Omega-3 Fatty Acid May Help Prevent Age-Related Hearing Loss
Eating more fatty fish and taking dietary supplements that contain omega-3 fatty acids can potentially protect against long-term hearing problems, according to a study presented at the American Society for Nutrition meeting in Boston. The research found that middle-aged and older adults who had higher levels of the omega-3 fatty acid DHA were less likely to report age-related hearing issues than those with lower DHA levels. These nutrients are commonly found in foods such as salmon, walnuts, and flaxseed.
Study Finds People with Higher DHA Levels Have Better Hearing
In a study of over 100,000 adults in the UK aged 40-69 years, researchers analyzed self-reported hearing status and blood DHA levels. Participants with higher DHA levels had a reduced likelihood of reporting hearing difficulties or trouble following conversations in noisy environments. However, the study does not prove that DHA maintains auditory function or that low DHA levels cause hearing loss.
Omega-3 Fatty Acids May Help Improve Hearing by Reducing Inflammation
New research supports previous evidence indicating that omega-3 fatty acids may aid in reducing inflammation in blood vessels and potentially improve hearing. Dr. David R Friedmann, a neurotologist at NYU Langone Medical Center, explains that the study aligns with previous findings that suggest omega-3 is good for vasculature and inner ear health. If the primary source of blood for the inner ear, the labyrinthine artery, becomes obstructed by plaque or vascular disease, it could result in hearing loss. While increasing intake of omega-3 acids to benefit ear health seems plausible, Friedmann emphasizes that the study does not provide definitive recommendations.
Tips for Increasing Omega-3 Fatty Acids Intake
According to McBurney, individuals looking to boost DHA levels can regularly consume seafood, take dietary supplements, or do both. Fatty fish like salmon, sardines, and anchovies are great sources of long-chain omega-3 fatty acids such as EPA and DHA. However, those who avoid fish or have concerns about mercury pollution can consider taking fish oil or vegetarian algal capsules. To ensure effectiveness, select supplements that provide higher amounts of EPA and DHA per serving, which should be indicated on the product labels.
