Fruit, Fiber, Dairy, and Caffeine Tied to Lower Tinnitus Risk, Study Finds - Video
|
Overview
Increased consumption of fruit, dietary fibre, dairy products and caffeine may be associated with a reduced risk of tinnitus (ringing in the ears), suggests an analysis of the available evidence, published in the open-access journal BMJ Open.
Tinnitus is the perception of sound (ringing, buzzing or clicking) when there’s no external source. Data suggests it affects around 14% of adults worldwide and is associated with depression, anxiety, stress, and in severe cases, suicide.
Diet can also have a significant impact on tinnitus. It’s thought that eating high-quality nutrients can have a positive effect on hearing by improving blood flow to the inner ear and reducing oxidative damage and inflammation. But previous studies show conflicting results and it’s still uncertain which specific foods worsen or relieve symptoms.
They found eight observational studies involving 301,533 people that assessed 15 dietary factors using validated questionnaires that were of suitable quality to include in their analysis.The dietary factors included carbohydrates, caffeine, eggs, fruits, fibres, fat, meat, protein, sugar, fish, vegetables and dairy.
The combined findings revealed that increased consumption of fruit, dietary fibre, dairy products and caffeine was associated with a reduced occurrence of tinnitus. These reductions were 35% for fruit intake, 9% for dietary fibre, 17% for dairy products, and 10% for caffeine intake.
No associations were found between other dietary factors and tinnitus and results were consistent after further analyses, although the authors note that the association between caffeine intake and tinnitus remains contentious.
However, the authors suggest that “the primary underlying mechanisms may involve the protective effects of these diets on blood vessels and nerves, as well as their anti-inflammatory and antioxidant properties” and say further large-scale studies are needed “to complement and verify the relationship between dietary intake and tinnitus.
