Fish and Omega-3 Intake Not Linked to Hearing Loss in Large Japanese Study
Researchers analyzed diet and hearing test results from nearly 14,000 Japanese adults aged 50-79 who typically eat a lot of seafood. They wanted to see if eating more fish or omega-3 fatty acids (EPA and DHA) was linked to better hearing as people age.
After adjusting for other factors, the study found no meaningful connection between seafood intake, omega-3 intake, and hearing test results at any frequency tested. Interestingly, men who ate more saturated fat actually had slightly better (lower) hearing thresholds at certain frequencies, though this pattern was not seen in women.
The researchers noted that because this population already eats so much seafood, there may not be enough variation in intake to reveal a protective effect, if one exists. They concluded that the relationship between dietary fat and age-related hearing loss is likely more complex than previously thought and may differ between men and women.
What this means for you
This large observational study did not find evidence that eating more seafood or omega-3 fats protects hearing as we age, at least in a population that already eats a lot of fish. It’s a reminder that not every proposed benefit of omega-3s is supported by every study, and factors like sex and baseline diet can complicate the picture.
