FRIDAY, March 21, 2025 (HealthDay News) — Specific dietary elements, including fruit, dietary fiber, caffeine, and dairy consumption, are associated with a reduced incidence of tinnitus, according to a review published online March 18 in The BMJ.
Mengni Zhang, from the Hospital of Chengdu University of Traditional Chinese Medicine in China, and colleagues conducted a systematic review and meta-analysis of observational studies to examine the association between tinnitus incidence and daily dietary patterns. Ten retrospective studies were included in the analysis; the last eight were incorporated into the meta-analysis.
Fifteen dietary factors were assessed. The researchers found negative correlations for fruit, dietary fiber, caffeine, and dairy consumption with tinnitus incidence (odds ratios, 0.649, 0.918, 0.898, and 0.827, respectively). The robustness of the findings was confirmed in a sensitivity analysis.
“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,” the authors write. “However, it is crucial to interpret our findings cautiously because of the overall low quality of the evidence available.”
