Reducing unnecessary inflammation. Supports healthy growth. Supports pregnant and lactating women. Treating diabetes :- In Diabetes blood glucose levels become dangerously high as a result of your body’s cells failing to respond to insulin (a hormone which allows your body’s cells to take glucose from blood) or your pancreas failing to produce enough insulin. If left untreated, diabetes can seriously damage your body’s cells and vital organs. Fortunately, provisional evidence suggests that astaxanthin may be able to treat diabetes.

7. LUTEIN Lutein is a xanthophyll, synthesized only by plants like other xanthophyll. Lutein is obtained by animals by ingesting plants . In the human retina, lutein is absorbed from blood specifically into the macula lutea , although its precise role in the body is unknown . Lutein is also found in egg yolks and animal fats . Lutein is a lipophilic molecule, generally insoluble in water. Lutein has been used in food and supplement manufacturing as a colorant due to its yellow-red color . Lutein absorbs blue light and therefore appears yellow at low concentrations and orange-red at high concentrations

8. Lutein is a natural part of human diet when orange-yellow fruits and leafy green vegetables are consumed . Foods rich in lutein include broccoli, spinach, kale, corn, orange pepper, kiwi fruit, grapes, orange juice, zucchini, and squash. Cooked kale and cooked spinach top the list in richness of lutein. Many multivitamins contain lutein. They usually provide a relatively small amount of 0.25 mg per tablet People consuming 6.9 to 11.7 mg of lutein per day through diet had the lowest risk of developing AMD and cataracts. SOURCE OF LUTEIN

9. A ge-related macular degeneration ( AMD):- People who consume higher amounts of lutein in their diet have a reduced risk of developing AMD. However, increasing dietary intake of lutein might not reduce the risk of AMD in people who already have a high intake of lutein. Taking lutein supplements for up to 12 months can improve some symptoms of AMD, but it does not seem to prevent AMD from becoming worse. Cataracts. Some studies suggest that eating higher amounts of lutein might decrease the risk of developing cataracts. Also, early research suggests that taking lutein three times weekly for up to 2 years can improve vision in elderly people with cataracts. USES

10. Lutein is LIKELY SAFE when taken by mouth appropriately. Consuming 6.9-11.7 mg/day of lutein as part of the diet appears to be safe. Lutein supplements have been used safely in studies in doses up to 15 mg daily for up to 2 years . MARKET PREPARATION
