Eating fish regularly may reduce the likelihood of developing the untreatable hearing disorder known as tinnitus, according to a recent study.
A research group from Brigham and Women's Hospital in Boston, U.S., studied data from 73,000 patients concerning the occurrence of this condition, affecting countless individuals across Britain who experience persistent ear noises like humming or ringing.
During a 30-year span, individuals who consumed over two portions of fish weekly exhibited nearly a 25 percent reduced likelihood of experiencing tinnitus compared to those who seldom or never ate fish.
People who consumed one serving of fish weekly experienced a 13 percent reduced risk.
Tuna, along with lean meats like cod or halibut, and shellfish were linked to a reduced risk of tinnitus. However, fatty fishes such as salmon and swordfish seemed to elevate the likelihood of experiencing tinnitus.
Supplements of fish oil — often consumed due to their benefits for cardiac, cognitive, and joint health — were likewise linked to an increased likelihood of experiencing tinnitus.
It is estimated that approximately 15 percent of adult Britons experience tinnitus.
Although tinnitus is often associated with age-related hearing loss, injuries to the ear, or problems related to blood circulation, the exact cause remains unclear.
Earlier research has linked diet to an increased risk of tinnitus, suggesting that higher levels of calcium, iron, and fats might elevate this danger. However, the latest study is the first to offer comprehensive data spanning such an extensive period.
Seafood has also been demonstrated to decrease the likelihood of hearing loss; according to a study released earlier this year, consuming greater amounts of fish could cut down the risk of encountering hearing issues by as much as 20 percent.
Researchers think that omega-3 fatty acids present in fish could aid in safeguarding cell health within the inner ear or ease inflammatory reactions caused by loud sounds, substances, or infections.
The research group from a Boston hospital, who conducted their study using data from American female nurses, aims to assist potential future cases of tinnitus by exploring the connection between consuming fish and experiencing this condition.
The study’s authors noted that 'pinpointing adjustable elements affecting the likelihood of ongoing tinnitus might help in both preventing it and developing specific treatments.'
