I'm always on the lookout for a tinnitus solution, or mitigation. The posts above about caffeine (I drink quite a bit in the morning) and other dietary changes prompted me to do a few quick PubMed searches. It seems that the studies on the topic are mainly observational, and that the conclusions about diet association are mixed. The study below actually says that caffeine
may decrease tinnitus.
As with many things, YMMV, and it's pretty easy to cut out caffeine to see if there is a change for you. Same with eating more fruit, fiber and dairy.
FWIW/FYI here are two paragraphs (minus footnotes) from the study linked below. First about caffeeine, then the overal conclusion. (Bold emphasis is mine.)
The association between caffeine intake and tinnitus remains contentious. Our findings indicate that caffeine has a positive effect on tinnitus incidence. Some suggest that caffeine might effectively decrease tinnitus incidence, possibly because of its anxiety-reducing effects. Conversely, some scholars argue that individuals with tinnitus often experience insomnia, in which caffeine consumption could worsen, thus exacerbating tinnitus symptoms. Recent observational studies have revealed no link between caffeine consumption and depression or anxiety levels. Furthermore, additional dose analysis revealed a J-pattern association between caffeine intake and psychiatric disorders, with about 2–3 cups per day associated with decreased risk. Caffeine, which acts as a non-selective adenosine receptor antagonist, can mitigate anxiety when it is ingested at a daily dose of 10 mg/kg. Genetic analysis also suggested a correlation between caffeine consumption and reduced tinnitus incidence. This effect is achieved through adenosine receptor blockade, dopamine release promotion, acetylcholinesterase activity inhibition and sympathetic nerve stimulation.
Diet-based strategies for tinnitus prevention are anticipated to play a significant role in chronic tinnitus management. Existing evidence suggests that consuming fruit, dietary fibre, caffeine and dairy may be associated with a reduced incidence of tinnitus. 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. However, it is crucial to interpret our findings cautiously because of the overall low quality of the evidence available. In the future, further well-designed, large-scale, cross-population cohort studies are warranted to complement and verify the relationship between dietary intake and tinnitus. Additionally, focusing on the dosage and categorisation of each dietary intake would provide valuable insights.
A systematic analysis was conducted to investigate the association between tinnitus incidence and daily dietary patterns. We conducted a systematic review and meta-analysis of observational studies. The PubMed, Embase, Web of Science and Cochrane ...
