In that hearing loss is a widespread sensory condition that generally impacts with age, Paul Mitchell, from the University of Sydney (Australia), and colleagues analyzed data collected on 2,956 men and women enrolled in the Blue Mountains Hearing Study, surveying the subjects regarding their dietary intakes of fish.  The team found that two servings of fish weekly reduced hearing loss in subjects ages 50 years and older, compared with people who average less than one serving per week.  Writing that: “There was an inverse association between higher intakes of [omega-3 fatty acids] and regular weekly consumption of fish and hearing loss,” the researchers conclude that: “Dietary intervention with [omega-3 fatty acids] could prevent or delay the development of age-related hearing loss.”
