Natural Remedies for Macular Degeneration
Although taking a simple multivitamin is unlikely to hurt your health, does taking vitamin supplements improve your health if you already have a good diet In a review of carefully controlled research studies on the impact of vitamin supplements on cancer, heart disease, cataracts, or age-related macular degeneration and hypertension, the National Institutes of Health concluded that the evidence is insufficient to prove the presence or absence of benefits from use of multi-vitamin or mineral supplements to prevent cancer and chronic disease (Huang et al. 2006, National Institutes of Health 2007).
Over 250 epidemiological studies of cancer or heart disease risk have shown that high dietary intakes of beta-carotene rich fruits and vegetables were associated with lower risk of premature disease and death (Ziegler, 1991). Beta-carotene was linked to the prevention of cancer, heart disease, macular degeneration, and premature aging in these studies (Burri, 1997 Erdman et al., 1996). Cell culture, animal, human, and in vitro studies showed that beta-carotene was an effective antioxidant (Dixon et al., 1998 Dugas et al., 1999 Lin et al., 1998 Lowe et al., 1999). Furthermore, it was more powerful in gap-junction formation than lycopene (Bertram et al., 1991 Zhang et al., 1992), and inhibits cholesterol synthesis by the same mechanism as lycopene (Aviram and Fuhrman, 1998 Fuhrman et al., 1997).
Food contains much more than nutrients Science is beginning to uncover the benefits of other substances in food phytonutrients (including fiber), omega fatty acids, conjugated linoleic acid, and pre- and probi-otics, to name a few. Described as functional, these substances do more than nourish you. They appear to promote your health and protect you from health risks related to many major health problems, including heart disease, some cancers, diabetes, and macular degeneration, among others.
Electron from body cells to become stable. Over time, that may lead to cell dysfunction and contribute to the onset of health problems such as cancer, artery and heart disease, cataracts, age-related macular degeneration, diabetes, Alzheimer's disease, and some deterioration that goes with aging. Antioxidants in your body counteract the action of free radicals.
Rust and rot are both oxidative mechanisms. Many human tissues are also susceptible to oxidation, especially those containing polyunsaturated fats. Exposure to environmental pollutants such as smoking, smog, and irradiation increase oxidation. In fact, most scientists believe that oxidative damage is a major factor in most degenerative diseases of aging, such as heart disease, cancer, and macular degeneration. During life, our tissues would be susceptible to similar processes, except for the intervention of a variety of antioxidants. The antioxidant defense system is a network of vitamins (C, E), minerals (selenium, copper), phytonutrients (beta-carotene, lycopene, lutein), and biological products (bilirubin, coenzyme Q10) that protect tissues from oxidative damage (Jacob and Burri, 1996).
Citrus fruits contain a variety of carotenoids. Pink grapefruits have a high content of lycopene and te-carotene, while other citrus (such as tangerines, oranges) contain high levels of different carotenoids (lutein, zeaxanthin, te-cryptoxanthin)34 that have significant antioxidant activity. These carotenoids are associated with a lower incidence of age-related macular degeneration,45 the leading cause of vision loss in Americans after the age of 55. A diet rich in carotenoids (such as lutein, zeaxanthin or te-carotene) enhances several aspects of immune function in the body, including those linked to tumor cell destruction.46
In a December 2007 report, the UK Human Genetics Commission (2007, Appendix 2) identified 26 companies based in the USA, UK and Europe that advertise and or sell DTC genetic tests. While not an exhaustive count of the number of firms currently operating in this field, the tests provided by these 26 companies reveal the range of health concerns for which testing is available and the variable models by which services are offered. DTC tests assess genetic predisposition for a range of diseases and conditions, including cancer (mainly breast, ovarian, prostate and colorectal cancer), cardiovascular disease, osteoporosis, diabetes (type 1 and type 2), obesity, celiac disease, inflammatory bowel disease, hemochromato-sis, factor V Leiden, thrombophilia, glaucoma, macular degeneration and Alzheimer's disease. They may test for genetic factors that affect lipid, glucose, caffeine, alcohol and pharmaceutical metabolism. Pregnancy and newborn screening tests are also available. Some tests are...
