Tinnitus is the sound of ringing in the ears. It may also be described as roaring, buzzing, hissing, or clicking inside the head. The sounds may come and go. Or they may be ongoing. The sounds range in severity from a mild distraction to a disabling condition and may manifest with buzzing, hissing, or clicking inside the head.
The sound may happen in one or both ears and may have different tones. A team from Brigham and Women’s Hospital in Boston studied 73,000 individuals to understand how common this disorder is, which affects millions with a constant ringing in their ears.
Over a span of 30 years, those who consumed more than two servings of fish weekly had nearly 25 percent lower odds of getting tinnitus compared to those who seldom or never ate fish. Even eating just one serving a week resulted in a 13 percent reduced risk.
Certain types of fish, like tuna, light-fleshed varieties such as cod or halibut, and shellfish, were linked to a reduced risk, while darker fish like salmon and swordfish seemed to increase the risk.
Interestingly, fish oil supplements, known for their benefits to heart, brain, and joint health, were also connected to a higher risk of tinnitus. It’s estimated that tinnitus is diagnosed in almost 1 in 6 persons.
While age-related hearing loss, ear injuries, and circulation issues are known to contribute to tinnitus, the exact cause remains unclear. Previous studies have suggested that dietary factors, such as high levels of calcium, iron, and fat, might heighten the risk. However, this new research is the first to analyse data over such a lengthy period.
Past findings have also shown that seafood can lower the risk of hearing loss, with one study suggesting that increased fish consumption might reduce hearing issues by up to 20 percent. Scientists believe that the omega-3 fatty acids in fish could protect inner ear cells or reduce inflammation caused by loud sounds, chemicals, or infections.
The Boston team’s investigation, based on a database of US nurses, aims to shed light on the connection between fish consumption and tinnitus, potentially aiding future patients. The authors of the study expressed hope that identifying factors that can be changed might help in preventing tinnitus and guiding targeted treatments.
