More evidence that fish oils help protect us from vision loss and going blind
Researchers compared results of 3 prospective studies (forward looking studies of specific individuals), 3 case control studies (these compare people with a condition to people without it) and 3 cross sectional studies (looking at a point in time and estimating a disease in this population) all published prior to May 2007 for a current review. The studies involved a total of 88,974 men and women of which 3,203 had age-related macular degeneration; the major cause of blindness in the elderly.
Analysis of the nine studies shows that a high intake of Fish Oil Fatty Acids (EPA and DHA) decreases the risk of sight robbing advanced macular degeneration by almost 40% compared to those with a low intake. Due to limited data (few people with) the researchers were not able to gauge the protective benefits of Fish Oils and earlier stages of macular degeneration. Those who ate fatty fish twice a week also benefited having a 33% lower risk. Information was available for fish intake and earlier stage macular degeneration giving a 24% lower risk. The study is published in the June 2008 issue of the American Medical Association journal Archives of Ophthalmology.