Now that we know that excessive glutamate in the eye can cause damage to the retina, what about other eye disorders, such as retinal detachment, inflammatory diseases of the eye, trauma, macular degeneration, infectious diseases of the eye and cataract Cataracts are the result of free-radical damage to the proteins in the lens, and so would be susceptible to excitotoxic damage.
To maintain good eyesight foods rich in vitamins A, C, E, riboflavin, selenium, and zinc should be consumed. All these nutrients are important for vision and are supplied by a balanced diet with generous amounts of fruits and vegetables, such as carrots, cantaloupe, oranges, and broccoli. Generous intake of antioxidant nutrients (see pp. 115) over a lifetime may help prevent cataract, the most common cause of impaired vision in older adults.1 Age-related macular degeneration (AMD) is a common cause of vision impairment in older people, and the risk of AMD can be reduced by a diet high in antioxidants, ca-rotenoids, and zinc.2 3 Nutrient supplementation may help correct minor eye troubles such as dry, burning, itchy eyes and eyestrain.
Carotenoids are a group of red and yellow fat-soluble compounds that pigment different types of plants, such as flowers, citrus fruits, tomatoes, and carrots, as well as animals, such as salmon, flamingos, and goldfish. The ingestion of carotenoids is essential to human health, not only because some convert into Vitamin A, but also because they have antioxidant effects, which may combat such diverse problems as cancer and macular degeneration. Carotenoids also help prevent heart disease by inhibiting low-density lipoprotein (LDL) cholesterol (the bad cholesterol) from sticking to artery walls and creating plaques. Lycopene is a carotenoid that offers protection to the prostate and the intestines. It has also been associated with a decreased risk of lung cancer. Found in tomatoes, it remains intact despite the processing involved in making ketchup and tomato paste. The carotenoids lutein and zeaxanthin seem to aid in the prevention of cataracts and macular degeneration, and can be...
Vitamin A is the moisturizing nutrient that keeps your skin and mucous membranes (the slick tissue that lines the eyes, nose, mouth, throat, vagina, and rectum) smooth and supple. Vitamin A is also the vision vitamin, a constituent of 11-cis retinol, a protein in the rods (cells in the back of your eye that enable you to see even when the lights are low) that prevents or slows the development of age-related macular degeneration, or progressive damage to the retina of the eye, which can cause the loss of central vision (the ability to see clearly enough to read or do fine work). Finally, vitamin A promotes the growth of healthy bones and teeth, keeps your reproductive system humming, and encourages your immune system to churn out the cells you need to fight off infection.
Bilberry extract is prescribed in Europe for eyesight, particularly night vision. This health benefit is the primary reason for the product's popularity in Japan and Korea, where it is used to relieve computer-induced eyestrain (Kalt and Dufour, 1997). This benefit may be due, in part, to the small amounts of carotenoids present in the fruit. However, a double-blind, placebo-controlled study demonstrated that oral doses of anthocyanins are important for regeneration of visual purple (Alfieri and Sole, 1966). Bilberry extracts appear to benefit vision in several ways improved night vision by enhanced regeneration of retinal pigments, increased circulation within the capillaries of the retina, inhibition of Maillard reactions in the lens to reduce cataract formation, and protection from ultraviolet light. The antioxidant properties of V. myrtillus extracts may be responsible for these health benefits. Antioxidants have been suggested to retard oxidation in the lens and to slow retinal...
Epidemiological studies have implicated the macular pigment in the reduction of risk for the neovascular form of age-related macular degeneration (AMD) (Seddon et al., 1994). Dietary intake of lutein and zeaxanthin is associated with a 43 reduction in risk of advanced neovascular AMD for individuals in the highest quintile of intake. Similarly, a study of serum levels reveals the same association (EDCCSG, 1993). More recently, through a study of postmortem retinal samples, we have demonstrated that higher retinal levels of macular carotenoids are associated with a reduction in the odds ratio for the occurrence of AMD (Bone et al., 2001). Further, we have demonstrated through supplementation studies that macular pigment optical density is related to serum lutein and zeaxanthin levels. High doses of lutein produce macular pigment increases in the range of 20-40 (Landrum et al., 1997). Indeed, it is even possible to modulate the level of macu-
