A number of studies have linked acular degeneration to damage caused by harmful free radicals, which are combated by antioxidants such as vitamins C, E, and A, beta carotene, zinc, and selenium. Other research has found that the balance of fatty acids in the eye can influence macular degeneration risk, possibly by affecting the degree of inflammation.
Both saturated fatty acids (from animal fats) and monousaturated fatty acids (from olive and other oils) have been found to slightly increase macular degeneration risk, while higher amounts of polyunsaturated omega-3 fatty acids from fish, which are anti-inflammatory, appear to slightly decrease risk. The new study, published in Archives of Ophthamology, include 4,519 people between 60 and 80 years old. After completing eye exams, the people were divided into four groups depeneding on the severity of macular degeneration. The results of dietary uestionnaires were analyzed within each group.
People who reported eating more than one serving of baked or beoiledfirsh per week were 35% less likely to have advanced macular degeneration than those who ate less than one servig of fish per month. The pople with the highest intake of omega-3 fatty acids were found to be 40% less likely to be in the advanced macular degeneratoin group than those witht he lowest intake. Of the omega-3 fatty acids, DHA (docosahexaenoic acid, one of the primary fatty acids from fish) gave the strongest protection.
While eating fats from fish seemed to protect against macular degeneration, eating high amounts of omega-6 fatty acids from animal fat seemed to increase the likelihood of having macular degeneration. “It is important to consider the balance and composition of dietary [fats] from the omega-3 and omega-6 families, “the study’s from other [studies] stuggest that modifying the diet to include more foods rich in omega-3 fatty acids could result in a reduction in the risk of having [advanced] age-related macular degeneration.”

FISH OIL STORY
Studies have shown that fish oil may well be he closest thing to a cure-all the world of nutrition has to offer. It lowers triglyceride levels and blood pressure, normalizes heart rhythm, prevents heart disease and sudden cardiac death, reduces inflammation and treats chronic inflammatory conditions such as allergies and autoimmune diseases, and prevents some cancers.

FISH OILS BENEFICIAL DURING PREGNANCY
“During pregnancy, large amounts of DHA and arachidonic acid are deposited in the fetal retina and brain,” said Susan L. Prescott, MD, PhD, of the School of Pediatrics and Child Health, University of Western Australia. “These fatty acids, found in fish oil, seem to be critical for normal nervouc system and visual development.”
