Fish oil might be good for AMD

The UK's Daily Mail (7/24, Hope) reports that, according to a study "to appear in the American Journal of Pathology next month," foods "containing omega 3 and fish oils may help prevent" age-related macular degeneration (AMD), "the most common cause of blindness in old age." For the study, researchers at the National Eye Institute "fed mice with high levels of omega 3," and "found those eating more fish oils had lower levels of AMD." In fact, "the condition improved in 57 percent of mice fed the highest levels for at least 12 weeks, compared with just four percent on lower levels of omega 3." While it remains unclear "how omega 3 works," the investigators theorize that "the mechanism may be anti-inflammatory."

The UK's Telegraph (7/23, Smith) reported that prior research conducted by a team from Tufts University "found that a diet rich in omega three, found in mackerel and salmon, can reduce the risk of developing macular degeneration by a third in humans." In the Tufts study, researchers found that "progression of advanced disease was 25 percent less likely in those eating two portions of oily fish a week." (courtesy AOA)
