Fish Oil Prevents Age-Related Blindness (Macular Degeneration)
In two separate studies in the US and Australia, seniors who ate more fish were far less likely to develop age-related oracular degeneration (AMD), the leading cause of vision loss for the elderly. The U.S. study, which also found a link between cigarette smoking and AMD, found “that men with the highest fish consumption (at least two weekly servings) were 45 percent less likely to have AMD than those with the lowest fish consumption (less than one weekly serving).”
The Australian study involved over 2900 people aged 49 or older. This study found that “Participants who reported eating at least one weekly serving of fish were 40 percent less likely to develop early-stage AMD during the study, compared with those who reported eating fish less than once a month or not at all… People who ate fish frequently were also less likely to have late-stage AMD, the study shows. But that pattern was only seen in participants who reported eating fish at least three times weekly.”
Fish Oil Prevents Age-Related Macular Degeneration and Dry-Eye Syndrome
I just found an article at WebMD titled, Fish Oil Benefits your Eyes, in which it discusses how two studies reported at the Association for Research in Vision and Ophthalmology (ARVO) indicate that the long-chain omega-3 fatty acids in fish oil protects the eye from two very serious eye diseases: Age-Related Macular Degeneration and Dry-Eye Syndrome. A
ccording to the article, age-related macular generation is a “disruption of the center of the retina, the fine nerve net at the back of the eye essential for all fine visual tasks. It’s the leading cause of age-related blindness.” Dry-Eye syndrome is “when a person’s eyes don’t make enough tears. This can lead to scarring of the cornea and vision loss.” It seems fish oil, especially omega-3, prevents the leading cause of age-related blindness, so if you’re worried about being able to see when you’re older, you’d best pick up some omega-3. Just make sure you’re not using health-food grade fish oil as many have metals like mercury.— Instead, pick up some MOXXOR (mercury-free) because Mercury causes blindness too!
Diet High in Omega-3 May Prevent Leading Cause of Blindness Among Elderly
Current research suggests that a diet high in omega-3 fatty acids may help prevent one of the leading causes of legal blindness among the elderly. The related report by Tuo et al, “A high omega-3 fatty acid diet reduces retinal lesions in a murine model of macular degeneration” appears in the August 2009 issue of the American Journal of Pathology.
Age-related macular degeneration (AMD), loss of vision in the center of the visual field (macula) due to retinal damage, is one of the leading causes of legal blindness among the elderly. Approximately 10% of people from 66-74 years of age will develop some level of macular degeneration, making it difficult for them to read or even recognize faces. A diet high in omega-3 fatty acids has been found to protect against a variety of diseases including atherosclerosis and Alzheimer’s disease. Retrospective studies have suggested that diets high in fish oil or omega-3 fatty acids may also contribute to protection against AMD.
A group led by Dr. Chi-Chao Chan at the National Eye Institute in Bethesda, MD examined the direct effect of omega-3 fatty acids on a mouse model of AMD. A diet with high levels of omega-3 fatty acids resulted in slower lesion progression, with improvement in some lesions. These mice had lower levels of inflammatory molecules and higher levels of anti-inflammatory molecules, which may explain this protective effect. Tuo et al suggest that “a diet enriched in EPA and DHA cam ameliorate the progression of retinal lesions in their mouse model of AMD” and that “the results in these mice are in line with the epidemiological studies of AMD risk reduction by long chain n-3 fatty acids.”
The results “further provide the scientific basis for the application of omega-3 fatty acids and their biologically active derivatives in the prevention and treatment of AMD.” In future studies, Dr. Chan and colleagues plan to use this murine model “to evaluate (other) therapies that might delay the development of AMD.” Their ongoing projects include the “testing of systemic delivered pharmacochaperones and antioxidative molecules, as well as intraocularly delivered gene therapies.” This work was supported by grants from The Intramural Research Program of the National Eye Institute, the National Institutes of Health, and the American Health Assistance Foundation.
