Remember the babel fish from A Hitchhiker's Guide to the Galaxy? It lives. Reporting in the August issue of the American Journal of Clinical Nutrition, researchers with the Blue Mountains Hearing Study say that compared with people who ate less than one serving of fish a week, those who ate two or more servings were 42% less likely to develop presbycusis, or age-related hearing loss. The investigators used each person's fish consumption to estimate intakes of omega-3 (n3) polyunsaturated fatty acids, or PUFAs, and they also found that the higher the estimated intake of n3 PUFAs, the lower the risk of presbycusis.
This was a decent-sized study group of almost 3,000 people aged 50 years and older that the investigators have apparently been following since 1997. The Blue Mountains Hearing Study is out of Macquarie University in Sydney, Australia.
