New research has uncovered a link between the consumption of fatty acids from fish/fish oil and lower risk of hearing loss.
Acquired hearing loss—which occurs any time after birth—can result from illness (ear infections, measles, meningitis, encephalitis, mumps, etc.) and injury (excessive loud noise, head injury). Additionally, presbycusis is a common type of hearing loss that occurs gradually as a person gets older. According to some estimates, 30 million Americans had an auditory disorder in 2000.
In this study, researchers examined the association between consumption of fish and omega-3 polyunsaturated fatty acids and self-reported hearing loss in 65,215 women from 1991 to 2009.
A total of 11,606 cases of hearing loss were reported. The researchers discovered that consumption of two or more servings of fish per week resulted in a decreased risk of hearing loss. The researchers also stated that higher intake of long-chain omega-3 fatty acids was inversely associated with risk of hearing loss.
