ROLE OF MACULAR CAROTENOIDS, VITAMINS & MINERALS IN EYE HEALTH.
By M.Rehan Sarfraz. Senior Product Manager.
Why eye supplements? AREDs. Antioxidants. How eye vitamins and minerals works? Phytonutrients. What are vitamins? Categories of vitamins What are minerals?
WHY EYE SUPLEMENT?As we age, the importance of vitamins increases drastically for following reasons
Our body starts to naturally get tired from working for so many years. Our body tends to have a harder time digesting and processing the vitamins that we do get in our regular diet. There are some vitamins and nutrients that help prevent the eye from certain age-related eye diseases, and that are not found in many common foods.
AREDs(Age Related Eye Diseases)AMD (Age Related Macular Degeneration) Cataracts Glaucoma DR (Diabetic Retinopathy)
AntioxidantsSlow or prevent damage to body cells May improve immune function and lower risk for infection and cancer Carotenoids Vitamin C Vitamin E Found in colorful fruits/veggies and grains5
Phyto plant Spark body processes that may fight, or reduce risk for some diseases Fruits/veggies Examples:
Carotenoids Lutein Lycopene Flavanols Prebiotics/probiotics Soyabeans7
Lutein or Zeaxanthin
Lutein, found in our retinas, is essential for healthy vision. Lutein and a related dietary carotenoid, zeaxanthin accumulate within the retina and imbue a yellow pigment that helps protect the eye. It lowers the risk of cataracts and macular degeneration (low lutein intake is implicated as a risk factor in age-related macular degeneration), and may also help to prevent or slow down atherosclerosis. Lutein is found in the red, orange, and yellow pigments of fruits and vegetables; for example, tomatoes, carrots, and squash. Green leafy vegetables such as spinach also contain high amounts of lutein.
Lutein or Zeaxanthin
Clinical research has determined that lutein along with zeaxanthin are two naturally occurring in the macular segment of the retina. The concentration of these two is so high in the macula (the retinal region responsible for fine visual activities), that the carotenoids are visible as a dark yellow spot, called the macular pigment, in normal, healthy retinas. They act like sunglass filters to protect the eye. **Research performed at Harvard Medical School has established that dietary zeaxanthin plays an essential role in protecting the retina of the eye from the damaging effects of light.9
Lutein or Zeaxanthin
Epidemiologic studies have shown that people with higher lutein/zeaxanthin levels have reduced risk for advanced stages of macular degeneration. **Blue-eyed individuals need more lutein and zeaxanthin because they have less of these protective pigments in their retinas. Again, dark, leafy greens are the dietary winner here, along with corn, nectarines, oranges, papaya and squash.
A Cutting Edge Carotenoid
It has been recently demonstrated that the MesoZeaxanthin present in the eye is a metabolic product that originates from lutein.
(Johnson EJ, Neuringer M, Snodderly DM)
It is the third most important xanthophyll pigment in human retinas and other species. Meso- Zeaxanthin is available in abundance in the fovea of macular region. It play a vital role in the increase of macular density of human retina when supplemented from outside as it is not present in normal diet.11
Established role of Vitamins & Minerals in Eye Health
Age-related eye diseases of significant public health impact include lens opacities (cataracts) and agerelated macular degeneration (AMD). A number of epidemiologic studies of dietary and serum levels of antioxidant vitamins suggest a protective role of antioxidants for these two ocular conditions.
**The Age-Related Eye Disease Study Research Group. A randomized, placebo-controlled, clinical trial of high-dose supplementation with vitamins C and E, beta carotene, and zinc for age-related macular degeneration and vision loss. AREDS Report No. 8. Arch Ophthalmol 2001;119:1417-1436.
What are vitamins?Complex substances that regulate body processes Coenzymes (partners) with enzymes in reactions
CategoriesFat-soluble Dissolve in fat Can be stored Water-soluble Dissolve in water Carried in bloodstream, not stored C and B-complex vitamins
A, D, E, K
A and D excess can be Excess amounts may harmful cause extra work on kidneys E and K usually not
Antioxidant, may lower risk for heart disease and some types of cancers Protects fatty acids and vitamin A
Vegetable oils Foods made from oil (salad dressing, margarine) Nuts Seeds Wheat Green, leafy veggies
Because of its antioxidant action, vitamin E helps protect against cataracts and age-related macular degeneration. A clinical study has showed that taking vitamin E can cut the risk of developing cataracts in half. Another study also showed that the combination of vitamins C and E had a protective effect against UV rays. Symptoms of vitamin E deficiency include muscle weakness, loss of muscle mass, abnormal eye movements, and impaired vision. Uveitis, an inflammation of the middle layer (uvea) of the eye, is another disorder for which the antioxidant vitamins C and E may be helpful. The uvea contains many of the blood vessels that nourish the eye; inflammation of this area can affect the cornea, the retina, the sclera, and other important parts of the eye.16
Produce energy Changes tryptophan (amino acid) into niacin
Liver Yogurt and milk Enriched grains Eggs Green, leafy veggies
Riboflavin (B2)Vitamin B2 deficiency includes. Eye inflammation. Vitamin B2 is important to the surface structures of the eye, preventing conjunctivitis and damage to the cornea. Sometimes, a lack of vitamin B2 produces red bloodshot eyes along with a burning sensation. The beneficial effects of vitamin B2 in reducing the risk of developing cataracts is more recently supported by scientific evidence,
Helps enzymes function normally Produces energy
Foods high in protein typically (poultry, fish, beef, peanut butter, legumes) Enriched and fortified grains
Cataracts -- One large population study found that people who got a lot of niacin in their diets had a lower risk of developing cataracts.19
Vitamin C(Vision Super Hero)
Helps produce collagen (connective tissue in bones, muscles, etc) Keeps capillary walls, blood vessels firm Helps body absorb iron and folate Healthy gums
Heals cuts and wounds Protects from infection, boosts immunity Antioxidant Citrus fruits Other fruits, veggies
DeficienciesRickets (children and vitamin D) Osteoporosis/ Scurvy (vitamin C)
Vitamin C(Vision Super Hero)Vitamin C has been linked to the prevention of cataracts One study has shown that taking 300 to 600 mg supplemental vitamin C reduced cataract risk by 70 percent Vitamin C also help in delay of macular degeneration, and eye pressure reduction in glaucoma patients..22
What are minerals?Regulate body processes Give structure to things in the body No calories (energy) Cannot be destroyed by heat
Categories of minerals
Calcium Phosphorus Magnesium Electrolytes (sodium, chloride, potassium)
Chromium Copper Flouride Iodine Iron Manganese Selenium Zinc24
MagnesiumPart of 300 enzymes (regulates body functions) Maintains cells in nerves, muscles Component of bones Best sources are nuts, and whole grains
ZincZinc, a trace element that influences cell metabolism through a variety of mechanisms. Zinc appears to play an integral role in maintaining normal ocular function. Zinc is present in high concentrations in ocular tissue, particularly in retina and choroid. **Zinc deficiency has been result in a variety of gross, structural and electro physiologic ocular manifestations.26
SeleniumSelenium is a trace mineral that our bodies need to boost immunity and fight off infections. It can also help prevent cataracts and macular degeneration by acting as an antioxidant that neutralizes free radicals that can damage the eye's lens and macula. **Studies have identified low selenium levels in cataract sufferers. Selenium also helps your body to absorb vitamin E. Fish, shellfish, red meat, grains, eggs, chicken, liver, and garlic are all good sources of selenium.
Copper. This mineral produces collagen, which is a component of the connective tissues, and it keeps cell membranes healthy. Both of which are crucial to eye health.
